Abstract

Abstract Novel peptides having potent natriuretic activity are disclosed with the following amino acid sequence: ##STR1## wherein Z is H, acetyl, Boc or Ser-Leu, E is Phe, NMP, OMT, ChA, F is Gly or DAl, G is Ala or Gly, H is Arg or DAr, Pro, Lys or Dly, I is Ile, Met, MeO, MO 2 , Leu, Nle, or Val, J is Aib, αMG or αMA, K is Arg or Lys, L is Ile or Val, M is Aib, Gly, Ala or DAl, N is Ala, NMA, Pro, Phe or NMP, O is Gln, DGl, Ala or DAl, P is Ser, His, Arg or Lys, Q is Gly, Pro, Ala or Dal, R is Leu, Phe or ChA, S is Gly, Ala or Dal, Arg or DAr, T is Asn DAs, Ala or Dal, U is Ser, DSe, Ala or DAl, V is Phe, DPh, Ala or DAl, Y is -OH or -NH 2 and n is 0 or 1. Also included are the lower alkyl esters and the physiologically acceptable metal salts and acid addition salts of the foregoing peptides. Unless indicated otherwise all optically active amino acids have the L-configuration.
