Resatorvid is a novel selective Toll-like receptor 4 signal transduction inhibitor. Resatorvid inhibits various kinds of inflammatory mediators such as nitric oxide (NO), tumor necrosis factor (TNF)-α
, interleukin (IL)-1, IL-6, IL-10, macrophage inhibitory protein (MIP)-2 and prostaglandin E2 from lipopolysaccharide (LPS)-stimulated macrophages. | [General Description]
A cell-permeable cyclohexenecarboxylate that disrupts TLR4, but not TLR1-3 or TLR5-10, interaction with adaptor molecules TIRAP and TRAM via direct binding to TLR4 intracellular Cys747 residue.Shown to effectively inhibit TLR4-mediated cellular events (IC50 = 1.8, 1.3, and 1.9 nM, respectively, against LPS-induced NO, IL-6, and TNF-α production in murine RAW264.7 macrophages) in vitro and completely prevent LPS- (7 mg/kg, i.p.) induced death in mice (3 mg/kg; i.v.) in vivo. Also available as a 25 mM solution in DMSO (Cat. No. 508336). | [Biological Activity]
toll, a member of the toll-like receptor (tlr) family, was identified as a gene product essential for the development of embryonic dorsoventral polarity in drosophila melanogaster. moreover, it has been also found to play a critical role in the antifungal response of flies. tak-242 (resatorvid), a cyclohexene derivative, is recongnizred as a novel small-molecule compound selectively inhibiting tlr4 signaling. | [Biochem/physiol Actions]
Cell permeable: yes | [in vitro]
a previous in-vitro study showed that tak-242 could inhibit the production of lipopolysaccharide-induced inflammatory mediators by binding to the intracellular domain of tlr4 using coimmunoprecipitation approach. among 10 different human tlrs, tak-242 selectively bound to tlr4. these findings suggested that tak-242 could selectively bind to tlr4 and disrupted the interaction of tlr4 with adaptor molecules, thereby inhibiting tlr4 signal transduction and its downstream signaling [2]. | [in vivo]
preclinical animal study demonostrated that the acute restraint stress exposure upregulateed tlr-4 expression both at the mrna and protein level in rat. tak-242 pre-stress administration prevented the accumulation of potentially deleterious inflammatory and oxidative/nitrosative mediators in the brain frontal cortex of rats. these finding s indicated that the use of tak-242 or other tlr-4 signalling pathway inhibitory compounds could be considered as a potential therapeutic adjuvant strategy to constrain the inflammatory process taking place after stress exposure and in stress-related neuropsychiatric diseases [3]. | [IC 50]
with ic50 of 1.1 to 11 nm, tak-242 inhibited lps-induced no production, tumor necrosis factor-alpha and interleukin (il)-6 in raw264.7 cells and mouse peritoneal macrophages [1]. | [storage]
