Abstract

Aim: To investigate the cytotoxic effect of methanol extract of Ptreocarpus erinaceus stem barks against cancer lines (Leukemia cell K562 and lung small cells A549) and its inhibition effects against NF-кB activation and lipoxygenase enzyme. Moreover, phenolic compounds, tannins and flavonoids amounts have been determined.

Study Design: In vitro evaluation of cytotoxic activity, inhibitor effect against NF-кB activation and lipoxygenase; and quantitative determination of total phenolic contents.

Place and Duration of Study: Laboratory of Département de médecine-pharmacopée traditionnelle and Laboratoire of Biologie Moléculaire et Cellulaire du Cancer (February – November 2013).

Methodology: The cytotoxicity of methanol extract from stem bark of this plant against cancer cell lines (Leukemia cell K562 and lung small cells A549), and its inhibition of NF-кB activation in K562 cells and lipoxygenase were studied. Additionally phytochemical composition including phenolic, tannins, flavonoids and flavonols was determined by using standard methods.

Results: At 50 µg/mL, the methanol extract of P. erinaceus inhibited the growth of K562 and A549 cells with inhibition percentage of 46.2±4.0 and 59.4±4.5% respectively. Extract inhibited NF-кB activation at 50 µg/mL (86.5±2.7%), and lipoxygenase activity was significantly inhibited by extract at 100 µg/mL (97.7±0.5%). Phytochemical analysis shows the presence of phenolic compounds, tannins, flavonoids and flavonols in a methanolic extract of Pterocarpus erinaceus stem bark.

Conclusion: Pterocarpus erinaceus stem bark showed significant cytotoxic effect and inhibited NF-кB activation and lipoxygenase. These pharmacological effects could be due to the presence of phenolic compounds, tannins, flavonoids and flavonols.

Keywords: Pterocarpus erinaceus, cytotoxic effect, NF-кB, lipoxygenase
