A new bradykinin-potentiating peptide (peptide P) isolated from the venom of Bothrops jararacussu (jararacuçu tapete, urutu dourado)

Toxicon. 1992 Jan;30(1):33-40. doi: 10.1016/0041-0101(92)90499-u.

Abstract

Several bradykinin potentiators were identified in the venom of Bothrops jararacussu by chromatographic techniques and biological assays. One of them which was isolated inhibited the angiotensin-converting enzyme in vitro and potentiated the bradykinin-induced lowering of the arterial pressure in the rat.
