for their ability to inhibit acyl-CoA: cholesterol O-acyltransferase (ACAT) in vitro and to lower plasma total cholesterol in vivo. For this series of compounds, our objective was to systematically replace substituents appended to the amide and tetrazole moieties of 1 with structurally diverse functionalities and assess the effect that these changes have on biological activity. The ensuing structure-activity
制备了一系列(+/-)-2-十二烷基-α-苯基-N-(2,4,6-三甲氧基苯基)-2H-四唑-5-乙酰胺的四唑酰胺衍生物(1)并对其性能进行了评估在体外抑制酰基辅酶A:胆固醇O-酰基转移酶(ACAT),并在体内降低血浆总胆固醇。对于这一系列化合物,我们的目标是使用结构上不同的功能性系统取代取代基1的酰胺和四唑部分,并评估这些变化对生物活性的影响。随后的结构活性关系(SAR)研究确定了2,4,6-三甲氧基苯基的芳基(7b)和杂芳基(7f,g)替代物在体外有效抑制肝微粒体和巨噬细胞ACAT并表现出良好的降胆固醇活性(56-血浆总胆固醇在30 mg / kg时降低66%),相对于1,在高胆固醇血症的急性大鼠模型中进行比较。但是,用吸电子取代基(13e-h)替换α-苯基部分会显着降低肝微粒体ACAT抑制活性(IC50> 1 microM)。这与给电子的取代基(13ij,mq)相反,后者在肝微粒体测定中产生的IC50值为5至75
