Orally efficacious thrombin inhibitors with cyanofluorophenylacetamide as the P2 motif
摘要:
2-Cyano-6-fluorophenylacetamide was explored as a novel P2 scaffold in the design of thrombin inhibitors. Optimization around this structural motif culminated in 14, which is a potent thrombin inhibitor (K-i = 1.2 nM) that exhibits robust efficacy in canine anticoagulation and thrombosis models upon oral administration.

Synthesis of 2,2-difluoro-2-arylethylamines as fluorinated analogs of octopamine and noradrenaline
Abstrtact A series of 2,2-difluoro-2-arylethylamines was synthesized as fluorinatedanalogs of octopamine and noradrenaline with the expectation of bioisosteric OH/F exchanges. The syntheses of these compounds were performed by a Suzuki–Miyaura cross-coupling reaction of 4-(bromodifluoroacetyl)morpholine with aryl boronic acids to produce the intermediate 2,2-difluoro-2-arylacetamides, followed by
