AZD7762AZD7762 is a potent and selective inhibitor of Chk1 with IC50 of 5 nM in a cell-free assay. It is equally potent against Chk2 and less potent against CAM, Yes, Fyn, Lyn, Hck and Lck. Phase 1. |
E, CAL120 cells were either untreated or pretreated with gemcitabine for 24 hours followed by treatment with AZD7762 and /or MK-1775 for an additional 2 hours (top) or 8 hours (bottom), before lysis. Western blot analysis of Cyclin B1, CDK1 (phospho-Y15 and total) expression, and β-tubulin as loading control. F, induction of the intra–S-phase checkpoint was not affected by WEE1 inhibition. CAL120 cells were pulse-labeled with 10 μmol/L BrdU for 30 minutes, washed (W), and then treated with 1 μmol/L camptothecin (CPT) for 30 minutes. After CPT removal (0 hours), BrdU-labeled S-phase cells (BrdU+ , indicated by boxed area) were monitored at the indicated time points in the absence (iii) or presence of MK-1775 (iv) or AZD7762 as a positive control (v). Control cells (ctr) were not exposed to CPT and cultured in the absence (i) or presence of MK-1775 (ii). Arrowheads indicate delayed S-phase progression. |

MK-1775 and LY2603618 synergize to induce apoptosis in AML cell lines and primary patient samples. U937 and CTS cells were treated for 8 h. Whole cell lysates were subjected to Western blotting and probed with anti-γH2AX, -pCHK1, -p-cdc25c, -p-CDK1, -p-CDK2, -CDK1, or -β-actin antibody. Densitometry measurements, as described in the Materials and methods section, are shown below the corresponding Western blot.

CinobufaginCinobufagin (Cinobufagine), an active ingredient of Venenum Bufonis, inhibits tumor development. Cinobufagin increases ATM and Chk2 and decreases CDC25C, CDK1, and cyclin B. Cinobufagin inhibits PI3K, AKT and Bcl-2 while increases levels of cleaved caspase-9 and caspase-3. Thus, Cinobufagin induces cell cycle arrest at the G2/M phase and apoptosis. |
