Description
技术领域
本发明属于生物医药技术领域,具体涉及一类盐酸小檗碱衍生物及其制备方法和应用。
背景技术
小檗碱又名黄连素,来源于我国传统植物黄中的一种异喹啉类生物碱,长期以来被用作非处方药物治疗肠道感染和腹泻。近年来,随着研究的不断深入,小檗碱的抗肿瘤作用也逐渐得到认可,尤其是作为临床肿瘤治疗的辅助药物。小檗碱具有广泛的抗肿瘤作用,已有研究表明,其抑瘤谱主要包括肺癌、乳腺癌、鼻咽癌、胃癌、肝癌和肠癌等。
近年来,关于小檗碱的研究,更多地从体外转向体内,这一现象在很大程度上表明,小檗碱在体外细胞模型和体内动物模型上抗肿瘤作用的重现性和转化潜力已经引起了人们的关注。盐酸小檗碱多用于抗炎活性的研究,也能抑制肿瘤细胞DNA、RNA、蛋白质和脂肪合成,可诱导许多肿瘤细胞凋亡,在肠癌、前列腺癌、食管癌、乳腺癌等肿瘤的研究中都有报道。因而在心血管系统、神经系统疾病、肿瘤等疾病方面,将可能有广泛、重要的应用前景,日益受到重视。
综上所述,盐酸小檗碱具有较强的抗肿瘤活性。但是,盐酸小檗碱是一种季铵生物盐,还存在亲脂性差,生物利用度不高等问题。
发明内容
本发明的目的是通过改变盐酸小檗碱的苯环结构,使其成为一种叔胺化合物,在进一步提升其抗肿瘤活性的同时,有利于提高生物利用度。
其中,R为邻、间、对位溴或甲基,间位氯或氨基,对位乙基或丙基。
优选的化学名称和化学结构式分别如下:
A:1-(2-溴苯基)-2-(9,10-二甲氧基-5,8-二氢-6H-[1,3]二氧并[4,5-g]异喹啉[3,2-a]异喹啉;+68.-8-基)乙烯-1-酮
B:1-(3-溴苯基)-2-(9,10-二甲氧基-5,8-二氢-6H-[1,3]二氧基[4,5]异喹啉并[3,2-a]异喹啉-8-基)乙烷-1-酮
C:1-(4-溴苯基)-2-(9,10-二甲氧基-5,8-二氢-6H-[1,3]二氧并[4,5-g]异喹啉[3,2-a]异喹啉-8-基)乙烯-1-酮
D:2-(9,10-二甲氧基-5,8-二氢-6H-[1,3]二氧杂[4,5]异喹啉并[3,2-a]异喹啉-8-基)-1-(邻甲苯基)乙烷-1-酮
E:2-(9,10-二甲氧基-5,8-二氢-6H-[1,3]二氧杂[4,5]异喹啉并[3,2-a]异喹啉-8-基)-1-(间甲苯基)乙烷-1-酮
F:2-(9,10-二甲氧基-5,8-二氢-6H-[1,3]二氧杂[4,5]异喹啉并[3,2-a]异喹啉-8-基)-1-(对甲苯基)乙烷-1-酮
G:1-(3-氯苯基)-2-(9,10-二甲氧基-5,8-二氢-6H-[1,3]二氧基[4,5-g]异喹啉并[3,2-a]异喹啉-8-基)乙烷-1-酮
H:1-(3-氨基苯基)-2-(9,10-二甲氧基-5,8-二氢-6H-[1,3]二氧基[4,5-g]异喹啉并[3,2-a]异喹啉-8-基)乙烷-1-酮
I:2-(9,10-二甲氧基-5,8-二氢-6H-[1,3]二氧杂[4,5]异喹啉并[3,2-a]异喹啉-8-基)-1-(4-乙基苯基)乙烷-1-酮
J:2-(9,10-二甲氧基-5,8-二氢-6H-[1,3]二氧杂[4,5]异喹啉并[3,2-a]异喹啉-8-基)-1-(4-丙基苯基)乙烷-1-酮
盐酸小檗碱反应方程式和制备方法步骤如下:
盐酸小檗碱新型衍生物的制备:称取一定量碱加入醇溶液中,搅拌至碱全部溶解。在三口烧瓶中加入盐酸小檗碱,将配置好的碱性醇溶液加入三口瓶中,0℃搅拌至盐酸小檗碱全部溶解。缓慢加入不同取代基的苯乙酮,0℃搅拌30min,反应液澄清后转为室温反应2h。反应完全后,抽滤,用甲醇溶液反复洗涤,得黄色固体。经柱色谱分离得盐酸小檗碱衍生物。
其中,醇为乙醇、甲醇、异丙醇;碱为氢氧化钠或三乙胺。
不同取代基的苯乙酮为:1-(2-溴苯基)乙烷-1-酮、1-(3-溴苯基)乙烷-1-酮、1-(4-溴苯基)乙烷-1-酮、1-(邻甲苯基)乙烷-1-酮、1-(间甲苯基)乙烷-1-酮、1-(对甲苯基)乙烷-1-酮、1-(3-氯苯基)乙烷-1-酮、1-(3-氨基苯基)乙烷-1-酮、1-(4-乙基苯基)乙烷-1-酮或1-(4-丙基苯基)乙烷-1-酮。
盐酸小檗碱:碱:不同取代基的苯乙酮的摩尔比为1:4~5:1。
后处理中柱色谱分离所用的洗脱剂和洗脱剂体积比为甲醇:二氯甲烷
=1:20。
本发明提供了一种通过诱导前列腺癌和乳腺癌细胞发生细胞周期的阻滞和凋亡,抑制前列腺癌和乳腺癌细胞增殖的新型盐酸小檗碱衍生物。
本发明的优点在于:
(1)改变盐酸小檗碱的苯环结构对活性有促进作用,可有效提高新型衍生物的活性,且具有较高的产率和纯度。
(2)筛选出一种具有比盐酸小檗碱更好生物活性和更强抑制前列腺癌和乳腺癌细胞增殖的新型盐酸小檗碱衍生物。
具体实施方式
下面对本发明的具体实施方式做详细说明。
