Background

Medroxyprogesterone acetate(MPA) is a steroidal progestin, a synthetic variant of the human hormone progesterone. It is used as a contraceptive, in hormone replacement therapy and for the treatment of endometriosis as well as several other indications. MP

General tipsFor obtaining a higher solubility, please warm the tube at 37°C and shake it in the ultrasonic bath for a while. Stock solution can be stored below -20°C for several months.

Protocol

Cell experiment [1]:

Cell lines

M-1 cells

Preparation method

The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months.

Reacting condition

1 nM ~ 1 μM; 24 hrs

Applications

In M-1 cells, Medroxyprogesterone Acetate at the dose of 1 μM increased α-epithelial Na channel (α-ENaC) and serum and glucocorticoid-regulated kinase 1 (sgk1) expression. Medroxyprogesterone Acetate dose-dependently increased α-ENaC expression with the earliest effect seen at 10 nM. In Medroxyprogesterone Acetate-treated M-1 cells, α-ENaC-driven luciferase activity could not be inhibited by Org31710, which indicated that Medroxyprogesterone Acetate regulated α-ENaC in a progesterone receptor (PR)-independent manner.

Animal experiment [2]:

Animal models

Rats

Dosage form

14 and 21 mg/2 mL; given via osmotic pumps

Applications

In aged ovariectomized rats, Medroxyprogesterone acetate impaired delayed memory retention on the water radial-arm maze, and exacerbated overnight forgetting on the Morris maze. Medroxyprogesterone acetate significantly decreased the level of glutamic acid decarboxylase (GAD) in the hippocampus, and increased GAD level in the entorhinal cortex.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
