CAII-IN-1 (compound 3n) is a thiosemicarbazide derivative that acts as a potent and selective inhibitor of carbonic anhydrase-II (CA-II), with an IC50 value of 10.3 μM for bovine CA-II. This compound (CAII-IN-1) finds utility in research pertaining to carbonic anhydrase-associated biological disorders [1].
CAII-IN-3 (compound 3h) is a thiosemicarbazone derivative known for its potent inhibition of carbonic anhydrase-II (CA-II). It exhibits an IC50 value of 13.4 μM [1].
Carbonic anhydrase inhibitor 14 (Compound 8b) is a potent CA inhibitor, exhibiting K i values of 1203, 99.7, 9.4, and 27.7 nM against hCA I, hCAII, hCA IX, and hCA XII, respectively. Additionally, it effectively inhibits CDK2 with an IC 50 of 20.3 μM. Furthermore, Carbonic anhydrase inhibitor 14 demonstrates significant antitumor activity [1].
