Background: Mycobacterium tuberculosis (Mtb) is the organism that causes tuberculosis to develop (TB). In 2019, 10 million individuals worldwide contracted tuberculosis, with 1.4 million people dying from the disease each year (World Health Organization, 2021). Hydrazones-hydrazide-based drugs have been shown to be bactericidal against M. tuberculosis replication. Objectives: We herein intended to synthesize a series of acid hydrazones (3a-3l) by condensing 4-nitrobenzohydrazine with substituted aromatic acids in ethanol at room temperature. Materials and Methods: All newly synthesized compounds were characterized by standard spectroscopic techniques. Synthesized compounds were then tested for anti-mycobacterial analysis, H37Rv strains. Molecular docking analysis was performed for three crystal structures of 1ENY, 1TED and 2FUM Mycobacterium tuberculosis receptors. Results: Among all tested molecules, 3i (MIC: 50 μg/mL) and 3b (MIC: 50 μg/mL) were found to best ligands for further development of new anti-TB drug. We noticed that our proposed molecules were having higher docking scores that corresponding standard anti-TB agents such as Ciprofloxacin and Isoniazid. Synthesized compounds were found to have Drug-Likeness properties when tested with Lipinski’s filter for drug-likeness. Conclusion: From our current study, we wish to propose N'-arylidene-4-nitrobenzohydrazides as anti-TB agents. Agents with such system can be developed in future for developments into active lead molecules.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
