The acid catalyzed hydrolysis of the N-(p-substitutedphenyl) phthalimides in three different acids was investigated at 50.0±0.1°C. Two different antioxidant activity tests as DPPH• and ABTS•+ scavenging activities, and three various enzyme inhibition activity tests as urease, acetylcholinesterase (AChE), and butyrylcholinesterase (BChE) inhibition activities, were applied. Compound 3c (2.03 µg/mL ) has higher antioxidant activity than other compounds and standards according to DPPH test. In AChE assay, compounds 3a and 3b (13.13 and 9.59 µg/mL) has higher enzyme inhibition activity than the standard Galantamine (14.37 µg/mL). In BChE and urease tests, all compounds (6.84-13.60 and 10.49-17.73 µg/mL) have higher enzyme inhibition activity than the standard Galantamine (49.40 µg/mL) and thiourea (26.19 µg/mL), respectively. The molecule interaction for each of the three compounds with the active sites of AChE, BChE, and urease enzymes was examined via molecular docking simulations.
