Development and search of new antimicrobials against Tuberculosis: from screening to pre-clinical studies in vivo


In the last report of the World Health Organization 12 bacteria with high incidence of resistance and more Mycobacterium tuberculosis were determinant in the urgency in research and development (R&D) of new antimicrobials. In 2016 there were 10.4 million new cases of tuberculosis (TB) in the world, of which only 6 million were diagnosed and reported. Resistance to antimicrobials against TB only increases. Currently TB causes more deaths than AIDS and it is estimated that by 2050 deaths from resistant bacterial infections will be the number one cause of death in the world. For more 10 years our group has been developing new strategies to search for new drugs against TB. More than 5,000 compounds from all sources were screened in our laboratory and less than 5% were promising. Among these, we have been able to find a benzofuroxan-derived leader compound that showed excelente activity both in vitro and in vivo and a possible new mechanism of action. As a leading compound we verified the need to improve its activity in resistant bacteria and this is one of the proposals of this project. One the other hand, we understand that nature, as the history of antimicrobials already show us, may be a strategy for a new antibiotic. Thus, as a second strategy we intend to work with more than 60 compounds isolated from plants with known structure and route of synthesis, but never challenged against Mycobaterium tuberculosis. The need for new antimicrobials is urgent, our team is struggling and proposing different strategies to eventually be able to presente a potential new compound for clinical studies. (AU)
