Sample solution is provided at 25 µL, 10mM.
MPP dihydrochloride is a selective estrogen receptor α (ERα) antagonist [1]. MPP dihydrochloride blocks estrogen signaling, thereby inducing cell apoptosis [2]. MPP dihydrochloride is used to treat cancer [3].
In MCF-7 cells, MPP dihydrochloride (5μM, 15μM, 20μM; 1h) treatment dose-dependently enhanced silibinin-induced growth inhibition of cells [4]. In SKOV3 cells, MPP dihydrochloride (20μM; 24h) treatment significantly increased the number of cells [5]. In SKOV3 and OV2008 Cells, MPP dihydrochloride (10pM, 100pM, 1000pM; 24h) treatment significantly inhibited cell growth in both cell lines [6]. In ectopic endometrial stromal cells (eESCs), MPP dihydrochloride (2.7nM; 48h) treatment increases the autophagy level in eESCs [7].
In SKOV3 cell subcutaneous tumor mice model, MPP dihydrochloride (1mg/kg; ip; 35d) treatments reduce in vivo tumor cell growth in mice [6]. In SERT+ mice, MPP dihydrochloride (2mg/kg; sc; 14d) attenuates the development of pulmonary hypertension (PH) in normoxic and hypoxic female SERT+ mice [8]. In C57/BL6 mice, MPP dihydrochloride (200μg/kg; ip; 7d) treatment significantly reduced the expression of rictor, p-AKT(Ser473)/AKT, p-cofilin (Ser3), and profilin-1 [9].
