A series of sulfonamides was prepared by reaction of sulfanilamide with aryl/alkyl isocyanates. The ureido- substituted benzenesulfonamides showed a very interesting profile for the inhibition of several carbonic anhydrases (CAs, EC 4.2.1.1) such as the human hCA II and three beta-CAs from pathogenic fungal or bacterial species. The Candida albicans enzyme was inhibited with potencies in the range of 3.4-3970 nM, whereas the Mycobacterium tuberculosis enzymes Rv1284 and Rv3273 were inhibited with K(i)s in the range of 4.8-6500 nM and of 6.4-6850 nM, respectively. The structure-activity relationship for this class of inhibitors is rather complex, but the main features associated with effective inhibition of both a-and beta-CAs investigated here have been delineated. The nature of the moiety substituting the second ureido nitrogen is the determining factor in controlling the inhibitory power, probably due to the flexibility of the ureido linker and the possibility of this moiety to orientate in different subpockets of the active site cavities of these enzymes.

The use of dianhydrogalactitol provides a novel therapeutic modality for the treatment of non-small-cell lung carcinoma (NSCLC) and for the treatment of glioblastoma multiforme (GBM). Dianhydrogalactitol acts as an alkylating agent on DNA that creates N7 methylation. Dianhydrogalactitol is effective in suppressing the growth of cancer stem cells and is active against tumors that are refractory to temozolomide; the drug acts independently of the MGMT repair mechanism.
