inhibitory activity. Among such compounds, the 5-(2,3-dimethoxyphenyl) derivative 2t exhibited potent inhibition of cholesterol biosynthesis in HepG2 cells. As a result of optical resolution study of 2t, the absolute stereochemistry required for inhibitory activity was determined to be 3R,5S. In vivo study showed that the sodium salt of (3R,5S)-7-chloro-5-(2,3-dimethoxyphenyl)-1-neopentyl-2-oxo-1,2,3,5-tetrahydro-4
合成了一系列的(3,5-反式)-2-氧代-5-苯基-1,2,3,5-四氢-4,1-苯并x氮平衍生物,并评价了其对角鲨烯合酶的抑制作用和对胆固醇生物合成的抑制作用。通过修饰先导化合物1a和1b的取代基,发现在1位带有异丁基和新戊基,在7位具有氯原子和在氯原子上具有4,1-苯并氮杂氮杂-3-乙酸衍生物。在5-苯环的2'-位上的甲氧基具有强力的角鲨烯合酶抑制活性。在这些化合物中,5-(2,3-二甲氧基苯基)衍生物2t在HepG2细胞中显示出有效的胆固醇生物合成抑制作用。作为2t光学拆分研究的结果,抑制活性所需的绝对立体化学被确定为3R,5S。
