Abstract

Linear and bicyclic analogues of the peptide natural product, celogentin C, have been prepared in which the sidechain–sidechain crosslinks in celogentin are omitted or replaced with a mesitylenyl moiety. The simplified bicyclic peptides display moderate antibacterial activity, potentially through inhibition of bacterial protomicrotubule formation, while the linear analogs show higher antibacterial activity through a possible membrane disruption mechanism.
