Description
技术领域
本发明属于临床药物新用途发现领域,具体涉及临床药物在抑制具核梭状杆菌生长中的应用。
背景技术
结直肠癌(Colorectal Cancer,CRC)是第三大常见癌症,常见的病因有异常的隐窝、肿瘤、各种遗传和环境因素等。一般而言,正常人的肠道处于肠道微生态与肠道黏膜屏障的相互作用构成肠道稳态状态,宿主共生影响着人类的营养消化与吸收、能量代谢、生理功能以及免疫调节等重要作用。已有研究表明,肠道微生物群的改变与CRC早期发展有关,且已经确定了特定的微生物种类作为肿瘤发生驱动因素,致病微生物的慢性感染和炎症促进肿瘤的发生和进展,肠道菌群可能会调节局部免疫反应进而影响化疗和免疫疗法。
结直肠癌致病菌中研究最深入的是具核梭状杆菌(Fusobacterium nucleatum,Fn),经测定,正常组织、腺瘤组织、结直肠癌中的具核梭状杆菌丰度逐渐增加,具核梭状杆菌能促进结直肠癌的细胞的增殖、侵袭、转移,导致化疗抵抗。因此,靶向具核梭状杆菌有助于患者的预后和管理。此外,与CRC的发展有关的病原微生物还有厌氧消化链球菌,帕氏单胞菌,脆弱拟杆菌,气孔链球菌和产毒素大肠杆菌等。因此,肠道微生物尤其是致病菌广泛参与到结直肠癌的诱发、促进、转移、预后、耐药等方面,成为治疗结直肠癌的重要靶点。
有文献报道对抗生素、人类靶向药物和食品添加剂的近3000种药物进行了分析,检测到的超过70%的药物-药物相互作用是物种特异性的,20%显示出菌株特异性,揭示了窄谱治疗的巨大潜力。发明人对540余种药物进行了抗菌筛选,对筛选出的药物进行抗病原菌试验,实验结果显示,筛选出的药物能够抑制具核梭状杆菌生长,但是对大肠杆菌,双歧杆菌,脆弱拟杆菌的生长没有影响。

实施例一、窄谱抗具核梭状杆菌临床药物新用途再发现
选取上述药物,用DMSO配制成10mM的母液,测试10μM浓度下对具核梭状杆菌,大肠杆菌,双歧杆菌,脆弱拟杆菌的抑制作用。
(1)具核梭状杆菌(Fusobacterium nucleatum,中国普通微生物菌种保藏管理中心,CGMC C 1.2526)培养:向锥形瓶中加入40mL EG液体培养基(不含马血),用接种环挑取少量菌落于培养基中,置于厌氧盒中,37℃恒温培养,待菌体生长至对数期取用。
