85–95% of cancers. BIBR1532 is a selective non-nucleoside potent telomerase inhibitor that acts by direct noncompetitive inhibition. Relying on its structural features, three different series were designed, and 30 novel compounds were synthesized and biologically evaluated as telomerase inhibitors using a telomeric repeat amplification protocol (TRAP) assay. Target compounds 29a, 36b, and 39b reported
在细胞周期的每个阶段,端粒在细胞复制和增殖中发挥着关键作用。端粒酶是一种核糖核蛋白,负责维持频繁分裂细胞的端粒长度和染色体完整性。尽管它在大多数人类体细胞中被沉默,但由于端粒酶激活或替代端粒延长,端粒恢复发生在癌细胞中。端粒酶是一种通用的抗癌靶点,在 85-95% 的癌症中都有表达。BIBR1532是一种选择性的非核苷强效端粒酶抑制剂,通过直接非竞争性抑制起作用。根据其结构特点,设计了三个不同的系列,合成了 30 种新型化合物,并使用端粒重复扩增方案 (TRAP) 测定对端粒酶抑制剂进行了生物学评估。目标化合物29a、36b和39b报告了对端粒酶的最大抑制作用,IC 50值分别为 1.7、0.3 和 2.0 μM,而BIBR1532显示 IC 50 = 0.2 μM。化合物29a、36b和39b随后使用活细胞TRAP测定进行了测试,并且能够穿透细胞膜并抑制活癌细胞内的端粒酶。使用 NCI (USA)
