Description

一种化合物及其制备方法和用途 技术领域
本发明涉及一种化合物及其制备方法, 特别涉及具有
HMG-CoA还原酶抑制活性作用的化合物及其制备方法。
背景技术
内源性胆固醇在肝脏合成,由乙酸经 26步生物合成步骤在肝 细胞的细胞质中完成, 其中 3-羟基 -3-甲基戊二酰辅酶 A
( HMG-CoA )还原酶是该合成过程中的限速酶, 为内源性胆固醇合 成中的关键一步, HMG-CoA还原酶抑制剂通过抑制 HMG-CoA还原 酶的活性来减少内源性的胆固醇, 达到调血脂的效果。
目前, 常用的 HMG- CoA还原酶抑制剂有洛伐他汀、普伐他汀、 辛伐他汀、 氟伐他汀等他汀类药物。 洛伐他汀 (Lovas tat in )是 从红曲霉菌培养液中提取的霉菌代谢产物。 口服后被水解, 内酯 环打开, 变成有活性的羟基酸, 是第一个应用于临床的有效的 HMG-CoA还原酶抑制剂。 口服后, 30%被吸收并代谢为有活性的开 环羟基酸, 2 ~ 4h作用达高峰。 血浆蛋白结合率 95%, 主要分布于 肝脏, 其次为肾、 脾、 睾丸、 肾上腺等。 83%经胆汁排泄。 t 1/2 约 3h。 普伐他汀(pravas tat in )本身具有开环结构, 因此, 原 形药即具有活性, 而且起效快, 长期治疗药效稳定。 树脂类药物 的吸附反应可降低本药的生物利用度, 故联合应用时, 应间隔一 定时间。 本药原型及代射物均可腎及胆汁排泄, 肝或肾功能不全 者, 可代偿性地调动其它潜在的排泄能力, 故不需减量。 与华法 林 ( warfar in ) 合用, 不影响后者的抗凝作用。 辛伐他汀
( s imvas tat in )为洛伐他汀的衍生物, 本身无活性, 口服吸收后 转化为 P-羟基酸才具活性。 其降低 TC和 LDL-C的作用比洛伐他 汀强。 氟伐他汀(f luvas tat in )结构特点与前述药物不同, 为具 有氟苯吲哚的甲羟戊二酸内酯衍生物, 其吲哚环模拟 HMG-CoA还 原酶的底物, 竟争性抑制该酶的活性, 使胆固醇的前体甲羟戊酸 生成减少; 而其甲羟戊酸内酯链则模拟酶促反应产物甲羟戊酸, 干扰后者合成胆固醇。 不良反应与 pravastat in类似。 但与环孢 素 ( ciclosporin ) 、 digoxin、 warfar in, 抗高血压药、 H2受体 阻断药及非甾体类抗炎药合用比其它他汀类药安全。 阿伐他汀 ( atorvas tat in ) 为新合成的最有效的他汀类药。 与大多数他汀 类药不同, 该药对纯合子家族性高脂蛋白血症仍然有效。 不良反 应轻, 最常见的是胃肠道反应, 该反应与剂量无关。
麦角甾醇是制备维生素 D, 氢化可的松, 黄体酮和芸苔素内 酯的原料, 同时它也是真菌细胞膜的重要组分。 麦角 -7, 22 -二 烯 -3p-醇, 过氧化麦角笛醇是极具潜力的抗肿瘤药物。
