In this work, bikaverin was isolated from the mycelium of Gibberella fujikuroi and characterized using 1D (1H and 13C) and 2D (HSQC and HMBC) NMR spectroscopy. Its cytotoxic effect on L5178Y lymphoma cells and antitumor effect on BALB/c mice inoculated with L5178Y cells were evaluated. According to the results, bikaverin showed cytotoxic effect against L5178Y lymphoma cells with an IC50 value of 0.23 μg/mL.The tumor evolution, with and without treatment, was observed in the in vivo study; the group without treatment showed 1,280±128 x 105 cells/mL in ascites volume, and the groups treated with bikaverin at the dose of 1.73 mg/kg/day by intraperitoneal (i.p.) and oral administration, decreased significantly the cell density, and showed 391.5±237 x 105 cells/mL and 580±208 x 105 cells/mL, respectively. The results confirm the cytotoxic effect of bikaverin on cancer cell lines and contribute to show the potential of bikaverin as antitumoral compound in BALB/c mice inoculated with L5178Y lymphoma cells.

There is an unmet need for economical snakebite therapies with long shelf lives that are effective even with delays in treatment. The orally bioavailable, heat-stable, secretory phospholipase A2 (sPLA2) inhibitor, LY333013, demonstrates antidotal characteristics for severe snakebite envenoming in both field and hospital use. A murine model of lethal envenoming by a Papuan taipan (Oxyuranus scutellatus) demonstrates that LY333013, even with delayed oral administration, improves the chances of survival. Furthermore, LY333013 improves the performance of antivenom even after it no longer reverses neurotoxic signs. Our study is the first demonstration that neurotoxicity from presynaptic venom sPLA2S can be treated successfully, even after the window of therapeutic antivenom has closed. These results suggest that sPLA2 inhibitors have the potential to reduce death and disability and should be considered for the initial and adjunct treatment of snakebite envenoming. The scope and capacity of the sPLA2 inhibitors ability to achieve these endpoints requires further investigation and development efforts.
