Solubility (25°C)* In vitro DMSO 18 mg/mL (46.56 mM)
Ethanol 15 mg/mL (38.8 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 30%PEG300 5%Tween80 60%ddH2O
0.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 10 mg/ml clarified DMSO stock solution to 300 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 600 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description MPA (Medroxyprogesterone acetate) is a synthetic progestin and act as a potent progesterone receptor agonist, used to treat abnormal menstruation or irregular vaginal bleeding.
Targets
progestogen Receptor [1]
In vitro

Medroxyprogesterone acetate (MPA) inhibits the enzyme 3-hydroxyste-roid dehydrogenase, involved in the reversible conversion between 5alpha-dihydroprogesterone (DHP) and 3alpha, 5alpha-tetrahydroprogesterone (THP), and therefore may affect the local actions of DHP and THP in the brain. [1]

Medroxyprogesterone acetate (MPA) reduces secretion of IL-6 and PTHrP from human breast cancer cells. MPA dose-dependently decreases the secretion and mRNA expression of IL-6 and PTHrP in the KTC-2 cells. [2]

Medroxyprogesterone acetate (MPA) and dexamethasone dose dependently increases alpha-ENaC promoter-driven luciferase activity in M-1 cells, which is not inhibited by Org31710, indicating that Medroxyprogesterone acetate regulates alpha-ENaC in a PR-independent manner. Medroxyprogesterone acetate and dexamethasone, but not progesterone, dose dependently increases alpha-ENaC and sgk1 mRNA in M-1 and in Madin-Darby canine kidney-C7 cells, both collecting duct cell lines. [3]

Medroxyprogesterone acetate (MPA) (0.1 nM) significantly enhances the in vitro production of specific immunoglobulin G (IgG) antibodies, an effect that appears to involve the interaction of the progestin with PRG receptors[4]
In vivo

Medroxyprogesterone acetate (MPA) impairs delayed memory retention on the water radial-arm maze (WRAM), and exacerbates overnight forgetting on the Morris maze (MM) in aged ovariectomized (OVX) rats. Medroxyprogesterone acetate (MPA) significantly and progesterone marginally decreases GAD levels in the hippocampus, and both MPA and progesterone significantly increases GAD levels in the entorhinal cortex.
