Validado por los laboratorios Selleck. Si necesita ajustes en esta formulación, póngase en contacto con nuestro equipo de ventas para pruebas personalizadas.

 0.500mg/ml (1.29mM) 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 significa ligeramente soluble o insoluble.
* Tenga en cuenta que Selleck prueba la solubilidad de todos los compuestos internamente, y la solubilidad real puede diferir ligeramente de los valores publicados. Esto es normal y se debe a ligeras variaciones entre lotes.
* Envío a temperatura ambiente (Las pruebas de estabilidad demuestran que este producto se puede enviar sin medidas de refrigeración.)

Actividad biológica

Descripción El MPA (acetato de medroxiprogesterona) es un progestágeno sintético y actúa como un potente agonista del Progesterone Receptor, utilizado para tratar la menstruación anormal o el sangrado vaginal irregular.
Objetivos
progestogen Receptor
In vitro

Medroxyprogesterone acetate (MPA) inhibits the enzyme 3-hydroxysteroid 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.

It reduces secretion of IL-6 and PTHrP from human breast cancer cells. This compound dose-dependently decreases the secretion and mRNA expression of IL-6 and PTHrP in the KTC-2 cells.

MPA and dexamethasone dose dependently increase alpha-ENaC promoter-driven luciferase activity in M-1 cells, which is not inhibited by Org31710, indicating that it regulates alpha-ENaC in a PR-independent manner. This compound and dexamethasone, but not progesterone, dose dependently increase alpha-ENaC and sgk1 mRNA in M-1 and in Madin-Darby canine kidney-C7 cells, both collecting duct cell lines.

At 0.1 nM, it 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
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. It significantly and progesterone marginally decreases GAD levels in the hippocampus, while both MPA and progesterone significantly increase GAD levels in the entorhinal cortex.

Validación de productos por parte del cliente

The analgesic effect of koumine was reversed in sciatic nerve chronic constriction injury rats by intrathecal treatment with medroxyprogesterone acetate. Medroxyprogesterone acetate (MPA) or dimethyl sulfoxide (DMSO, vehicle) was administered via an intrathecal catheter 10 days after sciatic nerve chronic constriction injury (CCI) surgery. After 30 min, koumine (7 mg kg−1 bw) or normal saline (NS) was administered by subcutaneous (s.c.) injection. The mechanical withdrawal threshold (MWT) of the hind paws was measured 1 h after completion of the drug or vehicle administration. The data are presented as the mean ± SEM (n = 6 per group) and were analyzed by one-way ANOVA followed by Bonferroni post hoc test at each time point. *P < 0.05 vs. the DMSO + NS group; # P < 0.05 vs. the DMSO + koumine group.
