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.

Concentration:

2 μM
Incubation Time:

4, 8, 12, and 24 h

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
