Description

IP5 Substituted Compounds

Technical field

[1] The present invention relates to IP5 substituted compounds, their processes of synthesis, and their uses.

State of the art

[2] Crystallization and deposition of calcium salts are common phenomena. Generally, these processes are physiologically necessary for the well-being of the individual. However, on occasions, they may become abnormal and/or pathological causing a wide variety of diseases and disorders affecting the vascular and renal systems, often with devastating consequences (Khan S, et al., Pathological crystallization of calcium oxalate and calcium phosphate, in Hydroxyapatite and Related Materials, 1^st Ed., Brown P, et al., Eds. (CRC Press, Boca Raton, FL, US, 1994, Ch. 5). Hydroxyapatite (HAP), a calcium phosphate of formula Caio(P04)6(OH)2, has been identified as an agent involved in pathological crystallization (Grases F, et al., Cir J 2007; 71:1152-1156).

[3] Several crystallization inhibitors that may affect HAP formation and growth, such as pyrophosphate, bisphosphonates (e.g., etidronate, alendronate, ibandronate), and phytate, have been described previously in the art (Lomashvili K, et al., J Am Soc Nephrol 2004; 15:1392-1401, Bevilacqua M, et al., Lupus 2005; 14:773-779, Price P, et al., Arterioscler Thromb Vase Biol 2001; 21:817-824, Price P, et al., J Nutr 2001; 131:2910- 2915, Grases F, et al., Front Biosci 2006; 11:136-142). More recently, a number of phytate-related compounds, such as pentaphosphate myo-inositol (IP5) substituted derivatives, have been proposed for various applications including the inhibition of HAP and/or the prevention and treatment of pathological crystallization, among others. For instance, WO2011064559 and Wang H, et al., Chem Biol 2014; 21:689-699 reveal the use of IP5 derivatives for the treatment of cancer. W02009061393 and Huang X, et al., ACS Appl Mater Interfaces 2017; 9:10435-10445 describes the use of IP5 derivatives as biological tools and calcium chelators, respectively. In addition, WO2021219135, W02017098047, and W02020058321 describe the use of these compounds for the treatment of pathologies associated with calcium. However, there is still a need in the art for new IP5 substituted derivatives that could be effective in inhibiting HAP formation and growth and/or pathological crystallization.

[27] In order that the present invention can be more readily understood, certain terms are first defined below. As used in this application, except as otherwise expressly provided herein, each of the following terms shall have the meaning set forth below. Additional definitions are set forth throughout the application.

I. Definitions

[28] The invention includes aspects in which exactly one member of the group is present in, employed in, or otherwise relevant to a given product or process. The invention includes aspects in which more than one, or all of the group members are present in, employed in, or otherwise relevant to a given product or process.

[29] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention is related. For example, the Concise Dictionary of Biomedicine and Molecular Biology, Juo, Pei-Show, 2^nd Ed., 2002, CRC Press; The Dictionary of Cell and Molecular Biology, 3^rd Ed., 1999, Academic Press; and the Oxford Dictionary of Biochemistry and Molecular Biology, Revised, 2000, Oxford University Press, provide one of skill with a general dictionary of many of the terms used in this invention. [30] Units, prefixes, and symbols are denoted in their Systeme International d'Unites (SI) accepted form. Numeric ranges are inclusive of the numbers defining the range. Where a range of values is recited, it is to be understood that each intervening integer value, and each fraction thereof, between the recited upper and lower limits of that range is also specifically disclosed, along with each subrange between such values. The upper and lower limits of any range can independently be included in or excluded from the range, and each range where either, neither or both limits are included is also encompassed within the invention.

[31] Where a value is explicitly recited, it is to be understood that values which are about the same quantity or amount as the recited value are also within the scope of the invention. Where a combination is disclosed, each subcombination of the elements of that combination is also specifically disclosed and is within the scope of the invention. Conversely, where different elements or groups of elements are individually disclosed, combinations thereof are also disclosed. Where any element of an invention is disclosed as having a plurality of alternatives, examples of that invention in which each alternative is excluded singly or in any combination with the other alternatives are also hereby disclosed; more than one element of an invention can have such exclusions, and all combinations of elements having such exclusions are hereby disclosed.

[32] About'. The term "about" as used herein to a value or composition that is within an acceptable error range for the particular value or composition as determined by one of ordinary skill in the art, which will depend in part on how the value or composition is measured or determined, i.e., the limitations of the measurement system. For example, "about" can mean within 1 or more than 1 standard deviation per the practice in the art. Alternatively, "about" can mean a range of up to 20%. Furthermore, particularly with respect to biological systems or processes, the terms can mean up to an order of magnitude or up to 5-fold of a value.

[33] When particular values or compositions are provided in the application and claims, unless otherwise stated, the meaning of "about" should be assumed to be within an acceptable error range for that particular value or composition. When the term "about" is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below the numerical values set forth. Thus, "about 10-20" means "about 10 to about 20." In general, the term "about" can modify a numerical value above and below the stated value by a variance of, e.g., 10 percent, up or down (higher or lower). [34] And/or: "And/or" where used herein is to be taken as specific invention of each of the two specified features or components with or without the other. Thus, the term "and/or" as used in a phrase such as "A and/or B" herein is intended to include "A and B," "A or B," "A" (alone), and "B" (alone). Likewise, the term "and/or" as used in a phrase such as "A, B, and/or C" is intended to encompass each of the following aspects: A, B, and C; A, B, or C; A or C; A or B; B or C; A and C; A and B; B and C; A (alone); B (alone); and C (alone).

[35] Approximately: As used herein, the term "approximately," as applied to one or more values of interest, refers to a value that is similar to a stated reference value. In certain aspects, the term "approximately" refers to a range of values that fall within 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1% or less in either direction (greater than or less than) of the stated reference value unless otherwise stated or otherwise evident from the context (except where such number would exceed 100% of a possible value).

[36] Bolus administration: As used herein, the terms "bolus administration" and "bolus injection" refer a fast intravenous injection lasting less than 10 seconds, or an intravenous infusion lasting less than 3 minutes.

[37] Comprising: It is understood that wherever aspects are described herein with the language "comprising," otherwise analogous aspects described in terms of "consisting of" and/or "consisting essentially of" are also provided.

[38] Compound: As used herein, the term "compound," is meant to include any and all free bases, isomers, and isotopes of the structure depicted. As used herein, the term "isomer" means any geometric isomer, tautomer, zwitterion, stereoisomer, enantiomer, or diastereomer of a compound. Compounds can include one or more chiral centers and/or double bonds and can thus exist as stereoisomers, such as double-bond isomers (i.e., geometric E/Z isomers) or diastereomers (e.g., enantiomers (i.e., (+) or (-)) or cis/trans isomers). The present invention encompasses any and all isomers of the compounds described herein, including stereomerically pure forms (e.g., geometrically pure, enantiomerically pure, or diastereomerically pure) and enantiomeric and stereoisomeric mixtures (e.g., racemates). Enantiomeric and stereomeric mixtures of compounds and means of resolving them into their component enantiomers or stereoisomers are well- known. A compound, salt, or complex of the present invention can be prepared in combination with solvent or water molecules to form solvates and hydrates by routine methods. In some aspects, the term compound is used to refer to an IP5 substituted compound of the present invention.

[39] Effective amount: As used herein, the term "effective amount" of a therapeutic agent, in reference to (i) an IP5 substituted compound of the present invention, (ii) any dosage form, pharmaceutical composition, or formulation disclosed herein comprising at least one IP5 substituted compound of the present invention, or (iii) a combination of an IP5 substituted compound of the present invention with one or more additional therapeutic agents), is that amount sufficient to effect beneficial or desired results. In some aspects, the beneficial or desired results are, for example, clinical results, and, as such, an "effective amount" depends upon the context in which it is being applied. The term "effective amount" can be used interchangeably with "effective dose," "therapeutically effective amount," or "therapeutically effective dose."

[40] The term effective amount relates to the specific use of an IP5 substituted compound. For example, when an IP5 substituted compound is used to inhibit the formation or growth of a calcium salt/crystal (e.g., a calcium phosphate, HAP), an effective amount would be an amount of the IP5 substituted compound capable of achieving the desired effect (e.g., the reduction of HAP crystallization/formation in blood serum or plasma).

[100] Scheme 1 : In general, the IP5 substituted compounds of the present invention (i.e., Compounds I_A) can be obtained by deprotecting the intermediates of formula IV_A (Scheme 1). The "protective group" or GP, can be, without limitation, benzyl, levulinylbenzyl, tert-butyl, o,o ’-xylenyl (by union of 2 PG in the same phosphate), 9- fluorenylmethyl, cyanoethyl and other suitable protective groups in each case. Intermediates of formula IV_A may be achieved by phosphorylation of an intermediate of formula III_A according to procedures described in the literature such as reaction with a phosphoroamidite derivative and subsequent oxidation. At the same time, intermediates of formula III_A can be obtained by hydrolysis in acid media of intermediates of formula II_A. Finally, intermediates of formula II_A may be obtained by alkylation of intermediate (2) with an alkylating agent. Preparation of (2) was previously described in the literature (Martin S, et al., J Org Chem 1994; 59(17): 4805-4820, Kardivel M, Org Biomol Chem 2008; 6(11): 1966-1972). The "leaving Group" or LG, may be, without limitation, chloride, bromide, iodide, toluenesulfonyl (Ts) or methylsulfonyl (Ms). See Fig. 5.

[101] Scheme 2 : As an alternative to Scheme 1, when R₄ or Re contain a substituted 1,2,3-triazole, compounds of formula I_A can be obtained by following the alternative route described in Scheme 2. In this way, intermediates of formula III_A can be obtained via a click reaction by using as starting materials an intermediate of formula VI_A and an alkynyl “click agent”. Intermediates VI_A can be achieved by alkylation and hydrolysis of intermediate 2 with an appropriate reagent. As another alternative, when R₄ or Re contain a terminal amine group, compounds of formula I_A can be obtained by phosphorylation of compound VI_A in order to obtain compounds VII- A, and by the subsequent deprotection/reduction of such compounds. See Fig. 6.

[102] Scheme 3: Compounds I_B may be obtained using a similar synthetic route used for compounds I_A. Thus, compounds I_B may be obtained by deprotecting intermediates of formula IV_B (Scheme 3). Intermediates of formula IV_B may be attained by phosphorylating an intermediate of formula III_B. At the same time, intermediates of formula III_B can be obtained by the hydrolysis in acid media of intermediates of formula II_B or VIII_B. Intermediates of formula VIII_B, may be achieved by the debenzylation of intermediates II_B’. Finally, intermediates of formula II_B or B’ may be obtained by the alkylation of intermediates (3) or (4), respectively, with an alkylating agent.

As an alternative, when R2 contain a substituted 1,2,3- triazole, compounds of formula I_B can be obtained by following an alternative route. In this way, intermediates of formula III_B can be also obtained via a click reaction by using as starting materials alkynyl intermediate of formula III_B and an azide “click agent”. See Fig. 7A.

Intermediates of formula IV_C may be achieved phosphorylating intermediates of formula IV_C. Intermediates of formula III_C can be obtained by the debenzylation of intermediates II_C. Finally, intermediates of formula II_C may be obtained by the alkylation of intermediate (33) with an appropriate alkylating agent. Preparation of (33) has been previously described in the art (Phenix C. et al., ChemBioChem 2008; 9(10): 1591-1602). See Fig. 8A.

[104] Scheme 5: Compounds I_D may be obtained by the deprotection of intermediates of formula IV_D (Scheme 5). Intermediates of formula IV_D may be achieved by phosphorylating intermediates of formula III_D. Intermediates of formula III_D can be obtained by the debenzylation of intermediates IX_D. Intermediates IX-D can be obtained by the hydrolysis of intermediates II_D. Finally, intermediates of formula II_D may be obtained by the alkylation of intermediate (34) with an appropriate alkylating agent. Preparation of racemate (34) has been in the art (Chen, 2015, supra). As an alternative, when R2 contain a substituted 1,2,3-triazole, compounds of formula I_D can be obtained by following the alternative route. In this way, intermediates of formula IX_D can be also obtained via a click reaction by using as starting materials alkynyl intermediate of formula IX_D and an azide “click agent”. See Fig. 9A.

[105] Scheme 6 : As an alternative to Scheme 3, when R2 contain a substituted 1,2,3- triazole or an acylamine, compounds of formula I_B can be obtained by following the alternative route described in Scheme 6. In this way, intermediates of formula III_B can be also obtained via a click reaction by using as starting materials an azide intermediate of formula V_B and an alkynyl “click agent”. Intermediate V_B can be achieved by alkylation of intermediate 3 with an appropriate reagent. As another alternative, when R2 contains a terminal acylamine group, compounds of formula III_B can be obtained by amidation of the corresponding amino compound III_B. See Fig. 7B.

[106] Scheme 7 : As an alternative to Scheme 4, when R₅ contain a substituted 1,2,3- triazole, compounds of formula I_C can be obtained by following the alternative route described in Scheme 7. In this way, intermediates of formula II_C can be also obtained via a click reaction by using as starting materials an azide intermediate of formula V_C and an alkynyl “click agent”. Intermediate V_C can be achieved by alkylation of intermediate 33 with an appropriate reagent. See Fig. 8B.

[107] Scheme s : As an alternative to Scheme 5, when Ri or R₃ contain a substituted 1,2,3-triazole, compounds of formula I_D can be obtained by following the alternative route described in Scheme 8. In this way, intermediates of formula IX_D can be also obtained via a click reaction by using as starting materials an alkinyl intermediate (where X is a triple bond) of formula V_C and an azide “click agent”. Intermediate V_C (where X is a triple bond) can be achieved by alkylation of intermediate 34 and subsequent hydrolysis of such alkenyl-protected compound II_D. As another alternative, When R₁ or R₃ contain an alkyl group, intermediates of formula with an alkyl as Rl, can be obtained via debenzilation of intermediate IX_D where X correspond to a triple bond. See Fig. 9A.

Pharmacological assays

A. In vitro inhibition of calcium phosphate crystallization

[426] The in vitro efficacy of the IP5 substituted compounds (e.g., Compounds 1 to 32) of the invention on the inhibition of calcium phosphate crystallization in human plasma samples was evaluated according to a spectrophotometric assay previously described in the art (Ferrer M, et al., Sci Rep 2017; 7:6858, doi:10.1038/s41598-017-07203-x).

[427] A 96- well plate was employed. Plasma was spiked (1 volume of the IP5 substituted compounds of the invention per 19 volumes of plasma) with increasing concentrations of the derivatives in the range of 0 - 100 pM. Plasma was then centrifuged at 10,000 g at rt and subsequently mixed with a mixture of 5 mM hydrogen phosphate and 41.67 mM calcium to attain final concentrations of 1.5 mM phosphate and 12.5 mM calcium, respectively. All reagent solutions were filtered, and pH adjusted to 7.4.

[428] Crystallization of calcium phosphate was monitored spectrophotometric ally for 30 min at rt by measuring the increments in absorbance at 550 nm using the Biotek Powerwave XS Microplate spectrophotometer (BioTek Instruments, Inc., Winooski, VT, US). The plate was incubated at rt in an orbital shaker and absorbance measured every 3 min. [429] Plasma crystallization was assessed based on slope measurement in the linear range between 6 and 24 min from plots of increase in absorbance versus logarithm of time. The efficacy of different myo-inositol phosphates derivatives in preventing in vitro formation of calcium phosphate crystals was assessed in human plasma samples using the slopes obtained between 6- and 24-min. Inhibition of crystallization was measured by comparing the slopes of the control sample (blank plasma) with those of samples containing the inhibitor as shown below:
