Novel indoline-based acyl-CoA: cholesterol acyltransferase inhibitor: Effects of introducing a methanesulfonamide group on physicochemical properties and biological activities
A novel series of indoline-based acyl-CoA: cholesterol acyltransferase (ACAT) inhibitors with a methanesulfonamide group at the 5-position were synthesized and their lipophilicity and biological activities were evaluated. Hepatic ACAT inhibitory and anti-foam cell formation activity increased dependent on lipophilicity of derivatives with various alkyl chains at the 1-position. The log D7.0–biological
合成了一系列新的基于吲哚啉的酰基辅酶A:胆固醇酰基转移酶(ACAT)抑制剂,该抑制剂在5位带有甲磺酰胺基,并评估了它们的亲脂性和生物学活性。肝ACAT抑制和消泡细胞形成活性的增加取决于1位具有各种烷基链的衍生物的亲脂性。日志 d 7.0的衍生物与甲磺酰胺基-生物活性曲线向左移动相比,与羧甲基帕替麦布衍生物,并与无取代基的衍生物,这表明甲磺酰胺基起着与ACAT蛋白的相互作用中起重要作用。在衍生物中,N-(1-乙基-5-甲磺酰基氨基-4,6-二甲基吲哚-7-基)-2,2-二甲基丙酰胺(1b)的log D 7.0比Pactimibe低约2倍 ,而对肝脏ACAT的抑制作用则比Pactimibe高2倍。与Pactimibe相同的消泡细胞形成。所述Ç最大的1b中(10毫克/千克,口服)比在大鼠中帕替麦布的更高。1b的血浆蛋白结合率分别低于Pactimibe:64.8%和97.9%。化合物1b与Pact
