The best hCA I and II inhibitor was biphenyl boronic acid with, a K (I) of 3.7-4.5 microM, whereas the remaining derivatives showed inhibition constants in the range of 6.0-1560 microM for hCA I and of 6.0-1050 microM for hCA II, respectively. hCA IX and XII were effectively inhibited by most of the aromatic boronic acids (K (I) s of 7.6-12.3 microM) whereas the arylalkenyl and aryl-alkyl derivatives generally showed weaker inhibitory properties (K (I) s of 34-531 microM).

Reaction of 4,4-biphenyl-disulfonyl chloride with aromatic/heterocyclic sulfonamides also incorporating a free amino group, such as 4-aminobenzenesulfonamide, 4-aminoethyl-benzenesulfonamide, 6-chloro-4-aminobenzene-1,3-disulfonamide or 5-amino-1,3,4-thiadiazole-2-sulfonamide afforded bis-sulfonamides which have been tested as inhibitors of the zinc enzyme carbonic anhydrase (CA, EC 4..2.1.1).

We found that extensive neuronal death occurred in the cortex and the CA1 area of the hippocampus at day 7 after IR and that bicyclol significantly attenuated IR-induced neuronal death in a dose-dependent manner.

At 1 mg/kg po, 20 and 23 reduced plasma estradiol levels strongly and inhibited liver STS activity potently in vivo. 23 is nonestrogenic and potently inhibits carbonic anhydrase II (IC (50) 86 nM).
