Abstract

Syntheses of 12H-pyrido[2,1-a]-β-carbolin-5-ium bromides (15-27) and 11H-pyrrolo[2,l-a]-β-carbo1ines (32-35), structurally related to the tetracyclic alkaloid javacarboline (1) have been achieved via 2 steps routes starting from the respective β-carbolines. Their synthetic compounds showed potent antitumor activities against P-388 murine leukemia cells and PC-6 human lung carcinoma cells.
