Bacterial GTPases as druggable targets to tackle antimicrobial resistance

Small molecules as antibacterial agents have contributed immensely to the growth of modern medicine over the last several decades. However, the emergence of drug resistance among bacterial pathogens has undermined the effectiveness of the existing antibiotics. Thus, there is an exigency to address the antibiotic crisis by developing new antibacterial agents and identifying novel drug targets in bacteria. In this review, we summarize the importance of guanosine triphosphate hydrolyzing proteins (GTPases) as key agents for bacterial survival. We also discuss representative examples of small molecules that target bacterial GTPases as novel antibacterial agents, and highlight areas that are ripe for exploration. Given their vital roles in cell viability, virulence, and antibiotic resistance, bacterial GTPases are highly attractive antibacterial targets that will likely play a vital role in the fight against antimicrobial resistance.

Small molecules as antibacterial agents have played a crucial role in modern medicine, but the rise of drug resistance has diminished their effectiveness. This review highlights the importance of GTPases as key agents for bacterial survival and discusses the potential of small molecules targeting bacterial GTPases as novel antibacterial agents. It also identifies areas for further exploration.
