Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn¡¯t involve a screen. 82294-70-0, C5H5NOS.

In the effort to develop novel quinoline derivatives for the treatment of liver cancer, we synthesized a series of N?-Substituted methylene-4-(quinoline-4-amino) benzoylhydrazides and evaluated their biological activities as anticancer agents. Compounds 5h and 5j were found to be the potent antiproliferative agents against HepG2 cell line with an IC50 value of 12.6 ¡À 0.1 muM and 27.3 ¡À 1.7 muM, respectively. The most effective compound 5h also exhibited potent cytotoxicity against SMMC-7721 and Huh7 cells with IC50 values of 9.6 ¡À 0.7 muM and 6.3 ¡À 0.2 muM, respectively. Inspiringly, both 5h and 5j exhibited lower cytotoxic property in normal cells than hepatic carcinoma cells. Compounds 5h and 5j could down-regulate mRNA level of c-Myc and expression level of c-Myc. Meanwhile, they decreased expression level of anti-apoptotic protein Bcl-2 and increased expression levels of pro-apoptotic protein Bax and cleaved PARP with reference to tubulin. So various assays including cell colony formation, cell cycle distribution, as well as cell apoptosis and migration were performed to understand their antitumor role. It was confirmed that 5h and 5j inhibited the growth of HepG2 cells due to their anti-survival effect, induction of cell cycle arrest and cell apoptosis, and inhibition of cell migration. These results demonstrated that 5h might be as potential lead compounds to develop anticancer agents for the treatment of hepatocellular carcinoma.
