Diaminopropionic Acid

Two lysine-vasopressin analogs, [1-β-mercaptopropionic acid, 8-α,β-diaminopropionic acid]vasopressin (IVa) and [1-β-mercaptopropionic acid, 8-D-α,β-diaminopropionic acid]vasopressin (IVb) were prepared by solid phase synthesis. IVa and IVb show a considerable antidiuretic effect (1 079 and 1 000 I.U./mg, resp.) and a low pressor effect (14.0 and 22.8 I.U./mg, resp.). The uterotonic effect of IVa is 0.9 I.U./mg and of IVb 1.72 I.U./mg.
