沸点：587.7±50.0 °C(Predicted)
密度：1.151±0.06 g/cm3(Predicted)
包装规格：2mg 5mg in glass bottle
产品简介：一种有效的、可口服的TLR7和TLR9拮抗剂，可用于有害炎症反应的研究。E6446 还是强效的 SCD1 抑制剂 (KD: 4.61 μM)，通过SCD1-ATF3信号传导显着抑制脂肪形成分化和肝脂肪生成。E6446还改善高脂饮食(HFD)喂养小鼠的肝脏病变，可用于非酒精性脂肪肝病(NAFLD)的研究。
溶解性：Ethanol:90.0(Max Conc. mg/mL);200.18(Max Conc. mM)
储备液保存：-80°C, 6 months; -20°C, 1 month。
体内实验：1、请依序添加每种溶剂： 10% DMSO→40% PEG300→5% Tween-80→45% Saline Solubility: ≥ 0.83 mg/mL (1.85 mM); 澄清溶液 此方案可获得 ≥ 0.83 mg/mL（饱和度未知）的澄清溶液。 以 1 mL 工作液为例，取 100 μL 8.3 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；再向上述体系中加入50 μL Tween-80，混合均匀；然后再继续加入 450 μL 生理盐水 定容至 1 mL。 注：建议您现用现配，当天使用。 ＜1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得，实际溶液度可能与公布值有所偏差，属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液；一旦配成溶液，请分装保存，避免反复冻融造成的产品失效。
靶点：TLR7;TLR9
体外研究：E6446 is a potent and orally acitve TLR7 and TLR9 inhibitor. E6446 potently suppresses DNA stimulation of HEK:TLR9 cells, with an IC50 value of 10 nM, but is significantly less effective at suppressing LPS endotoxin stimulation of HEK:TLR4 cells or R848 stimulation of HEK:TLR7 cells.E6446 potently inhibits IL-6 production induced by CpG2216 but is ineffective against induction by the TLR3 ligand poly inosine-cytosine. The ability of E6446 to inhibit TLR7 is ligand dependent, E6446 is a potent inhibitor of IL-6 induction by RNA but a relatively poor inhibitor of IL-6 induction by the small molecule imidazoquinoline ligand R-848. E6446 suppress TLR9-DNA interaction in vitro, with an IC50 in the 1 to 10 µM range. E6446 (0.01-0.03 μM) specifically inhibits TLR9 activation with CpG ODN 2006, and blocks TLR7/8 activated by the imidazoquinoline compound R848 at 2-8 μM. E6446 reduces 50% of TLR4 activation at 30 μM, and shows IC50s of 0.01 μM and 0.23 μM in HEK-TLR9 cells stimulated with oligo 2006 and in human PBMCs stimulated with oligo 2216, respectively.
体内研究：E6446 (20 mg/kg, p.o.) almost cmlpletely inhibits CpG1668-induced IL-6 production, and dose-dependently suppresses the development of ANA (anti-nuclear antibodies) in mice at 20 and 60 mg/kg. E6446 (20, 60 mg/kg, p.o.) dose-dependently inhibits TLR9 signaling in mice. E6446(60, 120 mg/kg, p.o.) prevents hyperresponsiveness of TLRs and LPS-induced septic shock in rodent malaria, diminishes TLR responsiveness during acute malaria, suppresses activation of both TLR7 and TLR9.
保存条件：-20°C
