Synthesis and structure-activity relationships of new ACAT inhibitors
摘要:
A series of heterocyclic ureas were synthesized and their ability to inhibit arterial and intestinal ACAT was assessed in animals. The structural modifications carried out in this series led to N-2-(2,4-difluorophenyl)-N-1-8-(4-fluorophenyl)-2,3,4,5-tetrahydro-1-benzoxepin-5-yl-N-1-n-heptylurea 21, which proved to be very active on both the inhibition of aortic ACAT and the inhibition of rat cholesterol intestinal absorption, thus exhibiting a strong hypocholesterolemic effect po in the rat (ED(25) = 0.2 mg/kg).
通过一川重排和闭环复分解反应合成5-氨基二氢苯并[ b ]氧杂环丁烷和5-氨基二氢苯并[ b ]氮杂环庚烷
摘要:
市川的重排和烯丙基氨基甲酸酯的闭环复分解反应的组合是作为用于制备5-氨基-取代的2,5-二氢-苯并[方法b ] oxepines,2,5-二氢-苯并[ b ] zepines和2,5-二氢-苯并[ b ]噻吩类。已经证明,使用非外消旋的烯丙基氨基甲酸酯能够合成对映体富集的苯并稠合的七元杂环。最后,显示了所获得结构的进一步功能化允许获得具有药理活性的5-氨基取代的2,3,4,5-四氢-1-苯并[ b ]奥沙平支架。
