Synthesis and investigation of anticancer, antibacterial activities and carbonic anhydrase, acetylcholinesterase inhibition profiles of novel (3aR,4S,7R,7aS)-2-[4-[1-acetyl-5-(aryl/heteroaryl)-4,5-dihydro-1H-pyrazol-3-yl]phenyl]-3a,4,7,7a-tetrahydro-1H-4,7-methanoisoindole-1,3(2H)-diones

Abstract

A series of novel 1,3,5-trisubstituted pyrazoline derivatives, (3aR,4S,7R,7aS)-2-[4-[1-acetyl-5-(aryl/heteroaryl)-4,5-dihydro-1H-pyrazol-3-yl]phenyl]-3a,4,7,7a-tetrahydro-1H-4,7-methanoisoindole-1,3(2H)-diones, were synthesized and evaluated for their antimicrobial and anticancer activities. In addition, the compounds were tested against acetylcholinesterase (AChE) enzyme and two physiologically relevant carbonic anhydrase I and II isozymes (hCA I and II). In this study, inhibition of hCA I and hCA II by the novel synthesized 1,3,5-trisubstituted pyrazolines was impressive, with K-i values in the range of 3.33-7.90nM for hCA I and 2.07-8.47nM for hCA II, while the K-i values of these compounds for AChE were recorded in the range of 9.61-48.42nM, respectively. Two compounds can be investigated as the leader compounds because of their lowest K-i values to make further detailed CA inhibition studies.
