Description

XRP44X inhibits Ras-induced transcription activation with the IC50 of 10 nM. XRP44X inhibits activation of the Ras-Erk-1/2 pathway by FGF-2[1]. XRP44X is an inhibitor of Ras/Erk activation of Elk3 that also affects microtubules[2].

IC50 & Target[1]

Ras

10 nM (IC50)

In Vitro

XRP44X is an indirect inhibitor of Net phosphorylation that acts upstream from Erk-1/2 activation. XRP44X inhibits luciferase activity with the IC50 of~10 nM[1].
XRP44X (10 nM) inhibits cell growth of HUVEC, NIH3T3, HCT-116, and NIH3T3–Ki-Ras cells[1].
XRP44X (100 nM) inhibits phosphorylation of Mek-1/2 and Raf-1[1].

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.
