GA20277

(p-Iodo-Phe⁷)-ACTH (4-10)

Also known as (4S)-4-[[(2S)-2-amino-4-methylsulfanylbutanoyl]amino]-5-[[(2S)-1-[[(2S)-1-[[(2S)-1-[[(2S)-1-(carboxymethylamino)-3-(1H-indol-3-yl)-1-oxopropan-2-yl]amino]-5-(diaminomethylideneamino)-1-oxopentan-2-yl]amino]-3-(4-iodophenyl)-1-oxopropan-2-yl]amino]-3-(1H-imidazol-5-yl)-1-oxopropan-2-yl]amino]-5-oxopentanoic acid

p-Iodophenylalanine-containing ACTH 4-10 inhibited the α-MSH activation of the melanocortin MC?, MC? and MC? receptors· It is thus a nonselective melanocortin receptor antagonist
