Biological Activity

Description Methazolamide (CL 8490) is a carbonic anhydrase inhibitor with Ki of 50 nM, 14 nM and 36 nM for hCA I, hCA II and bCA IV isoforms, respectively.
Targets
hCAII [1] bCAIV [1] hCAI [1]
14 nM(Ki) 36 nM(Ki) 50 nM(Ki)
In vitro Methazolamide is a carbonic anhydrase inhibitor with Ki of 50 nM, 14 nM and 36 nM for hCA I, hCA II and bCA IV isoforms, respectively. [1] Methazolamide is of strength equal to acetazolamide, another carbonic anhydrase inhibitor used to treat irregular breathing disorders. However, methazolamide differs from acetazolamide in that it fails to activate Ca2+-dependent potassium channels in skeletal muscles. [2]
In vivo Methazolamide does not impair respiratory work performance in anesthetized rabbits. [2]
Features Methazolamide potently inhibits various isoforms of carbonic anhydrase.
