Recent studies suggest that Mycobacterium smegmatis, with innate resistance to isoniazid, could be used as a surrogate for MDRTB screening in laboratories without adequate containment facilities. The current study utilized resazurin microtiter assay plate (REMA) to screen common household chemicals and non-steroidal anti-inflammatory drugs (NSAIDs) for anti-tubercular activity against Mycobacterium smegmatis, as a non-pathogenic surrogate of MDRTB. A ligand-based approach was adopted in selecting household chemicals; using molecular docking tools to probe for binding affinity to Enoyl-[acyl-carrier-protein] reductase (InhA), the main target of isoniazid. Among household chemicals and analgesics studied, EDTA and lauric acid showed the highest activity with minimum inhibitory concentration (MIC) of 31 μg/mL and 7.8 μg/mL respectively, while Ibuprofen and aspirin exhibited activity with MIC of 125 μg/mL. Taken together, this study demonstrates the potential use of EDTA, lauric acid or NSAIDs in treatment of drug-resistant tuberculosis, a major contribution of the current study}, number={21}, journal={European Scientific Journal, ESJ}, author={Umesiri, Francis E. and Lick, Ashley and Fricke, Christine and Funk, Joel and Nathaniel, Thomas}, year={2015}, month={Jul.} }
