XL-388 is a drug which acts as a potent and selective inhibitor of both subtypes of the mechanistic target of rapamycin (mTOR), mTORC1 and mTORC2.[1] It is being researched for the treatment of various forms of cancer,[2][3][4] and has also been used to demonstrate a potential application for mTOR inhibitors in the treatment of neuropathic pain.[5][6]
