Abstract/OtherAbstract:
We previously reported the potential of a novel small molecule 3-amino-6-(3-methoxyphenyl)thieno[2.3-b]pyridine-2-carboxamide (YL326) as an anticancer agent. In the present study, we investigated the anticancer effects and possible mechanisms of YL326 in vitro. We found that YL326 treatment significantly inhibited human hepatic carcinoma cell proliferation in vitro, and the HepG2 cell line was the most sensitive to its treatment. The inhibition of cell proliferation correlated with G(0)/G(1) phase arrest, which was followed by apoptotic cell death. The YL326-mediated cell-cycle arrest was associated with the downregulation of cyclin-dependent kinase (CDK) 2, CDK4 and CDK6 but not cyclin D1 or cyclin E. The phosphorylation of the retinoblastoma protein (Rb) was also observed. YL326 treatment induced apoptotic cell death via the activation of PARP, caspase-3, caspase-9 and Bax as well as the downregulation of Bcl-2. The expression levels of p53 and p21 were also induced by YL326 treatment. Moreover, YL326 treatment was well tolerated. In conclusion, YL326, a novel cell-cycle inhibitor, notably inhibits HepG2 cell proliferation through the induction of G(0)/G(1) phase arrest and subsequent apoptosis. Its potential as a candidate anticancer agent warrants further investigation.
