Chemical structure of Angiotensin II Antipeptide

GA20764

Angiotensin II Antipeptide

Also known as (4S)-4-amino-5-[[2-[[(2S)-1-[[(2S)-1-[[(2S)-1-[[(2S)-1-[(2S)-2-[[(1S)-1-carboxy-2-methylpropyl]carbamoyl]pyrrolidin-1-yl]-3-(4H-imidazol-4-yl)-1-oxopropan-2-yl]amino]-3-methyl-1-oxobutan-2-yl]amino]-3-(4-hydroxyphenyl)-1-oxopropan-2-yl]amino]-3-methyl-1-oxobutan-2-yl]amino]-2-oxoethyl]amino]-5-oxopentanoic acid

The sequence of this “anti-angiotensin II“ peptide has been deduced from the antisense mRNA complementary to the human angiotensin II mRNA· The resulting octapeptide shows 50% sequence homology with angiotensin II· It acts, however, as an antagonist of different physiological actions of angiotensin II, such as uterine contractions or hypertensive responses in the rat
