  "abstract": "A series of novel hybrid [1,4]benzoxazepine-based sulfonamide derivatives 9–12a–j were synthesized and evaluated for their inhibitory activity against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Compounds 9a and 9b exhibited potent dual cholinesterase inhibition, with IC50 values of 9.04 and 8.61 µM against AChE and 3.08 and 4.64 µM against BChE, respectively. Compound 12j emerged as the most potent BChE inhibitor of the series (IC50 = 1.06 ± 0.11 µM), displaying pronounced BChE preference (SI = 10.37), whereas 9d showed the highest BChE selectivity (BChE IC50 = 4.18 ± 0.56 µM; SI = 14.94). Molecular docking studies revealed plausible binding modes of the active compounds within the AChE and BChE active sites, involving π–π stacking, hydrogen bonding, and hydrophobic interactions. The SAR analysis indicated that the effects of nitro and halogen substituents were scaffold- and position-dependent, with selected nitro-substituted derivatives showing enhanced cholinesterase inhibition, whereas brominated analogs exhibited a pronounced preference toward BChE. Integration of the biological and computational data identified compounds 9a, 9b, 9d, 12b, 12j, and 12j as promising candidates for further investigation. Among these, 12j represents the potency lead for BChE inhibition, whereas 9d provides the most pronounced BChE selectivity. ADMET predictions further suggested more favorable physicochemical and pharmacokinetic profiles for selected benzoxazepine-based derivatives, although potential toxicity liabilities were predicted for 12j. Overall, these findings support the [1,4]benzoxazepine–sulfonamide scaffold as a promising starting point for developing BChE-preferring cholinesterase inhibitors.",
