Assessment of in vitro and in vivo Antimicrobial Activity of an Isonitrosomalononitrile Silver(I) Salt

Abstract

The design and evaluation of antimicrobial activities of an isonitrosomalononitrile silver(I) salt was reported. This highly stable water-soluble silver salt shows Minimum Inhibitory Concentrations (MIC) values ranging from 0.15 to 5 µg/mL towards both sensitive and resistant Gram-positive and negative bacteria. Furthermore, this silver salt has been investigated for its ability to treat a S. aureus infected Galleria mellonella larvae animal model with promising results. Thus, our results demonstrated that 80% of the treated larvae survived after 24h with respect to 10% of the untreated ones, respectively.
