Biological Activity

Description Dydrogesterone (NSC 92336) is an orally active progestogen which acts directly on the uterus, producing a complete secretory endometrium in an estrogen-primed uterus.
progestogen Receptor [1]
In vitro

Dydrogesterone alone or in combination with estrogen to endothelial cells results in neutral effects on NO synthesis and on the activity and expression of eNOS. [1]

In vivo Dydrogesterone abrogates stress-triggered increase of the abortion rate in mice. Dydrogesterone restores the percentage of CD8+ uterus cells back to levels seen in control mice. Dydrogesterone significantly lowers the relative number of TNF-α-producing uterine cells on days 7.5, 9.5, and even on 10.5 in mice. Dydrogesterone results in significantly higher percentages of pregnancy protective IL-4+ uterus cells beginning on gestation day 7.5 and, even more strikingly, maintained until day 10.5 in stressed mice. [2] Dydrogesterone abrogates the highly elevated abortion rate of the abortion rate in mice exposured to sound stress. Dydrogesterone increases levels of plasma PIBF in stressed mice, but does not affect progesterone levels. Dydrogesterone dramatically increases the percentage of IL-4 positive decidual immune cells in stressed mice. [3]

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.
