Biological activities

WYE-125132 is a highly potent, ATP-competitive, and specific mTOR kinase inhibitor. The IC50 value of WYE-125132 is 0.19 nM against mTOR. Consistent with genetic ablation of mTORC2, WYE-125132 targets P-AKT(S473) and AKT function without significantly reducing the steady-state level of the PI3K/PDK1 activity biomarker P-AKT(T308) in cancer cells. Compared with the rapalog temsirolimus/CCI-779, WYE-125132 elicits a substantially stronger inhibition of cancer cell growth and survival, protein synthesis, cell size, bioenergetic metabolism, and adaptation to hypoxia in vitro.[1] In vitro, WYE-125132 treatment also leads to a rapid loss of the phosphorylation at Ser-75 of Maf1.[2] In tumor-bearing mice, oral administration of WYE-125132 has potent single-agent antitumor activity against MDA361 breast, U87MG glioma, A549 and H1975 lung, as well as A498 and 786-O renal tumors. When coadministered with bevacizumab, WYE-125132 achieves a substantial regression of MDA361 and A549 large tumors and causes complete regression of A498 large tumors.[1]

Protocols

WYE-125132 is dissolved in DMSO.[2]
