Vasopressin-2 receptor antagonist peptides and uses thereof

Abstract

A peptide may include a sequence having 80% or more amino acid identity with the amino acid sequence of SEQ ID NO. 1, i.e., RPSX1CNLPVKPGPCX2GFFSAFYYSQKX3NKCHSFTYGGCAGNANRFSTX4EKCRRTC X5X6, wherein, X1 is the amino acid residue F or G, X2 is any amino acid residue, except a basic amino acid residue, X3 is the amino acid residue T or D, X4 is the amino acid residue I, L, or E, (i) X5 is V and X6 is G or (ii) X5 is G and X6 is V, and the amino acid located at position 39 is A. Such peptides may have various diagnostic and therapeutic uses.
