Description
技术领域
本发明涉及生物工程技术领域,特指通过感染蝉形成蝉花的蝉拟青霉菌种的液体发酵技术制备麦角甾醇过氧化物的方法。
背景技术
肾细胞癌起源于肾上皮细胞。它占肾脏癌症的90%以上,占所有致命,恶性肿瘤的3%。多达30%的肾细胞癌患者出现局部复发或远处转移,目前的五年生存率不理想。尽管使用一线靶向酪氨酸激酶抑制剂(例如索拉非尼或舒尼替尼)进行肾细胞癌治疗取得了显著进展,但在肾细胞癌治疗中仍需要具有优异效果和安全性的新食品或药物。天然食品和动植物是药物开发的非常宝贵的资源,活性产品的利用是一种抗击癌症的有希望的策略。传统中草药是治疗各种流行病包括癌症的常用药物。迄今为止,在中国传统中医学理论的指导下,许多有效的抗癌配方已经从这些草药中衍生。中药蝉花(Cordycep cicadae)是一种可食用的虫生真菌,由蝉拟青霉感染的蝉若虫形成,并被广泛用于预防和治疗各种疾病。在中国,它已被用于医药和食用超过1000年,经常被推荐用于治疗肺部疾病。最近,越来越多地发现了蝉花及蝉拟青霉菌丝体的抗肿瘤作用,例如妇科癌细胞中的抗增殖和促凋亡特性。麦角甾醇过氧化物是蝉拟青霉的主要活性成分之一(分子式:C28H44O·C6H12O7)。麦角甾醇过氧化物可以从蝉花子实体中术分离出来。麦角甾醇过氧化物具有激活免疫反应和发挥抗癌/病毒效果。最近,越来越多的证据已经发现麦角甾醇过氧化物对肾脏肿瘤、结肠直肠癌,肝细胞癌,前列腺癌,骨髓瘤和白血病的具有抗肿瘤活性。目前麦角甾醇过氧化物可通过色谱方法从毛癣菌,萤火虫,蝉虫草,灵芝等中分离出来。本发明是发明者通过反复实验研究发现,蝉拟青霉通过液体发酵产生菌丝体,从菌丝体中可以分离获得麦角甾醇过氧化物。该麦角甾醇过氧化物同样具备抑制人肾细胞癌的增殖,侵袭/迁移抑制,促肾癌细胞凋亡。
发明内容
针对目前麦角甾醇过氧化物主要来源于植物或药用真菌子实体,受到资源限制的问题、麦角甾醇过养化物由于受到地质环境、气候等影响导致含量不稳定等问题,本发明的目的在于:提供一种通过蝉拟青霉液体发酵获得蝉拟青霉菌丝体,蝉拟青霉菌丝体通过乙醇提取、大孔树脂Amberlite XE-243吸附分离,C-18柱纯化获得具有抑制肾细胞癌的麦角甾醇过氧化物方法。
