Synthesis and conformational analysis of a non-amidine factor Xa inhibitor that incorporates 5-methyl-4, 5, 6, 7-tetrahydrothiazolo [5, 4-c] pyridine as S4 binding …
Our exploratory study was based on the concept that a non-amidine factor Xa (fXa) inhibitor is suitable for an orally available anticoagulant. We synthesized and evaluated a series of N- (6-chloronaphthalen-2-yl) sulfonylpiperazine derivatives incorporating various fused-bicyclic rings containing an aliphatic amine expected to be S4 binding element. Among this series, 5- methyl-4, 5, 6, 7-tetrahydrothiazolo [5, 4-c] pyridine type 61 displayed orally potent anti-fXa ...
