Solubility (25°C)* In vitro DMSO 77 mg/mL (200.77 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5% DMSO 95% corn oil
0.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 10 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL PEG300, mix evenly to clarify it; add 50 μL Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Brinzolamide (AL-4862) is a potent carbonic anhydrase II inhibitor with IC50 of 3.19 nM.
Targets
CAII [1]
3.19 nM
In vivo Brinzolamide (< 1 mg) ophthalmic suspension lowers intraocular pressure in Dutch-belted pigmented rabbits in a dose-dependent manner with an onset within 0.5 hour and a peak response by 1–2 hours. Brinzolamide (0.6 mg) ophthalmic suspension lowers intraocular pressure in laser-treated glaucomatous cynomolgus monkeys in a dose-dependent manner with an onset within 1 hour and a peak response by 3 hours. Brinzolamide dosages of 30 mg/kg, produces a 44% reduction in intestinal charcoal meal progression, but 1 and 10 mg/kg produced 8% and 18% decreases, respectively, in male CD-1 mice. Brinzolamide of 1 mg/kg, 10 mg/kg, and 30 mg/kg prolongs barbiturate sleep time by 57%, 15%, and 35%, respectively, in male CD-1 mice. [1] Brinzolamide (< 3%) produces significantly greater mean percent intraocular pressure reductions and mean intraocular pressure reductions compared with placebo in patients with primary, open-angle glaucoma or ocular hypertension. The optimal intraocular pressure-lowering concentration of brinzolamide is 1%, brinzolamide 1% is well tolerated by patients with primary open-angle glaucoma or ocular hypertension when administered twice daily. [2] Brinzolamide significantly decreases intraocular pressure and arteriovenous passage time compared with placebo in healthy volunteers. [3] Brinzolamide (2%) increases optic nerve head blood flow and decreases intraocular pressure in tranquilized Dutch-belted rabbits. [4] Brinzolamide (1%) reduces intraocular pressure by reducing aqueous flow and not by affecting aqueous humor drainage in normotensive eyes of rabbits and hypertensive eyes of monkeys. [5]
