Biological Activity

Description Spironolactone is a potent antagonist of the androgen receptor with IC50 of 77 nM.
Targets
Androgen Receptor [1]
77 nM
In vitro

Spironolactone is a strong AR antagonist (IC50 ~ 77 nM), a weak GR antagonist (IC50 ~ 2.4 μM), and a weak PR agonist (EC50 ~ 740 nM). [1] Spironolactone inhibits androstanolone binding in rat prostate nuclei and androstanolone specific binding in rat prostate cytosol. [2]

In vivo Spironolactone (1 mg/day) exerts anti-androgenic activity in rats. A single pretreatment of spironolactone (1 mg/rat) inhibits specific and saturable uptake of hormone into prostate induced by tracer dose administration of [3H]testosterone. [2]

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.
