dc.description.abstractBackground: The inhibition of both hydrolysis products of acetylcholine (ACh), Acetylcholinesterase (AChE) and Butyrylcholinesterase (BChE), is essential for successful treatment of Alzhemier patients. Objectives: This study was investigated inhibition potentials of recently synthesized disubstituted tacrines derivatives on going our research against AChE, BChE and carbonic anhydrase cyctosolic (hCA I and H) enzymes to explore the Structure activity relationship (SAR). Methods: Inhibitory activities of tested compounds against AChE and BChE were measured by spectrophotometric method, developed by Ellman et al. Furthermore, the disubstituted tacrines were determined as inhibitors of two physiologically relevant CA isoforms, the cytosolic hCA I and H by an esterase assay method. Results: The silyl, thiomethyl and cyano substituted seven membered hydrocycle tacrines (9, 11 and 14) significantly inhibited AChE, compared with starting compound 3 (6,8-dibromo-2,3,4,5-teytrahydro-1H-cyclohepta[1,2-b] quinoline) and reference compounds, galantamine and tacrine, while methoxy substituted seven membered hydrocycle tacrine derivative 10 showed selective inhibition against BChE (IC50 = 563 nM). Interestingly, disubstituted tacrines displayed higher or parallel inhibition to galantamine. Additionally, all these tacrine analogues were recorded to be powerful inhibitor compounds of the cytosolic isoenzyme hCA I with K-i in the range of 43.81-471.67 nM, as well as a moderate selectivity toward hCA II isoenzyme with K-i in the range from 87.14 to 614.68 nM compared with AZA, as standard. Conclusion: The disubstituted seven membered hydrocycle tacrine analogues 9-12 and 14 may have promising anti Alzhemier drug candidate and dibromo six membered hydrocycle 2 and dibromo seven membered hydrocycle 3 derivatives may be novel hCA I and II enzyme inhibitors.
