further optimize the pyrazole factor Xa inhibitors centered on masking the aryl aniline P4 moiety. Scaffold optimization resulted in the identification of a novel bicyclic pyrazolo-pyridinone scaffold which retained fXa potency. The novel bicyclic scaffold preserved all binding interactions observed with the monocyclic counterpart and importantly the carboxamido moiety was integrated within the scaffold
尝试进一步优化吡唑因子Xa抑制剂的重点是掩盖芳基苯胺P4部分。支架的优化导致鉴定了保留fXa效力的新型双环吡唑并吡啶酮支架。新型双环支架保留了与单环对应物所观察到的所有结合相互作用,重要的是将羧酰胺基部分整合到支架中,使其不易水解。这些努力导致鉴定出1- [3-氨基苯并恶唑-5'-基] -3-三氟甲基-6- [2'-(3-(R)-羟基-N-吡咯烷基)甲基-[1,1 '] -biphen-4-yl] -1,4,5,6-tetrahydropyrazolo- [3,4-c] -pyridin-7-one 6f(BMS-740808),高效能(fXa Ki = 30 pM)在体外具有快速的抑制作用(2.7x10(7)M-1 s-1),具有选择性(比其他蛋白酶高1000倍以上),
