Item Novel sulfonamides bearing pyrrole and pyrrolopyrimidine moieties as carbonic anhydrase inhibitors: Synthesis, cytotoxic activity and molecular modeling(Elsevier, 2014-11) Ghorab, Mostafa M.; Ceruso, Mariangela; Alsaid, Mansour S.; Nissan, Yassin M.; Arafa, Reem K.; Supuran, Claudiu T.Novel sulfonamides bearing pyrrole and pyrrolopyrimidine moieties as carbonic anhydrase inhibitors: synthesis, cytotoxic activity and molecular modeling المؤلفون Mostafa M Ghorab, Mariangela Ceruso, Mansour S Alsaid, Yassin M Nissan, Reem K Arafa, Claudiu T Supuran تاريخ النشر 2014/11/24 مجلة European journal of medicinal chemistry المجلد 87 الصفحات 186-196 الناشر Elsevier Masson الوصف Novel pyrrole and pyrrolopyrimidine scaffold-based sulfonamides were designed and synthesized. The carbonic anhydrase (CA) inhibition ability of all derivatives was assessed against the human (h) cytosolic isoforms hCA I and II and the transmembrane, tumor-associated isoforms hCA IX and XII. Some of these sulfonamides were 6–8 fold more potent than the reference drug acetazolamide (AZA, Ki = 5.7 nM)) against hCA XII showing subnanomolar activity. The in vitro cytotoxicity of these derivatives was evaluated against MCF-7, where some derivatives were more cytotoxic than doxorubicin (IC50 = 8.02 μM) displaying IC50 values between 6.46 and 7.56 μM. Docking of these sulfonamides with CA XII was performed and their binding modes were comparable with that of AZA.
