tcsc0408 Resatorvid

Resatorvid (TAK-242) is a potent TLR4 signaling inhibitor which selectively inhibits the TLR4-mediated production of cytokines and nitric oxide.

IC50 & Target: TLR4^[1]

In Vitro: In RAW264.7 cells and mouse peritoneal macrophages, Resatorvid (TAK-242) suppresses lipopolysaccharide (LPS)-induced production of NO, tumor necrosis factor-α (TNF-α), and interleukin (IL)-6, with IC₅₀ of 1.1 to 11 nM. Resatorvid (TAK-242) also suppresses the production of these cytokines from LPS-stimulated human peripheral blood mononuclear cells (PBMCs) at IC₅₀ values from 11 to 33 nM^[1].

In Vivo: Resatorvid (TAK-242) apparently reduces the serum anti-dsDNA levels in both genotype mice. Alternatively, IFN-γ, TNF-α, and IL-1β production is markedly inhibited by Resatorvid (TAK-242), but their concentrations are still greatly higher than those in NS-treated counterparts^[2]. Resatorvid (TAK-242) pre-stress administration prevents the accumulation of potentially deleterious inflammatory and oxidative/nitrosative mediators in the brain frontal cortex of rats. Resatorvid (TAK-242) i.v. administration at the beginning of the stress session completely blocks TLR-4 mRNA and protein upregulation after stress exposure^[3].
