Abstract

Salmonella Typhi is emerging as a drug-resistant pathogen, particularly in developing countries. Hence, the progressive development of new antibiotics against novel drug targets is essential to prevent the spread of infections and mortality. The cell division protein FtsZ is an ideal drug target as the cell wall synthesis in bacteria is driven by the dynamic treadmilling nature of the FtsZ. The polymerization of the FtsZ provides the essential mechanical constricting force and flexibility to modulate the cell wall synthesis. Any alteration in FtsZ polymerization leads to the bactericidal or bacteriostatic effect. In this study, we have evaluated the secondary metabolites of natural compounds berberine chloride, cinnamaldehyde, scopoletin, quercetin and eugenol as potential inhibitors of FtsZ from Salmonella Typhi (stFtsZ) using computational, biochemical, and in vivo cell-based assays. Out of these five compounds, berberine chloride and cinnamaldehyde exhibited the best binding affinity of Kd = 7 μM and 10 μM, respectively and inhibit stFtsZ GTPase activity and polymerization by 70 %. The compound berberine chloride showed the best MIC of 500 μg/mL and 175 μg/mL against gram-negative and gram-positive bacterial strains. The findings support that these natural compounds can be used as a backbone structure to develop a broad spectrum of antibacterial agents.
