series of diaryl-substituted heterocyclic ureas was prepared, and their ability to inhibit acyl-CoA: cholesterol O-acyltransferase (ACAT) in vitro and to lower plasma total cholesterol in cholesterol-fed animal models in vivo was examined. N-(2,6-Diisopropylphenyl)-N'-tetrazole or isoxazole-substituted heterocyclic ureas proved optimal. A carbon chain of 11-14 carbons substituted 1,3 with respect to the
制备了一系列的二芳基取代的杂环脲,并研究了它们在体外抑制酰基辅酶A:胆固醇O-酰基转移酶(ACAT)以及在体内降低由胆固醇喂养的动物模型中血浆总胆固醇的能力。N-(2,6-二异丙基苯基)-N'-四唑或异恶唑取代的杂环脲被证明是最佳的。相对于胺而言,具有11-14个碳原子取代的1,3的碳链提供了最佳的侧链。烷基链的取代通常会降低活性。在急性胆固醇喂养(C喂养)高胆固醇血症大鼠模型中,以3 mg / kg的剂量剂量的四唑尿素2i降低血浆总胆固醇(TC)67%,在C喂养的狗中降低47%。在预先建立的高胆固醇血症大鼠中,剂量为10 mg / kg的Tetrazole 2i还能降低TC 52%和提高HDL胆固醇113%。
