Anti-proliferative and anti-inflammatory activities of entophytic Penicillium crustosum from Phoenix dactylifer

Abstract

Natural sources have been and will remain an inspiration source for modern chemistry. The current study investigates the antiproliferative and anti-inflammatory action of the ethyl acetate fraction of Penicillium crustosum from Phoenix dactylifera. This paper reports the isolation of P. crustosum from leaves of P. dactylifera and the antiproliferative activities of ethyl acetate fraction on cancer cells. To reach this goal, the anti-proliferation and cytotoxicity effects were evaluated by MTT and LDH assay respectively. The quantitative real time PCR technique was used to investigate IL-6 and IL-8 gene expression. Our results revealed higher anti-proliferative activity against HepG2 (82µg/ml) than MCF7 (126µg/ml) and inhibited the migration of the cell lines. The ethyl acetate fraction significantly altered LDH levels and reduced IL-6 transcript expression on MCF7 cell line but not in HepG2 cell line which could be specific anti-inflammatory drug in breast cancer cell line. These results suggest that Phoenix dactylifera extract has a potent anti-proliferative and anti-inflammatory action. Further investigation to isolate the active compounds and mode of action is required.
