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.

The chemosignaling of widely used peracid oxidant of m-chloroperbenzoicacid (mCPBA) by the selective desulfurization of thiocoumarin was investigated. Thiocoumarin was efficiently converted into its corresponding coumarin by the reaction with mCPBA, and resulted in a pronounced fluorescent turn-on type signaling. The conversion also provided a significant change in absorption behavior which allowed
