In‐Silico Exploration of the StreptomeDB Database for Potential Irreversible DprE1 Inhibitors toward Antitubercular Treatment

open access: yesChemistryOpen, Volume 14, Issue 11, November 2025.
StreptomeDB‐derived nitro compounds are screened against Mycobacterium tuberculosis decaprenylphosphoryl‐D‐riboseoxidase (DprE1) . Covalent docking, molecular dynamics simulations, and molecularmechanics/generalized Born surface area analyses identify hydroxythaxtomin and lajollamycin B as potent DprE1 inhibitors, surpassing the reference PBTZ169 in ...
