体外研究
(In Vitro)

Ritlecitinib 是一种强效的 JAK3 选择性抑制剂,可抑制 JAK3 激酶活性,IC50 为 33.1 nM,但对 JAK1、JAK2 和 TYK2 无活性(IC50>10?000 nM)。Ritlecitinib 可抑制 IL-2、IL-4、IL-7 和 IL-15 引起的 STAT5 磷酸化,IC50 值分别为 244、340、407 和 266 nM。Ritlecitinib 还可抑制 IL-21 引起的 STAT3 磷酸化,IC50 为 355 nM。细胞分化试验中的功能评估表明,Ritlecitinib 抑制 Th1 和 Th17 分化,以 Th1 条件下 5 天后的 IFNγ 和 Th17 条件下 6 天后的 IL-17 产生来衡量,IC50 值分别为 30 nM 和 167 nM。Ritlecitinib 还抑制 Th1 和 Th17 功能,以在用 PF-06651600 处理之前已分化并处于静止状态的细胞中抑制 IFNγ 产生 (IC50=48 nM) 和 IL-17 产生 (IC50=269 nM) 来衡量[1]

体内研究
(In Vivo)

在大鼠佐剂诱发关节炎 (AIA) 模型中,Ritlecitinib 可减轻爪肿胀,未结合 EC50 为 169 nM。同样,在实验性自身免疫性脑脊髓炎 (EAE) 小鼠模型中,当以 30 或 100 mg/kg 的治疗剂量或以 20 和 60 mg/kg 的预防剂量给药时,Ritlecitinib 可显著降低疾病的严重程度。Ritlecitinib 在这两种炎症和自身免疫性疾病啮齿动物模型中的疗效表明,JAK3 选择性抑制足以对人类疾病产生疾病改善作用[1]

Cell Assay
[1]

To study the effect of PF-06651600 on Th17 cells post differentiation, skewed Th17 cells are washed, rested with medium for overnight and resuspended in medium containing the same concentrations of cytokines as during skewing but without anti-CD3 or anti-CD28 antibodies, in the presence of PF-06651600 at 10 different concentrations for 2 additional days. On Day 9, supernatant is harvested from each well and IL-17A is determined[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[1]

The effect of JAK3 inhibition by PF-06651600 is evaluated in vivo using a therapeutic dosing paradigm in a rat adjuvant-induced arthritis. When individual hind paw volume measurements indicate an increase of 0.2 mL (or greater) in a single hind paw, animals are randomly assigned to a treatment group. Daily treatment with PF-06651600 is administered via oral gavage. Treatment groups for Experiment 1 are: 80, 15, or 6 mg/kg of PF-06651600 or vehicle (2% Tween 80/0.5% methylcellulose/deionized water). Treatment groups for Experiment 2 are: 30, 10, and 3 mg/kg of PF-06651600 or vehicle (0.5% methylcellulose/de-ionized water/1 mEQ hydrochloric acid). Treatment groups for Experiment 3 are: 10, 1, 0.3 and 0.1 mg/kg of PF-06651600 or vehicle (0.5% methylcellulose/de-ionized water/1 mEQ hydrochloric acid). Treatment continues for 7 days[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.
