Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis and responsible for 10.4 million of new cases in 2015. The treatment of tuberculosis consists of an association of Isoniazid, Rifampin, Pyrazinamide and Ethambutol. However, the cases of drug resistance have become very serious and worrying. Therefore, the research group of Unifesp-Diadema developed new compounds with potential antimycobacterial activity derived from pyrazinoic acid, the main metabolite of pyrazinamide that presented promising results. In the development of new drug candidates favorable pharmacokinetic properties represent a crucial decision point improving the chances of success. These results may be achieved early by using in vitro assays, which are used to predict pharmacokinetic as a screening method prior to in vivo study planning and design. The objective of this project is to perform the permeability characterization, using the Caco-2 monolayer model, and in vitro metabolism, using hepatic microsomes of rats and humans. Furthermore, physicochemical assays, through the evaluation of chemical and ex vivo stabilities and determination of log P by chromatographic method, are going to be performed. The obtained results will support decisions regarding the future of drug candidates and the planning of preclinical trials. (AU)
