Abstract:

Novel propanoic acid derivatives are integrin receptor antagonists or inhibitors, in particular of the avb3 integrin receptor. The compounds of the invention are for instance useful for the treatment of solid tumors by inhibition of angiogenic growth of tumor vessel network, thus promoting tumor regression, inhibition of metastatic spread, thus avoiding cancer metastases, inhibition of bone resorption, thus controlling osteoporosis, inhibition of smooth muscle cells migration into neointima, thus blocking restenosis after percutaneous coronary angioplasty and the treatment of other pathological conditions mediated by cell adhesion, cell migration or angiogenesis such e.g. diabetic retinopaty, rheumatoid arthritis and inflammation.

Description:

PROPANOIC ACID DERIVATIVES AS INTEGRIN RECEPTOR ANTAGONISTS

The present invention relates to novel non-peptide compounds which bind to the integrin receptor (xvp3, to pharmaceutical compositions containing such compounds, processes for preparing such compounds, and to methods of using these compounds, alone or in combination with other therapeutic agents. Integrins are membrane-bound receptors that mediate cell-matrix and cell-cell adhesion interactions. The compounds of present invention are useful for the treatment of diseases in which the pathology arises from ligation of an integrin receptor, especially the vitronectin receptor, and therefore of diseases mediated by cell adhesion and angiogenesis. The compounds of present invention are useful in selectively inhibiting or antagonizing ocvß3 integrin and therefore are useful for the treatment of solid tumors by inhibition of angiogenic growth of tumor vessel network, thus promoting tumor regression, inhibition of metastatic spread, thus avoiding cancer metastases, inhibition of bone resorption, thus controlling osteoporosis, inhibition of smooth muscle cells migration into neointima, thus blocking restenosis after percutaneous coronary angioplasty and the treatment of other pathological conditions mediated by cell adhesion, cell migration or angiogenesis such e. g. diabetic retinopaty, rheumatoid arthritis and inflammation.

Pharmacol The compounds of the invention are selective integrin receptor inhibitors or antagonists, in particular of the ocvß3 integrin receptors. The specific inhibiting or antagonist activity of the compounds of the invention is shown for instance by the fact that they are active in in vitro solid phase av (33-vitronectin binding assay, as described

below. av (33-vitronectin binding assay A solid phase assay for the study of ocvp3-vitronectin binding was set up on the basis of already published methods (Wong et al, Molecular Pharmacology 50: 529-537, 1996; Brooks et al., Cell 85: 683-693,1996). The human av (33 integrin was diluted into coating buffer (CB) containing 150 mM NaCI, 1 mM CaClz, 1 mM MgClz, 1 mM MnCl2, 20 mM TRIS, pH 7.4 at a concentration of 1.5 Fg/ml. Into 96-well plates, 50 u. I of the diluted integrin were added and allowed to bind to the plate walls overnight at 4°C. Next day, the assay plates were emptied and 100 gel of blocking buffer (CB buffer with 3% BSA) were added to each well for 45 min at 37°C. After the incubation, the plates were washed three times with 100 p, I assay buffer (AB, CB buffer with 0.1% BSA); serial 1 : 1 dilution (25 tl/well) of the test compounds were added to the plates, starting from 10 mM solutions in 100% DMSO diluted to 100 uM in AB. The binding reaction was started by addition (25 ul/well) of 10 nM biotinylated vitronectin (final concentration: 5 nM), and lasted 30 min at 37°C. The concentration range of the tested compounds spanned from 50 to 0.0005 uM. At the end of the co-incubation, the assay plates were washed as before and 70 u. I of a 1: 1000 AB dilution of peroxydase- conjugated streptavidin were added per well and were allowed to react for 45 min at 37°C. Then, the plates were washed as described and 50 u, l of ready to use Turbo-TMB substrate for peroxydase were added to each well. After 30 minutes incubation at room temperature, the color development was stopped with 50 Ill sulphuric acid 0. 38 M and the plates were read at a wavelength of 450 nm with a Packard plate reader. The values obtained were analyzed by four parameters curve fit in the computer program GraphPad Prism, after normalization by a maximum binding control (Bmax) detected in wells where no competitor was added, and a minimum binding control (NSB) detected in wells where no integrin was coated. Under standard assay conditions, A450 was never under 1.0 for Bmax, and around 0.15 for NSB. The computerized algorithm gave the concentration of compound needed to inhibit the maximum binding by 50% (ICso value): for those compounds that did not inhibit this binding by 50% at the highest concentration tested, ICso value was reported as being greater then the highest concentration tested. As a positive control, increasing doses of a peptide containing the

RGD sequence was added to each plate: IC$o value of this molecule was 120 nM.

Materials Human vitronectin receptor ((xvß3) was purified from human placenta (Pytela et al, Methods in Enzymology, 144: 475-489, 1987). Turbo-TMB was from PIERCE (34022). BSA (A4503), Vitronectin (V8379), RGD peptide (G4144) and all generic reagents were from SIGMA. Vitronectin was biotinylated according to the procedure indicated in the NHS biotinylation kit from PIERCE (21420). Horseradish peroxydase- streptavidin was from Amersham (RPN1231). 96-well plates were from Costar (# 3690, EIA/RIA plate, 1/2 area flat bottom, high binding). ctIIb3-Elbrinogen binding assay A solid phase assay for the study of ocIIbß3-fibrinogen binding was set up on according to the method described for (xvps. (xllbp3 integrin was diluted into coating buffer (CB) containing 150 mM NaCl, 1 mM CaCl2, 1 mM MgC12, 1 mM MnCl2, 20 mM TRIS, pH 7.4 at a concentration of 3, ug/ml. Into 96-well plates, 50 ul of the diluted integrin were added and allowed to bind to the plate walls overnight at 4°C.

Next day, the assay plates were emptied and 100 psi of blocking buffer (CB buffer with 3% BSA) were added to each well for 45 min at 37°C. After the incubation, the plates were washed three times with 100 Rl assay buffer (AB, CB buffer with 0.1% BSA); serial 1: 1 dilution (25 µl/well of the test compounds were added to the plates, starting from 10 mM solutions in 100% DMSO diluted to 100 juM in AB. The binding reaction was started by addition (25 RI/well) of 20 nM biotinylated fibrinogen (final concentration: 10 nM), and lasted 30 min at 37°C. The concentration range of the tested compounds spanned from 50 to 0.0005 uM. At the end of the co-incubation, the assay plates were washed as before and 70 µl of a 1: 1000 AB dilution of peroxydase- conjugated streptavidin were added per well and were allowed to react for 45 min at 37°C. Then, the plates were washed as described and 50 u. l of ready to use Turbo-TMB substrate for peroxydase were added to each well. After 30 minutes incubation at room temperature, the color development was stopped with 50 all sulphuric acid 0.38 M and the plates were read at a wavelength of 450 nm with a Packard plate reader. The values

obtained were analyzed by four parameters curve fit with the computer program GraphPad Prism, after normalization by a maximum binding control (Bmax) detected in wells where no competitor was added, and a minimum binding control (NSB) detected in wells where no integrin was coated. Under standard assay conditions, A4so was never under 0.8 for Bmax, and around 0.15 for NSB. The computerized algorithm gave the concentration of compound needed to inhibit the maximum binding by 50% (IC50 value): for those compounds that did not inhibit this binding by 50% at the highest concentration tested, ICso value was reported as being greater then the highest concentration tested. As a positive control, increasing doses of a peptide containing the RGD sequence was added to each plate: ICso value of this molecule was 2.3 tM for (xIIbß3-fibrinogen binding.

Materials Human fibrinogen receptor (ocIIbß3) was purified from human platelets ( (Pytela et al, Methods in Enzymology, 144: 475-489,1987). Turbo-TMB was from PIERCE (34022). BSA (A4503), fibrinogen (F4883), RGD peptide (G4144) and all generic reagents were from SIGMA. Fibrinogen was biotinylated according to the procedure indicated in the NHS biotinylation kit from PIERCE (21420). Horseradish peroxydase- streptavidin was from Amersham (RPN1231). 96-well plates were from Costar (&num 3690, EIA/RIA plate, 1/2 area flat bottom, high binding).

Cell Based Assay Cell Line Adhesion assay to vitronectin is performed using CEM (human leukemia cell line) stably transfected with cDNAs encoding human ccv and 3 integrin subunits. The CEM D9 clone, expressing high levels of ocv ß3 integrin as confirmed by western blotting, was selected for the assay. The binding of CEM D9 to vitronectin is completely inhibited by anti-ocvß3 monoclonal antibody LM609.

Coating plate Vitronectin (Sigma) is diluted to 10 gl/ml in DPBS (Dulbecco's phosphate buffered saline), dispensed 50 tl/well in 96 well high binding RIA/EIA plates (Costar) and allowed to coat overnight at 4 C°. For blank 50 u. I/well of heat denatured 3% BSA

solution (bovine serum albumin), is dispensed. Plates are washed once with DBPS and saturated with 200 ul/well of 3% BSA, for 2 h at 37°C. At the end of incubation, each well is washed once with DBPS.

Adhesion Assay For the assay, cells in log phase of growth are used. The cellular suspension is centrifuged at 1500 rpm for 8 min., washed with 10 ml of HBSS, resuspended in fresh complete medium and activated with 1 ng/ml PMA (Phorbol Miristate Acetate) for lh at 37°C. After incubation, cells are washed, counted, and diluted to a density of 1.6 X 106 cells/ml in adhesion medium (0, 1% heat denaturated BSA in HBSS + 1 mM MnCl2).

10 ! 11 of adhesion medium containing inhibitors at suitable concentrations are added to test wells. 90 . I/well of cell suspension is plated and incubated for 1 h at 37°C.

Following adhesion, plates are gently washed twice with 200 u, l of DPBSS and cells are fixed with 50 Fl TCA 50% (tricloroacetic acid) for 1 hour at 4 °C. Evaluation of cell adhesion is performed by staining with sulforhodamine B (1).

Parameters of Evaluation The percentage of relative adhesion (RA%) is calculated using the following formula: average of O. D. (570 nm) of treated cells-average of O. D. of blank % X 100 average of O. D. (570 nm) of control cells-average of O. D. of blank Where O. D. is the optical density of wells at 570 nm, using a EL 340 plate reader.

ICso is the dose inhibiting 50% of cell adhesion.

For example, compound 3-({4-{(3-{ [amino (imino) methyl] amino} benzoyl) amino]- phenyl} sulfanyl)-3- (3-pyridinyl) propanoic acid (company code PNU 277362F), when tested in avß3-vitronectin and alIb 3-fibrinogen biding assays, gave the following activity data: αvß3 (IC50 µmol) = 0.016 + 0.009 aIIbß3 (IC50, umol) = 9.8 4.8 These test data show that compound 3-({4-[(3-{ [amino (imino) methyl] amino}- benzoyl) amino]-phenyl} sulfanyl)-3- (3-pyridinyl) propanoic acid is endowed with high
