Abstract
本发明涉及一种具有Ⅰ型PRMT抑制活性的式(I)所示的化合物或其立体异构体、溶剂化物、水合物、前药、稳定的同位素衍生物及药学上可接受的盐:上述化合物极大地改善了对PRMTs制活性,能够用于治疗或预防与PRMTs蛋白调节异常有关的哺乳动物疾病。
Description
技术领域
本发明涉及药物化学技术领域,具体涉及一种具有Ⅰ型PRMT抑制活性的化合物及其应用。
背景技术
蛋白质精氨酸甲基转移酶(PRMTs)家族参与的精氨酸甲基化是一种在细胞核和细胞质广泛存在的翻译后修饰方式,其以S-腺苷-甲硫氨酸为甲基供体,甲基化修饰蛋白精氨酸侧链的氮原子,生成S-腺苷同型半胱氨酸和甲基精氨酸。PRMTs的底物是富含甘氨酸和精氨酸结构域的蛋白质。PRMTs家族包含9种PRMT。根据催化反应类型不同,可将PRMT分为Ⅰ型(PRMT1\PRMT2\PRMT3\PRMT4\PRMT6\PRMT8)、Ⅱ型(PRMT5\PRMT9)和Ⅲ型(PRMT7)。Ⅰ型PRMT负责非对称性双甲基化精氨酸(ADMA)、Ⅱ型PRMT负责对称性双甲基化精氨酸(SDMA)、Ⅲ型PRMT负责单甲基化精氨酸(MMA)。
目前已有多篇文献证实Ⅰ型PRMT的表达异常与多种疾病的发生发展密切相关。如PRMT1被发现在白血病、肺癌、肝癌、胃癌、结肠癌、乳腺癌、胰腺癌、头颈部肿瘤等癌症中发挥致癌功能。在恶性胶质瘤中,发现PRMT2在蛋白水平上高表达,并且与不良预后密切相关。在70%的急性髓性白血病(AML)病人中,都可观察到PRMT4的表达有至少两倍的升高。PRMT6被发现在52.6%的胃癌细胞中高表达,并且其表达量与其底物的修饰水平呈显著正相关。同时,由于Ⅰ型PRMT主要负责催化精氨酸不对称二甲基化,体内不对称二甲基化水平的改变与心血管疾病、糖尿病、肾功能衰竭、哮喘和慢性非阻塞疾病有着密不可分的关系。因此,可以说Ⅰ型PRMT的异常表达与多种疾病的发生发展相关。
目前为止,已有的靶向PRMTs的多为甲基供体SAM类似物,但因SAM同时是体内其他甲基转移酶的甲基供体,因此这类抑制剂缺乏选择性,存在严重的脱靶问题。

同位素实验是通过[3H]标记Ⅰ型PRMT甲基供体SAM中的甲基,在正常反应体系中PRMT酶将催化SAM上[3H]同位素标记的甲基转移到精氨酸底物上,若PRMT的甲基转移酶活性被抑制则在底物多肽中无法检测到同位素信号,以此评价化合物对PRMTs甲基转移酶活性的抑制程度。
首先将精氨酸甲基转移酶(PRMTs)、多肽底物和[3H]标记的甲基供体S-腺苷基甲硫氨酸([3H]-SAM)溶于Tris的缓冲溶液中,并把实施例化合物溶解或稀释至待测浓度加入反应板中。接着向已加入化合物的反应板中加入15μL蛋白酶溶液室温孵育15分钟,再加入5μL多肽底物溶液和[3H]-SAM溶液开始反应,室温孵育60分钟,最后通过加入5μL冷的终止试剂终止反应。将最终的反应体系混合液吸25μL加入到Flashplate中室温孵育60分钟,并用含有0.1%的Tween-20的蒸馏水洗去非特异性结合的同位素标记物,放入检测仪(Microbeta)中读取信号值,按照公式计算抑制率,通过GraphPad Prism 8.0软件拟合得到IC50值。(表中,+++++表示IC50<5nM;++++表示5nM≤IC50<10nM;+++表示10nM≤IC50<100nM;++表示100nM≤IC50<1μM;+表示1μM≤IC50<20μM;-表示20μM≤IC50)
