Objective To devise and synthesize 1,2,3-triazole-substituted matrine derivatives and study the antitumor activities of the derivatives. Methods Taking matrine as the starting material, the target compounds were synthesized by hydrolysis reaction, N-alkylation reaction, and click reaction. Their antitumor activities of the synthesized target compounds were evaluated for HeLa, MCF-7, and HepG2 cells by MTT assay. Results Nine 1,2,3-triazole-substituted matrine derivatives were synthesized. Their structures were characterized by 1H-NMR,13C-NMR, and HR-MS. MTT assay showed that some matrine derivatives exhibited antitumor activities. Compound 5h showed good antitumor activity against MCF-7 and was superior to the parent compound matrine. Conclusion Some derivatives have good antitumor activity and provide a basis for further optimization.
