The present invention relates to a 5-amidino-N-(2-aminophenethyl)-2-hydroxybenzenesulfonamide derivative represented by the general formula:
wherein
R
1
is a hydrogen atom or a lower alkyl group;
R
2
represents a hydrogen atom, an optionally substituted lower alkyl group, etc.;
R
3
is a di(lower alkyl)amino group, a lower alkyl group, a cycloalkyl group, etc.; Q is a hydrogen atom or an optionally substituted lower alkyl group; and Z is a hydrogen atom or a hydroxy group, etc., or a pharmaceutically acceptable salt thereof, which exerts a potent and selective activated blood coagulation factor X inhibitory activity and is useful as an agent for the prevention or treatment of a disease occurred associating an activated blood coagulation factor X, a pharmaceutical composition comprising the same, a pharmaceutical use thereof and an intermediate thereof.
A series of novel and potent 3-amidinophenylsulfonamide derivatives of factor Xa inhibitors were designed and synthesized using an amidoxime prodrug strategy. We focused on systemic clearance of parent compounds in rats, and performed in vivo pharmacokinetic screening. Incorporation of a carboxymethoxy group markedly improved systemic clearance (compound 43), and the related amidoxime 44 showed sufficient prodrug conversion. Compound 45, the double prodrug of 43, exhibited practicable bioavailability after oral administration in rats. Among the various compounds under investigation, KFA-1982 was selected for clinical development. (C) 2008 Elsevier Ltd. All rights reserved.
