Title: Novel Substituted Heterocyclic Carboxamides as Adrenoreceptor ADRAC2 Inhibitors for Treating Diseases.
Authors: Sabnis RW.
Abstract: We designed and synthesized an optimized library of novel bacterial topoisomerase inhibitors with p-halogenated phenyl right-hand side fragments and significantly enhanced and balanced dual-targeted DNA gyrase and topoisomerase IV activities of Staphylococcus aureus and Escherichia coli. By increasing the electron-withdrawing properties of the p-halogenated phenyl right-hand side fragment and maintaining a similar lipophilicity and size, an increased potency was achieved, indicating that the antibacterial activities of this series of novel bacterial topoisomerase inhibitors against all target enzymes are determined by halogen-bonding rather than van der Waals interactions. They show nanomolar enzyme inhibitory and whole-cell antibacterial activities against S. aureus and methicillin-resistant S. aureus (MRSA) strains. However, due to the relatively high substrate specificity for the bacterial efflux pumps, they tend to be less potent against E. coli and other Gram-negative pathogens.
