Sulfonamide CA inhibitors are used therapeutically as diuretic, antiglaucoma, antiobesity and anticancer agents. A series of new sulfonamides were synthesized using imides and tosyl chloride as starting materials. These N-acylsulfonamides efficiently inhibited the cytosolic human carbonic anhydrase isoenzymes I, and II (hCA I, and II), with nanomolar range inhibition constants ranging between 36.4 ± 6.0-254.6 ± 18.0 and 58.3 ± 0.6-273.3 ± 2.5 nM, respectively.</dc:description><dc:publisher>Elsevier Ltd</dc:publisher><dc:date>2015</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/gumushane/15391</dc:identifier><dc:identifier>https://doi.org/10.1016/j.bmc.2014.12.054</dc:identifier><dc:identifier>0968-0896</dc:identifier><dc:language>en</dc:language><dc:relation>Bioorganic and Medicinal Chemistry</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/15391</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
