Synthetic racemates of abyssinone I and II induces apoptosis through mitochondrial pathway in human cervix carcinoma cells.

Abyssinones I and II are prenylated flavanones existing in plant Erythrina abyssinica showing diverse biological activities including anticancer activities. We synthesized racemic mixtures of these flavanones from corresponding chalcones and herein we report for the first time the molecular mechanisms of cell death, anti-proliferative effect and ability to induce apoptosis in human cervical carcinoma (HeLa) cells. Cytotoxicity was assessed by MTT assay to determine LD50 for prenylated chalcones and their corresponding flavones.
