Design, synthesis, and structure–activity relationship of novel and effective apixaban derivatives as FXa inhibitors containing 1,2,4-triazole/pyrrole derivatives as P2 binding element
摘要:
Four series of novel and potent FXa inhibitors possessing the 1,2,4-triazole moiety and pyrrole moiety as P2 binding element and dihydroimidazoleitetrahydropyrimidine groups as P4 binding element were designed, synthesized, and evaluated for their anticoagulant activity in human and rabbit plasma in vitro. Most compounds showed moderate to excellent activity. Compounds 14a, 16, 18c, 26c, 35a, and 35b were further examined for their inhibition activity against human FXa in vitro and rat venous thrombosis in vivo. The most promising compound 14a, with an IC50 (FXa) value of 0.15 mu M and 99% inhibition rate, was identified for further evaluation as an FXa inhibitor. (C) 2016 Elsevier Ltd. All rights reserved.

The two-step synthesis of spirocyclic pyrazolone derivatives from simple and commercially available reagents is described. The unusual reaction of 1,3-dicarbonyls with hydrazines and an iodine-mediated oxidative carbon–nitrogen bond formation, joined in a two-step, one-pot reaction, allows the straightforward synthesis of these spirocycles.
