Recently, proteolysis targeting chimera (PROTAC) technology is highlighted in drug discovery area as a new therapeutic approach. PROTAC as a heterobifunctional molecule is comprised of two ligands, which recruit target protein and E3 ligase, respectively. To degrade the anaplastic lymphoma kinase (ALK) fusion protein, such as NPM-ALK or EML4-ALK, we generated several ALK-PROTAC molecules consisted of ceritinib
最近,靶向嵌合体的蛋白水解(PROTAC)技术作为一种新的治疗方法在药物开发领域得到了强调。作为异双功能分子的PROTAC由两个配体组成,它们分别募集靶蛋白和E3连接酶。为了降解间变性淋巴瘤激酶(ALK)融合蛋白(例如NPM-ALK或EML4-ALK),我们生成了几种由ceritinib,ALK抑制剂之一和von Hippel-Lindau(VHL)E3配体组成的ALK-PROTAC分子连接酶。在这些分子中,TD-004有效诱导ALK降解并抑制ALK融合阳性细胞系SU-DHL-1和H3122的生长。我们还证实,TD-004在H3122异种移植模型中显着降低了肿瘤的生长。
