Biological Activity

Description

Ethisterone(17α-Ethynyltestosterone) is a progestogen hormone being considered to treat prostate cancer.

Targets

progestogen Receptor ^[1]

In Vivo
In vivo	Ethisterone (dose range: 40 μg-5 mg/day × 6) stimulates weight gain but has a rather weak effect on the sulphate pools and incorporation rates in mice. ^[1] Ethisterone results in rapid increases in labeling indexes and scleroblast population began simultaneously in the central portion in the posterior margin of the joint plate in adult females of the medaka, Oryzias latipes, and the population becomes approximately ten times that in the control fish on the fifth day. ^[2]

Calculation results:

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.
