A series of shorter peptide analogues of Bactenecin7 (RP, PRP, GPRP and RPRP) were synthesized and conjugated to 3-(4-oxo-3,4-dihydroquinazolin-2-yl) propanoic acid to study the effect of conjugation. All the peptides and their conjugates were characterized by analytical and spectroscopic techniques. The synthesized compounds viz., peptides, heterocyclic conjugates and the hydrogenolyzed products were evaluated for antimicrobial activity against a panel of pathogens. The results revealed that all the conjugates have shown enhanced activity than their counterparts. Further, hydrogenolyzed tetrapeptide conjugates (10 and 13) have exerted highly potent activity nearly 3-4 times than the standard drugs used.
