Resatorvid (TAK-242) is a cyclohexane derivative that was invented by scientists at Takeda in a drug discovery campaign to identify inhibitors of the receptor TLR4.^[1] It binds directly to cysteine residue 747^[1] intracellularly, preventing TLR4 binding with TIRAP and thus preventing downstream signal transduction.^[2]

A randomized, double-blinded Phase III trial of resatorvid in sepsis was halted early due to lack of efficacy, and the compound has become a widely used tool compound in biological research.^[1]

It has antiinflammatory and neuroprotective effects in preclinical models.^[3] It has been explored in preclinical studies of several forms of cancer, including multiple myeloma, breast cancer, and ovarian cancer,^[4] and has been suggested for study in skin cancers.^[5]

Efforts have been made to improve resatorvid by making prodrugs and deuterated derivatives.^[3]
