N-[4-[(2-amino-3-chloro-4-pyridinyl)oxy]-3-fluorophenyl]-4-ethoxy-1-(4-fluorophenyl)-1,2-dihydro-2-oxo-3-pyridinecarboxamide is a selective and orally efficacious Inhibitor of the Met Kinase superfami ly.

ChEBI: N-[4-[(2-amino-3-chloro-4-pyridinyl)oxy]-3-fluorophenyl]-4-ethoxy-1-(4-fluorophenyl)-2-oxo-3-pyridinecarboxamide is an aromatic amide.

bms 777607 is a novel, selective and orally available atp-competitive met kinase inhibitor that primarily targets several met family members, including ron, met, tyro-3 and axi, with half maximal inhibitory concentration ic50 of 1.8 nmol/l, 3.9 nmol/l, 4.3 nmol/l and 1.1 nmol/l respectively. moreover, at higher concentrations, bms 777607 has been found to inhibit other protein tyrosine kinases, including mer, flt-3, aurora b, lck and vegfr2 with ic50 of 14 nmol/l, 16 nmol/l, 78 nmol/l, 120 nmol/l and 180 nmol/l respectively. in previous studies, bms 777607 potently inhibited the auto-phosphorylation of c-met (ic50: 20 nmol/l) leading to impaired xenograft growth.small-molecule inhibitor bms-777607 induces breast cancer cell polyploidy with increased resistance to cytotoxic chemotherapy agents. mol cancer ther. 2013 may;12(5):725-36. doi: 10.1158/1535-7163.mct-12-1079. epub 2013 mar 6.

3-Chloro-4-(4-(4-ethoxy-1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxamido)-2-fluorophenoxy)pyridin-2-amine (1.2 g, 2.1 mmol) was used as a starting material and was dissolved in a solvent mixture of ethyl acetate (16 mL), acetonitrile (16 mL) and water (8 mL) at 0 °C. Subsequently, iodophenyl diacetate (820 mg, 2.6 mmol, Aldrich) was added. The reaction mixture was stirred at room temperature for 2 h before the crude product was collected by filtration. The solid was washed with additional ethyl acetate. The filtrate was washed with saturated aqueous sodium bicarbonate and the organic phase was dried with anhydrous sodium sulfate and subsequently concentrated under vacuum. The precipitate was combined with the concentrated filtrate and purified by rapid chromatography on silica gel (eluent: 2% methanol/chloroform) to afford the target compound, N-(4-((2-amino-3-chloropyridin-4-yl)oxy)-3-fluorophenyl)-4-ethoxy-1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxamide (810 mg, yield 74%). It was a white solid. The product was characterized by 1H NMR (DMSO-d6) and MS (ESI+): 1H NMR (DMSO-d6) δ 10.57 (s, 1H), 7.83-7.79 (m, 2H), 7.67 (d, 1H, J = 5.6Hz), 7.41-7.38 (m, 3H), 7.36-7.22 (m, 3H), 6.44 (d, 1H, J = 5.6Hz). 1H, J = 7.6 Hz), 6.36 (br s, 2H), 5.86 (d, 1H, J = 6.0 Hz), 4.18 (q, 2H, J = 7.2 Hz), 1.23 (t, 3H, J = 7.2 Hz); MS (ESI +) m/z 513.09 (M + H)+.
