A series of benzimidazo[1,2-c][1,2,3]thiadiazole-7-sulfonamides were synthesized and their binding to two carbonic anhydrase isozymes measured by isothermal titration calorimetry (ITC). Human carbonic anhydrase I (hCAI) and bovine carbonic anhydrase 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。
