A series of phosphorylated aromatic:heterocyclic sulfonamides with the general formula ArSO2NHPO3H2 have been prepared by condensing ArSO2NH2 with phosphorus pentachloride, Followed by controlled hydrolysis in the presence of formic acid. The new derivatives generally act as stronger inhibitors of two carbonic anhydrase (CA) isozymes, CA I and CA II, as compared to the parent unsubstituted sulfonamides from which they were obtained. The inhibition mechanism by this new class of CA inhibitors, as well as structure activity correlations for the series of investigated derivatives, are also discussed.
