Novel Aryl Isonitriles as Antimicrobial Therapy
Researchers at Purdue University have identified a novel class of compounds that have an aryl isonitrile moiety that shows potent inhibitory activity against clinically important strains of MRSA and VRSA, Bacillus anthracis, and Listeria monocytogenes. These compounds demonstrate strong antimicrobial activity against MRSA strains that are resistant to numerous antibiotic classes such as penicillins, aminoglycosides, macrolides, lincosamides, tetracyclines, and fluoroquinolones. Not only are these compounds potent, they do not show any apparent toxicity against mammalian cells up to a concentration of 64 micrometers, compared to other antibiotics that have a narrow therapeutic to toxic concentration range. In addition, analysis implies that cross-resistance between other antibiotics and these aryl isonitrile compounds is unlikely. Hence, these compounds have the potential for use as future alternatives to other antibiotics for the treatment of resistant strains of MRSA and VRSA in clinical settings.
