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

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].
