  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 Element

  摘要：

  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.

  Sulfonyl derivatives represented by the following general formula (I): Q1-Q2-T1-Q3-SO2-QA and drugs containing the same (wherein Q1 is an optionally substituted, saturated or unsaturated, five- or six-membered cyclic hydrocarbon group, a five- or six-membered heterocyclic group, or the like; Q2 is a single band, oxygen, sulfur, C1-C6 alkylene or the like; QA is optionally substituted arylalkenyl, heteroarylalkenyl or the like; and T1 is carbonyl or the like). These compounds have potent FXa-inhibitory effects and promptly exert satisfactory and persistent antithrombotic effects through oral administration, thus being useful as anticoagulant agents little accompanied with side effects.
