  7-(3,4-Dimethoxy-benzyl)-2-(4-fluoro-phenyl)-4,5,6,7-tetrahydro-2H-indazole-3-carbaldehyde 在 manganese(IV) oxide 、 sodium tetrahydroborate 、 air 、 三乙基硼 、 sodium hydride 、 二异丁基氢化铝 作用下， 以 四氢呋喃 、 甲苯 、 苯 为溶剂， 反应 4.5h， 生成 (E)-(3S,5R)-7-[7-(3,4-Dimethoxy-benzyl)-2-(4-fluoro-phenyl)-4,5,6,7-tetrahydro-2H-indazol-3-yl]-3,5-dihydroxy-hept-6-enoic acid ethyl ester

  HMG-CoA reductase inhibitors: design, synthesis, and biological activity of tetrahydroindazole-substituted 3,5-dihydroxy-6-heptenoic acid sodium salts

  摘要：

  Compounds comprising a series of 7-[2-(4-fluorophenyl)-4,5,6,7-tetrahydro-2H-indazol-3-yl]-3,5-dihydroxy-6-heptenoic acid sodium salts (18) were synthesized and tested for their ability to inhibit HMG-CoA reductase in a partially purified enzyme preparation and cholesterol biosynthesis from acetate in cultured HEP-G2 cells. Changing the size of the saturated ring of the tetrahydroindazole nucleus did not improve potency, but incorporation of substituents at the 7-position resulted in up to 1700-fold improvement in inhibitory potency. Structure-activity studies revealed that the most potent compounds possess a substituted benzyl group at the 7-position, with a preference for steric bulk at the para position of the benzene ring. The most potent enzyme inhibitor (18t, IC50 = 3.0 nM) is approximately 3-fold more potent than lovastatin sodium salt (2). The most potent cholesterol biosynthesis inhibitor in HEP-G2 cells (18q, IC50 = 0.078 muM) is slightly less potent than 2 (sodium salt). Molecular modeling studies suggested that, when compared to the parent compound (18b) lacking the appropriate 7-substituent, 18t overlaps better with 2 and literature inhibitors 5 and 6 in a hydrophobic binding region adjacent to the enzyme active site.
