lipid-accumulation areas in the aortic arch to 74 and 69%, respectively without reducing the plasma total cholesterol level in high fat- and cholesterol-fed F1B hamsters. Here, we demonstrate the antiatherosclerotic effect of 3h in vivo via its direct action on aortic ACAT and its powerful modulator of cholesterol level. This molecule is a potential therapeutic agent for the treatment of diseases involving ACAT-1
我们描述了我们的主动脉选择性酰基辅酶A:胆固醇O-酰基转移酶(ACAT,也缩写为SOAT)抑制剂的分子设计,其结构-活性关系(SARs)以及它们的药代动力学(PK)和药理学特征。两个弱配体-N-(2,6-二异丙基苯基)乙酰胺(50%抑制浓度[IC 50 ] = 8.6μM)和2-(甲硫基)苯并[ d ]恶唑(IC 50 = 31μM)的连接包括6支亚甲基链的连接体,得到一种高度有效分子,9-(苯并[ d ]恶唑-2-基硫基) - ñ - (2,6-二异丙基)壬酰胺(3H),其表现出高效力(IC 50 = 0.004μM)朝向主动脉ACAT。这种从头到尾的设计使将活性显着提高到2150至7750倍,并基于双重诱导的拟合机制来区分同工型选择性成为可能。在1 mg / kg和3 mg / kg的剂量下,3h显着降低了主动脉弓的脂质蓄积面积,分别降至74%和69%,而没有降低高脂和高胆固醇喂养的F
