By understanding the rampant infections of Mycobacterium tuberculosis ( Mtb ) and inflammations caused due to the generation of radical species during the Mtb infection, a series of ( E )‐2‐(2‐allylidenehydrazinyl)thiazole derivatives, with dual‐action properties, was designed. The molecules were designed with a considerable variation in Log P , one of the critical parameters in physicochemical properties, and analyzed for their drug‐likeness. For the synthesis, a simple, green, and multicomponent one‐pot synthesis method was developed. The in vitro inhibition potentials were evaluated against Mtb H 37 Rv by the microplate Alamar Blue assay. The results reveal that compound 6 was potent, with a MIC value of 6.5 µg/ml, and showed better interactions with the KasA protein with binding free energy (Δ G ) of −9.4 kcal/mol. Also, the radical scavenging properties were studied to establish the dual‐action properties of the molecules. Compound 9 exhibited promising antioxidant and nitric oxide radical scavenging activities, with 81.7% and 81.0%, respectively, at 1,000‐μg/ml concentration.
