ZJC-11

ZJC-11 is a CDK7 inhibitor with an IC₅₀ of 5.4 nM. ZJC-11 binds covalently to CDK7, inhibits CDK7-dependent phosphorylation of RNAPII at Ser2, Ser5 and Ser7 sites, and suppresses transcriptional processes. ZJC-11 acts as a cell cycle inhibitor, inhibits the G2/M checkpoint pathway, and induces G2/M phase arrest. ZJC-11 induces DNA damage-driven cellular senescence and cell death. ZJC-11 exhibits antiproliferative activity against triple-negative breast cancer both in vitro and in vivo. ZJC-11 can be used for research related to triple-negative breast cancer

For research use only. We do not sell to patients.

In Vitro

ZJC-11 (1 μM; 4 h) selectively binds to endogenous CDK7 in MDA-MB-231 cells and enhances the thermal stability of CDK7 compared with CDK1, CDK2 and CDK9^[1].
ZJC-11 (0-10000 nM; 24-72 h) potently inhibits the proliferation of triple-negative breast cancer cell lines (MDA-MB-231, CAL-148, MDA-MB-468, BT-549, MFM223), with IC₅₀ values ranging from 0.306 to 2.41 μM. It shows weak activity against the estrogen receptor-positive (ER+) breast cancer cell line ZR-75-1, and exhibits extremely low toxicity toward normal cell lines MCF10A and RAW264.7^[1].
ZJC-11 (0-500 nM; 14 days) inhibits colony formation of MDA-MB-231 and MDA-MB-468 cells in a dose-dependent manner, but exerts almost no effect on ZR-75-1 ER⁺ breast cancer cells^[1].
ZJC-11 (0-500 nM; 48 h) dose-dependently increases the proportion of dead cells in MDA-MB-231 and MDA-MB-468 cells^[1].
ZJC-11 (0-1000 nM; 6-48 h) dose-dependently inhibits the phosphorylation of Ser2, Ser5 and Ser7 sites on RNAPII CTD in MDA-MB-231 and MDA-MB-468 cells^[1].
ZJC-11 (0-500 nM; 48 h) induces DNA damage-driven therapy-induced senescence and senescence-associated secretory phenotype in MDA-MB-231 and MDA-MB-468 cells^[1].
ZJC-11 (0-1000 nM; 48 h) induces G2/M cell cycle arrest in MDA-MB-231 and MDA-MB-468 cells by downregulating cyclin B1 and phosphorylated CDK1^[1].
ZJC-11 (500 nM; 1 h pre-incubation, 12 h DOX incubation) alleviates DOX (HY-15142A)-induced cardiotoxicity in H9c2 and HL-1 cardiomyocytes by preserving mitochondrial function, reducing apoptosis, and restoring p-CDK1 levels^[1].

Help & FAQs

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.
