RapaLink-1, the third-generation bivalent mTOR inhibitor, combines Rapamycin (HY-10219) with MLN0128 (HY-13328, a second-generation mTOR kinase inhibitor) by an inert chemical linker. RapaLink-1 shows better efficacy than Rapamycin or mTOR kinase inhibitors (TORKi), potently blocking cancer-derived, activating mutants of mTOR. RapaLink-1 can cross the blood-brain barrier. RapaLink-1 binding to FKBP12 results in targeted and durable inhibition of mTORC1. RapaLink-1 plays an antithrombotic role in antiphospholipid syndrome by improving autophagy. Anticancer activity[1][2].
