N,N-Dialkylated 4-(4-arylsulfonylpiperazine-1-carbonyl)-benzamidines and 4-((4-arylsulfonyl)-2-oxo-piperazin-1-ylmethyl)-benzamidines as potent factor Xa inhibitors
摘要:
A class of N,N-dialkylated 4-(4-arylsulfonylpiperazine-1-carbonyl)-benzamidines and 4-((4-arylsulfonyl)-2-oxo-pipeRazin-1-y1methyl)-benzamidiries has been discovered as potent factor Xa inhibitors with desirable in vitro and in vivo anticoagulant activity, but with low oral bioavailability. The 5-chloroindole and 6-chlorobenzo[b]thiophene groups are optimal as the factor Xa S1 binding elements. The strategy of incorporating a side chain on the piperazine nucleus to enhance binding affinity has been examined. (C) 2004 Elsevier Ltd. All rights reserved.
This invention is directed to oxoazaheterocycyl compounds which inhibit Factor Xa, to oxoazaheterocycyl compounds which inhibit both Factor Xa and Factor IIa, to pharmaceutical compositions comprising these compounds, to intermediates useful for preparing these compounds, to a method of directly inhibiting Factor Xa and to a method of simultaneously directly inhibiting Factor Xa and Factor IIa..
Novel piperazin-2-one containing compounds of general formulae (I) or (II), including their pharmaceutically acceptable isomers, salts, hydrates, solvates and prodrug derivative having activity against mammalian factor Xa arc described. Compositions containing such compounds are also described. The compounds and the compositions are useful in vitro or in vivo for preventing or treating conditions in mammals characterized by undesired thrombosis.
