Chemical structure of H-Asp-Ala-His-Lys-OH

GA22122

H-Asp-Ala-His-Lys-OH

Also known as (2S)-6-amino-2-[[(2S)-2-[[(2S)-2-[[(2S)-2-amino-3-carboxypropanoyl]amino]propanoyl]amino]-3-(1H-imidazol-5-yl)propanoyl]amino]hexanoic acid

The tetrapeptide DAHK corresponding to the N-terminal sequence of human serum albumin forms a tight binding site for Cu(II) ions· DAHK inhibits Cu(II)-induced oxidative DNA double strand breaks· The tetrapeptide is as effective as HSA in preventing neuronal death induced by CuCl?/ascorbic acid· DAHK may be an effective, small-molecular-weight alternative to HSA as a therapeutic agent for stroke
