[EN] The invention is related to novel compounds - benzimidazo[1,2-c][1,2,3]thiadiazole sulfonamides, corresponding to the general formula (I). The compounds can be used in biomedicine as active ingredients in pharmaceutical formulations, because they inhibit enzymes which participate in disease progression such as glaucome. The compounds of formula (I) inhibits enzymes such as carbonic anhydrases and metallo proteinases. This invention is also related to new intermediate compounds which are used for the synthesis of sulfonamides of formula (I). [FR] La présente invention concerne des composés innovants de benzimidazo[1,2-c][1,2,3]thiadiazole sulfamides, correspondant à la formule générale (I). (I) Les composés peuvent être utilisés en bio-médecine en tant que matière active dans des formulations pharmaceutiques parce qu'ils inhibent des enzymes qui participent à la progression d'une maladie telle que le glaucome. Les composés de formule (I) inhibent des enzymes telles que les anhydrases carboniques et les métallo-protéinases. L'invention concerne également des nouveaux composés intermédiaires qui sont utilisés pour la synthèse des sulfamides de formule (I).
Benzimidazo[1,2-c][1,2,3]thiadiazole-7-sulfonamides as inhibitors of carbonic anhydrase
A series of benzimidazo[1,2-c][1,2,3]thiadiazole-7-sulfonamides were synthesized and their binding to two carbonicanhydrase isozymes measured by isothermal titration calorimetry (ITC). HumancarbonicanhydraseI (hCAI) and bovine carbonicanhydrase II (bCAII) bound the inhibitors with observed association constants in the range from 1.1 x 10(6) to 2.6 x 10(7) M(-1).
合成了一系列苯并咪唑并[1,2-c] [1,2,3]噻二唑-7-磺酰胺,并通过等温滴定量热法(ITC)测定了它们与两种碳酸酐酶同工酶的结合。人碳酸酐酶I(hCAI)和牛碳酸酐酶II(bCAII)以观察到的缔合常数在1.1 x 10(6)至2.6 x 10(7)M(-1)范围内结合抑制剂。
