additional information | development and synthesis of a series of compounds incorporating regioisomeric phenylethynylbenzenesulfonamide moieties, analysis of potential as inhibitors of the four human isozymes, hCA I, hCA II, hCA IX, and hCA XII. The position of the sulfamoyl group with respect to the alkyne functionality, and the nature of the moieties substituting the second aromatic ring are the principal structural features influencing CA inhibition. The para-sulfamoyl-substituted derivatives are effective inhibitors of CA IX and XII, the meta-substituted regioisomers of CA I, X and XII, whereas the ortho-substituted sulfonamides ae weak inhibitors of CA I, II and IX, but inhibit ignificantly CA XII, structure-activity relationship study, overview | Homo sapiens | |
