Peptide 401

Research use only, not for human use.

Peptide 401 is an antimicrobial peptide (AMP) derived from the venom of bees and wasps. Peptide 401 induces mast cell degranulation, activating histamine release from peritoneal mast cells. Additionally, peptide 401 exhibits some anti-inflammatory activity, decreasing paw edema in animal models.

Peptide 401 is an antimicrobial peptide (AMP) derived from the venom of bees and wasps. Peptide 401 induces mast cell degranulation, activating histamine release from peritoneal mast cells. Additionally, peptide 401 exhibits some anti-inflammatory activity, decreasing paw edema in animal models.(In Vivo):Peptide 401 substantially inhibits the oedema provoked by subplantar injection of carrageenin or intra-articular injection of turpentine in the rat. The ED50 of 401 is c. 0.1 mg/kg. The anti-inflammatory effect is assessed by measurement of the increased 125I-albumin content of an injected site in comparison with an uninjected contralateral site. Peptide 401 also suppresses the increased vascular permeability due to intradermal injection of various smooth muscle spasmogens (histamine, bradykinin, 5-hydroxytryptamine (5-HT), and prostaglandins). Peptide 401 (MCD peptide) contains 22 residues and occurs in the venom of the common European honey bee to the extent of about 2% by weight . It has powerful anti-inflammatory activity (at doses as low as 0.1 mg/kg) in a variety of animal models, i.e., hind paw oedema in the rat induced by carrageenin or turpentine, adjuvant arthritis in the rat, and increased skin permeability in the rat resulting from subcutaneous injection of bradykinin, prostaglandin E1 kallikrein, histamine and 5- hydroxytryptamine (5-HT). It has a powerful degranulating effect on mast cells and involves the release of histamine and other pharmacologically active agents.
