[Lys0] - Bradykinin (Kallidin)

Bradykinins (BK) and related kinins are potent inflammatory mediators produced during acute and chronic inflammation. The two main ‘kinins’ in mammals are the nonapeptide bradykinin, BK (1-9) and the decapeptide kallidin (KD), [Lys0]-BK (1-10) . Their biological actions are mediated by two distinct receptors, termed B1 and B2. BK and [Lys0]-BK are peptides which are released at high nanomolar concentrations into the tear-film of ocular allergic patients.
