With the aim to develop potent and selective human carbonic anhydrase inhibitors (hCAIs), we synthesized 4-sulfamoylphenyl/sulfocoumarin benzamides (series 5 a–r and series 7 a–q) and evaluated their inhibition profiles against five isoforms of the zinc-containing human carbonic anhydrase (hCA, EC 4.2.1.1): cytosolic hCA I and II, and the transmembrane isozymes hCA IV, IX, and XII. Compounds 5 a–r were found to selectively inhibit hCA II in the nanomolar range, while being less effective against the other hCA isoforms. As noted from the literature, sulfocoumarin (1,2-benzoxathiine 2,2-dioxide) acts as a “prodrug” inhibitor and is hydrolyzed by the esterase activity of hCA to form 2-hydroxyphenylvinylsulfonic acid, which thereafter binds to the enzyme in a manner similar to that of coumarins and sulfoxocoumarins. All these sulfocoumarins (compounds 7 a–q) were found to be very weak or ineffective as inhibitors of the housekeeping off-target hCA isoforms I and II, and effectively inhibited the transmembrane tumor-associated isoforms IX and XII in the high nanomolar to micromolar ranges. Further structural modifications of these molecules could be useful for the development of effective hCA inhibitors used for the treatment of glaucoma, epilepsy, and cancer.

A high-throughput screening campaign resulted in the discovery of a highly potent dual cannabinoid receptor 1 (CB1) and 2 (CB2) agonist. Following a thorough SAR exploration, a series of selective CB2 full agonists were identified.
