Abstract

A novel series of ciprofloxacin-dithiocarbamate hybrids 7a - 7l were designed, synthesized, and evaluated against Gram-positive and Gram-negative bacteria. A significant part of the title compounds showed considerable antibacterial activity against Gram-positive species. The most potent compound against Gram-positive bacteria was 2-chloro derivative 7h and the most potent derivative against Gram-negative bacteria was 3-chloro compound 7i. In vitro antibacterial evaluation of compound 7h against clinically isolated bacteria methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) showed that this compound acted better than ciprofloxacin against the latter bacteria. Docking study of compound 7h in the active site of S. aureus DNA gyrase revealed that this ciprofloxacin-dithiocarbamate derivative interacted with the main components of the active site of the enzyme.

CRISPR & Staphylococcus

CRISPR-Cas system enables the editing of genes to create or correct mutations. Staphylococci are associated with life-threatening infections in hospitals, as well as the community. Here is the latest research on how CRISPR-Cas system can be used for treatment of Staphylococcal infections.
