Sulfonamide Derivatives Having Carbonic Anhydrase Inhibiting Activity and their Use as Therapeutic and Diagnostic Agents

摘要

The present invention discloses sulfonamide A-(Q)n—Ar—SChNHR which are CA IX-selective inhibitors, which selectively bind to the enzyme under hypoxic conditions and are able to reverse the tumor acidification mediated by the enzyme. These compounds are useful in anticancer therapies based on tumor-associated CA isozyme inhibition as well as for hypoxic tumor imaging.
