淫羊藿甙在制备用于预防或治疗性功能障碍和血管收缩有关疾病药物中的用途
发明领域
本发明涉及淫羊藿甙在制备用于预防治疗性功能障碍药物中的 用途, 以及与改善血管收缩有关疾病的用途。
背景技术
男性的性功能包括性欲、 阴茎勃起、 射精和性快感, 是在神经- 内分泌系统的调节下, 阴茎血管系统的复杂的生理反映。 故如果上 述系统的某一过程出现异常 既可能引起性欲減退、 阴茎勃起障碍、 射精障碍或阴茎疲软障碍等疾病, 而且, 这种疾病可以单独出现或 相互合并出现。男性性功能障碍的发病率大约占成人男性的 30-60%, 并有随着年龄增加而增加的趋势。 传统的医学把性功能障碍通称为 阳萎、 早泄, 直到最近十年以前, 把性功能障碍的原因大部分被认 为只是心理性原因。 但是随着现代科学技术的发达 已经明确了在 50%以上的性功能障碍患者中发现有神经系、 血管系、 内分泌系疾病 以及患有高血压病、 糖尿病、 服用各种药物等器质性原因。
男性的性功能主要是在有各种性刺激时, 在神经-内分泌系统的 调节下 通过血管系统的复杂的生理反映使阴茎勃起。 这种阴茎的勃 起过程首先是依靠阴茎小动脉的扩张 使阴茎血流量增加, 相继出现 阴茎海绵体平滑肌松弛而海绵体小孔膨胀, 促使血液流入量近一步 增加, 导制阴茎海绵体内压升高, 压迫阴茎白膜下的小静脉阻断血 液流出, 从而导致阴茎海绵体内血液充盈而阴茎坚硬勃起 其强度可 达到插入阴道, 并维持勃起的时间足以达到性高潮而射精。
这种阴茎勃起过程中 阴茎海绵体平滑肌的松弛作用起着关键作 用, 而且阴茎勃起过程受神经内分泌系统的调节。 动物实验表明许 多局布因子影响阴茎勃起功能如去甲肾上腺素( NA )、神经肽 Y (NPY)、 乙酰胆碱(Ach)、 前列腺素(PGE)、 五羟色胺(5-HT)、 降钙素基因相 关肽(CGRP)、 血管活性肠肽(VIP)、 内皮素(EDRF)等。
近来的研究表明, 一氧化氮( NO )在阴茎勃起过程中起重要作用。 当性刺激时 NO由分布在阴茎的副交感神经和非肾上腺素非乙酰胆碱 能神经(NANC )末梢释放, 而且 NO也在分布于血管内皮层的内皮细 胞和阴茎海面体窦内皮细胞释放, NO可激活平滑肌细胞内鸟苷酸环 化酶, 使环嶙酸鸟苷( cGMP )合成增加, 也可激活蛋白酶 G(PKG), PKG可以使钙通道关闭和钾通道开放,两种作用均可引起阴茎海面体 平滑肌松弛导致阴茎勃起。 环磷酸鸟甘(cGMP)又被碑酸二酯酶(PDE) 灭活。
性功能障碍可分为性欲减退,勃起障碍,性高潮障碍和射精障碍。 性功能障碍的原因有血管神经性、 内分泌性、 心理性病变、 糖尿病、 高血压、 脊髓神经损伤、 吸烟等因素均可引起性功能障碍。
传统的观点认为性功能障碍主要是由于心理性原因引起。 治疗上 用口服药如安定剂曲唑酮, 和育亨宾等。 但是这种药物的作用机制 尚不明确, 其疗效不高, 并有不同程度的副作用。
近年来随着弄清阴茎勃起机制, 各种对阴茎海绵体平滑肌有松弛 作用的药物 企图用来诊断和治疗男性性功能障碍, 目前, 已有用血 管扩张剂 如楼束减( aparvarin ), 芬托拉明 (phentolamine)、 前 列腺素 El ( prostajlandin El )等药物 直接阴茎海绵体内注射疗法 来治疗阴茎勃起障碍 获得较满意的疗效。 但是, 这种疗法可以引起 局布疼痛、 持续性阴茎勃起、 阴茎纤维化等副作用故临床上常被限 制使用。
最近, 美国发明的治疗勃起障碍的口服药物磷酸二酯酶 V抑制剂 ( Viagra) 被世人瞩目, 上述药品作为化学性假体仅仅是用来一次 诱发阴茎勃起, 并有不同程度的副作用, 如面红、 头痛、 视觉障碍、 低血压等, 特别是对有心血管疾病的患者安全性有争议值得留心。 因此, 安全而有效的增进人体本能性勃起功能的药物有待于研究 开发, 最近的研究力求于开发安全有效的 NO供体用来治疗性功能障 碍。 .
生药淫羊藿在传统医学界里用来滋补强壮剂的处方中常常作为 一种成份,但是其作用机制尚未弄清。 近来的对淫羊藿有效成份研究 证明淫羊藿中含有许多成份, 如淫羊藿甙、 挥发油、 蜡醇、 州一烷、 植物 醇、 鞣质、 亚油酸等。 近来又分离出微量的 magnoflorin、 淫 羊藿糖甙 A、 epimedin A, B, C、 槲皮素、 脱水淫羊藿甙 -3-0-鼠李 糖甙等。 其中淫羊藿甙目前仅被用做淫羊藿成份分析用标准试剂。 一些研究报告淫羊藿具有抗疲劳作用、 增进免疫功能以及改善肝脏 功能。 但是到目前为止, 还没有关于淫羊藿甙单体用来治疗性功能 障碍的研究报告。
发明目的
本发明的目的是寻找并开发淫羊藿甙新的医药用途
发明简述
本发明人经研究发现, 淫羊藿甙出人意料的具有强烈松弛阴茎海 绵体平滑肌的作用, 还具有对大动脉平滑肌轻度的松弛作用, 其药 理作用与平滑肌细胞内一氧化氮( NO ) - cGMP通路的活性增强有关。 从而可用于改善和增进阴茎勃起功能以及与改善血管收缩有关疾病 的症状。
因此, 本发明涉及淫羊藿甙在制备用于预防治疗性功能障碍的药 物中的用途以及与改善血管收缩有关疾病用途。

实验原理 男性的性功能主要是在有各种性刺激下时, 在神经 -内分泌系统 的调节下 通过血管系统的复杂的生理反映促使阴茎勃起。 这种阴茎 的勃起过程首先是依靠阴茎小动脉的扩张作用 和阴茎海绵体平滑 肌松弛作用, 阴茎海绵体窦膨胀促使阴茎海绵体血液流入量增加, 导制阴茎海绵体内压升高而压迫阴茎白膜下的小静脉以阻断血液流 出, 从而导致阴茎海绵体内血液充盈而阴茎坚硬勃起。 这种阴茎勃 起过程中, 阴茎海绵体平滑肌的松弛作用起着关键作用。 故具对阴 茎海棉体平滑肌有松弛作用的药品有助于阴茎勃起功能。 阴茎海绵 体平滑肌的松弛作用 也受非肾上腺素非已酰胆碱(NANC)能神经和 内皮细胞松弛因子(EDRF)的调节, 而这种 EDRF中 一氧化氮(NO)起 着重要的作用。 NO或含有 NO的物质扩散到平滑肌细胞内, 激活可溶 性鸟苷酸环化酶, 使 cGMP合成增加 而诱发阴茎海绵体平滑肌松弛 促使阴茎勃起。阴茎海绵体内的 cGMP又被碑酸二酯酶 V型失去活性。 所以, 促使阴茎海棉体平滑肌 NO生成增加, 或促进鸟苷酸环化酶活 性, 或抑制磷酸二酯酶的活性的药品, 能使 cGMP合成或活性增加, 促进阴茎勃起故对性功能障碍有治疗作用。 利用阴茎海棉体活体组 织在体外进行实验(in vitro) , 观察药物对其张力的影响, 或测定 药物对嶙酸二酯酶的影响, 是研究药物阴茎勃起功能的有效实验方 法。

实验 3淫羊藿戒对碑酸二酯酶活性的影响
实验方法
1. 人血小板中分离磷酸二酯酶
磷酸二酯酶 V型不仅分布在阴茎海绵体, 还分布在血小板。 利用 血小板分离出磷酸二酯酶 V 型, 分析药物对其活性的影响是一种常 规实验方法。 其方法是将新鲜人血液( 360 gm ) 离心分离(360g) 10 分钟, 得出血小板丰富血浆(PRP) , 再将 PRP离心分离(1400g) 10分 钟沉淀血小板。 取 1ml沉淀的血小板, 用水冷緩沖液(Hepes 20nM, Sucrous 0. 25M, EDTA ImM, 笨甲基磺酰氟化物(PMSF) ImM, pH 7. 2) 混匀 漂浮后, 用超声 波震荡器 (Cell distuptor, Burkard Scientific, Uxbridge, Middlesex, UK)破坏细胞膜。 细胞溶解物 远心分离 (799g) 10分钟后, 在次连续离心分离 (165. 000g) 60分钟, 取上层液用 Pharmacia FPLC (Pharmacia LTD., Milton Keynes, UK) 将复合酶分离出来备用。
为了利用 Mono- Q离子交换色谱法提纯嶙酸二酯酶, 利用 Mono-Q 柱(5ml X 50mm) , 緩冲液 A 5ml和緩冲液 B 10ml反复沖洗后, 远心 分离(165. 000g)得到的上清液 10ml, 放入 Mono- Q 柱, 流速定为 1 ml/min。 再让复合酶的活性成分以 1 ml/分钟的流速通过线性梯度 盐(linear gradient salt) (0-0. 5M NaCl)分析各种酶成分。 在所得 到的各种酶成分分别测定其活性, 收集对活性酶成分, 放入液氮瓶 备用。
2. 筛选抑制酶活性物质
磷酸二酯酶的活性分析在最终反应容量 0. 5ml进行, 而且从加入 酶到反应开始的搡作在水上做准备。分析用緩冲液( Tris 40mM pH 8. 0, MgCl2 10 mM, BSA 0. 125mg/ml, 2-巯基乙醇 3. 75 mM )每次使用新 鲜配制的緩冲液, 被蘇作用物 [2H] cGMP (ca. 28 ci/mmol; ca. 100, 000 οριη/100μΙ)是事前用分析用緩冲液做好准备备用。 PDE V型的活性检测方法是利用 [3H] cGMP标记的同位素两步分析法。 测 定时将 [3H] cGMP 200 μΐ 加入试管内, 再加入被试物质(淫羊藿甙 10— 1QM- 10—4Μ )或对照物用同量 DMS0 )100 μΐ和提纯的碑酸二酯酶 100 μΐ, 再加入緩冲液到 0. 5ml, 在 30°C衡温下反应 20分钟后, 将试管 浸入开水中以终止反应。 反应终了后试管内加入蛇毒(Ophiophagus Hannah; Sigma Chemical Co) 100 L (lmg/ml) , 30°C衡温下孵化 10 分钟, 将 [3H] 5-GMP转化成 [3H]鸟苷。 被转换的 [3H]鸟苷在 AG1-X2 resion (Bio-Rad)反应器中, 利用 NaOH (0. 1 N)在离子交换柱型色 谱分析洗脱后得到的样品, 测定其放射性来分析磷酸二酯酶 V的活 性,
3. 实验结果
本实验结果淫羊藿甙对磷酸二酯酶 V 活性有浓度依赖性抑制作用 (10— 8M, 0. 06%; 10— 7M, 32. 7% ; 10"6M, 56. 2%; 10"5 , 83. 7%; 10— 4M, 99. 9%), EC50 为 0. 43μΜ。 见下表。 淫羊藿甙对磷酸二酯酶 V活性的抑制作用(%)。
