Synthesis and Antitumor Activities of Phenylpyridine Substituted Semicarbazides / 中国药学杂志

ABSTRACT

OBJECTIVE: To design and synthesize phenylpyridine substituted semicarbazides and investigate their in vitro antitumor activities. METHODS: The target compounds were synthesized from acetophenone through condensation, cyclization,hydrazinolysis and reaction with isocyanates. The synthesized compounds were screened for their anticancer potential against different cancer cells viz human hepatocelular carcinoma (QGY-7703), non-small cell lung (NCl-H460) and human breast (MCF-7) cancer cell lines by MTT assay. RESULTS Sixteen novel compounds were obtained, and their structures were characterized by 1H-NMR, 13C-NMR and HRMS. In vitro bioassay indicated that most compounds had a certain degree of antitumor activity. Compound 51 displayed the most potential anticancer activity against these cancer cell lines with IC50 value of 9.15, 10.45 and 12.50 μmol·L-1, respectively. CONCLUSION: The series of compounds show preferable antitumor activities, which are worthy of further study.
