© 2022 Elsevier B.V.A new series of imidazolyl hydrazone derivatives IA (1-12) were prepared from a condensation reaction between indoline-2,3-dione (isatin) and 2-benzylidenehydrazinecarboximidamide derivatives. The structure of compounds was elucidated using various spectral techniques including FTIR, 1H NMR, 13C NMR, and HRMS. The proposed structure of IA-2 was determined by single-crystal X-ray analysis. Synthesized compounds were evaluated for their inhibitory action against carbonic anhydrase I and II isoenzymes (hCA I and hCA II), as well as cytotoxicity activity in a cancer cell line (HT-29) and a healthy cell line (NIH 3T3). Among them, some compounds exhibited remarkable CA inhibitory activities compared to a standard inhibitor with Ki values in the range of 13.434 ± 3.278-522.549 ± 360.720 nM for hCA I (Ki value for standard inhibitor = 271.15 ± 74.620 nM) and 41.108 ± 10.180-271.171 ± 65.293 nM for hCA II (Ki value for standard inhibitor = 113.07 ± 20.980 nM) and significant antiproliferative activity with less toxicity to a health cell line. In addition, the theoretical parameters of the bioactive molecules were calculated to establish their drug-likeness qualities and ADME/T analysis was carried out to examine the drug properties of the synthesized compounds.
