| 产品描述: | STAT抑制剂;STAT Inhibitors;产品介绍AS1517499是一种新型有效的STAT6抑制剂,IC50为21 nM。;InformationAS1517499 AS1517499 is a novel and potent STAT6 inhibitor with an IC50 value of 21 nM.TargetsSTAT6 (Cell-free assay) 21 nMIn vitroAS1517499 inhibit IL-4-induced Th2 differentiation of mouse spleen T cells, but has no influence on Th1 differentiation induced by IL-12. AS1517499 is able to prevent the IL-4-activated STAT6-mediated increase of the clonogenic potential of primary PCa cells. At a dose of 300\u2009nM, AS1517499 decreases the clonogenic potential of primary basal PCa cells.In vivoIn vivo treatment with AS1517499 ameliorates the antigen-induced bronchial smooth muscle (BSM) hyperresponsiveness by inhibiting the RhoA up-regulation in BSMs and, at least in part, by reducing the IL-13 production in the airways in mice. AS1517499 reduces preventive effects of apoptotic cell instillation on bleomycin-induced lung fibrosis by suppressing PPARγ.Cell Research(from reference)Cell lines:Normal human BSM cells Concentrations:100 nM Incubation Time:30 min |
| 体内研究: |
在用卵清蛋白抗原主动致敏和反复攻击的 BALB/c 小鼠中,在最后一次抗原攻击后观察到支气管肺泡灌洗液中 IL-13 水平升高和支气管组织中 STAT6 磷酸化。这些小鼠具有增强的 BSM 对乙酰胆碱的收缩力以及支气管组织中 RhoA 的上调。在每次卵清蛋白暴露前 1 小时腹膜内注射 AS1517499 (10 mg/kg) 几乎完全抑制抗原诱导的 RhoA 和 BSM 高反应性上调。 |
