Carbonic anhydrase II (CA II) is crucial for maintaining homeostasis in several processes, including respiration, lipogenesis, gluconeogenesis, calcification, bone resorption, and electrolyte balance. It is a pivotal druggable target which is implicated in glaucoma, renal, gastric, and pancreatic carcinomas, as well as in malignant brain tumours. Therefore, to identify new CA II (bovine) inhibitors, the current study was designed to synthesize a library of 20 new triazole-linked hydrazones (6a-t). All compounds were characterized by using spectroscopic techniques such as NMR and mass spectrometry. The in-vitro evaluation resulted in impressive inhibitory capability against CA II with IC values ranging from 9.10 ± 0.26-48.26 ± 1.30 µM. Among all derivatives, compounds 6a, 6b, 6d, 6k-6m, 6q, 6s and 6t exhibited potent inhibitory potential with 6t deemed as the most active inhibitor. Additionally, kinetic study of the hybrid 6t revealed concentration dependent type of inhibition with K value 7.24 ± 0.0086 µM. Furthermore, molecular docking of 6t correlates well with the kinetic analysis. The in-silico ADMET indicated that most of the synthesized compounds have properties conducive to drug development.
