XRP44X

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]. 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]. In Vivo: XRP44X may have therapeutic potential for refractory asthma^[1].
XRP44X, an inhibitor of Ras/Erk activation of the transcription factor Elk3, inhibits tumor growth and metastasis in mice. XRP44X inhibits tumor growth and metastasis in nude mice. XRP44X decreases the growth of tumours and the formation of metastases in nude mice^[2].
