Novel hybrids of 1,2,3-triazole-benzoxazole: design, synthesis, and assessment of DprE1 enzyme inhibitors using fluorometric assay and computational analysis.

ABSTRACT: Decaprenylphosphoryl-β-D-ribose-oxidase (DprE1), a subunit of the essential decaprenylphosphoribose-2'-epimerase, plays a crucial role in the synthesis of cell wall arabinan components in mycobacteria, including the pathogen responsible for tuberculosis, Mycobacterium tuberculosis. In this study, we designed, synthesised, and evaluated 15 (BOK-1-BOK-10 and BOP-1-BOP-5) potential inhibitors of DprE1 from a series of 1,2,3-triazole ligands using a validated DprE1 inhibition assay. Two compounds, BOK-2 and BOK-3, demonstrated significant inhibition with IC₅₀ values of 2.2 ± 0.1 and 3.0 ± 0.6 μM, respectively, whereas the standard drug (TCA-1) showed inhibition at 3.0 ± 0.2 μM. Through molecular modelling and dynamic simulations, we explored the structural relationships betwe
