Novel vasopressin analogs have the general schematic formula:
wherein X is selected from the group consisting of H and NH2 and Y is selected from the group consisting of -S-S-, -CH2Sand -SCH2- and A = L when B = D and A = D when B = L. They can be administered to increase the level of Factor VIII and plasminogen activator in a subject's blood. The 1-desamino-1- and 1-desamino-6-monocarba [9-D-Ala-NH2]-arginine-vasopressin analogs can be prepared by coupling a respective select group of amino acid residues in a predetermined sequence. Such a method includes the use of an amino acid residue which can be prepared by reacting beta-mercaptopropionic acid with 4-methylbenzyl bromine in the presence of triethylamine and a mutual solvent.
