Abstract

The emergence of antibiotic resistance over the past several decades has given urgency to new antibacterial strategies that apply less selective pressure. A new class of anti-virulence compounds were developed that are active against methicillin-resistant Staphylococcus aureus (MRSA), by inhibiting bacterial virulence without hindering their growth to reduce the selective pressure for resistance development. One of the compounds CCG-211790 has demonstrated potent anti-biofilm activity against MRSA. This new class of anti-virulence compounds inhibited the gene expression of virulence factors involved in biofilm formation and disrupted the biofilm structures. In this study, the physicochemical properties of CCG- 211790, including morphology, solubility in pure water or in water containing sodium dodecyl sulfate, solubility in organic solvents, and stability with respect to pH were investigated for the first time. Furthermore, a topical formulation was developed to enhance the therapeutic potential of the compound. The formulation demonstrated acceptable properties for drug release, viscosity, pH, cosmetic elegance and stability of over nine months.
