In search of more effective antitumor agents, based on the previous results of computer aided drug design. The starting material L-tryptophan reacted with formaldehyde via Pictet-Spengler condensation and followed by oxidation and decarboxylation to afford the intermediate β-carboline. The intermediate was further reacted with halogenated hydrocarbon by N9-alkylation and N2-quaternarization to obtain new β-carboline derivatives. Fourteennovel β-carboline derivatives were synthesized and characterized by 1H NMR, IR, MS and elemental analysis. Compound 5h was further studied by X-ray single crystal diffraction analysis. The antitumor activity of the target compounds was studied by MTT method. The results demonstrated that N2-quaternarized compounds (5a5n) had more remarkable cytotoxic activities in vitro than 9-phenylpropyl-β-carboline (4). The tumor inhibition rates of the selected compounds 5e and 5h in mice bearing Lewis lung cancer. The compound 9 showed inhibition activity on transplanting-tumor growth of Lewis lung cancer.

Key words: β-carboline, synthesis, antitumor activity, structure-activity relationship
