Abstract |
As part of the phytochemical studies of the plant genus Glycosmis, the constituents of the plant Glycosmis arborea were investigated. Three new carbazole alkaloids named glybomines A (1), B (2), and C (3), along with known monomeric alkaloids belonging to the carbazole, quinazoline, furoquinoline, quinolone, and acridone classes, were isolated from stems of the plant collected at Mymensing in Dhaka, Bangladesh. Glybomine A (1) is the first example of a 2,5-oxygenated carbazole alkaloid from natural sources. As a primary screening test for anti-tumor promoters, nine alkaloids isolated from this plant have been tested for their inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) induction by the tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA). All alkaloids tested showed inhibitory activity.
