Human acute promyelocytic leukemia (APL) is the most malignant form of acute leukemia. The fusion of PML and RARα genes is responsible for over 98% of cases of APL. In this work, we found that a Ru(ii) arene complex, [(η--bip)Ru(en)Cl][PF] (), can selectively react with PML, leading to zinc-release and protein unfolding. Consequently, the degradation of the fusion protein PML-RARα occurs, which causes the differentiation of APL cells. In addition, can also bind to DNA and trigger apoptosis of APL cells. Therefore, acts as a dual functional agent that inhibits the growth of APL cells and induces cell differentiation. In contrast, the other non-selective Ru(ii) compound, though also highly reactive to PML, does not exhibit anti-APL activity. The selectivity of to PML suggests a new strategy for the development of anti-APL drugs using ruthenium agents.
人类急性早幼粒细胞白血病(APL)是急性白血病中最恶性的形式。PML和RARα基因的融合导致了超过98%的APL病例。在这项工作中,我们发现一种钌(II)芳烃配合物,[(η--联苯)Ru(en)Cl][PF](),可以与PML选择性反应,导致锌释放和蛋白质解折叠。因此,融合蛋白PML-RARα发生降解,从而引起APL细胞的分化。此外, 还可以与DNA结合并触发APL细胞的凋亡。因此, 作为一种双功能剂,可抑制APL细胞的生长并诱导细胞分化。相比之下,另一种非选择性钌(II)化合物虽然对PML也具有高反应性,但不表现出抗APL活性。 对PML的选择性为使用钌试剂开发抗APL药物提出了一种新策略。
