Human carbonic anhydrase VII (hCA VII) is a cytosolic member of the alpha-CA family. This enzyme is mainly localized in a number of brain tissues such as the cortex, hippocampus and thalamus and has been noted for its contribution in generating neuronal excitation and seizures. Recently, it has been also proposed that hCA VII may be involved in the control of neuropathic pain, thus its inhibition may offer a new approach in designing pain killers useful for combating neuropathic pain. We report here the X-ray crystallographic structure of a mutated form of human CA VII in complex with acetazolamide, a classical sulfonamide inhibitor. These crystallographic studies provide important implications for the rational drug design of selective CA inhibitors with clinical applications.

A series of novel benzene sulfonamides (previously evaluated as selective cyclooxygenase-2 inhibitors) has been profiled against human carbonic anhydrases I, II, IV and VII in an attempt to observe the manifestation of the well established "tail" approach for designing potent, isoform-selective inhibitors of carbonic anhydrases (CAs, EC 4.2.1.1). The compounds displayed an excellent (pKi 7-8) inhibitory profile against CA II (a cytosolic anti-glaucoma and anti-edema biological target) and CA VII (also a cytosolic target believed to be involved in epilepsy and neuropathic pain) and a marked (1-2 orders of magnitude) selectivity against cytosolic isoform CA I and membrane-bound isoform CA IV. The separation of the CA II and CA IV (both of which are catalytically active isoforms, highly sensitive to sulfonamide-type inhibitors) is particularly remarkable and is adding significantly to the global body of data on the chemical biology of carbonic anhydrases.

Herein we report for the first time an efficient synthetic procedure for the preparation of N-aryl-N'-ureido-O-sulfamates (AUSs) as a new class of Carbonic Anhydrase Inhibitors (CAIs). The compounds were tested for the inhibition of several human (h) Carbonic Anhydrase (CA; EC 4.2.1.1) isoforms. Interesting inhibition activity and high selectivity against CA VII and XII versus CA I and II, with KIs in the low nanomolar range, were observed. Molecular modeling studies allowed us to decipher the structural features underpinning the selective inhibitory profile of AUSs towards isoforms CAs VII and XII. A selection of sulfamates showed promising neuropathic pain modulating effects in an in vivo animal model of oxaliplatin induced pain.
