ZLC491
Based on 1 Customer Validation
ZLC491 is an orally active PROTAC degrader that selectively targets CDK12/CDK13 and exhibits certain oral bioavailability. ZLC491 induces cereblon- and proteasome-dependent selective degradation of CDK12 and CDK13. ZLC491 inhibits the transcription and expression of long genes, and mainly acts on a subset of DNA damage response genes. ZLC491 inhibits the proliferation of various triple-negative breast cancer cells. ZLC491 can be used in research related to triple-negative breast cancer.

ZLC491 selectively inhibits the proliferation of triple-negative breast cancer (TNBC) cell lines MDA-MB-231, HCC38 and MDA-MB-436, with IC50 values of 0.62, 0.19 and 0.12 μM after 5 days of treatment, respectively. It exerts a synergistic effect when combined with Cisplatin (HY-17394) or Olaparib (HY-10162). Meanwhile, ZLC491 shows extremely low activity against non-cancer cell lines[1].
ZLC491 (0.01-3 μM; 4-15 h) degrades CDK12 and CDK13 in MDA-MB-231 cells in a dose- and time-dependent manner, with a DC50 of 32 nM and 28 nM, respectively[1].
ZLC491 (0.1-0.5 μM; 48 h) dose-dependently reduces the protein levels of DDR-related proteins ATM, BRCA1 and RAD51 in MDA-MB-231 cells[1].
ZLC491 (60-300 nM; 12 h) potently and concentration-dependently inhibits the transcription of DDR genes in MDA-MB-231 cells, with no significant effect on the non-target gene ROR1[1].

-
Cell Line:HCC38, MDA-MB-436
-
Concentration:0.01-3 μM
-
Incubation Time:15 h
-
Result:Concentration-dependently depleted CDK12 and CDK13 protein levels in both HCC38 and MDA-MB-436 cells, with robust degradation observed at concentrations ≥0.1 μM.
-
Cell Line:MDA-MB-231
-
Concentration:0.1-0.5 μM
-
Incubation Time:48 h
-
Result:Dose-dependently reduced protein levels of DDR-associated proteins ATM, BRCA1, and RAD51, concurrent with degradation of CDK12 and CDK13. Nearly eliminated CDK13 protein levels and significantly reduced ATM, BRCA1, and RAD51 levels relative to DMSO control at 0.5 μM.
-
Cell Line:MDA-MB-231
-
Concentration:60-300 nM
-
Incubation Time:12 h
-
Result:Concentration-dependently suppressed transcription of DDR genes including ATM, ATR, BRCA1, BRCA2, FANCD2, and SMARCC. Showed no significant effect on the control gene ROR1. Reduced ATM, ATR, BRCA1, BRCA2, and FANCD2 mRNA levels to ≤20% of DMSO control at 300 nM.
-
Cell Line:MDA-MB-231
-
Concentration:0.3-7.5 μM (in combination with cisplatin or olaparib)
-
Incubation Time:5 days
-
Result:Demonstrated strong synergistic antiproliferative activity with cisplatin, with CI values of 0.17 for 1.5 μM ZLC491 + 25 μM cisplatin and 0.07 for 7.5 μM ZLC491 + 25 μM cisplatin.
Showed additive to synergistic activity with olaparib, with CI values of 0.90 for 1.5 μM ZLC491 + 25 μM Olaparib and 0.85 for 7.5 μM ZLC491 + 25 μM Olaparib.

Animal Model:CB17SCID mice with Triple-negative breast cancer (female, 6−8 weeks old, orthotopic xenograft model)[1]
-
Dosage:100 mg/kg; 200 mg/kg
-
Administration:p.o.; daily; 5 consecutive days
-
Result:Significantly reduced tumor CDK12 and CDK13 protein levels relative to vehicle control at 100 mg/kg.
Achieved an even greater reduction in tumor CDK12 and CDK13 protein levels at 200 mg/kg.
