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].
