Description
技术领域
本发明涉及一类具有抗菌活性的氯氧喹衍生物,还涉及此类氯氧喹衍生物的制备方法,以及它们在制备抗菌的药物中的应用。
背景技术
7-氯-4-氧代-喹啉,一般被人们称为氯氧喹,分子式为:C9H6ClNO,分子量:179.6,熔点为282-285℃,性状为白色或类白色粉末,其化学结构式如下:
该化合物具有互变异构性,其互变异构体为7-氯-4-羟基-喹啉,二者变化关系如下:
已知氯氧喹是吉林省通化茂祥制药有限公司自行研制开发的国家抗癌新药,属化学药品第一类。该药被列入国家“1035”工程和国家“九五”科技攻关计划;2002年4月,通过科技部生命科学技术发展中心验收;2002年9月,获得了国家知识产权局颁发的“发明专利证书”。2003年4月23日获得国家药品监督管理局颁发的两个新药证书(原料药和胶囊剂)及两个药品注册批件。
早在1946年,Hammer和Surrey就报道了以间氯苯胺和草酰乙酸二乙酯为原料,经缩合、闭环、脱羧等反应合成7-氯-4-羟基-喹啉的方法(J.Am.Chem.Soc.68(1946)113-116)。随后,Roberts和Price报道了一种收率更高的合成路线,即以间氯苯胺和乙氧基亚甲基丙二酸二甲酯为原料,经缩合、关环、脱酸等反应合成7-氯-4-羟基-喹啉的方法,三步反应的总收率高达75%(J.Am.Chem.Soc.68(1946)1204-1208)。与前一方法相比,该方法具有两个方面的优点:(1)关环反应没有5-氯取代的异构体产生;(2)反应总收率高。2009年,Langer等报道了一条更简便的合成路线,即以间氯苯胺和丙二酸亚异丙酯为原料,经缩合和关环两步反应即可得到7-氯-4-羟基-喹啉。该路线对于苯环上具有对称取代卤素原子的苯胺原料,收率较高,但该方法对于苯环单取代的苯胺,则会生成5取代的异构体(Synthesis1(2009)69-78)。
氯氧喹目前以口服胶囊的形式用于临床抗肿瘤治疗,临床证实其有较广的抗瘤谱,单药使用与联合化疗方案疗效相近,尤其对于晚期乳腺癌和非小细胞肺癌更为显著,能明显延长生存期,提高生活质量,且具有毒副反应轻微,无一般抗癌药的骨髓抑制和免疫抑制作用,服用方便的特点。但目前尚无关于氯氧喹抗幽门螺杆菌(其通常缩写为Hp)的报道。
幽门螺杆菌(Hp)是一种单极、多鞭毛、末端钝圆、螺旋形弯曲的细菌。幽门螺杆菌感染是慢性活动性胃炎、消化性溃疡、胃黏膜相关淋巴组织淋巴瘤和胃癌的重要病因,目前临床上多采用三联或四联疗法对患者进行幽门螺杆菌(Hp)根除治疗,但由于幽门螺杆菌(Hp)与其它临床常见病菌的重大差异在于其对抗生素的耐药性和敏感性,常常导致幽门螺杆菌(Hp)根除治疗失败。此外,目前临床常用的抗幽门螺杆菌的药物是克拉霉素、甲硝唑,但它们仍然难以有效地根除幽门螺杆菌(Hp)感染。因此寻找新型结构、机制独特的抗幽门螺杆菌(Hp)感染的药物一直是幽门螺杆菌(Hp)研究领域的热点问题。

实验例1:抗幽门螺杆菌(Hp)活性试验
1.试验菌株:本实验采用的两株菌株为幽门螺杆菌ATCC700392和幽门螺杆菌ATCC700824国际标准测序株,购自ATCC(美国菌种保藏中心),传代次数在10代以内。
2.样品稀释:将待测样品(本发明化合物及对照化合物)先用相应溶媒将其浓度配至2560ug/ml,随后按琼脂二倍稀释法进行二倍稀释。取无菌平皿编号后,于每个培养皿中加1ml药液,再加入19ml已加热融化的选择性培养基(融化后冷至50℃时,加入10%无菌脱纤维兔血),使培养皿中的药物终浓度为128、64、32......0.03、0.015、0.008ug/ml。
3.菌液配制:菌株于37℃微需氧环境培养2-3天,取阳性者用于试验。以接种环挑取单菌落稀释于生理盐水中,以0.5号麦氏比浊管比浊,接种菌量约为106CFU/ml。采用多点接种仪(Denley A400)将细菌接种于含不同药物浓度的琼脂平皿表面。接种后将培养皿置于37℃微需氧环境培养2-3天观察结果,以无菌生长的平皿培养基中所含药物最低浓度为药物对该菌的最低抑菌浓度(MIC)。
试验中同时以克拉霉素、甲硝唑这两种临床常用的抗幽门螺杆菌的药物作为对照。本发明化合物抗幽门螺杆菌(Hp)的结果如下表:
