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
In vitro acetazolamide reduces invasiveness of cancer cells in vitro[3].
Cell Research 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.

In Vivo
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].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
