描述 | Silmitasertib (CX-4945) leads to cell-cycle arrest and selectively induces apoptosis in cancer cells compared to normal cells. This action is associated with the attenuation of PI3K/Akt signaling and the antiproliferative activity of Silmitasertib is linked to the expression levels of the CK2α catalytic subunit[1]. When combined with PS-341, Silmitasertib prevents leukemic cells from initiating a functional unfolded protein response (UPR) to counteract PS-341-induced proteotoxic stress in the ER lumen. It also reduces the expression of the pro-survival ER chaperone BIP/Grp78[2]. Silmitasertib induces cytotoxicity and apoptosis and exerts antiproliferative effects in hematological tumors. It achieves these effects by downregulating CK2 expression and inhibiting the activation of CK2-mediated PI3K/Akt/mTOR signaling pathways[3]. |
体内研究 | Administered orally at doses of 25 or 75 mg/kg, Silmitasertib is well-tolerated and shows significant antitumor activity in murine xenograft models. This efficacy is accompanied by reductions in the biomarker phospho-p21 (T145)[1]. |

It achieves these effects by downregulating CK2 expression and inhibiting the activation of CK2-mediated PI3K/Akt/mTOR signaling pathways[3]. |
作用机制 | CX-4945 acts as an ATP-competitive inhibitor of both isoforms of CK2 catalytic subunits, CK2α and CK2α’, directly blocking the phosphorylation of Akt at Serine 129 in PI3K/Akt signaling pathway. |
