MPP (1, 5, 10, 25, 50 and 100 μM; 24 h) decreases cell viability with an IC50 value of 20.01 μM in RL95-2 cells[1].
MPP dihydrochloride shows antiproliferative activity at a concentration of 10 μM in RL95-2 cells[1].
MPP dihydrochloride (20 μM; 24 h) reduces the phosphorylation of ERα, while it does not alter the phosphorylation of Akt. MPP dihydrochloride reduces the ratio of p-ERα/ERα[1].

-
Animal Model:Male C57BL/6N mice at the age of 9-10 weeks[2]
-
Dosage:Low dose (20 μg/kg body weight) or high dose (200 μg/kg body weight)
-
Administration:Administered subcutaneously (s.c.) injected; injection volume of 5 mL/kg; 60 min before PPI testing
-
Result:Led to a dose-dependent attenuation of percent PPI. Pretreatment with 200 μg/kg reduced the mean percent PPI scores by ~30%.
