In vitro Evaluation of Antiproliferative, Lipoxygenase and Xanthine Oxidase Inhibitory Activities of Artemisia nilagirica (C.B.Clarke) Pamp. Leaf Extracts

Abstract

The current study was performed to screen the extracts of Artemisia nilagirica (C.B. Clarke) Pamp. for antiproliferative and antiinflammatory properties. Antiproliferative activity was assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Antiinflammatory activity was evaluated in terms of lipoxygenase and xanthine oxidase inhibitory activities. Results indicated that out of the 3 extracts tested, methanol extract was found to inhibit Y79 (human retinoblastoma) and MCF-7 (human breast adenocarcinoma) cell lines. The same extract was also found to inhibit lipoxygenase and xanthine oxidase enzymes in a concentration-dependent manner with an IC50 of 128.20±3.39 and 144.23±2.04 μg/ml for lipoxygenase and xanthine oxidase, respectively. The present study highlighted the antiproliferative potential of the plant against cancer cell lines. The extracts inhibited lipoxygenase and xanthine oxidase enzymes. Therefore, this plant could be a valuable source for anticancer and antiinflammatory molecules.
