Due to increasing of TB cases around the world, the search for new drugs is rising. For viability of a new drug, its time of treatment must be shorter, must be active against resistant strains and/or multidrug resistant strains and must be active against latent strains. Thiosemicarbazones compounds showed previously excellent activity against M. tuberculosis H37Rv. Nanoencapsulation of these compounds inside lipid microemulsions has as purpose to get better results of activity and cytotoxicity in vitro and in vivo. The characterization of thiosemicarbazones compounds non-encapsulated is being performed during the postdoc of Marcelo Miyata student, in the Institute for Tuberculosis Research at University of Illinois at Chicago (UIC) under supervision of Dr. Scott Franzblau. The characterization of these compounds encapsulated aims to compare the results before and after encapsulation, allowing getting similar levels of in vitro activity, increasing the solubility of compounds, improving absorption and activity against M. tuberculosis utilizing mice model.
