ALB and tuberculosis: The fact that some of the compounds studied here have lower MIC values against the mutant Mtb than INH and, simultaneously, present both a higher affinity for HSA and a potential to permeate more easily membrane barriers due to their enhanced lipophilicity, makes rather interesting to continue exploring the chemical space around INH based on the structures of the two derivatives INH-C10 and N34, in view of future development of new MDR-TB agents.
