WYE-687 is an ATP-competitive and selective inhibitor of mammalian target of rapamycin (mTOR). Studies have shown the combination of Ras-Raf-MEK1/2 inhibitors with WYE-687 may overcome resistance to m TorKIs thus may be an effective additive therapy for treatment of patient with renal cell carcinoma or colorectal cancer.

wye-687 is an atp-competitive inhibitor of mtor with ic50 value of 7nm [1].wye-687 is a small-molecule pyrazolopyrimidine inhibitor of mtor1 and mtor2. in the immune-complex kinase assay using his6-akt and his6-s6k as the specific substrates of mtor1 and mtor2, wye-687 prevents mtor from phosphorylating the substrates dose-dependently. besides that, wye-687 is found to highly selective against pi3kα (>100-fold) and pi3kγ (>500-fold) as well as 24 other protein kinases. it is found that wye-687 can suppress cell growth via causing a strong g1 arrest in cell cycle in tumor cell lines including mda361 and hct116. wye-687 also affects the angiogenic factor of cancer cells. it reduces the expression of hif-1α in u87mg, mda361 and lncap cells [1].
