Description

一种合成MTH1蛋白抑制剂TH287的方法
技术领域
本发明涉及一种合成MTH1蛋白抑制剂的方法,尤其涉及一种合成MTH1蛋白抑制剂TH287的方法,属于化学成技术领域。
背景技术
MTH1(mut T homolog1)是Mut T的同源酶,是一种核苷酸焦磷酸酶,主要参与DNA损伤修复过程,尤其在肿瘤细胞的DNA复制过程中发挥着重要角色。最新的研究表明,MTH1可以清除肿瘤细胞中受损DNA功能结构的氧化构件,使得肿瘤细胞继续分裂与增殖,从而维持肿瘤细胞的生存,而更为重要的是正常细胞不需要MTH1,因此,MTH1有可能只与异常的细胞生长密切相关,这使得MTH1作为治疗靶点成为人们关注的焦点。
Helge Gad以及Saleh A等(MTH1inhibition eradicates cancer by preventingsanitation of the dNTP pool[J].Nature,Nature508,215–221;Saleh A,C,Warpman-Berglund U,et al.Development and validation of method for TH588 andTH287,potent MTH1inhibitors and new anti-cancer agents,for pharmacokinetic studiesin mice plasma[J].Journal of pharmaceutical and biomedical analysis,2015,104:1-11.)公开了一种TH287(CAS#:1609960-30-6)的结构和用途,其为MTH1蛋白目前最有效的抑制剂且有作为抗肿瘤药物使用的前景,但目前尚无TH287合成路线的相关报道。

在本发明的一个具体实施例中,步骤(1)包括将1.0g 2-氨基-4,6-二氯嘧啶和10mL乙醇投入100mL圆底烧瓶中,再加入0.945g 40%(w/w)甲胺水溶液,回流反应1h,反应温度设定为80℃,反应结束后,减压蒸干溶剂,以石油醚:乙酸乙酯体积比=3:1的混合溶液为洗脱液,通过硅胶柱色谱法提纯得白色固体,即化合物2。
在本发明的一个具体实施例中,步骤(2)包括依次将1.0g化合物2、1.44g 2,3-二氯苯硼酸、30mL乙二醇二甲醚、10mL水以及3.35g碳酸钠投入250mL圆底烧瓶中,氩气保护搅拌30分钟,随后立即加入0.36g四三苯基磷钯,氩气保护回流反应48小时,反应温度设定为90℃;反应结束后,减压除去溶剂,以石油醚:乙酸乙酯体积比=3:1的混合溶液为洗脱液,通过硅胶柱色谱法得白色粉末固体4,即MTH1蛋白抑制剂TH287。
