✦ Synopsis

HELVBTICA CHIMIC,A ACTA which contains only protective groups derived from t-butanol. These may be removed quantitatively, without formation of side-products. p1-24-Corti~otropin (I) is thus obtained directly in an analytically pure state; [uIZ5 = -88,6 f 2" (c = 0,5 in I per cent acetic acid). The biological activity of the product was found to be 106 f 14 USP-U/mg (ACTH). It is equally active on intravenous application in human beings.
