Antibiotic resistance is rapidly emerging as one of the most critical health threats, with resistant microorganisms progressively diminishing the effectiveness of established antibiotics. As a result, the development of therapeutic approaches that effectively target resistant pathogens is of utmost importance. In this study, we developed inhibitors for APH(2")-IVa, a bacterial kinase conveying resistance to aminoglycoside antibiotics. Starting from a hit of a fragment-based screening, we explored the inhibitory motif by structure-based design, ultimately leading to a series of triazole analogues. Advanced analogues displayed promising ADME properties, emerging selectivity vs a panel of human kinases, permeability in both Gram-positive and Gram-negative bacteria, and a moderate antibiotic efficacy for clinical strains of P. aeruginosa. Taken together, our results suggest inhibition of bacterial kinases could be a promising option to reinstall the efficacy of aminoglycoside antibiotics.
