Novel N-(4-oxochroman-8-yl)amide derivatives 1 were synthesized and tested for their ability to inhibit rabbit small intestinal ACAT (acyl-CoA:cholesterol acyltransferase) in vitro and to lower serum total cholesterol in cholesterol-fed rats in vivo. Among the synthesized compounds, N-(7-alkoxy-4-oxochroman-8-yl)amide derivatives showed potent ACAT inhibitory activity both in vitro and in vivo. The
合成了新型N-(4-氧代苯并二氢吡喃-8-基)酰胺衍生物1并测试了它们在体外抑制兔小肠ACAT(酰基-CoA:胆固醇酰基转移酶)并降低胆固醇喂养大鼠血清总胆固醇的能力。体内。在合成的化合物中,N-(7-烷氧基-4-氧代苯并吡喃-8-基)酰胺衍生物在体外和体内均显示出有效的ACAT抑制活性。在这两种测定的基础上,讨论了这些N-(4-氧代苯并吡喃-8-基)酰胺和相关化合物的构效关系。4-苯并二氢吡喃酮第4位的羰基对于有效的ACAT抑制活性至关重要。N-(色胺基-8-基)衍生物的效力不如N-(4-氧代色烷-8-基)衍生物。4-苯并二氢吡喃酮部分第7位的烷氧基对于有效的ACAT抑制活性很重要。在N-(7-烷氧基-4-氧代苯并二氢吡喃-8-基)酰胺衍生物中,引起有效ACAT抑制活性的另一个必要因素是分子的亲脂性。高度亲脂性酰胺N-(7-甲氧基-4-氧代苯并吡喃-8-基)-2,2-二甲基十二烷酰胺(3
