Anti-Inflammatory Peptide 1 (C45H82N12O14S2), with the sequence H-Met-Gln-Met-Lys-Lys-Val-Leu-Asp-Ser-OH, belongs to the group of synthetic oligopeptides corresponding to a region of high amino-acid sequence similarity between uteroglobin and lipocortin I. The name 'antiflammins' is proposed for those peptides, which are valuable models for the development of novel anti-inflammatory agents of therapeutic importance. Anti-inflammatory peptide 1 possesses a potent anti-inflammatory activity in vivo and is a strong inhibitor of phospholipase A2 (PLA2), whose increased presence and activity results in inflammation and pain at certain bodily sites.
