Atropo/Tropo Flexibility: A Tool for Design and Synthesis of Self-Adaptable Inhibitors of Carbonic Anhydrases and Their Antiproliferative Effect. J.Med.Chem., 66:5703-5718, 2023 Cited by PubMed Abstract: Here, we report for the first time a series of sulfonamide derivatives with scaffolds bearing flexible moieties, namely, rotamers or tropoisomers capable of adapting their geometry in the active center of enzymes thus being effective and selective carbonic anhydrase (CAs, EC 4.2.1.1) enzyme inhibitors. All compounds exhibited effective in vitro inhibition activity toward the main hCA isoforms related to cancer (i.e., hCA II, hCA IX, and hCA XII with values in the low nanomolar range). Three selected compounds showed a great cytotoxic effect on cancer cell lines ex vivo. X-ray crystallographic experiments assessed the binding modes of compound with active centers of hCA IX and hCA XII.
