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.
