Tuberculosis (TB) caused by the Mycobacterium tuberculosis (MTB) pathogen is a serious contagious illness that endangers the public's health. However, TB is treatable but due to the result of ineffective and protracted medication, MDR‐MTB and XDR‐MTB were able to develop, making their eradication highly challenging and necessitating potential treatments to be cured. This study aimed to identify the novel inhibitor for the InhA enzyme, a potential target of MTB. Initially, 2721 phytochemicals libraries were screened for ADME/Tox profiling and 49 phytochemicals were filtered out. Moreover, these phytochemicals with reference inhibitor triclosan were docked against InhA (PDB ID: 1BVR)., were showing binding energies ranging from −9.16–−6.3 kcal/mol, whereas triclosan showed −6.90 kcal/mol of binding energy. The docking results reveal that irilone (−9.16 kcal/mol) and aurantio‐obtusin (−8.84 kcal/mol) exhibit promising binding energy and perfectly occupy the binding site of InhA. Furthermore, molecular dynamics simulation (MDS) and MMGBSA studies showed better affinities of selected compounds in terms of stability, compactness, flexibility, and total BFE in complexes with InhA. This study concluded that irilone and aurantio‐obtusin could be promising InhA inhibitors based on their impressive pharmacokinetic profiling, toxicity, binding affinity, and stability. However experimental validation is a subject of further research. [ABSTRACT FROM AUTHOR]
