产品详情	TEI-9648 是一种 Vitamin D₃ Lactone 类似物，是有效的，特异性的维生素 D 受体 (VDR) 拮抗剂。TEI-9648 抑制 VDR/VDRE 介导的 1α,25(OH)₂D₃ 的基因组作用。TEI-9648 也可以抑制 1α,25(OH)₂D₃ 诱导的 HL-60 细胞分化。TEI-9648 有潜力用于骨代谢的研究。
生物活性	TEI-9648, a Vitamin D 3 Lactone analogue, is a potent and specific vitamin D receptor (VDR) antagonist. TEI-9648 inhibits VDR/VDRE-mediated genomic actions of 1α,25(OH) 2 D 3 . TEI-9648 also inhibits HL-60 cell differentiation induced by of 1α,25(OH) 2 D 3 . TEI-9648 has the potential for bone metabolism research.
性状	Solid
体外研究(In Vitro)	TEI-9648 (10-1000 nM) dose-dependently blocks the reciprocal changes of CD11b and CD71 expression associated with HL-60 cell differentiation induced by 1α,25(OH)2D3. TEI-9648 has consistently weaker suppressive effect than TEI-9647. TEI-9648 can not induce cell differentiation even after treatment at 1 μM in HL-60 cell. TEI-9648 alone can not induce activation of NBT-reducing activity or α-NB esterase activity. In contrast, TEI-9648 markedly suppresses the up-regulation induced by 1α,25(OH)2D3 (0.1 nM) in HL-60 cells. has not independently confirmed the accuracy of these methods. They are for reference only.

Data Sheet

1：一般建议：溶解度为Medlife测试数据，可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解，请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异，仅做参考，具体以实验方案为准。

2：储存条件：粉末-20°C一般情况可以保存3年，溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异，请细致阅读产品信息，并辅助参考相关文献描述。
