carbonic anhydrase inhibitor 10

Carbonic anhydrase inhibitor 10 can be used in the research of cancer that shows anti-proliferative activity against MCF-7 cancer cell line with an IC50 of 11.9 μM. Carbonic anhydrase inhibitor 10 is a potent inhibitor of h CA IX with a Ki value of 6.2 nM [1].

hCAI/II-IN-10 (Compound 5d) is an inhibitor of human carbonic anhydrase I and II (hCA I and hCA II), with IC50 values of 4.32 nM and 3.89 nM, respectively.

hCAIX/XII-IN-10 (compound DK-8) is an inhibitor of Carbonic Anhydrase, showing potent inhibitory activity against the tumor-associated membrane-bound isoforms hCA IX and XII, with Ki values of 32.5 nM and 29.2 nM, respectively.

ts-SA is a metalloenzyme carbonic anhydrase (CA) inhibitor. It is active against 7 out of 10 human CA isoforms.

Dichlorphenamide-13C6is intended for use as an internal standard for the quantification of dichlorphenamide by GC- or LC-MS. Dichlorphenamide is a sulfonamide and an orally bioavailable carbonic anhydrase (CA) inhibitor (Kis = 1.20, 38, 50, and 50 nM for the human CA isoforms CAI, CAII, CAIX, and CAXII, respectively).1It lowers intraocular pressure in rabbits when 50 μl of a 10% solution is applied topically to the eye.2Dichlorphenamide rescues the potassium deficiency and prevents insulin-induced paralysis in a rat model of familial hypokalemic periodic paralysis when administered at a dose of 5.6 mg/kg per day for ten days.3Formulations containing dichlorphenamide have been used in the treatment of glaucoma and primary periodic paralysis.

Zonisamide-13C2,15N is intended for use as an internal standard for the quantification of zonisamide by GC- or LC-MS. Zonisamide is an antiepileptic agent.1 It selectively inhibits the repeated firing of sodium channels (IC50 = 2 μg/ml) in mouse embryo spinal cord neurons and inhibits spontaneous channel firing when used at concentrations greater than 10 μg/ml.2 In rat cerebral cortex neurons, zonisamide (1-1,000 μM) inhibits T-type calcium channels with a maximum reduction of 60% of the calcium current.3 Zonisamide inhibits H. pylori recombinant carbonic anhydrase (CA) and the human CA isoforms I, II, and V with Ki values of 218, 56, 35, and 21 nM, respectively.4,5 In mice, it has anticonvulsant activity against maximal electroshock seizure (MES) and pentylenetetrazole-induced maximal, but not minimal, seizures (ED50s = 19.6, 9.3, and >500 mg/kg, respectively). Zonisamide (40 mg/kg, p.o.) prevents MPTP-induced decreases in the levels of dopamine , but not homovanillic acid or dihydroxyphenyl acetic acid , and increases MPTP-induced decreases in the dopamine turnover rate in mouse striatum in a model of Parkinson's disease.6 Formulations containing zonisamide have been used in the treatment of partial seizures in adults with epilepsy. |1.

hCAIX-IN-10 (Compound 6i) is a selective inhibitor of carbonic anhydrase IX and XII, targeting hCA IX (Ki: 61.5 nM) and hCA XII (Ki: 586.8 nM). hCA IX and hCA XII are transmembrane isoforms of carbonic anhydrase and serve as biomarkers for certain types of tumors, with hCA XII also playing a role in maintaining acid-base homeostasis in both normal and tumor cells.

Phenylsulfamide (Compound 10), acting as an inhibitor of human carbonic anhydrase-II (hCA-II), exhibits a dissociation constant (Kd) of 45.50 μM and an inhibition constant (Ki) of 79.60 μM [1].

hCAXII-IN-10 (Compound 18b) acts as a dual inhibitor of human carbonic anhydrase isoenzyme XII (hCAXII) and cathepsin B, with a Ki value of 2.2 nM. It inhibits the function of hCAXII in creating a pH microenvironment conducive to tumor growth, showing promise for use in cancer research.
