<p>Peptides of formula - R1-Tyr-X2-Gly-NR2-CHR3-(CH2)n-Ar (I) - and their salts are new where R1 = H, Me, Et or amidino; R2 = Me or Et; R3 = H or CONH2; X2 = a D-amino acid gp. of formula -NH-CHQ-CO-, where Q = (CH2)mNHC(NH)NH2 and m = 2-4; Ar = phenyl mono- or disubstd. by halogen, NO2 and/or CF3; n = 0-2, provided that n = 1 when R3 = CONH2.</p> |
