Background
The present invention relates to novel compounds and pharmaceutical compositions that inhibit binding of either SDF-1 chemokine (also known as CXCL12 chemokine) or I-TAC (also known as CXCL11) to the chemokine receptor CCXCKR 2. These compounds are useful for preventing tumor cell proliferation, tumor formation and tumor metastasis.
Chemokines belong to the superfamily of small cytokine-like proteins that induce cytoskeletal rearrangements to attach firmly to epithelial cells and to migrate directionally, and also affect cell activation and proliferation. Chemokines function in a manner consistent with cell surface proteins specifically targeting various subunits of the guide cell to specific anatomical sites.
Early research efforts by several groups have indicated a role for the chemokine receptor CXCR4 in tumor metastasis and tumor growth. Muller et al, "Involvement of ChemokineReceptiors in Breast Cancer Metastasis", Nature, 410: 50-56(2001) demonstrated that breast cancer cells employ chemokine-mediated mechanisms, such as those that regulate leukocyte trafficking during tumor metastasis. Tumor cells express a unique, non-random pattern of functionally active chemokine receptors. Signaling through CXCR4 mediates actin polymerization and lichen formation in breast cancer cells and induces chemotactic and invasive responses. In addition, organs representing the major site of breast cancer metastasis (e.g., lymph nodes, bone marrow, and lungs) are a major rich source of ligands for the CXCR4 receptor.
The metastasis of injected human breast cancer cells was successfully reduced by treatment with antibodies known to bind to CXCR4 using immunodeficient mice, Muller and colleagues. Their findings suggest that breast cancer metastasis can be reduced by treating patients with CXCR4 antagonists.
Bertolini et al, "CXCR 4Neutralization, a Novel therapeutic approach for Non-Hodgkin's Lymphoma", Cancer Research, 62: 3106-. They explain their findings suggesting that tumor volume can be reduced by treating patients with CXCR4 antagonists.
Recent studies suggest that another chemokine receptor, CCXCKR2, may also be a potential candidate in the treatment of cancer. CCXCKR2 is preferentially expressed in transformed cells over normal cells, and expression is detectable in a variety of human cancers. In vitro studies indicate that proliferation of cells expressing CCXCKR2 can be inhibited by CCXCKR2 antagonists. In vivo studies in mice indicate that CCXCKR2 antagonists inhibit tumor formation and tumor growth.
Another explanation of the reduction in tumor volume observed by Bertolini and coworkers illustrates the potential importance of CCXCKR 2. This reduction is clearly a result of antibody-mediated clearance and not a result of anti-CXCR 4 antibodies as previously believed. In antibody-mediated clearance, any antibody that recognizes a cell surface protein of a lymphocyte should have the same effect as that contributed by an anti-CXCR 4 antibody. Unfortunately, the Bertolini and coworkers studies did not determine whether the observed tumor response was due to antibody-mediated clearance or interaction with CXCR 4.
However, it is currently known that lymphoid cancer cells used by Bertolini and coworkers express both CXCR4 and CCXCKR 2. SDF-1 is the only ligand for CXCR 4. Both SDF-1 and I-TAC combine CCXCKR 2. With anti-SDF-1 antibodies, CCXCKR2 antagonists have been shown to be responsible for the reduction of tumor burden and increase survival. Since SDF-1 is the only ligand for CXCR4, one would expect that neutralization of SDF-1 with anti-SDF-1 antibodies would be equivalent to neutralization of CXCR4 with anti-CXCR 4 antibodies. However, experiments with anti-SDF-1 antibodies demonstrated only partial reduction of tumor burden and increased survival. This led to the belief that CCXCKR2 was the actual target, since sustained activity was likely the result of the interaction of the second ligand, I-TAC, with CCXCKR 2.
Until recently, the possible importance of CCXCKR2 in tumor cell proliferation, tumor growth, and tumor metastasis was unknown. Currently, by virtue of the recent facts that indicate the ability of certain CCXCKR2 antagonists to prevent the growth and spread of cancer and the expression patterns that indicate limited tissue distribution of CCXCKR2 receptors, it would be beneficial to provide compounds that are capable of specifically binding to CCXCKR2 receptors on tumor cells with potentially few side effects.

Modulators (I) may also be useful as modulators against other chemokine receptors. The chemokine family of peptides is defined on the basis of sequence homology and in the presence of conserved cysteine sequence changes.

Chemokines exhibit in vitro and in vivo functions ranging from pro-inflammatory activity to proliferation-regulating activity on a range of cell types. To date, several chemokine receptors have been described.

Method for blocking CCXCKR2 receptor
While not wishing to be bound by any particular theory, the compositions of the present invention are believed to provide a means of inhibiting the binding of SDF-1 and/or I-TAC to the CCXCKR2 receptor. SDF-1 is known to provide a target that interferes with the development or spread of cancer cells in mammals such as humans. As shown below in examples 24-26, inhibition of I-TAC binding to CCXCKR2 receptor prevented vascularized tumor formation. By contacting the above-described composition with cancer cells expressing the CCXCKR2 receptor, the otherwise initiated invasive response in the cancer cells can be reduced. Thus, the present invention also relates to a method for the prevention and/or treatment of cancer, in particular solid tumor cancer, more particularly breast cancer.
CCXCKR2 is preferentially expressed in human transformed cells as determined by radiolabeled SDF-1 binding and I-TAC displacement. Table 2 includes the data in which CCXCKR2 is expressed (CCXCKR 2)+) And wherein CCXCKR2 is not expressed (CCXCKR 2)-) Those tissue types of (a).

In one embodiment, a preferred method of inhibiting the binding of chemokines SDF-1 and/or I-TAC to the CCXCKR2 receptor comprises contacting one or more of the previously mentioned compounds with a cell expressing the CCXCKR2 receptor for a time sufficient to inhibit the binding of these chemokines to the CCXCKR2 receptor.
Methods of treating cancer
The invention also provides methods of treating cancer. A preferred method of treating cancer comprises administering to a cancer patient a therapeutically effective amount of one or more of the previously mentioned compounds (or salts thereof) for a time sufficient to treat the cancer.
For therapeutic purposes, the compositions of the present invention may be administered orally, parenterally (e.g., intramuscular, intraperitoneal, intravenous, ICV, intracisternal injection or infusion, subcutaneous injection or implant), by inhalation spray, nasal, vaginal, rectal, sublingual or topical routes of administration, and may be formulated alone or in suitable dosage units containing conventional non-toxic pharmaceutically acceptable carriers, adjuvants and vehicles appropriate for each route of administration.
In addition to primates, such as humans, various other mammals can be treated according to the methods of the present invention. For example, mammals can be treated including, but not limited to, cattle, sheep, goats, horses, dogs, cats, guinea pigs, rats or other bovine, ovine, equine, canine, feline, rodent or murine species. However, the method may also be carried out in other species such as birds (e.g. chickens).

The mixture was stirred over 5g of magnesium sulfate under nitrogen. After two days, Thin Layer Chromatography (TLC) using a 9: 1: 0.1 dichloromethane/methanol/ammonium hydroxide eluent showed no presence of starting material. The reaction mixture was filtered and the collected solid was washed with dichloromethane. The resulting organic layer was then concentrated in vacuo. To the residual mixture was added 10ml of dry methanol under nitrogen and the solution was cooled to 0 ℃. To this mixture was added 0.14g of sodium borohydride. TLC showed no starting material present after about 15 minutes. The reaction was then quenched with acetone (1ml) and the solvent was removed by distillation. The mixture was partitioned between 5ml water-chloroform and the layers were separated. The aqueous layer was then extracted 3 times with 30ml chloroform. The combined organic layers were washed with brine, dried over sodium sulfate and filtered. Concentration in vacuo afforded 0.78g of a pale yellow solid. Yield: 77 percent.

Experiment of
To demonstrate that the above-described compounds are useful modulators of SDF-1 and I-TAC chemokines, the compounds were screened in vitro to determine their ability to bind to CCXCKR2 receptor in place of SDF-1 and/or I-TAC at various concentrations. E.g., in the Determination of IC50As described in detail in values, Reagents and Cells (see below), compounds bind to CCXCKR2 receptor expressed by breast Cells in the presence of 125I-labeled chemokines. Screening methods were then used to determine the ability of the compound to bind to the CCXCKR2 receptor site at various concentrations in place of the labeled chemokine.
Compounds considered to be potent modulators are capable of replacing at least 50% of the binding of the chemokines SDF-1 or I-TAC to the CCXCKR2 receptor at concentrations at or below 1.1 micromolar (. mu.M) and more preferably at or below 300 nanomolar (nM). At present, especially preferred compounds are capable of replacing at least 50% of SDF-1 or I-TAC binding to the CCXCKR2 receptor at concentrations at or below 200 nanomolar. Illustrative compounds that meet these criteria are listed in table 1 below.
TABLE 1
IC50Determination of value
Reagents and cells.125I-labeled SDF-1 was purchased from Perkin-Elmer Life Sciences, Inc. (Boston, MA). The MCF-7 (adenocarcinoma, mammary gland) cell line was obtained from the American Type Culture Collection (Manassas, Va.) and was cultured at 37 ℃ in 5% CO2In a humidified incubator with air mixture, cultures were grown in DMEM (Mediatech, Herndon, VA) supplemented with 10% bovine serum (FBS) (HyClone Logan, UT) and bovine insulin (0.01mg/mL) (Sigma, st.
And (4) performing binding analysis. The compounds of interest were tested to determine their ability to bind to the CCXCKR2 site on MCF-7 cells. The method is carried out by using HHV8-encodedvMIP-I selectedvIgages chemoreceptors CCR5.Agonist and dantagonist profiles of viral chemokiness, J.biol.chem.1999Jul 30; 274(31): 21569-74 and Gosling J et al, Cutting edge: identification of a novel receptor that will bind a critical cell-and T cell-active chemical binding ELC, SLC, and TECK, J.Immunol.2000Mar 15; 164(6): 2851-6, using the most potent radioligand binding.
In these assays, MCF-7 cells were combined with the compound of interest and the ability of these compounds to displace radiolabeled SDF-1 was evaluated using the methods described in Dairaghi and Gosling. Target compounds were added to the plates to reach the indicated concentrations, then in the following binding medium (25mM HEPES, 140mM NaCl, 1mM CaCl)2,5mM MgCl2And 0.2% bovine serum albumin, adjusted to pH 7.1) by adding a radiolabelled chemokine: (125I SDF-1) was incubated with cells at 4 ℃ for 3 hours. All assays were then incubated at 4 ℃ for 3 hours with gentle stirring. After incubation of all binding assays, the reaction was vortexed and washed twice (25mM HEPES, 500mM NaCl, 1mM CaCl) on PEI-treated GF/B glass filters using a cell harvester (Packard)2,5mM MgCl2Adjusted to pH 7.1). Mixed scintillant (MicroScint 10, Packard) was added to the wells and the filters were counted on a Packard Topcount science counter. Data were analyzed and plotted using Prism (GraphPad Prism version 3.0a by Macintosh, GraphPad software, www.graphpad.com).
Inhibition of in vitro cell proliferation
Antagonism of CCXCKR2 expressed on breast cancer by small molecular weight compounds inhibits cell proliferation in vitro. The in vitro treated cells exhibited reduced cell growth over time compared to untreated controls.
Inhibition of cell adhesion in vitro
In vitro quiescent adhesion assays are used to model the migratory activity of leukocytes, including cell adhesion and subsequent infiltration into a given tissue. A monolayer of vascular endothelial cells was grown on the surface and cells expressing CCXCKR2 were labeled with a fluorescent dye to enable visualization. Experiments have shown that the presence of cells expressing CCXCKR2 adhering to the endothelial layer promotes adhesion of cells otherwise expressing CCXCKR2, compared to a control group in which CCXCKR2 is not expressed. In addition, the addition of CCXCKR2 modulator inhibited adhesion compared to vehicle-treated controls.
Inhibition of in vivo tumor formation
Immunodeficient mice were injected with human B-cell lymphoma cells expressing CCXCKR 2. Those mice were treated with CCXCKR2 modulators that inhibit vascularized tumor formation. In one study, only 1 of 17 mice treated with CCXCKR2 antagonist developed cystic, vascularized tumors, while 11 of 17 mice in the vehicle placebo group developed cystic, vascularized tumors.
Reduction of tumor volume in vivo
Immunodeficient mice were given injections of human breast cancer. Tumors were measured three times per week and tumor volumes were determined. Mice treated with CCXCKR2 modulators exhibit reduced tumor volume compared to vehicle control group treated mice.
Those of ordinary skill in the art of organic chemistry will recognize from the provided specification, figures and examples that modifications and variations can be made to the preferred embodiments of the present invention without departing from the scope of the invention as defined by the following claims and their equivalents.
