Synthèse de la L‐histidyl‐L‐phénylalanyl‐L‐arginyl‐L‐tryptophanyl‐glycyl‐ϵ‐CBO‐L‐lysyl‐L‐prolyl‐L‐valylamide

Abstract: 1867HBr dans I'acide acetique en presence de m6thyl-ethyl-sulfure et d'eau, ou par HBr dans le diethylphosphite).[a]b = -23" f 1" (c = 1,O; methanol), -10' f 1" (c = 1,4; dim6thylformamide). Spectre UV.: Amax = 280 mp (logs = 3,35), 286 mp (logs = 3,29) dans dimbthylformamide-tributylamine (96 : 4). Soluble dans les alcools et le dimethylformamide, peu soluble dans l'ac6tate d'6thyle et l'eau, insoluble dans 1'6ther. L'hydrolyse acide donne de la serine, de la tyrosine, de la methionine et de l'acide glutamiqu… Show more
