In a search for novel platelet-activating factor (PAF) antagonists, we found that 1-(3-phenylpropyl)-4-[2-(3-pyridyl)thiazolidine-4-carboyl]piperazine (3%) showed in vitro and in vivo PAF-antagonistic activities. Introduction of functional groups at the benzylic methylene carbon of 3x afforded some compounds with more potent PAF-antagonistic activity than 3x. Among them 1-(3-methyl-3-phenylbutyl)-4-[2-(3-pyridyl)thiazolidine-4-carbonyl]-piperazine fumarate (3al, YM264) was found to be one of the most potent PAF antagonists.
在寻找新型血小板激活因子(PAF)拮抗剂的过程中,我们发现1-(3-苯基丙基)-4-[2-(3-吡啶基)噻唑烷-4-羧基]哌嗪(3%)表现出体外和体内的PAF拮抗活性。在3x的苄基亚甲基碳上引入功能团,获得了一些比3x更具活性的化合物。其中,1-(3-甲基-3-苯基丁基)-4-[2-(3-吡啶基)噻唑烷-4-羧基]-哌嗪富马酸盐(3al,YM264)被发现是效果最强的PAF拮抗剂之一。
