Drug-resistant tuberculosis (MDR-TB) is a problem in Peru, because it is one of the countries with the highest burden of the disease according to the WHO. About 50\% of multidrug-resistant strains are resistant to pyrazinamide (PZA), a first-line drug whose importance lies in its activity against latent bacilli and in the reduction of treatment times. PZA is a prodrug that is converted to its active form of pyrazinoic acid by the bacterial enzyme pyrazinamidase (PZase). In order to evaluate possible drug candidates against TB, the couplings of PZA metal complexes against the PZase of PZA-susceptible and resistant strains (D49N, H51R, H57R, H71Y and V139A) will be determined and evaluated with molecular docking. In addition to observing the structural stability through molecular dynamics. Our results show that monodentate complexes are the ones that best couple to apo-enzymes. In addition, great stability is shown during molecular dynamics run times, except in D49N. These results could contribute to the development of metallopharmaceuticals using bioinformatic techniques.
