All the synthesized compounds were evaluated for their in vitro carbonic anhydrase (CA, EC 4.2.1.1) inhibitory effects against the human (h) isoforms hCA I, II, IX and XII. Among the tested derivatives, compounds 16, 18 and 20–24 showed potent activity as inhibitors for the tumor associated transmembrane isoforms (hCA IX and XII) in the nanomolar and subnanomolar range, with high selectivity. All compounds underwent cytotoxic activity assays on human breast cancer cell line (MCF-7) showing effective activity, comparable to that of the clinically used drug doxorubicin

    Novel sulfonamides bearing pyrrole and pyrrolopyrimidine moieties as carbonic anhydrase inhibitors: Synthesis, cytotoxic activity and molecular modeling

    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.
