半岛bd体育手机客户端 描述

Pyridone 6 is a pan-JAK inhibitor, which potently inhibits the JAK kinase family, with IC50s of 1 nM for JAK2 and TYK2, 5 nM for JAK3, and 15 nM for JAK1, while displaying significantly weaker affinities (130 nM to >10 mM) for other protein tyrosine kinases.

JAK1,15nM

JAK2,1nM

JAK3,5nM

Tyk2,1nM

体外研究

Pyridone 6 is tested as an inhibitor of 21 other protein kinases; Pyridone 6 inhibits these kinases with IC50s ranging from 130 nM to >10 μM. Pyridone 6 inhibits IL2 driven proliferation of CTLL cells with IC50=0.1 μM and IL4 driven proliferation with IC50=0.052 μM[1]. Pyridone 6 (P6) is shown to inhibit kinase by interacting within the ATP-binding cleft of each JAK. The IC50 of Pyridone 6 is 3 nM for all of these cytokines; this is comparable to the reported IC50s of Pyridone 6 for JAK2, Tyk2, and JAK3. Pyridone 6 strongly inhibits Th2 and modestly inhibits Th1, whereas it enhances Th17 development when present within a certain range of concentrations. Pyridone 6 reduces IFN-γ and IL-13, whereas it enhances IL-17 and IL-22 expression. Pyridone 6 also inhibits both Th1 and Th2 development, whereas it promotes Th17 differentiation from naive T cells when present within a certain range of concentrations[2].

体内研究

Pyridone 6 (P6) delays the onset and reduced the magnitude of skin disease in an AD-like skin-disease model of NC/Nga mice. P6-nano strongly ameliorates atopic dermatitis (AD) in NC/Nga mice, exerting an effect comparable to that of betamethasone ointment, a commonly used drug, which also tested as a positive control. In contrast, empty polylactic acid with glycolic acid (PLGA) nanoparticles (C-nano) seemed to have no effect[2].

细胞实验

Naive CD4+ T cells are treated with various concentrations of Pyridone 6 (10 and 30 nM) in RPMI 1640 medium 1 h before the appropriate cytokines are added to create each Th-differentiating condition. Immunoblotting is performed using antiphospho-STAT protein Abs or anti-total STAT protein Abs[2].MCE has not independently confirmed the accuracy of these methods. They are for reference only.

动物实验

Mice[2] NC/Nga mice are used at the age of 10-15 wk. To assess the effect of Pyridone 6 treatment on AD symptoms, nanoparticles containing Pyridone 6 (2 mg/body) or empty nanoparticles as a negative control (C-nano) are dissolved in 0.1 mL saline and administered s.c. 1 d after Dfb ointment application; this treatment is repeated twice a week. To assess the effects of recombinant murine IL-17 and IL-22, these cytokines (50 μg/kg) or 100 μL PBS is administered for the same duration as the nanoparticles. Twenty milligrams of 0.064% betamethasone ointment are applied to the dorsal lesion of mice once a week[2].MCE has not independently confirmed the accuracy of these methods. They are for reference only.
