Starting from Grundmann′s ketone a new chemotype of inhibitors of the post-squalene part of cholesterol biosynthesis was developed. Stereoselective introduction of an angular methyl group at C-3a, followed by a plethora of functionalisations at C-4 and C-5 led to cis-configured amino alcohols as a new chemotype of inhibitors of cholesterol biosynthesis. In cell-based screening systems these compounds
从格伦德曼开始'小号酮胆固醇生物合成的后角鲨烯部分的抑制剂的新化学型的开发。在C-3a处立体选择性地引入有角甲基,然后在C-4和C-5处进行过多的官能化,导致顺式构型的氨基醇成为胆固醇生物合成抑制剂的新化学型。在基于细胞的筛选系统中,这些化合物被鉴定为人类Δ8,7-固醇异构酶的选择性抑制剂,以低纳摩尔范围的IC 50值抑制总胆固醇的生物合成。活性最高的化合物不影响真菌Δ8,7-固醇异构酶(在麦角固醇的生物合成中),也没有显示出显着的抗微生物和细胞毒性作用。
