Özet

Phenolic mono Mannich bases [2-[4-hydroxy-3-(aminomethyl) benzylidene]-2,3-dihydro-1H-inden-1-one (8-15)] and bis Mannich bases [2-[4-hydroxy-3,5-bis(aminomethyl) benzylidene]-2, 3-dihydro-1H-inden-1-one (2-7)] were synthesized starting from 2-(4-hydroxybenzylidene)-2, 3-dihydro-inden-1-one (1). This study was designed in order to investigate the carbonic anhydrase (CA, EC 4.2.1.1) inhibitory properties of a library of compounds incorporating the phenol functional group. All prepared compounds showed a low inhibition percentages on both human (h) isoforms hCA I and hCA II compared to the reference sulfonamide acetazolamide. Mannich bases 2-15 had lower inhibition percentages than the compound 1 on hCA I and hCA II, except compound 14, which is a Mannich base derivative of dipropylamine, which had a similar inhibitory power as compound 1 on hCA II. All compounds synthesized 1-15 were 1.3-1.9 times more effective on hCA II comparing with the effectivenes of the compounds on hCA I.
