目录号: HY-100754A
产品使用指南 技术支持

Ritlecitinib (PF-06651600) malonate 是一种高选择性、口服有效的、不可逆共价 JAK3 抑制剂 (IC50=33 nM),对 JAK1、JAK2 和 TYK2 几乎无活性 (IC50 >10 μM)。Ritlecitinib malonate 快速使 JAK3 激酶失活并阻断共同 γ 链细胞因子 (如 IL-2IL-15) 介导的信号传导和下游 STAT 磷酸化。Ritlecitinib malonate 可抑制 Th1/Th17 细胞分化和功能,并有效抑制斑秃、佐剂性关节炎 (AIA) 和实验性自身免疫性脑脊髓炎 (EAE) 等临床前动物模型。

生物活性

Ritlecitinib (PF-06651600) malonate is a highly selective, orally active, irreversible covalent JAK3 inhibitor (IC50=33 nM) without inhibitory activity towards JAK1, JAK2, and TYK2 (IC50 >10 μ M). Ritlecitinib malonate rapidly inactivates the JAK3 kinase, and blocks signaling and downstream STAT phosphorylation mediated by common gamma chain cytokines such as IL-2 and IL-15. Ritlecitinib malonate can inhibit Th1/Th17 cell differentiation and function, and effectively suppress preclinical animal models such as alopecia areata, adjuvant-induced arthritis (AIA), and experimental autoimmune encephalomyelitis (EAE)[1][2][3].

体外研究
(In Vitro)

Ritlecitinib malonate 抑制外周血单个核细胞 (PBMC) 和肝素处理的人全血 (HWB) 中 IL-15 的 IC50 分别为 51 nM 和 197 nM[1]
Ritlecitinib malonate 在 IL-2、IL-4、IL-7 和 IL-15 诱导 STAT 蛋白磷酸化抑制实验中,分别以 244 nM、340 nM、407 nM、266 nM、355 nM 浓度 (IC50) 抑制 IL-2 (STAT5)、 IL-4 (STAT6)、 IL-7 (STAT5)、 IL-15 (STAT5)、 IL-21 (STAT3) 介导的磷酸化[2]
Ritlecitinib malonate (30 nM、167 nM;5 天、6 天) 在 Th1 和 Th17 细胞分化抑制实验中,分别于 Th1 条件下 5 天和 Th17 条件下 6 天抑制细胞分化[2]

Western Blot Analysis[1]

Cell Line: Mouse splenocytes, human whole blood lymphocytes (HWB)
Concentration: 33.1 nM, 244 nM, 340 nM, 407 nM, 266 nM, 355 nM
Incubation Time: 1 hour (pre-treatment with Ritlecitinib malonate) + 15-20 minutes (cytokine stimulation)
Result: In mouse splenocytes, 33.1 nM inhibited JAK3 kinase activity, while 244 nM, 340 nM, 407 nM, and 266 nM inhibited STAT5 phosphorylation induced by IL-2, IL-4, IL-7, and IL-15 respectively. In human whole blood lymphocytes, 355 nM inhibited IL-21-induced STAT3 phosphorylation.

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.
