Resatorvid (TAK-242) is a drug which acts as a selective antagonist of the receptor TLR4.[1] It has antiinflammatory[2] and neuroprotective effects following brain injury,[3] and also shows activity against some forms of skin cancer and some other cancers, and may show potential as an add-on treatment alongside conventional chemotherapy drugs.[4][5][6]
