Background:

WYE-354 is a powerful and selective ATP-competitive kinase heterocyclic inhibitors with biochemical IC50 of 5 nM against mTOR.[1]

WYE-354 displays very specific selectivity to PI3K families (>100-fold to PI3K? and >500-fold to PI3K?), but it can’t inhibit some protein kinases. May cancer cell lines including MDA-MB-468 and U87MG can be inhibited by WYE-354 in 0.3–1 mM range.[1]

In-vitro study has proved that WYE-354 can inhibit substrate phosphorylation such as p-4E-BP1 T37/46 and p-Akt S473 by mTORC1 and mTORC2. WYE-354 can reduce Akt downstream function and block the propagation of the cancer cell lines with an IC50 value from sub-micromolar to micromolar range [3]. These effects were consistent with the G1 cell cycle arrest in two cell lines, including rapamycin-sensitive and rapamycin-resistant cells. It is believed to induce apoptosis, repress the global protein synthesis, and down-regulate many angiogenic factors.[3]
