Our results indicate that 1 NSC606985, at nanomolar level, can effectively induce apoptosis in AML cells NB4 and U937 and significantly inhibit the proliferation without cell death in breakpoint cluster region–Abelson murine leukemia kinase-carrying leukemic K562 cells; 2 At such low concentrations, this agent also significantly inhibits the clonogenic activity of hematopoietic progenitors from patients with AML; 3 For apoptosis induction, NSC606985 rapidly induces the proteolytic activation of protein kinase Cδ with loss of mitochondrial transmembrane potential and caspase-3 activation; 4 Co-treatment with rottlerin, a PKCδ-specific inhibitor, completely blocks NSC606985-induced mitochondrial m loss and caspase-3 activation, while the

结果显示：(1)纳摩尔浓度的NSC606985即可有效诱导AML细胞系NB4和U937细胞凋亡并显著抑制含有bcr-abl融合蛋白激酶的K562细胞的增殖；(2)低浓度的NSC606985也显著抑制来自AML病人骨髓的新鲜白血病细胞的克隆形成能力；(3)除了迅速诱导线粒体跨膜电位的崩塌及Caspase-3的活化外，NSC60698也导致蛋白激酶Cδ的水解激活；(4)PKCδ特异的抑制剂rottlerin能够完全抑制NSC606985诱导的线粒体跨膜电位的崩塌和Caspase-3的活化，而Caspase-3特异的抑制剂z-DEVD-fmk仅能部分削弱PKCδ的活化及细胞的凋亡；(5)以移植PML-RARα转基因小鼠产生的白血病细胞建立的模型研究了该化合物对白血病可能的治疗作用。
