Identification and Use of Non-Peptide Analogs of RNAIII-Inhibiting Peptide for the Treatment of Staphylococcal Infections

摘要

RNAIII inhibiting peptide (RIP) has been established as an effective inhibitor of staphylococcal infections. Non-peptide small molecule analogs based on a pharmacophore conforming to the putative atomic structure of RIP, can be identified by computer screening of that pharmacophore against established libraries of known small molecules other than peptides. One such identified structural analog is hamamelitannin. When tested for effective inhibition of staphylococcal infections, hamamelitannin demonstrated inhibition similar to that exhibited by RIP. Other analogs can be identified and similarly used.
