MRT00033659 是一种有效的广谱激酶抑制剂，抑制 CK1 (对 CK1δ:IC50=0.9 µM) 和 CHK1 (IC50=0.23 µM)。MRT00033659 是一种吡唑并吡啶类似物，可以诱导 p53 途径活化和 E2F-1 不稳定。
MRT00033659 is a potent broad-spectrum kinase inhibitor of CK1 (IC50=0.9 µM for CK1δ) and CHK1 (IC50=0.23 µM). MRT00033659, a pyrazolo-pyridine analogue, induces p53 pathway activation and E2F-1 destabilisation[1].
MRT00033659 (5-40 µM; 48 hours) is sufficient to significantly reduce cell number of 5 µM[1]. MRT00033659 (1-80 µM; 48 hours) induces substantial cell death from 5 µM[1]. MRT00033659 (0.2-80 µM; 48 hours) induces a robust and sustained stabilisation of p53, MDM2 and p21 proteins, as well as E2F-1 destabilisation from 0.2 µM to 5 µM[1]. MRT00033659 does not inhibit p38α MAPK[1]. Cell Viability Assay[1] Cell Line: A375 cells
