A variety of fused heterocyclic compounds (2-11) were synthesized as a modification of the lead compound 1a and evaluated for their inhibition of squalene synthase. 4,1-Benzothiazepine derivative 2, 1,4-benzodiazepine derivative 6, 1,3-benzodiazepine derivative 7, 1-benzazepine derivative 9, and 4,1-benzoxazocine derivative 10 potently inhibited squalene synthase activity, whereas the 4,1-benzoxazepine
合成了多种稠合的杂环化合物(2-11),作为先导化合物1a的修饰,并评估了它们对角鲨烯合酶的抑制作用。4,1-苯并噻氮平衍生物2、1,4-苯并二氮杂卓衍生物6、1,3-苯并二氮杂卓衍生物7、1-苯并ze庚因衍生物9和4,1-苯并恶唑啉衍生物10有效抑制角鲨烯合酶活性,而4,1-苯并a氮平衍生物1是最有效的抑制剂。发现4,1-苯并噻氮平S-氧化物衍生物4,1,4-苯并二氮杂卓衍生物5,1,3,4-苯并三氮杂卓衍生物8和1,2,3,4-四氢喹啉衍生物11具有弱活性。这些化合物(1a,2、4、5、7和10)的X射线结构比较表明,5-(或6)-苯基的取向对活性很重要。
