GA20335

(Tyr⁶⁵,Phe⁶⁷)-C5a (65-74) (human)

Also known as 2-[[2-[[2-[[5-amino-2-[[2-[[2-[[6-amino-2-[[2-[[2-[[2-amino-3-(4-hydroxyphenyl)propanoyl]amino]-3-hydroxypropanoyl]amino]-3-phenylpropanoyl]amino]hexanoyl]amino]-3-carboxypropanoyl]amino]-4-methylsulfanylbutanoyl]amino]-5-oxopentanoyl]amino]-4-methylpentanoyl]amino]acetyl]amino]-5-(diaminomethylideneamino)pentanoic acid

(Tyr⁶⁵,Phe⁶⁷)-C5a (65-74), analog of the human C5a anaphylatoxin C-terminal region, behaves like a full agonist of natural complement 5a in its ability to induce shape change (polarization) and the release of β-glucuronidase from human neutrophils (PMNs)
