 Use of Benzolamide


Benzolamide (CL11366) is a potent carbonic anhydrase (CA) inhibitor, with Kis of 15 nM, 9 nM, 94 nM and 78 nM for hCA I, hCA II, EcoCAγ and VchCAγ, respectively. Benzolamide also inhibits CAS3, with a Ki of 54 nM. Benzolamide can be used for the research of glaucoma and seizures[1][2][3].

Ki: 15 nM (hCA I), 9 nM (hCA II), 94 nM (EcoCAγ), 78 nM (VchCAγ), 54 nM (CAS3)[1][2]

In Vitro Benzolamide inhibits hCA I, hCA II, EcoCAγ and VchCAγ, with Kis of 15 nM, 9 nM, 94 nM and 78 nM, respectively[1]. Benzolamide shows selectivity for CAS3 (Ki=54 nM) over CAS1 (Ki=2115 nM) and CAS2 (Ki=410 nM)[2].
In Vivo Benzolamide (90 µmol/kg; i.p.) decreases brain pH and suppresses electrographic post-asphyxia seizures in rats[3]. Animal Model: Male and female Wistar Han rats (11-day-old)[3] Dosage: 90 µmol/kg Administration: A single i.p. Result: Induced a fast brain acidosis of a comparable magnitude. Suppressed electrographic seizures after asphyxia by slowing down the recovery of brain pH.
