Disclosed herein are substituted vinylurea derivatives represented by the following general formula (1):
wherein R1 and R3 are independently a phenyl group which may be substituted, R2 is a phenyl group which may be substituted, or a cycloalkyl group, and wave lines mean that the bonding state may be either E or Z, with the proviso that the cases where R1, R2 and R3 are unsubstituted phenyl groups, and where R1 and R2 are unsubstituted phenyl groups and R3 is a 4-ethoxyphenyl group are excluded, or salt thereof, and medicines comprising such a derivative as an active ingredient as well as a method of preventing and treating arteriosclerosis with such a medicine. The derivatives or salts thereof selectively and strongly inhibit ACAT in macrophages and are hence useful as prophylactic and therapeutic agents for arteriosclerosis.
本文公开了由以下通式(1)代表的取代的乙烯基脲衍生物:
其中 R1 和 R3 独立地为可被取代的苯基,R2 为可被取代的苯基或环烷基,波浪线表示键合状态可以是 E 或 Z,但 R1、R2 和 R3 为未被取代的苯基的情况除外、以及 R1 和 R2 为未取代苯基且 R3 为 4-乙氧基苯基的情况除外。这些衍生物或其盐可选择性地强烈抑制巨噬细胞中的 ACAT,因此可用作动脉硬化的预防和治疗药物。
