STAT5 Inhibitor is a cell-permeable inhibitor of STAT5 with IC50 value of 47 μM against STAT5β SH2 domain EPO peptide binding activity [1].
Signal Transducers and Activators of Transcriptions (STATs) are a family of transcription factors that are primarily activated by membrane receptor-associated Janus kinases (JAK) in response to a large number of extracellular signaling molecules including interferons, cytokines, and growth factors, and mediate many aspects of cellular immunity, proliferation, apoptosis and differentiation [2][3]. STAT5 consists of two isoforms STAT5α and STAT5β and is overactive in several kinds of cancers [1].
STAT5 Inhibitor is a cell-permeable STAT5 inhibitor. STAT5 Inhibitor inhibited STAT5β SH2 domain EPO peptide binding activity with IC50 value of 47 μM and exhibited less potency inhibiting the SH2 domain of STAT1, STAT3, and LCK by 36%, 26% and 7% at 500 μM, respectively [1]. In lysates from K562 cells, STAT5 Inhibitor reduced the concentration of STAT5/STAT5/DNA complex in a dose-dependent way [1].

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
