Megascoliakinin, a bradykinin-like compound in the venom of Megascolia flavifrons Fab. (Hymenoptera: Scoliidae)

Comp Biochem Physiol C. 1984;78(2):473-4. doi: 10.1016/0742-8413(84)90116-6.


The pharmacological and immunological properties of the venom of Megascolia flavifrons are compared with those of bradykinin and a number of bradykinin analogues. It is postulated that this venom contains a peptide, megascoliakinin, with a bradykinin-like sequence of amino acids, elongated at the C-terminal end with an unknown structure.
