COMPARATIVE ANALYSIS OF THE ANTICANCER ACTIVITY OF ANGIOTENSIN RECEPTOR BLOCKERS - IRBESARTAN AND TELMISARTAN
Journal Title: Asian Journal of Pharamceutical and Clinical Research - Year 2018, Vol 11, Issue 12
Abstract
Objective: Angiotensin receptor blockers (ARBs) are effective hypertensive drugs. Reduction in risk of lung cancer with ARBs was proven in clinical studies. Telmisartan and irbesartan are the second-generation ARBs. This study screens the anticancer activity of these two drugs in a dose-dependent manner using A549 cell line.Methods: Different concentrations of irbesartan and telmisartan were treated on A549 cells and the anticancer activity was evaluated through methylthiazolyldiphenyl-tetrazolium [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] cytotoxicity assay. The dot plot of the cytotoxicity results was used to extrapolate the half maximal inhibitory concentration (IC50) values. Microscopic changes in the cells post-treatment with these drugs were also recorded at ideal concentrations.Results: A reduction in cell viability was noted in A549 cells with increasing concentration of the drug. The IC50 values for irbesartan and telmisartan were 31.1 μg and 15.6 μg, respectively. Microscopic observation of the cells shows more rounded and deformed dead cells on telmisartan- and irbesartan-treated cells when compared with the untreated control.Conclusion: The results confirm the anticancer activity of both the drugs with telmisartan being more efficient. The anticancer activity could probably be due to the role of irbesartan and telmisartan in inhibiting mitogen-activated protein kinase cell survival pathway and local angiogenesis.
