Abstract:The tylophorine analogue DCB-3501 was totally synthesized by a seven-step reaction including Perkin condensation, free radical oxidative coupling, Swern oxidation, reductive amination and Fridel-Crafts acylation, using 3,4-dimethoxy-benzaldehyde and 3,4-dimethoxy-phenylacetic acid as the raw materials. The structure was confirmed by 1H NMR and ESI-MS. The in vitro cytotoxicity results showed that the IC50 of DCB-3501 against human colon cancer cell HCT116, human gastric cancer cell BGC-823, human hepatic cancer cell HepG-2, human cervical cancer cell HeLa and human large-cell lung cancer cell H460 were 20.0 μmol·L-1, 50.9 μmol·L-1, 2.1 μmol·L-1, 65.8 μmol·L-1 and 30.8 μmol·L-1, respectively.
