Synthesis and antitubercular activity of new N-oxide compounds designed to treat multiresistant-tuberculosis

Abstract

A few years ago the World Health Organization (WHO) established as one of the its goals the eradication of tuberculosis by the year 2015. Far from this aim, we reached the year 2016 within 10.4 million new cases of tuberculosis (TB) and 1.3 million deaths worldwide. The emergence of resistant strains is one of the factors that justify the difficulty of reaching the goal proposed by WHO. The increasing number of cases for multidrug resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB) associated with high mortality rates, treatment's difficulties and high costs are current challenges. Bedaquiline is the only drug approved by the US Food and Drug Administration (FDA) for the treatment of MDR-TB and XDR-TB. However, resistant strains of this drug have already been characterized, justifying the need to discover new drugs. For more than 10 years, our research group has been looking to identify compounds with antituberculosis activity. By screening a library containing more than 5.000 molecules, we identified benzofuroxan derivatives with potent anti-TB activity against H37Rv strains and multidrug resistant clinical isolates with minimal inhibitory concentration (MIC 90) values ranging from 1.44 uM to 62 uM. Transcriptome studies have shown that the likely mechanism of action of these molecules is through the inhibition of protein synthesis. In this project, we propose the optimization of this benzofuroxane derivatives using the molecular modification strategy. The molecules will be synthesized, characterized and evaluated against strains of either Mycobacterium tuberculosis (MTB) H37Rv and multi-resistant clinical isolates (characterized phenotypically and genotypically). In addition, the determination of MIC90 intramacrophagical using murine macrophages J774A.1 and the ability of the compounds to inhibit the protein synthesis will be investigated. For the most active compound in vivo assay using infected murine will be performed in order to verify the proof of concept.This study is expected to identify new drug candidates for treatment of multidrug-resistant tuberculosis that may become an alternative to current anti-TB treatment.
