摘要

A series of benzoic acid derivatives was synthesized as VLA-4 antagonists. Introduction of chlorine or bromine into the 3-position on the central benzene of the diphenylurea portion as in lead compound 2 led to improvement in the pharmacokinetic properties. In particular, 12l demonstrated an acceptable plasma clearance and bioavailability in mice and rats as well as dogs (mice, CL= 18.5 ml/min/kg, F= 28%; rats, CL= 5.2 ml/min/kg, F= 36%; dogs, CL= ...
