Background: Hydrazide-hydrazone based compounds are reported for their wider pharmacological potentials. Methods: In present work, we synthesized 10 new Schiff based-aryl-carbohydrazide (3a-3e) and (4a-4e), analogues and characterized further using standard spectroscopic techniques including NMR, mass and FT-IR. Moreover, all synthesized compounds were subjected for in-vitro anti-TB, anti-microbial, antioxidant and anti-MCF-7 cell line studies. Results: Our results suggested that compounds are having strong potencies against studied microbial species (such as 3a, 3b and 3c, (anti-TB activity: MIC value of 1.6 µg/mL; 3c:80.23 % inhibition at 200 µg/mL against MCF-7). Synthesized compounds (3a-3e) and (4a-4e) were also retained with higher docking scores than standards like ciprofloxacin; when studied for their molecular docking analysis against common anti-bacterial (pdb id:1d7u; 3a: -4.909 kcal/mol), common anti-fungal (pdb id:1ai9; 3b: -6.122 kcal/mol) and enoyl acyl reductase enzyme (pdb id:2x22; 3c: docking score: -4.194 kcal/mol)) targets. Conclusion: Thus, considering promising results for Schiff based-aryl-carbohydrazides, these compounds may emerge as new class for the development of potent anti-microbial agents in near future.
