    PF-4708671 purchased from MCE. Usage Cited in: J Proteomics. 2016 Feb 2;136:13-24.

    mTORC1 regulates KPNA2 transcription but not S6K1- and 4E-BP1-dependent translation. KPNA2 abundances in response to S6K1 inhibition are detected by Western blot analysis in WT and TSC2−/− MEFs.

    PF-4708671 is a novel cell-permeable inhibitor of S6K1 (p70 ribosomal S6 kinase 1), with a Ki of 20 nM and IC50 of 160 nM. IC50 Value: 160 nM [1] Target: S6K1 PF-4708671 is a novel cell-permeable inhibitor of S6K1, which specifically inhibits the S6K1 isoform with a Ki of 20 nM and IC50 of 160 nM. PF-4708671 prevents the S6K1-mediated phosphorylation of S6 protein in response to IGF-1 (insulin-like growth factor 1), while having no effect upon the PMA-induced phosphorylation of substrates of the highly related RSK (p90 ribosomal S6 kinase) and MSK (mitogen- and stress-activated kinase) kinases. PF-4708671 was also found to induce phosphorylation of the T-loop and hydrophobic motif of S6K1, an effect that is dependent upon mTORC1 (mTOR complex 1). PF-4708671 is the first S6K1-specific inhibitor to be reported and will be a useful tool for delineating S6K1-specific roles downstream of mTOR [1].
