Two Component

The induction of vancomycin resistance in enterococci containing the vanA gene cluster is thought to be controlled by a two-component sensor-response regulator system encoded by vanR and vanS. Eight inducing compounds were identified by screening a panel of more than 6,800 antibiotics and synthetic compounds including the three tested glycopeptides (vancomycin, avoparcin, and ristocetin), two other cell wall biosynthesis inhibitors (moenomycin and bacitracin), two cyclic peptide antibiotics (antibiotic AO341 beta and polymyxin B), and a macrocyclic lactone antibiotic (moxidectin). Induction activity by structurally unrelated antibiotics suggests that the induction signal is not a structural feature of vancomycin.

Peptides are important biomolecules which facilitate the understanding of complex biological processes, which in turn could be serendipitous biological targets for future drugs. They are classified as a unique therapeutic niche and will play an important role as fascinating agents in the pharmaceutical landscape. Until now, more than 40 cyclic peptide drugs are currently in the market, and approximately one new cyclopeptide drug enters the market annually on average. Interestingly, the majority of clinically approved cyclic peptides are derived from natural sources, such as peptide antibiotics and human peptide hormones. In this report, the importance of cyclic peptides is discussed, and their role in drug discovery as interesting therapeutic biomolecules will be highlighted. Recently isolated naturally occurring cyclic peptides from microorganisms, sponges, and other sources with a wide range of pharmacological properties are reviewed herein.
