A series of new Coumarin hydrazone oxime scaffolds were synthesised as potential anti‐TB agents. The structures of the scaffolds were confirmed by spectroscopic and analytical techniques. X‐ray crystallography confirmed the structure of compound 6‐methyl‐4‐((((Z)‐((E)‐3‐(2‐phenylhydrazono)butan‐2‐ylidene)amino)oxy)methyl)‐2H‐chromen‐2‐one (5a). The coumarin hydrazone oxime scaffolds were tested in‐vitro against the Mycobacterium tuberculosis H37Rv strain, and Vero cells were used to assess cytotoxicity. Compound 5b was obtained as the hit candidate, exhibiting MIC 0.78 μg/mL, showing more potent anti‐TB activity than Rifamycin and comparable activity to Isoniazid. There was minimal cytotoxicity observed against Vero cells for the most active compounds, indicating a good safety‐profile.In addition, the most diligent compound 5b demonstrated substantial binding interactions at the PDB:4DQU enzyme's active site and also displayed greater C‐score value than that of 4DQU ligand which validates the observed results.
