CKD-712 is a nuclear factor NF-kappa B inhibitor. CKD-712 suppressed MMP-9, but not MMP-2 and other NF-κB-regulated proteins involved in cancer metastasis such as VEGF. CKD-712 induced cell cycle arrest at G2M phase by suppressing cyclin A, cyclin B and C
CDK6 9-IN-1 (compound 66) is a potent dual inhibitor of CDK 6 and CDK 9 that can be administered orally. It exhibits inhibitory activity with IC 50 values of 40.5 nM and 39.5 nM against CDK6 and CDK9, respectively.
CDK7 9-IN-1 is a specific inhibitor of cyclin-dependent kinases 7 9 (CDK7 9). It specifically targets CDK7, while also displaying inhibitory activity against CDK9. CDK7 9-IN-1 demonstrates excellent inhibitory potency against CDK7, with IC50 values of 0.0656 μM and 0.00574 μM without pre-incubation and after 3 hours pre-incubation, respectively. Furthermore, CDK7 9-IN-1 inhibits CDK9 with an IC50 of 2.14 μM after 3 hours pre-incubation. Its application in cancer research makes it valuable for such investigations.
Ibulocydine is a potent CDKinhibitor. Ibulocydine has high activity against Cdk7 cyclin H Mat1 and Cdk9 cyclin T. Ibulocydine inhibited the growth of HCC cells more effectively than other Cdkinhibitors, including olomoucine and roscovitine, whereas ibulocydine as well as the other Cdkinhibitors and BMK-Y101 minimally influenced the growth of normal hepatocyte cells. Ibulocydine induced apoptosis in HCC cells, most likely by inhibiting Cdk7 and Cdk9. In vitro treatment of HCC cells with ibulocydine rapidly blocked phosphorylation of the carboxyl-terminal domain (CTD) of the large subunit of RNA polymerase II, a process mediated by Cdk7 9. Anti-apoptotic gene products such as Mcl-1, survivin, and X-linked IAP (XIAP) are crucial for the survival of many cell types, including HCC. Following the inhibition of RNA polymerase II phosphorylation, ibulocydine caused rapid down-regulation of Mcl-1, survivin, and XIAP, thus inducing apoptosis. Furthermore, ibulocydine effectively ind......
