MA242 free base 

Cat. No.: HY-112816A
Handling Instructions

MA242 free base is a specific dual inhibitor of MDM2 and NFAT1. MA242 free base directly binds both MDM2 and NFAT1 with high affinity, induces their protein degradation, and inhibits NFAT1-mediated transcription of MDM2. MA242 free base induces apoptosis in pancreatic cancer cell lines regardless of p53 status.

Description

MA242 free base is a specific dual inhibitor of MDM2 and NFAT1. MA242 free base directly binds both MDM2 and NFAT1 with high affinity, induces their protein degradation, and inhibits NFAT1-mediated transcription of MDM2. MA242 free base induces apoptosis in pancreatic cancer cell lines regardless of p53 status[1].

IC50 & Target

MDM2, NFAT1[1]

In Vitro

MA242 (0.05-5 μM; 72 hours) free base significantly inhibits pancreatic cancer cell growth, with IC50s ranging from 0.1 to 0.4 μM, regardless of the p53 status of the cells. However, MA242 free base shows minimal effects on the growth of normal HPDE cells (IC50=5.81 μM), indicating that MA242 has selective effects against cancer cells[1].
MA242 (0.1-0.5 μM; 24 hours) free base significantly decreases the MDM2 and NFAT1 protein levels at a low concentration in all three cell lines[1].
MA242 free base decreases cell proliferation and induces apoptosis in pancreatic cancer cell lines regardless of p53 status[1].
MA242 free base alone or in combination with Gemcitabine inhibits pancreatic tumor growth and metastasis without any host toxicity[1].
MA242 free base exerts cytotoxicity against hepatocellular carcinoma (HCC) cells by inhibiting the NFAT1-MDM2 pathway in vitro, independent of p53. MA242 showed selective cytotoxicity against HCC cells, with IC50 values ranging from 0.1-0.31 μM[2].

Cell Viability Assay[1]

Cell Line: The human pancreatic cancer HPAC, Panc-1, AsPC-1, Mia-Paca-2 and BxPC-3 cell lines; The human pancreatic ductal epithelium (HPDE) cell line
Concentration: 0.05, 0.5, and 5 μM
Incubation Time: 72 hours
Result: The IC50s are 0.14, 0.14, 0.15, 0.25, 0.40, and 5.81 μM for Panc-1, Mia-Paca-2, AsPC-1, BxPC-3, HPAC, and HPDE cells, respectively.

Western Blot Analysis[1]

Cell Line: The human pancreatic cancer HPAC, Panc-1, and AsPC-1 cell lines
Concentration: 0, 0.1, 0.2, and 0.5 μM
Incubation Time: 24 hours
Result: Decreased the expression of MDM2 and NFAT1.
In Vivo

MA242 (IP; 2.5, 5, 10 mg/kg) free base suppresses orthotopic pancreatic tumor growth in vivo, independent of p53[1].
There were no significant differences in the average body weights between the vehicle- and MA242 free base-treated mice in either of the models, did not have significant host toxicity at these effective doses[1].

Animal Model: Female 4-6-week-old athymic nude mice (nu/nu, 4-6 weeks) bearing AsPC-1-Luc or Panc-1-Luc tumor[1]
Dosage: 2.5 or 5 mg/kg for Panc-1 tumor-bearing mice; 10 mg/kg for AsPC-1 tumor-bearing mice
Administration: IP; 2.5 or 5 mg/kg/d, 5 d/wk for five weeks for Panc-1 tumor-bearing mice;
IP; 10 mg/kg/d, 5 d/wk for three weeks for AsPC-1 tumor-bearing mice
Result: Resulted in 56.1% and 82.5% inhibition of tumor growth in nude mice bearing Panc-1 orthotopic tumors, respectively.
Significantly suppressed the growth of AsPC-1 orthotopic tumors by 89.5% (P < 0.01) compared with the tumors in control animals.
Led to almost complete tumor regression in MD242-treated mice in both models.

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.
