Chemical structure of Ac-Ile-Glu-Thr-Asp-aldehyde (pseudo acid)

GA20581

Ac-Ile-Glu-Thr-Asp-aldehyde (pseudo acid)

Also known as (4S)-4-[[(2S,3S)-2-acetamido-3-methylpentanoyl]amino]-5-[[(2S,3R)-1-[[(2S)-1-carboxy-3-oxopropan-2-yl]amino]-3-hydroxy-1-oxobutan-2-yl]amino]-5-oxopentanoic acid

The peptide aldehyde Ac-IETD-CHO corresponds to one of the cleavage sites of the inactive 32 kD caspase-3 precursor (amino acids 172-175)· In a concentration range of 0·5 µM, Ac-IETD-CHO·blocked the formation of the p17 subunit and concomitantly induced the accumulation of the 32 kD precursor
