Disruption of the mycobacterial redox homeostasis leads to irreversible stress induction and cell death. Hydroquinone scaffolds, as a new type of redox cycling anti-tuberculosis chemotypes, exhibit potent bactericidal activity against non-replicating, nutrient-deprived phenotypically drug-resistant bacteria. Evidences from microbiological, biochemical, and genetic studies indicate that the redox-driven mode of action relies on the reduction of quinones by type II NADH dehydrogenase (NDH2), generating reactive oxygen species (ROS) of bactericidal level.

Laboratório Associado para a Química Verde-Rede de Química e Tecnologia (LAQV, REQUIMTE), Instituto de Ciências Biomédicas de Abel Salazar, Universidade do Porto, Rua de Jorge Viterbo Ferreira 228, 4050-313 Porto, Portugal.
This study aims to evaluate the efficacy of curcumin (CUR), a natural polyphenol with potent antimicrobial and anti-inflammatory properties, when formulated as solid lipid nanoparticles (CUR-loaded SLN) against . Solid lipid nanoparticles (SLNs) were prepared as a carrier for CUR, which significantly improved its solubility. SLNs made with cetyl palmitate and Tween 80 were obtained via the hot ultrasonication method.
