Abstract:
Novel quinoline-dithiocarbamate hybrids were synthesized and designed by the molecular hybridization strategy. All these derivatives were evaluated for their antiproliferative activity against three selected cancer cell lines (MGC-803, HepG-2 and PC-3). Among them, compound 10c displayed the best antiproliferative activity against PC-3 cells with an IC50 value of 0.43 μM. Celluar mechanisms investigated that compound 10c could inhibit the migration against PC-3 cells by regulation the expression levels of E-cadherin and N-cadherin. Compound 10c induced morphological changes of PC-3 cells and regulated apoptosis-related proteins (Bcl-2, Bax and Cleaved-Parp). In addition, compound 10c inhibited tubulin polymerization in vitro with an IC50 value of 4.02 μM. Importantly, compound 10c inhibited the growth of PC-3 cells in vivo with the low toxicity toward mice. These results suggested that compound 10c might be an antitumor agent with potential for treating prostate cancer.
