Description
技术领域
本发明属于药物化学领域,公开了具有抗肿瘤活性的含1,2,3-三氮唑和脲结构单元的4-取代-5-氰基-6-氨基嘧啶衍生物、它们的制备方法及其作为一类新的抗肿瘤药物先导化合物的应用。
背景技术
肿瘤是严重危害人类健康而又难以克服的疾病,目前已经上市的抗肿瘤药物也有很多,但这些药物中还是存在一些问题,比如毒性大、靶向性弱以及容易产生耐药性等。因此,新型抗肿瘤药物的研发显得尤为重要。
点击化学,由2001年诺贝尔化学奖获得者美国化学家Sharpless首次提出,目前主要指的是一类Cu(I)催化的叠氮化合物与炔基化合物反应生成1,2,3-三氮唑五元环化合物的反应。由于其反应条件温和、反应产率高,产物后处理简单等诸多优点而在药物先导化合物的优化、化合物库的组建中得到了广泛应用。1,2,3-三唑表现出了多种生物活性,如抗炎,抗过敏,抗结核,抗菌,抗HIV活性等。最近,其在抗肿瘤药物先导化合物发现中的应用受到越来越多的关注。多个研究小组利用点击化学将1,2,3-三唑和其它药效基团进行连接,合成得到了一些具有优秀抗肿瘤活性的化合物。例如Kamal小组在鬼臼毒素中引入1,2,3-三唑(如下式),合成了一系列抗肿瘤活性优于etoposide的化合物(H.M.SampathKumar.EuropeanJournalofMedicinalChemistry,2011,46,1983-1991)。
同时,也有报道证实,嘧啶类化合物以及脲类具有非常广泛的生物活性,例如抗病毒、抗菌、抗炎以及抗肿瘤等。但是将嘧啶类化合物、脲活性片段以及1,2,3-三氮唑五元环活性片段结合在一起研究的报道较少,因此,本研究具有非常重要的价值。将丰富点击化学在药物化学领域的应用,拓宽嘧啶类化合物的研究领域,同时,对进一步研究新型抗肿瘤药物,开发自主知识产权药物具有重要意义。
