Synthesis, Complexation with Pd(II), and Cytotoxicity of Pyridin-3-Ylmethylylidene Derivatives of Methyl Betulonate
摘要
Pyridin-3-ylmethylylidene derivatives of methyl betulonate were synthesized. Six new Pd(II) complexes of them were obtained. The effects of these compounds on A549 (non-small-cell lung carcinoma) and HCT116 cell lines (colon cancer) were assessed by the MTT assay. 3-{(E)-[28-Methoxy-3,28-dioxolup-20(29)-en-2-ylidene]methyl}-1-methylpyridinium tetrafluoroborate exhibited potent cytotoxic activity on HCT116 cell line (IC50 = 7.21 μM).
