Abstract
Four new analogs of arginine vasopressin containing β-homo-L-amino acid residue were synthesized by the solid-phase method. The introduced modifications yielded the following peptides:[β-homo Phe3]AVP (I), [β-homoPro7]AVP (II), [Cpp1, Tyr(Me)2, β-homoPhe3]AVP (III), and[Cpp1,Tyr(Me)2, β-homoPro7]AVP (IV). Agonistic properties of I and II, as well as antagonistic properties of III and IV were decreased, more pronouncedly with analogs substituted in the position 3.
