| 产品描述: | 选择性靶向Stat5的SH2结构域的细胞可渗透性化合物(IC50 = 47 µM,针对STAT5b SH2结构域EPO肽结合;a cell-permeable compound that selectively targets the SH2 domain of Stat5 (IC50 = 47 μM against STAT5b SH2 domain EPO peptide binding;Stat5抑制剂是一种细胞可渗透的非peticic烟酰via,可通过与SH2结构域结合来抑制STAT5。研究表明,Stat5抑制剂抑制STAT1和STAT3的SH2结构域的程度比STAT5抑制作用小。另外,K562核提取物中的STAT5 / STAT5 DNA结合也被Stat5抑制剂抑制。STAT5在各种过程中具有生物学功能,例如造血干细胞的体内平衡,血细胞的发育,生长激素的作用以及乳腺上皮的分化。Stat5抑制剂被证明可阻断K562核提取物中的STAT5 / STAT5 DNA结合活性,并抑制Daudi;Stat5 Inhibitor is a cell permeable nonpetidic nicotinoyl hydrazone which suppresses STAT5 via binding to the SH2 domain. Studies indicate that Stat5 Inhibitor suppresses the SH2 domain of STAT1 and STAT3 to a lesser extent than STAT5 inhibition. In addition, STAT5/STAT5 DNA binding in K562 nuclear extracts are inhibited by Stat5 Inhibitor. STAT5 functions biologically in various processes such as homeostasis of hematopoietic stem cells, development of blood cells, growth hormone effects, and differentiation of mammary epithelium. Stat5 Inhibitor is shown to block STAT5/STAT5 DNA binding activity in K562 nuclear extract and inhibit IFN-α-stimulated STAT5, but not STAT1 or STAT3, tyrosine phosphorylation in Daudi cells. |
