    TAS0612, a novel RSK, AKT, and S6K inhibitor, exhibits antitumor effects in preclinical tumor models. (PubMed, Mol Cancer Ther)
    Additionally, TAS0612 demonstrated the persistence of blockade of downstream growth and anti-apoptotic signals, despite activation of upstream effectors in the signaling pathway and FoxO-dependent re-expression of HER3. In conclusion, TAS0612 with RSK/AKT/S6K inhibitory activity may provide a novel therapeutic strategy for cancer patients to improve clinical responses and overcome resistance mechanisms.

    Triple targeting of RSK, AKT, and S6K as pivotal downstream effectors of PDPK1 by TAS0612 in B-cell lymphomas. (PubMed, Cancer Sci)
    At the molecular level, TAS0612 caused significant downregulation of MYC and mTOR target genes while inducing the tumor suppressor TP53INP1 protein in these cell lines. These results prove that the simultaneous blockade of RSK2, AKT, and S6K, which are the pivotal downstream substrates of PDPK1, is a novel therapeutic target for the various disease subtypes of BCLs and line up TAS0612 as an attractive candidate agent for BCLs for future clinical development.

    Targeting phosphorylation of Y-box binding protein YBX1 by TAS0612 and everolimus in overcoming antiestrogen resistance. (PubMed, Mol Cancer Ther)
    Here we found that increased expression of pYBX1 was accompanied by acquired resistance to antiestrogens, fulvestrant and tamoxifen. TAS0612 also demonstrated antitumor effect against triple-negative breast cancer in vivo. Taken together our findings suggest that pYBX1 represents a potential therapeutic target for treatment of antiestrogen resistant and progressive breast cancer.
