progesterone-d9 CAS Number

Progesterone-d9 is a stable isotope-labeled derivative of progesterone, an endogenous steroid hormone that acts as a potent agonist of the nuclear progesterone receptor. Upon ligand binding, activated progesterone receptor signaling regulates complex gene expression networks essential for uterine receptivity, embryo implantation, and maintenance of pregnancy, while orchestrating cellular proliferation and tissue differentiation across female reproductive systems. ^[1]
