β-scoliidine, present in Japanese solitary wasp venom, protects neuronal cells from oxidative stress

Solitary wasp venoms represent a rich source of molecules of pharmacological interest. Thus, to unravel the content of Scolia decorata ventralis venom, proteomic techniques were used, and two new peptides were determined as its major components, α-scoliidine and β-scoliidine. Interestingly, β-scoliidin was effective in protecting neuronal cells against oxidative stress. Read More →
