Description

Pyridone 6, also known CMP 6 or JAK Inhibitor I, is a pan-Janus-activated kinase inhibitor, Pyridone 6 interferes with JAK kinase activity by interacting within the ATP-binding cleft. It inhibits JAK1, 2, and 3 with IC50 values of 15, 1, and 5 nM, respectively. Pyridone 6 suppresses osteoclast formation and bone resorption through down-regulation of receptor activator of nuclear factor-kappaB (NF-kappaB) ligand (RANKL)-induced c-Fos and nuclear factor of activated T cells (NFAT) c1 expression. Pyridone 6 induces growth inhibition of multiple myeloma cells.

How to use

In Vitro:

MERcK-5 is tested as an inhibitor of 21 other protein kinases; MERcK-5 inhibits these kinases with IC50s ranging from 130 nM to >10 μM. MERcK-5 inhibits IL2 driven proliferation of CTLL cells with IC50=0.1 μM and IL4 driven proliferation with IC50=0.052 μM. MERcK-5 (P6) is shown to inhibit kinase by interacting within the ATP-binding cleft of each JAK. The IC50 of MERcK-5 is 3 nM for all of these cytokines; this is comparable to the reported IC50s of MERcK-5 for JAK2, Tyk2, and JAK3. MERcK-5 strongly inhibits Th2 and modestly inhibits Th1, whereas it enhances Th17 development when present within a certain range of concentrations. MERcK-5 reduces IFN-γ and IL-13, whereas it enhances IL-17 and IL-22 expression. MERcK-5 also inhibits both Th1 and Th2 development, whereas it promotes Th17 differentiation from naive T cells when present within a certain range of concentrations.

In Vivo:

MERcK-5 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.
