C-178，STING 的共价抑制剂，与 Cys91 有效结合并选择性地抑制小鼠中不同的激活剂引起的 STING 反应。C-178 选择性地降低 STING- 而非 RIG-I- 或 TBK1- 介导的 IFN-β 报告基因活性。C-178 阻断棕榈酰化 (PMA) 诱导的 STING 类聚；抑制 CMA 诱导的 TBK1 (STING 下游蛋白激酶) 磷酸化。

| 产品描述 | C-178, a covalent inhibitor of STING, binds to Cys91, potently and selectively suppresses the STING responses elicited by distinct bona fide activators in mouse but not human. C-178 significantly reduces STING-, but not RIG-I- or TBK1-, mediated IFN-β reporter activity. C-178 blocks palmitoylation (PMA)-induced clustering of STING; inhibits the CMA-induced phosphorylation of TBK1 (downstream protein kinase of STING)[1]. [1]. Haag SM, et al.
