生物活性

BMS-986126 is a potent, selective, and orally active IRAK4 inhibitor (IC50 = 5.3 nM). BMS-986126 broadly inhibits MyD88-dependent signaling pathways. BMS-986126 demonstrates robust activity in the MRL/lpr and NZB/NZW murine models of lupus, inhibiting multiple pathogenic responses. BMS-986126 can be used for autoimmune diseases research, such as lupus erythematosus (SLE)[1].

BMS-986126 对人外周血单核细胞 (PBMC) 中多种 MyD88 依赖性 TLR (TLR2/5/7/9) 表现出相似的纳摩尔级效力 (IC50:135-456 nM),并能有效抑制 NF-κB 调节的 IL-6 和 I 型干扰素 (IFN-α) 反应,甚至抑制 IL-1β 和 IL-18 诱导的细胞因子[1]
BMS-986126 对 MyD88 非依赖性激动剂 TLR3 和 TNF-α 诱导的细胞因子产生无显著影响[1]
BMS-986126 (0-2 μM,30 分钟) 剂量依赖性地抑制人 PBMC 中 TLR2TLR4 下游的 IKKα/β 和 ERK 以及 TLR7 下游的 ERK 的磷酸化[1]
BMS-986126 在抑制健康供体和系统性红斑狼疮患者 PBMC 中 TLR7/9 诱导的干扰素反应基因表达 (例如 IFIT1) 方面表现出同等效力[1]
BMS-986126 (5 μM,30 分钟) 可广泛逆转人 PBMC 中 TLR7 激活诱导的基因表达谱,其中相当一部分被抑制的基因是经典的干扰素刺激基因[1]
BMS-986126 (16-80 nM,30 分钟) 与 Prednisolone (HY-17463) 联用可协同抑制人 PBMC 中 TLR9 诱导和流感病毒诱导的 IFIT1 表达,其抑制作用显著强于单药[1]

BMS-986126 (0.1-3 mg/kg,口服,单次给药,在 LTA/CpG-ODN/Gardiquimod 前 30 分钟给药) 可抑制小鼠体内多种MyD88依赖性 TLR (TLR2/7/9) 下游的细胞因子生成[1]
BMS-986126 (0.3-10 mg/kg,口服,每日一次,持续 6 天或 8 周) 可显著抑制自发性 (MRL/lpr 和 NZB/NZW) 小鼠狼疮模型中的疾病活动[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
