Disclosed herein are derivatives of atrial natriuretic peptides which are characterized by having (at positions 106 and/or 124) a phenylalanyl residue bearing a fluoro or trifluoromethyl substituent on the aromatic portion thereof. Optionally, the exocyclic N-terminal peptide segment and the first cystienyl residue (at position 105) are replaced by an optionally substituted thioalkanoyl residue. The derivatives possess useful diuretic, natriuretic and antihypertensive activities.
