Ag(I)NHC complexes were characterized using various spectroscopic and analytical techniques, including FTIR, NMR, and elemental analysis. The single crystal structures of the complexes <b>1e</b> and <b>1g</b> were illuminated through x-ray crystallography. The study demonstrates that the geometrical characteristics of both complexes closely match those of previously described complexes with a comparable ligand structure. Acetylcholinesterase (AChE) inhibitors prevent the excessive breakdown of acetylcholine by acting on acetylcholinesterase in its neurotransmission. In this way, they help to improve cognitive functions in patients with AD. On the other hand, human carbonic anhydrase inhibitors (CAIs) have been used clinically for many years as antiepileptic, antiglaucoma, antimetastatic, antitumor, and diuretic agents. In this study, the enzyme inhibition abilities of seven imidazol-2-ylidene-silver(I) complexes bearing 4-acetylphenyl side arm were examined against AChE and hCAs. These molecules exhibited a highly potent inhibition effect on AChE and hCAs (K<sub>i</sub> values are in the range of 16.27 ± 1.81 to 130.79 ± 11.98 nM for AChE, 13.22 ± 1.88 to 182.14 ± 33.93 nM for hCA I, and 12.72 ± 1.99 to 62.36 ± 9.21 nM for hCA II).
