一种 ffi醇类衍生物、 其制备方法及用途 技术领域
本发明属于医药化工领域, 涉及一种甾醇类衍生物、 其制备方法 及用途。 背景技术
红曲( o/za ^fermented r ice)是以大米为原料, 经红曲霉 ( 0/7 C )发酵制成的一种紫红色米曲。 红曲古代称丹曲, 是将红曲 霉为主的曲母或酒曲接种于米饭上发酵而成,其色赤红,故又名赤曲、 红米、 红大米、 红糟, 又因主产于福建等地, 故又名福曲、 福米等。
我国利用红曲菌的历史悠久, 从汉代起就用它制曲。 红曲是一味 食疗兼备的传统中药。 早在古代它已被广泛应用于食品着色、 酿酒、 发酵、 中医中药方面。 《饮膳正要》有红曲 "味甘、 平、 无毒" 、 "健 脾、 益气、 温中" ; 《本草纲目》有 "甘、 温、 无毒" 、 "治女人血 痛及产后恶血不净, 擂酒饮之良" ; 《本草衍义补遗》有 "活血、 消 食、 健脾暖胃、 治赤白下痢、 跌打损伤" 等记载。
上世纪 70 年代, 日本 Endo 教授首次从红色红曲霉( Ο/½ r^er)中分离出生理活性物质莫纳克林 K (monacol in K)以来, 众多 国内外学者在红曲霉代谢产物中不断发现生理活性物质, 包括 monaco l in 类化合物, 红曲色素, 降压成分 GABA 及抗氧化成分 dimerumic ac id及最近分离的一些萜类化合物等等。 随着现代生物化 学与药理学的发展, 红曲的降血脂、 降压、 降糖、 抗肥胖、 抗癌、 防 治老年痴呆及骨质疏松等功效不断被挖掘。 从而为传统的红曲增添了 新的内涵。
血脂康胶嚢是北京北大维信生物科技有限公司自主研究的特制 红曲霉发酵制成的高效、 安全的国产现代调脂中药。 适应症为高脂血 症及动脉粥样硬化引起的心脑血管疾病的治疗。 其主要作用机制为通 过抑制 3-羟基 -3-曱基戊二酰辅酶 A ( HMG-CoA )还原酶的活性, 可抑 制内源性胆固醇的合成,降低血清总胆固醇( TC;)、血甘油三酯( TG )、 低密度脂蛋白 (LDL ) 、 升高高密度脂蛋白 (HDL ) 水平。 血脂康胶嚢 是红曲的醇提取物, 它富含洛伐他汀等一系列天然他汀类化合物。 除 了他汀类化合物以外, 血脂康胶嚢中还含有色素类化合物、 异黄酮类 化合物、 醇类化合物、 20种氨基酸、不饱和脂肪酸及多种微量元素。 故尚需要发现新的具有降脂或抑制 HMG-Co A还原酶活性的化合物。
此外, 血脂康中还可能存在一些未知的抗癌成分。 故尚需要发现 新的具有抗癌作用的化合物。
肥胖症作为一种全身性内分泌代谢疾病, 在世界范围内成普遍趋 势。 它不但影响体态和活动, 而且与高脂血症、 动脉粥样硬化、 冠心 病、 糖尿病等疾病密切相关。 肥胖发生的原因是多方面的, 如遗传因 素、 环境因素、 饮食习惯等, 其中高脂饮食是导致肥胖的重要原因。 近年来, 药物治疗是治疗肥胖症的有效手段之一, 通过减少脂肪吸收 达到治疗目的。 胰和胃脂肪酶是肠道中脂肪消化吸收所必需的。 食物 中的脂肪被水解为单酰甘油和游离脂肪酸后, 在肠道被吸收, 然后在 体内重新合成脂肪, 造成脂肪堆积, 最终可导致肥胖。 应用脂肪酶抑 制剂可有效抑制肠道中脂肪酶对脂肪的分解催化作用, 达到减少脂肪 吸收、 控制和治疗肥胖的目的 (陈瑾等.肥胖的药物治疗研究进展.中 华中医药学刊, 2007, 25 (5) : 947-948; 吴静等. 肥胖的药物治疗进 展. 医学综述, 2006, 12 (11) : 693-693。 )
目前, 美国 FDA只批准了 2 种药物可以长期用于肥胖症治疗: s ibutramin (西布曲明,中枢神经作用减肥药)和 or l i s tat(奥利司他, 胃肠道脂肪酶抑制剂)。但这两种药都有明显的不良反应: s ibutramin 的副作用主要有口渴、便秘、 头晕和失眠, or l i s tat的不良反应主要 是胃肠道症状, 常见的有腹泻腹痛、 油性斑点、 胃肠胀气等, 其长期 效果也有待于进一步评价。
因此, 目前亦尚需要发现新的具有抑制脂肪酶作用的药物。 发明内容

1. 化合物的理化数据
白色粉末, 旋光度: [a] 25 D -50.00 (c 0.118, CH2C12: MeOH = 1: 1) ;
UV光谱中有三个最大吸收峰,分别为 ax(CH2Cl2: MeOH) = 271.6 nm; 282.2 nm, 293.8 體。
FT-IR ( KBr, cm— 1 )光语: 3392 ( -OH ) , 2969, 2933 (饱和碳氢), 1652, 1647 ( C=C ) , 1456, 1378 (偕二曱基) 。
2. 分子式的确定 HR-ESI-MS给出的 »A 483. 3104 [M+Na] + (ca l cd. 483. 3081, err 2. 3),推断为该化合物的分子量为 460. 32。在 -MR和 13C-NMR显示, 共有 40个氢信号和 28个碳信号。 从 DEPT显示, 有 6个季碳, 10个 CH , 6个 CH2及 6个 CH3。 在 13C-NMR中, 117. 2 ppm, 119. 6 ppm, 139. 1 ppm及 140. 6 ppm 处有 4个烯碳信号。 与 HSQC图与 13C-NMR图结合分 析, 70. 5 ppm, 72. 4 ppm, 74. 5 ppm, 80. 4 ppm, 83. 8 ppm及 84. 4 ppm 处存在与氧原子相连的 6个碳。 结合分子量和 、 13C-NMR及 DEPT信 号图, 如果该化合物拥有 6个氧原子的话分子量超过 460. 32 , 由此推 断该化合物具有 5个氧原子和未体现氢谱信号的 4个氢原子。 从而可 以判断上述 5个氧原子中, 4个氧原子归属为 4个羟基, 另外第 5个 氧原子以醚的形式存在。 根据上述分析, 可以确定该分子中有 28 个 碳原子, 44个氢原子及 5个氧原子, 分子式为 C28H4405
3. 结构式的确定
分析该化合物的碳语 ( 13C-NMR及 DEPT ) , 有 28个碳原子, 其中 6个碳为曱基。 基于紫外吸收光语中 271. 6 nm, 282. 2 nm及 293. 8 nm 处的 3个最大吸收与麦角 醇类基本吻合,初步推断该化合物具有麦 角甾醇的骨架。从分子式可以计算得其不饱和度为 7。从而可以推断: 该化合物除了 2个双键和 醇骨架 4个环的 6个不饱和处外, 还有一 个不饱和处而且此处只能是一个环, 由此可以判断该环是由第 5个氧 原子为中心形成的环氧环。 HSQC图与 HMBC相关信号图相结合分析, 与氧原子相连的 6个碳, 分别归属为 4个羟基相连的 4个碳( 70. 5, 72. 4, 74. 5, 80. 4 ppm )及与剩下一个氧原子相连的 2个碳(83. 8, 84. 4 ppm)。 深入的 HMBC图分析, 可以推断第 5个环体系是由 C-16 (83. 8 ppm) , C-17 (66. 9 ppm) , C-20 (80. 4 ppm), C-22 (84. 4 ppm)及氧 原子组成的 5元环。 这不但满足不饱和度, 而且还满足与氧原子相连 的碳原子数。 进一步分析质谱分析系统给出的分子量及分子式, 证实 了上述分析。 综合上述分析可推测该新化合物为: 16, 22-环氧麦角甾 -5, 7 -二烯 _3, 20, 23, 25_四醇即 ( 16, 22_epoxy - ergos ta - 5, 7-d ien-3, 20, 23, 25-tet rao l ) 。 结构式为下面的式 I I所示:
