Biological Activity

Description	Desogestrel (Cerazette, Desogen, Desogestrelum, Org-2969) is a synthetic progestational hormone used often as the progestogenic component of combined oral contraceptive agents.

In Vivo
In vivo	Desogestrel is extensively metabolized after oral administration to rats and dogs; In rats, desogestrel is metabolized mainly at the C3, C5, C11, and C15 positions. An hydroxy group is introduced at the 15α-position of desogestrel, followed by conjugation with glucuronic acid. In dogs, desogestrel is mainly metabolized at the C3- and C17-positions^[1].
Animal Research	Animal Models	Female Wistar rats, Female beagle dogs
	Dosages	56 μg/kg, 106 mg/kg (Rats); 67 μg/kg, 9.6 mg/kg(Dogs)
	Administration	oral administration

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.
