YJ9069
Based on 1 Customer Validation
YJ9069 is a CDK12/CDK13 PROTAC degrader. YJ9069 induces proteasome-dependent degradation of CDK12 and CDK13, and inhibits serine 2 phosphorylation of RNA polymerase II (RNA polymerase II). YJ9069 triggers gene length-dependent transcription elongation defects, reduces the expression of DNA damage response genes, and induces DNA damage, cell cycle arrest and apoptosis. YJ9069 inhibits tumor growth in prostate cancer models. YJ9069 can be used for the research of prostate cancer, Ewing sarcoma and breast cancer.

YJ9069 (0.2-500 nM; 0-15 h) induces dose- and time-dependent degradation of CDK12 and CDK13, and inhibits p-Ser2 of RNA polymerase II, in VCaP prostate cancer cells[1].
YJ9069 (20-200 nM; up to 80 h for VCaP; 0.2-2 μM; up to 100 h for 22Rv1, RWPE, BPH-1) potently and dose-dependently inhibits the proliferation of VCaP and 22Rv1 prostate cancer cells, while exerting no effect on benign RWPE and BPH-1 prostate cells[1].
YJ9069 (for 5 days) exhibits selective cytotoxicity against prostate cancer cells and breast cancer cells (IC50 22.9-2386 nM), with stronger toxicity than that against immortalized benign cells (IC50 >10 μM), and inhibits the viability of AR-positive prostate cancer cells, AR-positive breast cancer cells, and EWS-FLI1-positive Ewing sarcoma cells[1].
YJ9069 (200 nM; 12 h) induces significant DNA damage in VCaP prostate cancer cells[1].
YJ9069 (50 nM; 4-15 h) downregulates key DDR genes (BRCA1, ATM, ATR, FANC1, Rad51) in a time-dependent manner in VCaP prostate cancer cells[1].
YJ9069 (500 nM; 2-12 h) induces gene length-dependent transcriptional downregulation in VCaP prostate cancer cells, with the most pronounced effect on long genes, and triggers time-dependent transcriptional elongation arrest of long genes, while exerting no effect on short genes[1].
YJ9069 (100-500 nM; 15 h) induces dose-dependent subG1 cell cycle arrest in VCaP prostate cancer cells[1].

Cell Line:VCaP prostate cancer cells
-
Concentration:0.2, 1, 5, 20, 100 nM (6 h incubation); 500 nM (time-course incubation)
-
Incubation Time:6 h (dose-response); 0, 1, 2, 4, 8, 15 hr (time-course)
-
Result:Induced dose-dependent degradation of CDK12 and CDK13, with reduced protein levels visible at concentrations as low as 0.2 nM after 6 h.
Triggered time-dependent degradation of CDK12 and CDK13 at 500 nM, with noticeable reduction starting at 2 h and nearly complete degradation by 15 h.
Inhibited phosphorylation of RNA polymerase II at serine 2 in both dose- and time-dependent manners.
