Biological Activity for PPT

PPT is a potent, subtype-selective estrogen receptor agonist (EC50 ~ 200 pM); displays 410-fold selectivity for ERα over ERβ. Prevents ovariectomy-induced weight gain and loss of bone mineral density, and induces gene expression in the hypothalamus following systemic administration in vivo.

Estrogen Signaling Pathway

Estrogen Signaling Pathway

Estrogen is a steroid hormone that is responsible for the regulation of growth, differentiation and function of the reproductive system. Estrogen signaling is often dysregulated in breast cancer and osteoporosis.
