A series of eighteen derivatives of marine sesquiterpene quinone avarone and its model system tert-butylquinone with amino acids has been synthesized by nucleophilic addition of amino acids to the quinones. In vitro cytotoxic activity toward human cancer cell lines (HeLa, A549, Fem-X, 1(562, MDA-MB-453) and normal MRC-5 cell line was determined. Several compounds showed very strong inhibitory activity with IC50 values less than 10 mu M. Avarone derivatives were more active than the corresponding tert-butylquinone derivatives. The results of the cytofluorimetric analysis of cell cycle of HeLa cells showed that apoptosis might be one of possible mechanism of action of these compounds in cancer cells. In order to examine the influence of caspases on cell death, the apoptotic mechanisms induced by the tested compounds were determined using specific caspases 3, 8 and 9 inhibitors. For all compounds antibacterial activities against six strains of Gram-positive and four strains of Gram-negati...ve bacteria were determined, as well as antifungal activity against three fungal species.
