Gastropod, Conus amadis, Venom gland, Antioxidant and HEp-2 Cell line and MTT assay


Objective: The present study was carried out to explore the hemolytic, antioxidant and cytotoxic activity of conotoxins extracted from the venom of C. amadis.

Methods: The crude conotoxin was extracted and tested for cytotoxic, antioxidant activity and cancer cell lines. The cytotoxic activity was studied by brine shrimp cells and in-vitro antioxidant activity were determined by DPPH, Superoxide anion radical scavenging assay and hydrogen peroxide scavenging from active fraction of conopeptides. The active fractions were tested in HEp-2 cancer cell lines at different concentration.

Results: The different dose tested viz 100μg/mL-1, 50μg/mL-1, 25μg/mL-1, 12.5μg/mL-1, 6.25μg/mL-1, and 3.2μg/mL-1 cytotoxicity on HEp-2 cell was observed at the 25μg/mL. HEp-2 cell displayed dose dependent decreased in viability detected as early as 48 hrs. The purified conotoxin was showed remarkable cytotoxicity against HEp-2 cell in a dose depend manner. The isolated conotoxin that produced maximum effect at 100μg/mL-1 and the half inhibitory concentrations (IC50) was 25μg/mL-1 in the concentration of 45.6±0.8%.

Conclusion: The present study revealed that cono-peptides from C. amadis have been used as an accessible source of natural antioxidants as well as anticancer after trial with animal and pre-clinical studies.
