Biological Activity

[Description]:

Propyl pyrazole triol (PPT) is an estrogen receptor alpha (ERσ) agonist. The relative binding affinity of Propyl pyrazole triol for ERα (ERα: 49%) around 410 times higher compared with estrogen receptor beta (ERβ: 0.12%)[1].

Research Areas >> Cancer

[Target]

Estrogen receptor alpha[1]

[In Vitro]

The EC50 of Propyl pyrazole triol for the ERα-dependent response is 140 pM in ERα-U2OS-Luc cells[1].
