一种9-O-芳基取代小檗碱衍生物的合成和用途的制作方法

本发明属于有机合成和药物领域，具体涉及9-o-芳基取代小檗碱衍生物的合成方法及其在抗菌方面的应用。

背景技术：

小檗碱(bbr)，又名黄连素，常温下为淡黄色粉末。小檗碱是从毛茛科，芸香科和小檗科中提取出的天然生物碱，具有四环异喹啉核心单元，显示出丰富的治疗效力，包括：抗菌[clin.microbial.2014,3,150-153]，肿瘤细胞抑制[(a)j.ethnopharmacol.2015,176,35-48,(b)mini-rev.med.chem.2016,16,104-119]和各种慢性疾病的治疗[adv.exp.med.biol.2016,928,27-45]。在大多数情况下，季铵结构被证明是核心功能组分，然而，这种结构却导致bbr的疏脂性增强，使其难以吸收。因此，高剂量bbr的摄入往往为治疗所需，这不但不经济，从长远来看，高剂量给药可能引起不良反应。

为了改善小檗碱的溶解性和生物利用率以提高其生理活性，学者们对小檗碱结构进行了修饰。已有修饰主要集中在n(7)、c(8)、c(9)、c(12)和c(13)等位置，其中，又以c(9)位的修饰最为成熟。因为c(9)修饰可以通过小檗碱脱甲基的产物小檗红碱经亲核取代反应方便制得。通过这种方法，wu等[bioorg.med.chem.lett.2013,23,305-309]合成了一系列9-o-烷基或9-o-萜烯基取代的小檗碱衍生物，并评价对了它们对人类癌症细胞hepg2和ht-29的抑制作用。相比于小檗碱，衍生物i对ht-29细胞显示出108倍的抗增值活性，对hepg2细胞则是83倍；衍生物ii对hepg2细胞显示出104倍的抗增值活性，对ht-29细胞则是32倍。mistry等[res.chem.intermediat.2016,42,3241-3256]合成了一系列吲哚修饰的小檗碱衍生物并测试了这些化合物的抗氧化特性，与母体小檗碱相比，iii-iv抑制dpph和abts两种自由基氧化的效力大幅度增强。

芳基是一类具有高亲脂性的取代基，然而，它们却很少用于bbr的修饰。据我们所知，迄今只有两个课题组将芳基与c(8)和c12)位偶联。jiang和bai等[rscadv.2017,7,26921-26929]首先通过小檗碱与液溴反应生成12-溴代小檗碱，然后经钯催化的suzuki交叉偶联反应合成了一系列12-芳基小檗碱衍生物并研究了他们的生物活性。相比小檗碱母体本身，这些化合物对缺氧诱导因子hif-1的抑制作用增强，而后者已被证明是众多抗癌剂的靶目标。iwasa等[j.nat.prod.1998,61,1150-1153]合成了8-芳基取代的小檗碱衍生物，它们对金黄色葡萄球菌、枯草芽孢杆菌和肠炎沙门氏菌等的抗菌活性明显高于小檗碱母体。

技术实现要素：

目前，通过在c(9)位引入亲脂性基团是提高小檗碱抗菌活性的较有效的方法之一，主要包括长链的烷烃和氮杂环取代基等。芳烃是另一族已知的亲脂性基团，却从未用于小檗碱的c(9)位结构修饰，原因之一可能是小檗碱结构中的季铵基团使得酚氧阴离子的亲核性减弱，同时卤代芳烃中的c-x键活性较低阻碍了c-o键的生成。本发明通过预先将小檗红碱还原，再通过cu催化的ullmann交叉偶联反应实现了c-o键的构建，经温和i2氧化，首次制得了9-o-芳基取代小檗碱衍生物。

本发明合成方法为：以四氢小檗红碱(3)与碘代芳烃为原料，在cu催化剂、配体、碱存在的条件下，n2保护加热(80-100℃)反应24-48小时，合成9-o-芳基取代四氢小檗碱(4)，再经氧化生成9-o-芳基取代小檗碱(5)，合成路线如下：

其中，芳基包括ph,2-me-ph,3-me-ph,4-me-ph,3,5-me-ph,4-^tbu-ph,4-ph-ph,4-ome-ph,4-cf3-ph,4-ocf3-ph,3-f-ph,4-f-ph,4-no2-ph,4-cooet-ph,4-i-ph；

4-i-ph取代的四氢小檗红碱还可与四氢小檗红碱进一步反应生成9-o-苯基桥连四氢小檗碱二聚体(6)，并经氧化制得9-o-苯基桥连小檗碱二聚体(7)，合成路线如下：

四氢小檗红碱的合成方法如下：

(1)、以盐酸小檗碱1为原料，在高温，减压条件下，脱去小檗碱c9-位上的-ch3得到小檗红碱2；

(2)、小檗红碱2先在盐酸/乙醇条件下质子化，再经硼氢化钠还原得到四氢小檗红碱3。

本发明还提供了所述小檗碱衍生物对金黄色葡萄球菌的抑制用途，结果显示，芳基取代基的引入使得该类小檗碱衍生物的抗菌活性普遍提高，其中，4-f-ph取代小檗碱的最低抑菌浓度低达16μg/ml，与小檗碱母体相比，降低了24μg/ml。

本发明的有益效果：本发明采用还原-偶联-氧化的间接方法首次制得了具有潜在药物活性的9-o-芳基取代小檗碱和9-o-苯基桥连小檗碱二聚体，该方法效率高、底物适用性广，所合成的小檗碱衍生物的抗菌活性明显优于小檗碱母体化合物。基于卤代芳烃的结构多样性和该方法优良的底物适用性，将有望得到生理活性更为优异、药效范围更广的小檗碱衍生物。

实施例17本发明部分化合物的抗菌活性研究

按照本发明实施例1的方法制备的9-o-芳基取代的小檗碱衍生物的体外抗菌药效评估如下：

(1)实验菌种

金黄色葡萄球菌(s.aureus)

(2)实验方法

挑选一个s.aureus菌落于10ml的tsb中，37℃，250rmp摇床中过夜培养，取上述菌液100μl置于新的5mltsb中传代6小时(37℃，180rmp摇床)。传代后的菌液继续用tsb稀释50倍，测od600大约为0.1，备用。将样品5a，5l，5i，7，bbr用去离子水分别稀释成20μg/ml-200μg/ml的溶液，间隔10μg/ml。取稀释后的菌液1ml与样品250μl共同孵育1小时(37℃，250rmp摇床)，对照为稀释后的菌液加水，孵育后将样品稀释10³倍,取100μl均匀涂抹于tsa平板上，放置于生化培养箱中37℃，培养24小时。观察细菌生长情况，记录mic和mbc值。

(3)实验结果

实验结果如下表所示：

由表可知：经过结构改造后的化合物5a，5l，5i，7的mic和mbc值均低于小檗碱母体化合物，其中带有4-氟苯取代基的小檗碱衍生物5l的综合抗菌效果最好。
