GA20033

(Arg⁸)-Vasopressin (4-9)

Also known as (2S)-2-amino-N-[(2S)-4-amino-1-[[(2R)-1-[(2S)-2-[[(2S)-1-[(2-amino-2-oxoethyl)amino]-5-(diaminomethylideneamino)-1-oxopentan-2-yl]carbamoyl]pyrrolidin-1-yl]-1-oxo-3-sulfanylpropan-2-yl]amino]-1,4-dioxobutan-2-yl]pentanediamide

Main metabolite of (Arg?)-Vasopressin (H-1780)· It improved the scopolamine-induced deficit of spatial memory in rats about 10'000 fold more than H-1780 and therefore has the most potent activity of all the endogenous metabolites of H-1780
