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.

Mechanism of Action

Targets/IC₅₀/Ki	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]. This compound shows significant inhibitory effect on angiogenesis in CAM and endothelial cell proliferation^[2]. It 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].
