Compounds of formula (I): ##STR1## wherein R.sup.1x is hydrogen or methyl, R.sup.2x is hydrogen optionally substituted aliphatic hydrocarbon or acylimidoyl, R.sup.3x is hydrogen or an ester group, and Q.sup.x is cyclic or acyclic nitrogen-containing group. The compounds are potent antibiotics which are resistant to dehydropeptidase I, and are thus useful for the treatment of many microbial infections.

recognition of residues 3-5 of angiotensin by the receptor. Retention of activity by the antiparallel dimer of [Sar1,Cys3,5]-AII in which the peptide backbone is held in an extended conformation was unexpected. Analysis of the conformational constraints imposed in these active analogs suggests that AII agonists bind to their receptor with different backbone conformations in the region of the central tyrosine
