W146 (trifluoroacetate salt) is a selective antagonist of Sphingosine 1-phosphate receptors 1 (S1PR1) with an EC50 value of 398nM[1].W146 (trifluoroacetate salt) is widely used to investigate S1P/S1PR1-mediated biological processes.
In vitro, W146 (trifluoroacetate salt) (10μM) was employed for 30min in HEK293 and CHO-K1 cells stably expressing S1P receptor. W146 (trifluoroacetate salt) completely abolished a water-soluble highly-selective S1PR1 agonist CYM-5442- or S1P-induced S1PR1 internalization, phosphorylation and ubiquitination, and p42/p44 MAPK activation[2]. W146 (trifluoroacetate salt) (1µM) pretreated microglia for 30min before siponimod treatment and then the cells were stimulated with 1µg/mL LPS alone (for 24h) or 1µg/mL LPS (for 3.5h) plus 10µM inflammasome activator nigericin (for the final 30min). Pretreatment with W146 (trifluoroacetate salt) and siponimod significantly suppressed the production of interleukin-1β in activated microglia stimulated with lipopolysaccharide plus nigericin[3].W146 (trifluoroacetate salt) (10μM) was applied to cultured rat fat-pad endothelial cells (RFPECs) and human coronary artery endothelial cells for 10min and then the cells were exposed to S1P or plasma protein-containing media for 2 hours. W146 (trifluoroacetate salt) abolished the protective role of S1P and plasma proteins on the glycocalyx[4].
In vivo, W146 (trifluoroacetate salt) (10mg/kg) was administered intraperitoneally into non fasted Swiss mice and induced a significant but transient blood lymphopenia in mice and a parallel increase in CD4+ and CD8+ lymphocytes in lymph nodes[5].W146 (trifluoroacetate salt) (0.1mg/kg) was administrated into C57BL/6 mice via intraperitoneal injection daily for 3 days before animals subjected to 20 minutes of renal ischemia followed by 24 hours of reperfusion. W146 (trifluoroacetate salt)-treated mice exhibited significantly exacerbated renal and hepatic injury[6]. W146 (trifluoroacetate salt) (5mg/kg) injected intraperitoneally 1h before AMD3100 administration significantly enhanced the mobilization of Kit+/Sca-1+/Lin− (KSL) hematopoietic stem and progenitor cells in C57BL/6 mice by approximately 8-fold[7].

体外实验中，W146 (trifluoroacetate salt)（10μM）处理稳定表达S1P受体的HEK293和CHO-K1细胞30分钟，W146 (trifluoroacetate salt)完全阻断了水溶性、高选择性S1PR1激动剂CYM-5442或S1P诱导的S1PR1内化、磷酸化、泛素化以及p42/p44 MAPK的激活[2]。在siponimod处理前，W146 (trifluoroacetate salt)（1μM）预处理小胶质细胞30分钟，随后细胞单独用1μg/mL LPS刺激24小时，或1μg/mL LPS刺激3.5小时并在最后30分钟加入10μM炎症小体激活剂nigericin。W146 (trifluoroacetate salt)和siponimod的预处理显著抑制了经LPS加nigericin激活的小胶质细胞中白细胞介素-1β的产生[3]。W146 (trifluoroacetate salt)（10μM）处理培养的大鼠脂肪垫内皮细胞（RFPECs）和人冠状动脉内皮细胞10分钟，随后细胞暴露于S1P或含血浆蛋白的培养基中2小时，W146 (trifluoroacetate salt)消除了S1P和血浆蛋白对糖萼的保护作用[4]。
在体内实验中，W146 (trifluoroacetate salt)（10mg/kg）经腹腔注射给予非禁食的Swiss小鼠，诱导了显著但短暂的血液淋巴细胞减少，并伴随淋巴结中CD4+和CD8+淋巴细胞的平行增加[5]。W146 (trifluoroacetate salt)（0.1mg/kg）经腹腔注射给予C57BL/6小鼠，每日一次，连续3天，随后进行20分钟肾脏缺血及24小时再灌注处理。W146 (trifluoroacetate salt)处理的小鼠表现出明显加重的肾和肝损伤[6]。W146 (trifluoroacetate salt)（5mg/kg）在AMD3100给药前1小时经腹腔注射，显著增强了C57BL/6小鼠中Kit+/Sca-1+/Lin−（KSL）造血干细胞和祖细胞的动员，增幅约达8倍[7]。
