Compositions for the treatment of cancer comprising coumarin and thiocoumarin derivatives of Formulas I- XII are disclosed. Said derivatives preferentially inhibit carbonic anhydrase IX and XII (which are associated with hypoxic and metastatic tumours) over inhibiting carbonic anhydrase I and II activity. The compositions therefore are suited for treatment of hypoxic or metastatic cancers due to this selective mechanism of action.

Derivatized coumarin-based pharmaceutical compositions and methods to use them are provided. The compositions are characterized in that they inhibit the activity of tumor-related CAIX and CAXII to a greater degree than they inhibit the activity of CAI and CAII. The compositions can be used to suppress tumor growth and/or suppress tumor metastases in a mammal.

A series of coumarins incorporating tert-butyl-dimethylsilyloxy- or allyoxy- moieties in positions 4-, 6 or 7 of the heterocyclic ring have been synthesized and then converted to the corresponding 2-thioxocoumarins. Other derivatives incorporating hydroxyethyloxy-, tosylethoxy- and 2-fluroethyloxy-moieties in position 7 of the coumarin ring were synthesized together with derivatives of 4-methyl-7-amino coumarin incorporating acetamido, 3,5-dimethylphenylureido- and tert-butyloxycarbonylamido functionalities. All these compounds were assayed as inhibitors of the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1). The human (h) cytosolic isoforms hCA I and II were weakly inhibited (hCA I) or not inhibited at all (hCA II) by these (thioxo) coumarins whereas the tumor-associated transmembrane isoforms hCA IX and XII were inhibited with efficiencies from the submicromolar to the low micromolar range by many of these derivatives. The structure-activity relationship for these classes of less investigated CA inhibitors are delineated, with the potential of using them as leads to obtain isoform-selective inhibitors with excellent affinity for CA IX and XII (validated antitumor targets) which do not significantly inhibit the cytosolic offtarget isoforms hCA I and II.
