Evaluation of pharmacological interaction and bactericidal kinetics of new furoxanic molecules in combination with rifampicin, isoniazid, amikacin, and moxifloxacin against Mycobacterium tuberculosis H37Rv
In this project, we propose to evaluate the pharmacological interactions and possible synergistic effects of rifampin, isoniazid, amikacin, moxifloxacin, and five new furoxanic molecules obtained by the synthesis in LAPDESF (Laboratory of Drug Research and Development)at FCFAR/UNESP, which demonstrated promising against Mycobacterium tuberculosis. This project is part of the Young Researcher Project (No. 2013/14957-5 ) recently awarded under the coordination of Prof.Dr. Rogério Fernando Pavan. The study of new drug combinations to combat Mycobacterium tuberculosis is important to add new drugs to treat tuberculosis and Evaluation of new molecules with potential activity against mycobacteria. Two methods that will be used to study the synergism of molecules are the checkerboard and bactericidal kinetics. The checkerboard method allows evaluating drug combinations that show synergism or not and which are the best synergistic concentrations for two or more molecules. However, with this method, we can not evaluate the synergistic effect over time. By doing the bactericidal kinetic assay it is possible to expose the Mycobacterium to different Combinations of drugs in different concentrations. Every 24 Hours An aliquot of the sample is taken, diluted, plated onto plates, and incubated for counting mycobacteria. Results are expressed in Colony Forming Units per milliliter (CFU/mL). with the data obtained, it is possible to construct a time-kill curve and thus observe the quantitative measure of the intensity of the bactericidal effect.
