General description

Methyl-piperidino-pyrazole hydrate (MPP) is prepared from a methyl-pyrazole-triol (MPT), a pyrazole triol.

Application

MPP dihydrochloride hydrate has been used as an estrogen receptor α antagonist:
  • in human breast cancer MCF-7 cells
  • to pre-treat endometrial ex vivo organ cultures (EVOCs)
  • to treat pituitary glands to monitor luteinizing hormone secretion

Biochem/physiol Actions

MPP dihydrochloride is a specific estrogen receptor α antagonist.
Methyl-piperidino-pyrazole hydrate (MPP) is an agonist for estrogen receptor α and lacks any ligand functionality with estrogen receptor (ER)β. It promotes silibinin induced apoptosis in human breast cancer MCF-7 cells.
