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 activity and evident prolongation of prothrombin, time (PT) with the moderate bioavailability in rats. The X-ray crystal, analysis afforded an obvious binding mode that, 5-methyl-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine and 6-chloronaphthalene, respectively bound to S4 and S1 subsites. In this X-ray study, we, discovered a novel intramolecular S-O close contact. Ab initio energy, calculations of model compounds deduced that conformers with the most, close S-O proximity were most stable. The Mulliken population analysis, proposed that this energy profile was caused by both of electrostatic S-O, affinity and N-O repulsion. The results of these calculations and X-ray, analysis suggested a possibility that the restricted conformation effected, the affinity to S4 subsite of fXa.
