Design, synthesis and study of anti-tumor activity of thiazolinone urea derivatives bearing aryloxypyridinone fragments / 药学学报

ABSTRACT

Taking cabozantinib as leading compound, 13 novel small molecular c-Met inhibitors were designed and synthesized based on the obtained structure-activity relationships (SARs) of c-Met inhibitors. The structures of compounds were confirmed by 1H NMR, 13C NMR and HR-MS. In vitro anti-tumor activity was evaluated by MTT method, and the mechanism was preliminarily disclosed by real-time dynamic living cell imaging and flow cytometry analysis. The results indicated that most of compounds showed good inhibition activity against human non-small-cell carcinoma cell A549 and human colorectal cancer cell HT-29 which was superior to cabozantinb. Compounds showed excellent cytotoxity and anti-proliferative activity against HT-29, and promoted cell apoptosis.
