一种苯环丙胺类化合物、制备方法及应用
技术领域
本发明属于药物合成技术领域,具体涉及一种苯环丙胺类化合物、制备方法及应用。
背景技术
肿瘤已经成为威胁人类健康的头号疾病,其发病率逐年上升。随着对肿瘤的深入研究,研究人员发现在肿瘤的发生、发展过程中,遗传物质的改变起了重要作用。同时越来越多的研究证实在基因的核苷酸序列没有发生改变的情况下,仍然会存在基因表达的差异,最终导致疾病发生,如肿瘤和神经退行性疾病等,这种调节机制属于表观遗传调控。表观遗传学指的是在不改变DNA序列的前提下,通过可逆性修饰染色体以调节基因的表达,主要研究内容包括DNA甲基化、非编码RNA改变、组蛋白修饰、染色体重塑等。其中,研究最多的是组蛋白修饰,主要包括多聚ADP核糖糖基化、磷酸化、乙酰化、泛素化、甲基化等。
2004年,哈佛大学施扬教授发现并报道了首个组蛋白赖氨酸特异性去甲基化酶(Histone lysine specific demethylase 1,LSD1),证实了组蛋白甲基化是一种可逆的表观遗传修饰过程。LSD1可在辅酶FAD的参与下特异性去除组蛋白赖氨酸H3K4位和H3K9位的单甲基与双甲基,从而控制基因的转录。LSD1也可通过调节非组蛋白底物如p53、DNA甲基转移酶1(DNA methyltransferase 1,DNMT1)、信号转导和转录激活因子(signaltransducers and activators of transcription 3,STAT3)和E2F转录因子1(E2Ftranscription factor 1,E2F1)的功能而抑制基因表达。
研究表明,LSD1与多种肿瘤的发生、发展密切相关,如前列腺癌、乳腺癌、胃癌、肺癌、结肠癌等,并且LSD1在这些癌症细胞系中的表达量高于正常细胞,且其参与了癌细胞的分裂、分化、迁移、侵袭等过程。抑制癌细胞中LSD1的表达可在一定程度上抑制癌细胞增长、侵袭和转移,诱导癌细胞发生凋亡。因此,寻找高效的LSD1抑制剂具有十分重要的意义。
目前已有多种LSD1抑制剂进入临床阶段研究,充分说明LSD1抑制剂作为抗肿瘤靶点的良好成药性。现阶段进入临床研究阶段的不可逆LSD1抑制剂主要包括TCP、ORY-1001、GSK-2879552、ORY-2001、INCB059872、IMG-7289、TAK-418和LH-1802等(结构如下所示),这些化合物中几乎都含有苯环丙胺片段。
因此,开发新型的含有苯环丙胺结构的组蛋白赖氨酸酶1抑制剂,是靶向抗肿瘤药物研究的重要内容,对新药研发和提高人民健康水平具有重要作用和意义。
