hCAI II-IN-2 (compound 2b) is a highly effective dual inhibitor of human carbonic anhydrase I and II (hCA I II), with Ki values of 40.97 nM, 15.15 nM, and 61.88 nM for hCA I, hCA II, and hCA IX, respectively. With its anti-hypoxic properties, hCAI II-IN-2 demonstrates activity against acute mountain sickness (AMS). Furthermore, this compound exhibits low cellular activity [1].
hCAI II-IN-4 (compound 6d) is a powerful inhibitor of both hCA I and hCA II enzymes, with Ki values of 16.95 nM and 15.22 nM, respectively. It demonstrates inhibitory activity against hCA IX with a Ki value of 27.04 nM. Additionally, hCAI II-IN-4 exhibits anti-hypoxia properties while maintaining low toxicity. This compound is suitable for investigating acute mountain sickness (AMS) in research studies [1].
hCAI II-IN-3 (compound 5b) is a highly effective dual inhibitor of hCA I II enzymes. It exhibits Ki values of 51.25, 13.15, and 42.18 nM for hCA I, hCA II, and hCA Ⅸ, respectively. hCAI II-IN-3 demonstrates anti-hypoxic properties against acute mountain sickness (AMS) and exhibits low cellular activity [1].
hCAII-IN-3 (Compound 16) is an inhibitor of human carbonic anhydrase (hCA). It exhibits high affinity for hCA I, hCA II, hCA IX, and hCA XII, with Ki values of 403.8 nM, 5.1 nM, 10.2 nM, and 5.2 nM, respectively. Notably, hCA IX-IN-2 demonstrates anticancer activity [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, hCA II, 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].
