We describe the synthesis of a series of thiadiazolyl-benzenesulfonamide derivatives carrying an aromatic tail linked by an amide linker (12–34), as human carbonic anhydrase (hCA) inhibitors. These thiadiazol derivatives were evaluated against four physiologically relevant CA isoforms (hCA I, II, IX, and XII), and demonstrated intriguing inhibitory activity against CA II with Ki values in the range of 2.4–31.6 nM. Besides hCA II, also hCA XII activity was potently inhibited by some of the derivatives (Ki=1.5–88.5 nM), producing dual inhibitors of both isoforms. Notably, compound 17 was the most potent dual CA II (Ki=3.1 nM) and XII (Ki=1.5 nM) inhibitor with a significant selectivity ratio over CA I and IX isoforms. In conclusion, although all compounds exhibited preferential activity towards hCA II, the nature of the substituents at the tail part of the main scaffold influenced the activity and selectivity toward other isoforms.

A novel series of N-sulfonyl homoserine lactone derivatives 7a–7m has been designed, synthesized, and evaluated for quorum sensing inhibitory activities through the violacein inhibition in Chromobacterium violaceum CV026. Compound 7e displayed the high level of inhibitory activity among all the compounds synthesized. Studies of structure-activity relationship indicated that compounds with thiophene group in side chain showed better activity than those substituted by furan, pyrrole, pyridyl, and phenethyl group. Thiophene substituted compounds which connected electron withdrawing group exhibited better inhibitory activity relate to those connected electron donating group. Further analysis indicated that compound bearing an electron withdrawing substituent at the position 2 of their thiophene ring exhibited superior activity against violacein production to those bearing the substituent at the position 3 and 4. Compound 7e in particular, with IC50 value of 6.19 μM, were identified as promising lead compounds for further development.
