<i>In‐Vitro</i> Antimicrobial, Antidiabetic and Anticancer Activities of <i>Calyptocarpus Vialis</i> Extract and its Integration with Computational Studies

Abstract Calyptocarpus vialis ( C. vialis ), a plant of Asteraceae family exhibits nutritional value, antioxidant properties and has potential for various other biomedical applications. The present study is focused to assess the antimicrobial, antidiabetic, and anticancer potential of C. vialis extract and its integration with computational studies. The antimicrobial activity is performed against the Staphylococcus aureus ( S. aureus ), Bacillus subtilis ( B. subtilis ) pseudomonas aeruginosa ( P. aeruginosa ) , Escherichia coli ( E. coli ) bacteria and Saccharomyces cerevisiae ( S. cerevisiae ) , Candida albicans ( C. albicans ) fungi using disc diffusion method. Maximum Zone of Inhibition (ZOI) of 37±3.2 and 35±2.9 mm is obtained for S. aureus and B. subtilis respectively, whereas ZOI of 39±2.8 mm is obtained against C. albicans at dose of 500 μg/mL. The extract shows strong α‐amylase inhibition activity with IC 50 ~46.8±0.81 μg/mL inferring about its antidiabetic potential. Anticancer activity of C. vialis extract is checked against HCT‐116 and DU‐145 cell lines using 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium‐bromide (MTT) assay, which shows excellent anticancer activity with IC 50 value of 38.09±0.65 μg/ml and 36.34±1.05 μg/ml respectively. The obtained results are further verified using computational studies considering interaction among phytochemicals and selected targets. Extract is found potent for biological activities and promising candidate for development of new drugs.
