Title: 8-Cetylcoptisine, a new coptisine derivative, induces mitochondria-dependent apoptosis and G0/G1 cell cycle arrest in human A549 cells. Author: Han B, Jiang P, Xu H, Liu W, Zhang J, Wu S, Liu L, Ma W, Li X, Ye X. Journal: Chem Biol Interact; 2019 Feb 01; 299():27-36. PubMed ID: 30472432. Abstract: Lung cancer is the worldwide leading cause of cancer-related death. Here, we described the synthesis and the anticancer activity of a novel coptisine derivative 8-cetylcoptisine (CCOP) on lung carcinoma in vitro and in vivo. CCOP inhibited the cell viability of A549, BGC-823, MDA-MB-231, HCT-116 and HepG2 cell lines. In A549 cells, CCOP induced apoptosis, G0/G1 cell cycle arrest and decreased mitochondrial membrane potential (MMP) in a dose-dependent manner. Western blot analysis showed that CCOP increased the expression of Bcl-2-associated X protein (Bax), cleaved caspase 3 and 9, while decreased B-cell lymphoma 2 (Bcl-2), cyclins D and E, cyclin dependent kinases (CDKs) 2, 4 and 6, along with the inactivation of the upstream phosphoinositide 3-kinase (Pi3k)/protein kinase B (Akt) signaling. Further in vivo studies showed that CCOP (10 mg/kg) significantly delayed tumor growth in A549 xenograft nude mice, which is stronger than that of coptisine (100 mg/kg). These data suggested that CCOP could be a candidate for lung cancer therapy.[Abstract] [Full Text] [Related] [New Search]
