从食品植物研究开发的治疗艾滋病新药三合皂甙
据发
皂苷又名皂甙或皂素,是固醇类或三萜类化合物的低聚配糖体总称,因其水溶液能形成持久泡沫,象肥皂一样而得名,它广泛存在于植物和海洋动物体内。
以上化学成份主要药理作用∶1。增强免疫调节功能。对T细胞具有增强作用,特别是T细胞功能的增强,可以使IL一2(白介素)的分泌提高,而IL一2的功能可以保护T细胞的存活与繁殖。促进T细胞产生淋巴因子,增强诱杀性细胞NK(自然杀伤性细胞)的分化。提高LAK(淋巴因子激活的杀伤性细胞)的活性,从而生物体表现出较强的免疫功能。2。抗肿瘤作用。①对肿瘤细胞有直接毒杀作用和生长抑制作用。②与胆汁酸相结合可以形成较大的混合微团,从而防止结肠癌的发生。③防止上皮细胞增生,使增生细胞正常化,从而起到杀伤肿瘤细胞的作用。3。抗病毒抗HIV作用。主要研究证明可以生物性抑制HIV毒斑的形成,使细胞免疫得到无序保护,进而杀灭HIV。4。抗氧化、抗自由基与抗凝血、抗血栓、抗糖尿病等。通过增加SOD (超氧化物歧化酶)的含量,降低LPO(过氧化脂质),清除自由基,减轻自由基的损害作用,促进修复。可以降低x射线诱发遗传物质损伤的机率,可以通过减少辐射水解产物一自由基,加速自由基的代谢而起间接作用,LPO是自由基代谢产物。可以抑制血小板凝聚,并使血纤维蛋白减少,还可以抑制体内毒索引起纤维蛋白的凝聚作用,并可以抑制凝血酶引起的血栓纤维蛋白的形成。可以抑制纤维蛋白原向纤维蛋白转化,可降低血糖,血小板的凝聚率,有抗糖尿病的功效。
上药相关研究工作仍在继续进行中,期待早日开发成功为更多的患者造福。
附∶
皂甙(saponins)又称皂素,是广泛存在于植物界的一类特殊的甙类,它的水溶液振摇后可生产持久的肥皂样的泡沫,因而得名。
根据皂甙水解后生成皂甙元的结构,可分为三萜皂甙(triterpenoidal saponins)与甾体皂甙(steroidal saponins)两大类。组成皂甙的糖常见的有葡萄糖、半乳糖、鼠李糖、阿拉伯糖、木糖及葡萄糖醛酸、半乳糖醛酸等,常与皂甙元C3位的-OH连接成甙。
皂甙的药理作用
1. 双向调节免疫作用;
2. 抗缺氧和抗疲劳作用;
3. 抗低温应激作用;
4. 抗脂质氧化作用;
5. 对中枢神经系统的作用;
6. 抗致突变作用;
7. 对肾有调节作用,补肾。
Liu said, according to the inventor: food plants from the research and development of new drugs to treat AIDS Kang Sheng Dan 〔tentative name, chemical name: Sanhe〕 saponins from three scientific combination of saponin.
Saponins, also known as saponin or saponin is a steroid or triterpenoid compounds collectively oligosaccharide glycosides, which in aqueous solution to form a durable foam, the same name as the soap, it widely exists in plants and marine animals.
More than the chemical composition of the major pharmacological effects: 1. Immune regulatory function. To enhance the role of T cells, in particular, the enhanced T cell function, can make IL-2 (IL-) secretion to increase, while the function of IL-2 can protect the T cell survival and reproduction. The promotion of T cells to produce lymphokines, and enhance cell Traps NK (natural killer cell) differentiation. Enhance the LAK (lymphokine-activated killer cells) activity, and thus organisms showed strong immune function. 2. Anti-tumor effects. ① to kill tumor cells have a direct role and growth inhibition. ② combination with the bile acid can form large mixed micelles, thereby preventing the occurrence of colon cancer. ③ to prevent the proliferation of epithelial cells, so that the normalization of proliferative cells, which play the role of anti-tumor cells. 3. Anti-virus anti-HIV effect. Biological research can prove that inhibition of plaque formation of HIV drugs, so that the protection of cellular immunity has been disorderly, and then kill HIV. 4. Anti-oxidation, anti-free radical and anti-coagulation, anti-thrombotic, anti-diabetes. By increasing the SOD (superoxide dismutase) content, reducing LPO (LPO), scavenging free radicals and reduce the role of free radical damage and promote repair. Can reduce the x-ray-induced damage probability of genetic material, can reduce the radiation of a hydrolysis product of free radicals, accelerate the metabolism of free radicals into the indirect effects, LPO is a free radical metabolites. Can inhibit platelet aggregation, and reduce fibrin, but also can inhibit the in vivo toxicity index of cohesion from the role of fibrin, and can inhibit thrombin-induced fibrin thrombus formation. Can inhibit fibrinogen conversion to fibrin, can reduce blood sugar, the rate of platelet cohesion, there are anti-diabetic effect.
On drug-related study is still continuing and look forward to the successful development of more patients to benefit.
Attachment:
Saponins (saponins), also known as saponin, is widely present in plants of a special class of glycosides, and its aqueous solution can produce long-lasting after振摇soap bubble-like, hence the name.
After hydrolysis in accordance with saponin Sapogenins generated structure can be divided into triterpenoid saponins (triterpenoidal saponins) and steroidal saponins (steroidal saponins) two broad categories. Saponin composition of common sugar glucose, galactose, rhamnose, arabinose, xylose and glucuronic acid, galacturonic acid, etc., are often associated with C3 Sapogenins-OH-bit connection into effect.
Pharmacological effects of ginsenosides
1. Immunoregulatory role of two-way;
2. Anti-hypoxia and anti-fatigue effect;
3. The role of anti-low-temperature stress;
4. Anti-lipid peroxidation;
5. The role of the central nervous system;
6. Anti-mutagenesis;
7. The adjustment of the kidney, kidney.
