JTE-607

JTE-607 is a multiple cytokine inhibitor. It inhibits cytokine production specifically in human peripheral blood mononuclear cells without causing immunosuppression. It inhibits tumor necrosis factor-α (TNF-α), interleukins IL-1β, IL-6, IL-8 and IL-10 from LPS-stimulated human PBMCs with IC₅₀ values of 11 nM, 5.9 nM, 8.8 nM, 7.3 nM and 9.1 nM, respectively. It (0.4-0.8 μM) also inhibits the growth of acute myelogenous leukemia cell lines by inducing apoptosis and cell-cycle arrest.
