A series of 4-substituted 1,2-diacyl-1,2,4-triazolidine-3,5-diones were synthesized and shown to be hypolipidemic in rodents; serum cholesterol and triglyceride levels were significantly reduced following intraperitoneal and oral dosing at 20 mg/kg/day. The hypolipidemic activity of the triazolidine-3,5-diones was improved when R1 was either a phenyl or a butyl group. Tissue lipid levels were reduced
合成了一系列的4-取代的1,2-二酰基-1,2,4-三唑烷-3,5-二酮,它们在啮齿动物中表现出降血脂作用。腹膜内和口服剂量为20 mg / kg /天后,血清胆固醇和甘油三酯水平显着降低。当R1为苯基或丁基时,三唑烷-3,5-二酮的降血脂活性得到改善。14天后,肝脏,主动脉和小肠中的组织脂质水平降低,而粪便脂质(例如胆固醇)升高。极低密度脂质胆固醇水平降低了,但高密度脂质胆固醇水平显着提高了。看来,1,2-二酰基-1,2,4-三唑烷-3,5-二酮的作用方式是通过抑制脂质合成的从头速率限制酶。
