Factor Xa in Complex with the Inhibitor APIXABAN (BMS-562247) AKA 1-(4-METHOXYPHENYL)-7-OXO-6-(4-(2-OXO-1-PIPERIDINYL)PHENYL)-4,5,6,7-TETRAHYDRO-1H-PYRAZOLO[3, 4-C]PYRIDINE-3-CARBOXAMIDE
OverviewOverview
Efforts to identify a suitable follow-on compound to razaxaban (compound, 4) focused on modification of the carboxamido linker to eliminate, potential in vivo hydrolysis to a primary aniline. Cyclization of the, carboxamido linker to the novel bicyclic tetrahydropyrazolopyridinone, scaffold retained the potent fXa binding activity. Exceptional potency of, the series prompted an investigation of the neutral P1 moieties that, resulted in the identification of the p-methoxyphenyl P1, which retained, factor Xa binding affinity and good oral bioavailability. Further, optimization of the C-3 pyrazole position and replacement of the terminal, P4 ring with a neutral heterocycle culminated in the discovery of, 1-(4-methoxyphenyl)-7-oxo-6-(4-(2-oxopiperidin-1-yl)phenyl)-4,5,6,7-tetrah, ydro-1H-pyrazolo[3,4-c]pyridine-3-carboxamide (apixaban, compound 40)., Compound 40 exhibits a high degree of fXa potency, selectivity, and, efficacy and has an improved pharmacokinetic profile relative to 4.
