To get chelidonine derivatives with enhanced antiproliferative activity and selectivity, a series of nitric oxide donating derivatives (10a-f and 11a-j) were designed, synthesized and biologically evaluated. Compared with chelidonine, these compounds exhibited lower IC50 values against human hepatoma cells HepG2, breast cancer cells MCF-7, colon cancer cells HCT-116, as well as leukemia cells K562. Compound 11j displayed the strongest antiproliferative activity with IC50 values of 3.91, 6.90, 4.36 and 1.12 μM against the above four cells, respectively. Nevertheless, it showed an IC50 value >40 μM against human peripheral blood mononuclear cells (PBMCs), which demonstrated high selectivity between normal and cancer blood cells. In further mechanism studies, 11j showed the capability to induce K562 cells apoptosis, S phase cell cycle arrest and mitochondrial membrane potential disorder. Besides, 11j was found to be effective in promoting the expression of proapoptotic protein Bad and suppressing the expression of anti-apoptotic proteins Bcl-xL, catalase, survivin, claspin and clusterin.

白屈菜碱衍生物的设计,合成及其与凋亡相关的抗增殖活性。

为了获得具有增强的抗增殖活性和选择性的螯胺碱衍生物,设计,合成了一系列的一氧化氮供体衍生物(10a-f和11a-j)并对其进行了生物学评估。与螯合物相比,这些化合物对人肝癌细胞HepG2,乳腺癌细胞MCF-7,结肠癌细胞HCT-116和白血病细胞K562的IC50值较低。化合物11j对上述四个细胞的抗增殖活性最强,IC50值分别为3.91、6.90、4.36和1.12μM。然而,它显示出对人外周血单个核细胞(PBMC)的IC50值> 40μM,这证明了正常和癌细胞之间的高选择性。在进一步的机制研究中,11j显示了诱导K562细胞凋亡的能力,S期细胞周期停滞和线粒体膜电位障碍。此外,发现11j可有效促进促凋亡蛋白Bad的表达并抑制抗凋亡蛋白Bcl-xL,过氧化氢酶,survivin,claspin和clusterin的表达。
