The paper reports the solid phase synthesis and pharmacological properties of 24 oxytocin analogues. Basic modifications at position 9 (L- nebo D-beta-(2-thienyl)-alanine, L- or D-3-Pyridylalanine) were combined with D-tyrosine(OEthyl) or D-1-naphthylalanine in position 2 and beta-mercaptopropionic acid in position 1. Additional 8 analogues had alpha-aminoisobutyric acid or D-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid in position 9. The analogue having the highest anti-oxytocic activity was [Mpa(1), D: -Tyr(Et)(2), Deg(9)]OT (pA2= 8.68).
