    Product Description

    DPPE is a ligand for the antiestrogen-binding site (AEBS; Ki = 55.6 nM in rat liver microsomes) and derivative of tamoxifen (Item No. 11629).1 It is selective for the AEBS over the estrogen receptor when used at a concentration of 10 µM. DPPE is cytotoxic to S10 and MCF-7 cells (IC50s = 7.5 and 12 µM) and inhibits antigen-induced histamine release in isolated rat mast cells (IC50 = 65-85 µM).2,3 It decreases uterine size in immature oophorectomized rats in a dose-dependent manner.4 DPPE (4 mg/kg) protects bone marrow progenitor cells from cytotoxicity induced by doxorubicin (Item No. 15007) in mice.2
