Design, synthesis, and biological activity of novel dithiocarbamate‐methylsulfonyl hybrids as carbonic anhydrase inhibitors

Abstract Carbonic anhydrase (CA) enzymes are involved in many physiological events. These enzymes, which contain Zn 2+ in their structure, can be easily inhibited by dithiocarbamate compounds. In addition, CA enzyme inhibitory activities are known in groups such as sulfonamide and methylsulfonyl. For this purpose, in this study, a series of 23 new dithiocarbamate‐methylsulfonyl derivatives were synthesized and their CA enzyme inhibitory activities were investigated. The inhibition potentials of the obtained compounds against the human CA I and CA II enzymes were investigated by the in vitro enzyme isolation method. It is seen that the compounds show activity at the nanomolar level. Molecular docking studies of the compounds were carried out by in silico methods. The poses of compounds 2a , 2e , 2o , and 2t are presented.
