A novel series of benzenesulfonamide derivatives of barbituric and thiobarbituric acids (2-12) were synthesized by condensation and cyclization reactions of various ureido and thioureido derivatives of sulfanilamides. Different substituents have been inco

A series of ureido-substituted benzenesulfonamides was prepared that showed a very interesting profile for the inhibition of several human carbonic anhydrases (hCAs, EC 4.2.1.1), such as hCAs I and II (cytosolic isoforms) and hCAs IX and XII (transmembrane, tumor-associated enzymes). Excellent inhibition of all these isoforms has been observed with various members of the series, depending on the substitution pattern of the urea moiety. Several low nanomolar CA IX/XII inhibitors also showing good selectivity for the transmembrane over the cytosolic isoforms have been discovered. One of them, 4-{[(3′- nirophenyl)carbamoyl]amino}benzenesulfonamide, significantly inhibited the formation of metastases by the highly aggressive 4T1 mammary tumor cells at pharmacologic concentrations of 45 mg/kg, constituting an interesting candidate for the development of conceptually novel antimetastatic drugs.
Carbonic anhydrase inhibitors - Part 49: Synthesis of substituted ureido and thioureido derivatives of aromatic/heterocyclic sulfonamides with increased affinities for isozyme I

Reaction of nine aromatic/heterocyclic sulfonamides containing a free amino group with aryl isocyanates/isothiocyanates or allyl isothiocyanate afforded the corresponding urea/thiourea derivatives, which were characterized by standard physico-chemical procedures and assayed as inhibitors of three isozymes of carbonic anhydrase (CA), i.e. hCA I, hCA II and bCA IV (h = human, b = bovine isozyme). Another series of compounds, 1,5-disubstituted-2-thiobiuret derivatives, were prepared by reaction of 3,4-dichlorophenyl isocyanate with thioureido-containing aromatic/heterocyclic sulfonamides. Good inhibition of all these three CA isozymes was observed with the new compounds, but an exciting finding was that the ureas/thioureas and especially the above-mentioned thiobiurets reported here have an increased affinity to the slow isozyme hCA I, generally less susceptible to inhibition by sulfonamides, as compared to the rapid isozymes hCA II and bCA IV. Some of the new compounds might constitute good lead molecules for developing more selective CA I inhibitors.
