Biological Activity

Description NSC228155 is an activator of EGFR. It binds to the sEGFR dimerization domain II and modulates EGFR tyrosine phosphorylation.
Targets
EGFR [2]
()
KIX-KID interaction [3]
0.36 μM
In vitro

NSC 228155 promotes transactivation of several RTKs, including ErbB2 and ErbB3, Insulin R and IGF-1 R receptors in the cells. It stimulates dimerization of sEGFR domain II[1]. NSC 228155 can rapidly move across cell membranes and disperse within both cytoplasmic and nuclear compartments. It rapidly generates hydrogen peroxide within cells[2]. NSC 228155 is also a potent inhibitor of KIX-KID interaction(IC50 = 0.36 μM), but it is not particularly selective against CREB-mediated gene transcription in HEK 293T cells[3].

Protocol (from reference)

Cell Research:[1]
  • Cell lines: MDA MB468 cells
  • Concentrations: 100 μM
  • Incubation Time: 15 min
  • Method: MDA MB468 cells serum-starved overnight are pre-incubated (or not) with 10 μM AG1478 or 2 μM PD 153035 for 90 min and then, where indicated, incubated with 100 μM NSC 228155 or CN 009543V or 150 ng/ml EGF or vehicle (0.2% DMSO) for 15 min. Proteins are blotted to nitrocellulose membrane and analyzed with biotinylated anti-pTyr P100, anti-pEGFR Y1068 and anti-EGFR (epitope in cytoplasmic region) antibodies.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
