  2. Estrogen Receptor/ERR
  3. Methylpiperidino pyrazole

Methylpiperidino pyrazole (MPP) is a potent and selective ER (estrogen receptor) modulator. Methylpiperidino pyrazole induces significant apoptosis in the endometrial cancer and oLE cell lines. Methylpiperidino pyrazole reverses the the positive effects of beta-estradiol. Methylpiperidino pyrazole has mixed agonist/antagonist action on murine uterine ERalpha in vivo.

Description

Methylpiperidino pyrazole (MPP) is a potent and selective ER (estrogen receptor) modulator. Methylpiperidino pyrazole induces significant apoptosis in the endometrial cancer and oLE cell lines. Methylpiperidino pyrazole reverses the the positive effects of beta-estradiol. Methylpiperidino pyrazole has mixed agonist/antagonist action on murine uterine ERalpha in vivo[1][2][3].

In Vitro

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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[1]

Cell Line: RL95-2 endometrium cancer cells
Concentration: 1, 5, 10, 25, 50 and 100 µM
Incubation Time: 24 hours
Result: The treatment with 25 µM, 50 µM and 100 µM for 24 h decreased cell viability significantly. However, cell viability was not significantly changed by MPP dihydrochloride at concentration below 25 µM.

Cell Proliferation Assay[1]

Cell Line: RL95-2 cell
Concentration: 10, 15, 20 and 25 µM
Incubation Time: 72 hours
Result: Showed antiproliferative activity at a concentration of 10 μM.

Western Blot Analysis[1]

Cell Line: RL95-2 cell line
Concentration: 20 µM
Incubation Time: 24 hours
Result: Reduced the phosphorylation of ERα, while it did not alter the phosphorylation of Akt. Reduced the ratio of p-ERα/ERα compared to the control group.
In Vivo

MPP (Low dose 20 μg/kg body weight or high dose 200 μg/kg body weight) leads to a dose-dependent attenuation of percent prepulse inhibition (PPI)[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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%.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
