Molecular Weight 222.25 CAS No. 59-66-5
Solubility (25°C)* In vitro DMSO 44 mg/mL (197.97 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
2.2mg/ml Taking the 1 mL working solution as an example, add 50 μL of 44 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 95% Corn oil
0.73mg/ml Taking the 1 mL working solution as an example, add 50 μL of 14.6 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. 
* <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 Acetazolamide (Diamox), a potent carbonic anhydrase (CA) inhibitor, is commonly used in clinical practice as an immediate and readily available option for acute reduction of intraocular pressure(IOP).
Targets
Carbonic anhydrase [4]
10 nM
In vitro acetazolamide reduces invasiveness of cancer cells in vitro[3].
In vivo Acetazolamide reduces inflammation-induced heat hyperalgesia, probably acting both peripherally and centrally[1]. Acetazolamide shows significant inhibitory effect on angiogenesis in CAM and endothelial cell proliferation[2]. Acetazolamide is clinically used to reduce intraocular pressure in glaucoma, to correct metabolic alkalosis, and to manage cerebral edema. Its treatment may also be beneficial as an adjunct to cancer chemotherapy, because it can produce additive tumor growth delays with anticancer drugs in vivo[3].

Protocol (from reference)

Cell Assay:

[3]
  • Cell lines

    renal carcinoma cell lines(Caki-1, Caki-2, ACHN, and A-498)

  • Concentrations

    10 μM

  • Incubation Time

    48 h

  • Method

    The invasion assay is performed in a Biocoat Matrigel invasion chamber. Cells (n = 1.8 × 105) are added to the chamber and cultured for 48 h in the presence or absence of acetazolamide, which was administered twice during the 48-h period: the first dose at the beginning of the assay and the second after 24 h. After growing for 48 h, noninvasive cells are removed from the upper surface of the membrane with a cotton swab. The invasive cells on the lower surface of the membrane are fixed with 4% (vol/vol) neutral-buffered formaldehyde, stained with toluidine blue, and counted in 20 separate areas with a Leitz Diaplan microscope.
Animal Study:

[1]
  • Animal Models

    Male Sprague-Dawley rats

  • Dosages

    10, 100, 200 mg/kg

  • Administration
