dCDK9-010
dCDK9-010 is a potent and selective PROTAC degrader of the CDK9/cyclin T complex (P-TEFb), with DC50 values of 0.5 μM (NCI-H226) and 1.4 μM (TC-32), respectively. dCDK9-010 specifically induces proteasome-dependent degradation of the P-TEFb complex (comprising CDK9 and Cyclin T1/T2a/T2b) by recruiting the MDM2 E3 ubiquitin ligase, thereby blocking RNA Pol II CTD phosphorylation to inhibit transcriptional elongation; meanwhile, through competitive occupancy, it blocks MDM2-mediated ubiquitination and degradation of p53, stabilizing p53 tumor suppressor protein levels. dCDK9-010 inhibits tumor cell proliferation and activates Caspase-3/7 activity, thereby inducing apoptosis. dCDK9-010 can be used for research on non-small cell lung cancer and Ewing sarcoma.
