Biological Activity

Description Metyrapone (NSC-25265, SU-4885) is an inhibitor of the enzyme steroid 11-beta-monooxygenase (CYP11B1) that inhibits adrenal steroid synthesis.
Targets
11β-HSD1 [1]
30 μM(Ki)
In vitro
In vitro Metyrapone is a well known inhibitor of 11β-hydroxylase, a key enzyme involved in the final step of cortisol biosynthesis. At higher concentrations, it also inhibits other steroidogenic enzymes such as cholesterol side chain cleavage enzyme. It is specific for 11β-HSD1 while it has little effect on 11β-HSD2 activity[1].
In Vivo
In vivo The administration of metyrapone to man, and animals such as the dog and sheep thus leads to a decrease in circulating levels of cortisol[1].

Working concentration: mg/ml;

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.
