The new 1-(4-(3-(aryl)acryloyl)phenyl)-1H-pyrrole-2,5-diones (5a–g) were prepared from 4′-aminchalcones (3a–g) and screened for biological activities. All compounds (3a–g and 5a–g), except 3d and 3e displayed good cytotoxic activities with IC50 values in the range of 7.06–67.46 μM. IC50 value of 5-fluorouracil (5-FU) was 90.36 μM. Moreover, most of compounds 5a–g showed high antibacterial activity with 8–20 mm of inhibition zone (19–25 mm of Sulbactam-Cefoperazone (SCF)). In addition, they showed good inhibitory action against acetylcholinesterase (AChE), and human carbonic anhydrase I, and II (hCA I and hCA II) isoforms. Also, these compounds demonstrated effective inhibition profiles with Ki values of 426.47–699.58 nM against hCA I, 214.92–532.21 nM against hCA II, and 70.470–229.42 nM against AChE. On the other hand, acetazolamide, clinically used drug, showed a Ki value of 977.77 ± 227.4 nM against CA I, and 904.47 ± 106.3 nM against CA II, respectively. Also, tacrine inhibited AChE showed a Ki value of 446.56 ± 58.33 nM.
