GtoPdb Ligand ID: 9036

Synonyms: TAK-242 | TAK242
Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Resatorvid (TAK242) was first identified as an inhibitor of inflammatory mediator production in LPS treated mouse macrophages [2]. Subsequent work found that this action was attributable to the compound's activity as a Toll-like receptor 4 (TLR4) antagonist [1].

Bioactivity Comments
In vitro, resatorvid inhibits cytokine production in human PBMCs without antagonizing the binding of LPS to the CD14/TLR4/MD-2 complex [1]. Resatorvid inhibits cytokine production from mouse RAW264.7 cells stimulated with various TLR4 agonists, but not TRL2, -3 or -9 agonists, confirming it as a selective TLR4 antagonist [1]. The Ii et al. paper [1] does not provide binding assay-derived data quantifying TLR4-resatorvid antagonism, all confirmatory work involved measuring inhibition of agonist-induced cytokine expression or secretion. We have tagged TLR4 as the primary molecular target for resatorvid based on this study.
