摘要

By coupling of Tos-Cys (BzL)-Tyr-Phe-Glu (NH2)-Asp (NH2)-Cys (BzL)-N3 (1) with H-Pro- Lys (Tos)-D-Ala-NH2 (II), H-Pro-Lys (Tos)-Ala-NH2 (Ill), and H-Pro-Lys (Tos)-Etda (Tos)(IV) the protected D-Ala 9-lysine-vasopressin (V), Ala 9-lysine-vasopressin (VI), and 9- ethylenediaminelysine-vasopressin (VII) were prepared which after reduction by sodium in liquid ammonia, aeration, and purification by continuous carrier· free electiophoresis ...
