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

ChemistryOpen, 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 ...
