SH-4-54
CAS No. : 1456632-40-8
MCE 国际站:SH-4-54
产品活性:SH-4-54是 STAT 的抑制剂,与 STAT3 和 STAT5 结合的 KDs 值分别为300,464 nM。
研究领域:JAK/STAT Signaling | Stem Cell/Wnt
作用靶点:STAT
In Vitro: SH-4-54 potently kills glioblastoma brain cancer stem cells (BTSCs) and effectively suppresses STAT3 phosphorylation and its downstream transcriptional targets at low nM concentrations.SH-4-54 shows unprecedented cytotoxicity in human BTSCs, displays no toxicity in human fetal astrocytes, potently suppresses pSTAT3 with nanomolar IC50s, inhibiting STAT3's downstream targets, and shows no discernible off-target effects at therapeutic doses.
In Vivo: SH-4-54 exhibits blood-brain barrier permeability potently controls glioma tumor growth, and inhibits pSTAT3 in vivo. SH-4-54 demonstrates the power of STAT3 inhibitors for the treatment of BTSCs and validates the therapeutic efficacy of a STAT3 inhibitor for GBM clinical application.SH-4-54 decreases pSTAT3 expression in tumor cells of treated mice. SH-4-54 appears to decrease proliferation and increase apoptosis of treated tumors.
