生物活性:
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.
体内研究:
RapaLink-1 (i.p.; every 5 days for 25 days, then once a week for 11 week) shows potent anti-tumor efficacy.Animal Model:BALB/ Cnu/nu mice bearing U87MG intracranial xenografts
Dosage:1.5 mg/kg
Administration:I.p.; every 5 days for 25 days, then once a week for 11 week
Result:Led to initial regression and subsequent stabilization of tumor size.
体外研究:
RapaLink-1 (0-200 nM; 3 days) shows U87MG cells growth inhibition.RapaLink-1 (0-12.5 nM; 48 hours) arrests U87MG cells at G0/G1.RapaLink-1 selectively inhibits p-RPS6S235/236 and p-4EBP1T37/46 at doses as low as 1.56 nM. Rapalink-1 (100 nM; 24 to 96 hours) suppressed renal cell carcinoma (RCC) cell proliferation by inducing apoptosis and cell cycle arrest.?RapaLink-1 exploits the unique juxtaposition of two drug-binding pockets to create a bivalent interaction. RapaLink-1 overcomes resistance to existing first- and second-generation inhibitors.
