A series of heterocyclic amides were synthesized and evaluated as inhibitors of acyl-CoA: cholesterol O-acyltransferase (ACAT) in vitro and for cholesterol lowering in cholesterol-fed rats. Compounds were evaluated for cell-based macrophage ACAT inhibition, bioactivity, and adrenal toxicity. Candidates were selected for evaluation in cholesterol-fed dogs and, ultimately, the injured cholesterol-fed
合成了一系列杂环酰胺,并将其作为酰基辅酶A抑制剂:胆固醇O-酰基转移酶(ACAT)的体外抑制剂,以及在胆固醇喂养的大鼠中降低胆固醇的方法进行了评估。评价化合物对基于细胞的巨噬细胞ACAT的抑制作用,生物活性和肾上腺毒性。选择候选对象进行胆固醇喂养的狗的评估,并最终评估受伤的胆固醇喂养的兔动脉粥样硬化模型。在急性胆固醇喂养的大鼠模型中,杂环酰胺有效抑制兔肝脏ACAT(IC50 = 0.014-0.11 microM),大多数化合物以3 mg / kg的浓度显着降低血浆胆固醇(42-68%)。在基于细胞的巨噬细胞ACAT分析中评估了大鼠中最有效的化合物的体内生物活性和动脉ACAT抑制作用。两种具有高生物活性的类似物,(+/-)-2-(3-十二烷基异恶唑-5-基)-2-苯基-N-(2,4,6-三甲氧基苯基l)乙酰胺(13a)和(+/-)-2-(5-选择十二烷基异恶唑-3-基)-2-苯基-N-(2
