Abstract/OtherAbstract:
The anticancer activity of the extract of blister beetle, Mylabris cichorii has been documented earlier by us. In the present study, the active principle of M. cichorii was isolated and its anticancer efficacy was evaluated against murine Ehrlich ascites carcinoma (EAC). The isolated bioactive compound was characterized to be cantharidin which showed potent antitumor activity and inhibited the proliferation of Ehrlich ascites carcinoma, both in vivo and in vitro. Cantharidin-treated EAC-bearing mice showed about 82% increase in lifespan at the dose of 0.5 mg/kg/day. In vitro cytotoxicity assay with the 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide test revealed about 50% cell death at the concentration of 25.8 μg/ml. The fluorescence and transmission electron microscopy revealed that EAC cells treated with cantharidin depicted typical apoptotic morphology with chromatin condensation, nuclear fragmentation into discrete masses, and plasma membrane blebbing which deduce towards the death of these cells. Histological examination of the kidney of cantharidin-treated mice showed glomerular and tubular congestion with abnormal Bowman's capsule, thus, indicating a renal toxicity in the host. Cantharidin-induced renal damage in the host was also manifested by the decreased lactate dehydrogenase isozymes and its possible release from the cells.
