| Popis: | Objective: The present study was conducted to screen the cytotoxicity and initiation of apoptosis in MCF-7 human breast tumour cells using the Indian sponge Acanthostylotela cornuta of the Gulf of Mannar. Methods: The crude methanol extract of A. cornuta was fractionated using a reversed phase silica gel column chromatography. The purity of the active fraction of bromopyrrole alkaloids was confirmed with Gas Chromatography-Mass Spectrometry (GCMS). The bromopyrrole alkaloids induce apoptotic changes in MCF-7 cells were studied with electrophoresis, caspase assay, and different staining analysis. The MCF-7 cells were analyzed by Flow cytometry to determine their DNA content. Results: Bromopyrrole alkaloids of A. cornuta showed cytotoxicity against MCF-7 human breast tumour cells with the IC50 value of 8.0μg/ml. The bromopyrrole compounds induced cells exhibited scatted red fluorescence, showing the presence of several residual bodies and condensation of chromatin. Caspase-3, pro-caspase-9, caspase-9 and Poly-ADP-Ribose-Polymerase (PARP) activity were occurred in bromopyrrole alkaloids treated tumour cell. The cell cycle arrest is conceivable that the compound prevented the progression of cell cycle through the G phase resulting from inhibition of survival, leading them to undergo apoptosis. Conclusion: Bromopyrrole alkaloids of A. cornuta possess antitumor activity which was arrested the G phase in cell cycle that clearly indicated its nature as that of antitumour drugs. |
