Applications : This is an impurity of Medroxyprogesterone, which is a synthetic form of human progesterone that acts as an agonist at progesterone receptors and can be taken orally. It promotes cell proliferation via the PI3K/Akt signaling pathway and has been shown to inhibit atherosclerosis in mice. However, its progesterone agonist activity is less potent compared to medroxyprogesterone acetate.
