The structure-activity relation of synthetic dehydrophenylahistin (dehydrogenation PLH) derivative
1) general introduction during derivative synthesizes
Many in the dehydrogenation PLH derivative disclosed herein (but not being whole) have one, two or three modification group (seeing following Fig. 5) on its phenyl ring.Described derivative is by the aforesaid method synthetic.As shown in table 5, some compound exhibits goes out than dehydrogenation PLH and the higher cellular cytoxicity activity of tBu-dehydrogenation PLH.Active the highest, EC 50Value is KPU-90 for the compound of 3nM.Above-mentioned value is higher 16 times and 4 times than the numerical value of dehydrogenation PLH and tBu-dehydrogenation PLH respectively.These derivatives have single replacement in an ortho position or a position of described phenyl ring, and substituting group is halogen atom (as fluorine and chlorine atom) or methyl, vinyl or methoxy group.On heteroaryl structure, have substituent derivative and also have effective activity such as naphthalene, thiophene and furan nucleus.KPU-35,42,69,80 and 81 also shows the activity that is higher than tBu-dehydrogenation PLH.

2) on described phenyl ring, introduce methoxy group
Colchicine can be discerned binding site identical on β-tubulin with PLH.Colchicine has 4 feature methoxy group on its A and B ring.Carried out a series of mono methoxies or Polymethoxylated replacement, the result is as shown in table 6 for its cellular cytoxicity activity.

The above results proves in a position or adjacent replaces the cellular cytoxicity activity rising that makes the HT-29 cell.KPU-9 and 16 demonstrates high reactivity.Have trisubstituted methoxy derivatives (KPU-11,17 and 45) and also demonstrate activity.The structure of KPU-24 is determined by mass spectroscopy.
3) modify with electron withdrawing group
For the structure-activity relation on the described widely phenyl ring of research, introduced a series of different functional groups, comprise electron withdrawing group and donor residues.To the cytotoxicity result of HT-29 cell respectively shown in table 7 and 8.
At the ortho position or the effective enhanced activity of the replacement of a position.These results are very consistent with the situation of methoxyl group.
Table 7. electron-withdrawing group is to the effect of HT-29 cell proliferation
Table 8. Electron-donating group is to the effect of HT-29 cell proliferation
Figure S05808571920060922D001021
The disclosure is not defined or is limited to any concrete scientific theory.Yet, be to be understood that those skilled in the art can admit the conclusion that this paper presents and think that promptly less relatively functional group (that causes is sterically hindered less) can help showing stronger activity, be unfavorable for sterically hindered with for example tubulin binding site reaction and can cause such as the big slightly group of oxyethyl group (when comparing) or Br atom (when comparing) with the Cl atom with methoxyl group.In addition because these substituent characteristic electrons do not influence activity, therefore think these less relatively groups not with the binding site direct reaction of described β-tubulin, but limited the conformation that is suitable for above-mentioned bonded dehydrogenation PLH.Perhaps, as another possible hypothesis, because introduce hydrophilic oh group (it can be used as hydrogen donor and forms hydrogen bond) activity is significantly reduced, so hydrophobic property may be prior factor at the binding site to ortho position on described β-tubulin or contraposition.
As shown in table 9, can put in order the active effect of ortho-substituent pair cell toxicity, and as shown in table 10 to the situation of meta-substituent.Also can further modify compound with effective functional group (it demonstrates the high reactivity more than tBu-dehydrogenation PLH).And because the stereochemistry from Z to E that observes under radiation of visible light changes, the substituting group that therefore can reduce the electron density of described conjugated double bond can reduce the Z that caused by the light transformation to E, thus stable structure more on the generation physical chemistry.Temperature also can influence this transformation.
Modify the compound that can help developing effective and bio-stable in two parts of described ring.The phenyl ring of described phenyl ahistins can be by the cytochrome P-450 oxidation.Therefore, the double modification that can reduce the electron density of described phenyl ring can be avoided the oxidation of P-450 effectively.Therefore, with described little electron-withdrawing group (as fluorine atom) but with the unit of enhanced activity (as-OMe ,-Me ,-Cl ,-F and Br) combine, can produce the medical compounds of more effective and bio-stable.

4) with the described phenyl ring of aryl-heterocyclic substituted
Described phenyl ring also can be substituted by heteroaryl groups.The cellular cytoxicity activity result that this class is replaced is as shown in table 11.Because the nitrogen-atoms of described aromatic ring can form hydrogen bond with the NH group of described piperazinedione ring, and the molecular conformation that limits described pyridine and piperazinedione interannular is the monoplane structure, so the activity conformation of dehydrogenation PLH needs between the ortho-hydrogens atom of the hydrogen atom of acid amides of described piperazine ring and described phenyl ring to form by steric exclusion a certain size interfacial angle.

Substitute described phenyl ring (for example KPU-29 or 42) with less furans or thiphene ring and can show activity.Keeping to change described phenyl ring into other aromatic structure under the stronger active condition.
5) metabolism of phenyl ahistins
In recent research, (±)-phenyl ahistins is handled with rat liver microsome or people's liver P450s.In people's situation, detect seven kinds of meta-bolitess at least, and wherein two kinds (they being P1 and P3) be main meta-bolites, what account for described recovery meta-bolites surpasses 60%.
Since outside in tBu-dehydrogenation PLH, not having-and alkene structures, so current synthetic derivative does not resemble the oxidised form of P1 and P4.But, in the liver metabolism process, form oxidised form such as P3 and P5.The various metabolic derivatives of this class that stop can be avoided P450 oxidation on described phenyl ring effectively.Also can modify to avoid disadvantageous oxidation described imidazole ring.
6) physical and chemical stability of dehydrogenation PLH
The physical and chemical stability of dehydrogenation PLH is one of disadvantageous problem.In the phenyl ahistins,, therefore there is not this class problem because do not have other alkene structures at described benzyl moiety.Yet in dehydrogenation PLH, described benzylidene part can be easy to be activated (may by visible-light activated), and because there is the long conjugation of two keys, therefore the transformation of Z to E often takes place.This transformation even under normal indoor light, also can take place.In described cytotoxicity analysis, some compounds change the E-type in the process of hatching, although this transformation may reach the balance of 1: 1 ratio to dehydrogenation PLH.This transformation is controlled.Knownly in combretastatin A4 (similar type of tubulin inhibitor), also there be the transformation of this Z, and reported that some improve the research of this problem to E.
7) prodrug is synthetic
The E-type also can be used as the prodrug of dehydrogenation PLH or one or more its analogues (comprising those analogues as herein described).Although anti-tubulin medicine belongs to one of molecular targeted methods of treatment, one of unfavorable characteristic of these medicines comprises its lower selectivity to tumour and health tissues.This has caused disadvantageous side effect.Yet,, can reduce the adverse side effect of anti-microtubule medicine if described compound is only optionally brought into play function in tumor tissues.Because described dehydrogenation PLH (Z-type) can be produced by radiation of visible light by its E-isomer, therefore can be with the administration of described E-type and only knub position is carried out rayed, have only tumour to be damaged like this, and reduced counter productive health tissues by the Z-type that light produces.
By introducing large volume but biodegradable carboxyl groups can carry out chemoproection to described E-type, and described carboxyl groups can be used as prodrug and introduces on the described piperazinedione ring.This class carboxyl groups can be by intravital proteasome degradation.Therefore, keep the E-compound of acylations before administration, it becomes real E-type after the administration, it can be changed into bioactive Z-type by the local light irradiation.
The synthetic route of the tBu-dehydrogenation PLH of this class acyl group-E-type as shown in Figure 9.

A main challenge using chemotherapy agents in Clinical Oncology is the resistance of tumour cell to described drug effect development.Chemical sproof development has multiple mechanism, and wherein each all has different effects to chemotherapeutics.These mechanism comprise that the expression of the efflux pump (efflux pump) that ATP relies on rises, and described efflux pump is the P-glycoprotein of MDR1 coding or the multiple drug resistance associated protein 1 of MRP1 coding for example.Ingestion of medicines reduces, drug targets changes, acceleration reparation, the change of apoptosis pathway and the activation of cytochrome P 450 enzymes of drug-induced dna damage are cancer cell produces chemical sproof mechanism to cancer therapy drug other examples.In three kinds of different clones of two kinds of different resistance mechanism of performance (crossing of P-glycoprotein expressed and the active change of topoisomerase II), selected compounds is studied.
1) People's sarcoma of uterus tumor cell line is right: MES-SA (taxol sensitivity) and MES-SA DX are (anti- Taxol)
Mdr-1 mRNA and P-glycoprotein (overboard pump mechanism) that this expression of cell lines raises.Cause chemical sproof compound to raising, with S-Neoral-A (CsA) pre-treatment P-glycoprotein capable of blocking and recover the activity of those compounds in described drug-resistant cell is by P-glycoprotein.
As shown in table 13, KPU-2 has identical intensity with KPU-35 in the described sensitivity of described drug-resistant cell system's neutralization system, descend and the intensity of tert-butyl-phenyl ahistins is just slight.The intensity of S-Neoral-A (CsA) pre-treatment can not change selected compounds.Different with it, taxol is actually non-activity in described MES-SA DX drug-resistant cell system, and this compound is very potent in described sensitive cell line.CsA handles and has recovered the susceptibility of described MES-SA DX clone to taxol.Described MES-SA DX clone also demonstrates the susceptibility of reduction to etoposide (etoposide) (60 times), Zorubicin (34 times) and mitoxantrone (mitoxantrone) (20 times).
These data show, the effect of KPU-2, KPU-35 and tert-butyl-phenyl ahistins is not subjected to the influence of the relevant resistance mechanism of this described taxol (p-glycoprotein) in described clone, shows that simultaneously there is not cross resistance in taxol to these selected compounds in this model.
Table 13. KPU-2, KPU-35, tert-butyl-phenyl ahistins and taxol are at the MES-SA Japanese yew Activity in people's sarcoma of uterus tumor cell line of alcohol sensitivity and the anti-taxol of MES-SA DX5
Also referring to the other data shown in Figure 43.
2) The acute promyelocyte leukemia cell of people is right: HL-60 (mitoxantrone-sensitivity) and HL-60/MX-2 (anti-mitoxantrone)
This clone is considered to have atypical resistance, has the topoisomerase II catalytic activity of change and does not have cross expressing of P-glycoprotein.
As shown in table 14, these results show that the intensity of selected new compound is very similar in described sensitivity and resistance HL-60 clone.Different with it, mitoxantrone is renderd a service in resistance HL-60/MX-2 clone and has been descended 24 times.
Therefore, KPU-2, KPU-35 and tert-butyl-phenyl ahistins are insensitive to the resistance mechanism of mitoxantrone in this clone, show that simultaneously mitoxantrone does not have cross resistance to these selected new compounds in this model.

3) MCF-7 is right: MCF-7 (taxol sensitivity) and MCF-7/ADR (anti-taxol)
This research compares KPU-2 and taxol.KPU-2 proof has similar intensity in right sensitivity of this clone and resistance member.Different with it, taxol non-activity in fact in described drug-resistant cell system, and in described sensitive cell line, have low nmole intensity (table 15).
These researchs are confirmed can not be transferred to KPU-2 to the resistance of taxol in the different people tumour cell.

C) The research of the mechanism of action
1). to the effect of microtubule function
End user's huve cell in this research (from the HuVEC of Cambrex), by α-tubulin is dyeed, contrast colchicine and taxol have been estimated KPU-2 and the tert-butyl-phenyl ahistins effect to tubulin.
In described HuVEC cell, be exposed to KPU-2, tert-butyl-phenyl ahistins or colchicine (being 2 μ M) and induced microtubule depolymerization effect relative (show as and lack complete micro-tubular structure) and cytolemma to blister (blebbing) (apoptotic distinguishing mark) in 30 minutes, and taxol can not be induced the microtubule depolymerization effect under these conditions with observed result in the DMSO contrast.Colchicine is a known microtubule depolymerization reagent and taxol is the tubulin stablizer.The CCD-27sk cellular exposure be can be observed similar result in KPU-2 or colchicine.
2). cell death inducing
Apoptosis and insufficiency of accommodation thereof play an important role in oncology; The necrocytosis of selective induction sequencing circulation is the target of many chemotherapeutics development projects in tumour cell.By this inducing action of the provable pair cell apoptosis of different methods, aforesaid method comprises that distinctive cytolemma is blistered, dna break, the peroxophosphoric acidization of anti-apoptosis factor Bc1-2, the activation of caspase (apoptotic proteins enzyme) cascade reaction and the degraded of many (ADP ribose) polysaccharases (PARP).
Obviously different with the death of non-viable non-apoptotic cell, the characteristic signal of apoptotic cell death comprises that cytolemma is blistered, nuclear decomposition, cellular contraction and cohesion and final necrocytosis.KPU-2 induces the representative configuration relevant with the apoptosis commitment to change in the human prostate tumour cell.Can know the discovery similar phenomenon when handling the HuVEC cell with KPU-2.
3) .DNA fracture
Apoptotic late stage feature is a dna break between nucleosome, and it causes the tangible trapezoidal pattern that can be manifested by gel electrophoresis.This method is used for studying Jurkat cell (HTL system) compares the effect of KPU-2 with dehydrophenylahistin (KPU-1) dna ladder shapeization (laddering) with halimide.KPU-2 is in trapezoidalization of 1nM concentration inducing DNA, and the intensity of halimide and KPU-1 is much lower.
4) activation of .Caspase cascade reaction
In apoptotic process, comprise in the caspase cascade reaction that Caspase-3 ,-8 and-9 plurality of enzymes are activated.In the Jurkat cell, after handling, the Caspase-3 activity is monitored with KPU-2, KPU-35 and tert-butyl-phenyl ahistins.
The result shows, by to handle with all three kinds of compounds with the similar mode of halimide caspase-3 is activated in dose-dependent mode.In described Jurkat clone, with the Cytotoxic IC50 similar concentrations scope of expression in the activation (table 16) of described caspase-3 takes place.
Table 16. KPU-2, KPU-35 and the cell toxicant of tert-butyl-phenyl ahistins in the Jurkat cell The property
5) degraded of many (ADP ribose) polysaccharases (PARP) in the .Jurkat cell
In order to assess these compounds apoptosis-induced ability in the Jurkat cell, the degraded of many (ADP ribose) polysaccharases (PARP) is monitored.PARP is the nucleoprotein of 116kDa, and it is one of target in the main cell of Caspase-3.The degraded of PARP produces stable 89kDa product, and this process can be at an easy rate by the western marking (blotting) monitoring.PARP is one of apoptotic sign by the caspase degraded, and itself can be used as the good sign of this process.In described compound after 10 hours, the KPU-2 of 100nM can induce the degraded of PARP in the Jurkat cell with described cellular exposure.KPU-2 demonstrates than halimide or the higher activity of KPU-1.
6). enhanced vascular permeability in the HuVEC cell
(for example combretastatin A-4-phosphoric acid ester ZD6126) once demonstrated the interior blood vessel atrophy of induced tumor in vivo to the compound of depolymerization microtubule.Before the blood vessel atrophy, the perviousness of rapid induction of vascular cell (being at first) to developing macromole after the ionogen rapidly.With the HuVEC cell the infiltrative of fluorescently-labeled dextran strengthened as the indirect analysis to the blood vessel atrophy.
KPU-2, KPU-35 and tert-butyl-phenyl ahistins all rapid (in 1 hour) are induced tangible HuVEC mono-layer osmotic, and its degree and colchicine are similar.Microtubule stabilizer taxol non-activity (Figure 12) in this analysis.
7). the overview of kinases examination on a large scale
At first, in one group of 60 kinds of different kinases, KPU-2 is carried out examination with the concentration of 10 μ M; The concentration of ATP is 10 μ M.Four kinds of kinases are suppressed and surpass 50% in elementary examination, and the IC50 value of determining in the secondary examination is shown in table 17.All IC50 values all belong to low micro-molar range, show these kinase whose inhibition with active irrelevant to the observed low nmole of cytotoxicity.

The result
Clone tumour xenogenesis skin HT-29 people and suppress research in the model
1.KPU-2+/-CPT-11 clones interior evaluating in the tumor xenogeneic graft model HT-29 people
Dose intensity when this research is used in combination to independent use KPU-2 or with relevant chemotherapeutics CPT-11 in the HT-29 model and the variation of dosage are assessed.
With 7.5mg/kg ip once a day totally five days (qdx5), totally five days, per two days one time 7.5mg/kgip of twice on the one 3.75mg/kg ip totally 10 days (qodx5) and per three days one time 7.5mg/kg ip the dosage of totally 15 days (q3dx5) with the KPU-2 administration.CTP-11 is combined dosed administration with 7.5mg/kg ip q3dx5 can produce effect when obviously using separately greater than arbitrary compound with NPI-2358, it all remains (Figure 13) in whole research process.The average final tumor weight of the group of these observed results that the live body of this research partly obtains during by postmortem confirms, wherein has only to compare with control group in conjunction with group to show the significant lower tumor weight of statistics.In addition, the average tumor weight differential of described combined treatment group and CPT-11 treatment group separately is statistics significant (Figure 14).After when postmortem, the final tumor weight of individuality being tested, can know the bigger effect (Figure 14) of seeing combined therapy.The TGI of combined therapy be 78% and relatively separately CPT-11 be 38.9%.The TGI of combined treatment group has surpassed the NCI standard (58%) of positive effect.
2.KPU-2+/-standard chemotherapeutics is to five kinds of people's tumor xenogeneic graft Study of model
This research is made up of five parts, and every part has its scheme, arrangement of time, dosage and reference compound separately.Each part all is interpreted as being included in the description of concrete tumor model.
The purpose of the HT-29 of this research part is that research is cloned to use in the tumor xenogeneic graft model HT-29 people and compared the effect of the KPU-2 of high dosage slightly with used dosage in the above-mentioned research, wherein observes the obvious synergistic effect between KPU-2 (7.5mg/kg ip q3dx5) and CPT-11 (100mg/kg ip qwx3).
As shown in Figure 15, KPU-2 and CPT-11 are combined in this model the obvious synergistic effect when suppressing tumor growth, and suppressed fully basically at the 29th a treatment day tumor growth this moment in described combined treatment group.Combined treatment has lasting effectiveness, and the tumor growth of estimating in this group is starkly lower than arbitrary single therapy group.Therefore, KPU-2 and CPT-11 administration can be suppressed tumor growth, be the effective antitumour therapy.
The weight measurement of the tumour of excising during postmortem (Figure 16) supported this research live body part observed result (tumor growth of estimation, Figure 15).Tumor weight in conjunction with group is starkly lower than control group (p<0.01), equally also is starkly lower than the tumor weight (p<0.05) of independent use CPT-11 group.
When considering individual final tumor weight (Figure 16), in conjunction with the tumor size of organizing generally less than other treatment group or control group.TGI in conjunction with group is 65.8%, shows positive effect according to the NCI standard, and separately treatment does not reach TGI〉58% NCI standard.

Research in the DU-145 human prostate tumor xenogeneic graft model
Finished two researchs with this model: first research comprises independent use KPU-2 and it is used in combination with taxotere; Second research will be used KPU-2, KPU-35 and tert-butyl-phenyl ahistins separately and be used in combination taxotere and compare.
1.KPU-2 be combined in work in the DU-145 human prostate tumor xenogeneic graft model with taxotere With
Can find from the data (Figure 21) of this research live body part gained, be that KPU-2 and taxotere combination are treated to the most effective methods of treatment of DU-145 human prostate tumour.Effect in the described treatment of the initial stage of this research is the most remarkable, but along with the carrying out of research constantly reduces.From 20-27 days of treatment, described combined treatment demonstrated the tangible TGI above NCI standard (TGI 〉=58%) really, and the estimation tumor weight of described combined treatment also is starkly lower than each independent methods of treatment.
2. independent KPU-2, KPU-35 and tert-butyl-phenyl ahistins or itself and taxotere are combined in Activity in the DU-145 human prostate xenograft models
Based on the data that combine with taxotere by KPU-2 in the above-mentioned research and obtain, carried out second research, independent use KPU-2, KPU-35 and tert-butyl-phenyl ahistins and the difference that is used in combination taxotere have been compared in this research.
The observed result of this research live body part shows no matter be KPU-2 or KUP-35, and it combines reduction effect to tumor growth all much larger than independent use taxotere (Figure 22) with taxotere.KPU-35 combines with taxotere and has hindered described growth of tumor basically fully.
The tumor weight that excises during postmortem has confirmed the observed result in this research live body stage.Be combined in when hindering tumor growth KPU-2 (Figure 23) or KPU-35 (Figure 24) and taxotere all obviously effective than independent use taxotere.When using KPU-35, three signs that demonstrate the tumour atrophy in ten mouse.Tumor growth suppresses index and shows that KPU-2 has significant tumor growth restraining effect (group on average=74.1%), and KPU-35 has then hindered tumor growth (organizing average=92.5%) basically fully.Independent taxotere does not then reach the positive effect standard (TGA 〉=58%) that NCI sets up.
5. the research in MCF-7 human breast tumor xenogeneic graft model
KPU-2, KPU-35 and the effect of tert-butyl-phenyl ahistins in MCF-7 human breast tumor xenogeneic graft model have been compared in this research.The the 1st, 2,3,4 and 7 day with given dose with described compound administration; At the 1st, 3 and 7 day with the taxotere administration.
In this model, when selected compounds is used in combination with taxotere, have onset early, statistics acts on significantly, obviously hindered estimated tumor growth (Figure 25) basically fully.In above-mentioned three kinds of compounds, KPU-2 is shown as the most effective, and the tert-butyl-phenyl ahistins also demonstrates obvious strong effect of crossing taxotere.
6. the research in A549 people's non-small cell lung tumor xenogeneic graft model
The observed result in this research live body stage (Figure 26) shows, compares with arbitrary single therapy group with control group, and (7.5mg/kg ip qdx5) has produced significant inhibition with being used in combination of taxotere to tumor growth to KPU-2.The tumor weight that postmortem obtains has confirmed The above results, and wherein the mean value of combined treatment group is significantly less than the group of independent use taxotere or the mean value of control group (Figure 27).The tumor weight value of described combined treatment group forms one group low tumor weight, shows the persistence of described effect.
When calculating the tumor growth index, compare described combined treatment group with control group and have 74.4% TGI, far surpass the NCI standard (TGI 〉=58%) of positive effect.The use taxotere has 26.1% TGI separately.
7. the research in MDA-231 human breast tumour coordination (orthotopic) xenograft models
This model comprises to be implanted people's tumor tissues in the mouse breast buccal pad (replacer of natural surroundings).Avoided in this way by to the specific action of veins beneath the skin tissue and the positive effect that produces.This research will be used KPU-2 separately, and (7.5mg/kg ip, (16mg/kg ip, effect qdx5) contrasts with being used in combination Paclitaxel in effect q3dx5).
When this research carried out for three weeks, in the combined treatment group, there be significant inhibition the (very significantly effect) in tumor growth.Much obvious (Figure 28) are compared in this effect with independent use taxotere.
8. the research in mouse melanoma B16 F10 metastatic tumo(u)r model
This research has been checked the intravenous injection of B16 F10 melanoma cell was gone into mouse after 16 days, uses KPU-2, KPU-35 and tert-butyl-phenyl ahistins separately and is used in combination the effect of Paclitaxel to the metastatic tumor number of lung surface appearance.This model is not an xenograft models; Yet it does not carry out the height vascularization in described tumor mass.
In this model, the most effective methods of treatment is to use KPU-2 (Figure 29) separately, and its mean transferred knurl number lacks 10% (MGI is respectively 41.6% and 35.0%) than independent use Paclitaxel approximately.Although this research itself can not description taken in conjunction treatment more effective than single therapy, it shows that really KPU-2, KPU-35 and tert-butyl-phenyl ahistins are the most effective in the tumour of height vascularization.

KPU-02 is to the inhibition of tubulin polymerization
In external cell free system, the ability that KPU-02, CA4 and CLC is changed tubulin (MTP) polymerization (2mg/ml) of being rich in MAP is analyzed.At first, with the inhibition (data not shown) of phosphorylated cotton tubulin analysis purifying, no microtubule-associated protein to polymerization.With respect to the MAPs of tubulin copurification in the presence of the MTs that assembles, KPI-02 is to the more effective inhibitor of MTs with glycerine and DMSO assembling.Though when not having stabilization MAP and existing, the microtubule polymerization body did not reach stable state in 2 hours, these are analyzed and confirm that KPU-02 is directly with the tubulin interaction of purifying and do not bring into play its basic role by MAP.
When measuring by scattering of light (Figure 44) and sedimentation analysis (Figure 45), KPU-02 and CA4 suppress the MT polymerization more consumingly than CLC.When having the medicine of a series of concentration, MTP (2mg/ml) is polymerized to microtubule, and by the scattering of light monitoring at 350nm, it has reached stable state.Figure 41 has shown the NPI-2358 (a) at DMSO pharmaceutical carrier (◇), 1.25 μ M (), 2.5 μ M (-) and 5M (zero), under the existence of CA4 (b) and CLC (c), and the turbidity spectrum of tubulin polymerization effect.KPU-02 and CA4 suppress the MT polymerization and have suitable usefulness.Figure 45 has shown when lacking or having a series of KPU-02 (zero), CA4 () and colchicine (◇) concentration, the inhibition of microtubule polymerization.By precipitating to determine the total polymerization physique amount of assembling after 75 minutes.Error bar is the standard deviation value from three experiments.Concentration (the IC that suppresses 50% polymerization 50) be 2.4 ± 0.4 μ M to KPU-02, CA4 is that 2.2 ± 0.3 μ M and CLC are 7.6 ± 2.4 μ M (table 22).(unless refer else, the discrepancy report that obtains by statistical study is a standard deviation value).For polymerization in the body of the tubulin that is rich in MAP, be higher than IC at drug level 50The time, MTP has shown kinetics of aggregation, this shows that KPU-02 and CA4 isolate albumen to stop the microtubule assembling.

CLC 7.6±2.4 3
As shown in figure 44, three kinds of all described test agent produce the concentration dependent restraining effect of microtubule polymerization degree in the scope of 1.25-5 μ M.In described spectrum, note 2 important differences.At first, light absorption ratio initial growth rate in time reduces (Figure 44 A and 44B) with the increase of drug level.Described spectrum shows that the formation of MT exists the lag phase in the presence of KPU-02 and CA4.The medicine that also reduces the tubulin pond soluble, that the assembling ability is arranged significantly fast reduces the initial speed of polymeric.On the contrary, the initial speed of polymeric does not all have to change (Figure 44 C) in all CLC concentration.Secondly, as in time and shown in the linear light absorption value that increases, in the presence of KPU-02 or CA4, MTP does not reach stable state (Figure 44 A and 44B) when high drug level (more than the 5 μ M).On the contrary, in the presence of CLC, MTP reaches stable state (Figure 44 C) when high drug level.
By to analyzing with the linear relationship that the increase of drug level reduces, determine to suppress the needed medication amount (IC of 50% polymerization through the microtubule polymerization body of centrifugation 50) (Figure 45).The error bar of Figure 45 is represented the standard deviation value from least three independent experiments.
Measure the minimizing of average microtubule length by transmission electronic microscope technology
The described polymer that reagent-microtubule polymerization reaction carrying out transmission electronic microscope technology is formed when describing stable state is also estimated by the conclusion that draws in the light scattering spectrum.KPU-02, CA4 and CLC all reduce the microtubule length that forms when stable state.MTs shorten gradually with the increase of drug level (Figure 46,47 and 48).Figure 46 shown (A) KPU-02, (B) CA4 and (C) CLC in the presence of, the frequency histogram of external average microtubule length when stable state.Described Zeiss MOPIII is used for determining the length distribution and the mean length of microtubule.Each drug level is counted 100 microtubules at least.Figure 47 has shown that Electron Microscopy is used to write down and has not existed or the microtubule when having test compounds.In the time of 75 minutes, the sample of the physique of auto-polymerization in the future amount experiment is fixed, dyeing, and in Jeol electron microscope-1200EX11, observe with the 2000x enlargement ratio.(A) KPU-02, (b) CA4 and (C) CLC in the presence of, during stable state at the exemplary electronic microscope figure of the microtubule that is rich in MAP of external formation.The scale bar is 10 μ M.Figure 48 has shown in the presence of KPU-02, CA4 and colchicine, the graphic summary that MT length reduces when stable state.The black square is 1.25 μ M, and the shade square is the medicine of 2.5 μ M.In the presence of KPU-02 and CA4, MTs shortens gradually with the increase of drug level, is under this concentration until drug concentrations, detects MTP by turbidity and shows kinetics of aggregation, and do not observe MTs.Error bar is from the standard deviation value that at least 100 microtubules are measured.
KPU-02, CA4 and CLC do not influence the MT nucleation.Numerous, short microtubule proof KPU-02, CA4 that forms in described polyreaction and the existence of CLC do not influence nucleation.If influence nucleation,, in the sample of drug treating, observe the long microtubule opposite, less with numerous short microtubules then with respect to control sample.
Aspect minimizing MT mean length, KPU-02 and CA4 have comparable validity.When the lowest concentration of drug 1.25 μ M that analyze by Electron Microscopy, KPU-02 and CA4 have reduced the MT mean length about 70%, and CLC has reduced about 40% (Figure 48).
Microtubule polymerization for external is higher than IC at drug level 50The time, for KPU-02 and CA4, do not observe microtubule by Electron Microscopy.On the contrary, for all concentration of the CLC that is measured, observe microtubule by Electron Microscopy.Be higher than IC in concentration 50The time, in the presence of KPU-02 and CA4, tubulin has shown kinetics of aggregation, it is characterized in that light absorption ratio in time and linear increase (Figure 44 A and 44B), and in the presence of CLC, the scattering of light polymer reaches stable state (Figure 44 C).MTP increases in time at 350nm in the presence of KPU-02 or CA4 although observe, and does not observe the protein aggregate of drug specificity.
Fluorescence spectroscopy
In the time of 25 ℃, in PEM50 and 2mM GTP, tubulin (0.2mg/ml) was hatched 20 minutes with the KPU-02 of a series of concentration.KPU-02 is with the fluorescence (Figure 49 A) of concentration dependent mode quencher bis-ANS.For by the fluorescence intensity of bis-ANS when the emission maximum attitude being carried out the KPU-02 and tubulin that nonlinear regression analysis measures Kd=10 ± 1.6 μ M (standard error) (Figure 49 B).Suppose that each tubulin dimer has the single binding site to KPU-02, the dissociation constant that the double reciprocal plot of described binding data produces is 6.4 μ M (Figure 49 C).By non-linear two different K that obtain with the linear regression analysis method dValue is fully approaching, and thinks this numerical approximation equivalence.Figure 49 A has shown in the presence of ever-increasing KPU-02, the fluorescence emission spectrum of tubulin.Medicine is in conjunction with causing the bis-ANS Quenching of fluorescence.Figure 49 B has shown the fluorescent emission maximum value at 487nm, and match is to obtain the K of tubulin to KPU-02 dValue, 10 μ M, standard deviation are 1.6 μ M.Illustration is a residue.Figure 49 C has shown the conversion two reciprocal of described binding data when supposing one mole of medicine/mole tubulin dimer.
CLC bonded competitive inhibition
KPU-02 and CA4 suppress CLC competitively in conjunction with tubulin (Figure 50).Figure 50 has shown the result of inhibition analysis, wherein do not have (◇) or having 10 μ M KPU-02 (zero) or during 10 μ MCA4 (), with multiple concentration [ 3H] CLC hatches the tubulin (0.2mg/ml) of phosphorylated cotton purifying.The Km of tubulin-CLC is 11 ± 4.4 μ M, and to suppress constant be 3.2 ± 1.7 μ M for KPU-02, is 2.4 ± 0.3 μ M for CA4.Computational constant from three independent experiments.Described colchicine-tubulin association reaction is the time and temperature dependent, and this bonded dissociation constant is K d=0.1-1 μ M, this depends on the condition (Wilson L and Meza I) (1973) of described analysis.The mechanism of action of colchicine (mechanism of action of colchicine).Colchicinebinding properties of sea urchin sperm tail outer doublet tubulin (the colchicine binding characteristics of two tubulins in the sea urchin sperm tail outside) Journal of Cell Biology 58 (3): 709-19 is incorporated herein by reference in its entirety.Under test conditions, for CLC, the K of tubulin mBe 11 ± 4.4 μ M.Can think K mBe the K of tubulin substantially to CLC dValue, still, since CLC bonded time-dependent manner, K mCompare K dThe value of being reported is big.Described K iValue is 3.2 ± 1.7 μ M for KPU-02, is 2.4 ± 0.3 μ M for CA4.This K iBe defined as and suppress 50% CLC in conjunction with required medication amount, and based on the amount in conjunction with the radioactivity CLC of tubulin.This K iBe described medicine and the measurement CLC competitive capacity; It is not that medicine-tubulin is in conjunction with dissociated direct measurement, because report avidity in the described method.
The result
In all concentration of the CLC that is analyzed, the tubulin that is rich in MAP reaches stable state.On the contrary, in the KPU-02 or CA4 of higher drug concentration, the tubulin that is rich in MAP is not polymerized to stable state, and does not observe microtubule by electron microscope.KPU-02 and CA4 reduce the concentration of available tubulin effectively.This minimizing in solubility tubulin pond makes the threshold concentration of MT increase, and stops polymerization.Combine with the data that tubulin when those concentration are above does not reach stable state at required KPU-02 of external minimizing polymer quality and the chemistry amount of CA4, show that KPU-02 and CA4 work by isolation mechanism, in this isolation mechanism, the solubility tubulin is combined, stops polymerization.
By electron microscope observation, the microtubule that is rich in MAP that forms in the presence of described test agent is consistent with the mechanism that is proposed (being that KPU-02 and CA4 isolate tubulin) when described stable state.In the presence of KPU-02, CA4 and CLC, the mean length of tubulin exists concentration dependent to reduce.In the presence of KPU-02 and CA4, initial rate of polymerization exists the drug level dependency and reduces, and this shows that these medicines reduce the tubulin that can be used for prolonging.Because itself and tubulin slow fixation, so, do not see the reduction of initial rate of polymerization for CLC.In addition, for polymerization, surpass its IC in CLC concentration 50Form microtubule during value, but surpass its IC at KPU-02 or CA4 concentration 50Do not form microtubule during value.Be not bound by any particular theory, must be by the concentration of KPU-02 or CA4 bonded solubility tubulin to proceed below the required threshold concentration of tubulin polymerization.
In conjunction with studies show that with respect to CLC, tubulin has lower avidity to KPU-02.KPU-02 and CA4 took place in 20 minutes incubation period suppress CLC in conjunction with tubulin, this shows that KPU-02 and CA4 reach equilibrium ratio CLC faster (data not shown) with combining of tubulin.With described CLC-binding site eclipsed site on, KPU-02 competitive inhibition CLC is in conjunction with tubulin, this and consistent (the Kanoh K of research that characterizes phenyl A Xi Si spit of fland (halimide), Kohno S, Kataka J, Takahashi J and UnoI. (1999) (-)-Phenylahistin arrests cells inmitosis by inhibiting tubulin polymerization ((-)-phenyl A Xi Si spit of fland suppresses cell mitogen by suppressing the tubulin polymerization) The Journal of Antibiotics 52 (2): 134-141 is incorporated herein by reference in its entirety).Also competitive inhibition CLC combination of CA4 (analog of CLC).Be not subjected to the constraint of any particular theory, although it is evident that the shared tubulin land with CLC, KPU-02 and CA4 are by coming to interact with tubulin and suppress microtubule with the distinct mechanism of CLC.
