Inhibition of human carbonic anhydrase isozymes I, II and VI with a series of bisphenol, methoxy and bromophenol compounds

Abstract

Carbonic anhydrase inhibitors (CAI) are valuable molecules as they have several therapeutic applications, including anti-glaucoma activity. In this study, inhibition of three human carbonic anhydrase (hCA, EC 4.2.1.1) isozymes I, II and VI with a series of bisphenol and bromophenol derivatives was investigated. Molecular docking studies of a set of such inhibitors within CA I and II were also performed. K-I values of the molecules 2-9 were in the range of 10.025-892.109 mu M for hCA I, 1.437-59.107 mu M for hCA II and 11.143-919.182 mu M for hCA VI, respectively. Reported inhibitory activities of molecules 2-9 will assist in better understanding of structure-activity relationship studies of CAI.
