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
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。
