Biochem/physiol Actions
LL-K9-3 is a potent and selective CDK9-cyclin T1 complex degrader (CDK9/CycT1 DC50 = 662/589 nM post 24h treatment, 22RV1 cells) with little potency toward other CDKs (1, 2, 4-7) or cyclins (E1, H, T2). LL-K9-3 exhibits higher antiproliferation activity than SNS-032 against 22RV1 prostate carcinoma cell (IC50 = 95 vs. 384 nM post 5-day treatment). Comparing to SNS-032 and THAL-SNS-032, LL-K9-3 shows stronger inhibition against oncogenic transcription driven by Myc and AR, as well as on several AR intrinsic target genes.
