ZSTK3744 free base
ZSTK3744 free base is an aryl hydrocarbon receptor (AhR) agonist. ZSTK3744 free base directly binds to AhR, upregulates the expression of AhR target genes including CYP1A1, CYP1B1 and TIPARP, and mediates cell growth inhibitory activity in triple-negative breast cancer cells. ZSTK3744 free base induces apoptosis in triple-negative breast cancer cells. ZSTK3744 free base exhibits anti-tumor activity and can be used in the research of chemoresistant triple-negative breast cancer.

Biological Activity
ZSTK3744 free base (0.1-1000 nM; 72 h) (compound 12) potently inhibits the growth of MDA-MB-468 triple-negative breast cancer (TNBC) cells, with an IC50 of 0.87 nM[1].
ZSTK3744 free base (0.1-1000 nM; 72 h) potently inhibits the growth of Doxorubicin (HY-15142A)-resistant MDA-MB-468/AR triple-negative breast cancer (TNBC) cells, with an IC50 of 0.92 nM[1].
ZSTK3744 free base (0.1-1000 nM; 72 h) inhibits the growth of Paclitaxel (HY-B0015)-resistant MDA-MB-468/PR triple-negative breast cancer (TNBC) cells with an IC50 of 23.54 nM[1].
ZSTK3744 free base (1-24 h) upregulates the mRNA expression of CYP1A1 and TIPARP in MDA-MB-468 triple-negative breast cancer (TNBC) cells in a time-dependent manner, with significant induction observable as early as 1 hour after treatment[1].
ZSTK3744 free base (24 h) induces apoptosis in MDA-MB-468 TNBC cells, and its cell growth inhibitory activity is mediated at least partially via the caspase-dependent apoptotic pathway[1].
ZSTK3744 free base (0.1-1000 nM; 72 h) potently inhibits the growth of MDA-MB-453 triple-negative breast cancer (TNBC) cells, with an IC50 of 1.14 nM[1].
ZSTK3744 free base (0.1-1000 nM; 72 h) potently inhibits the growth of DU4475 triple-negative breast cancer (TNBC) cells, with an IC50 of less than 0.50 nM[1].
ZSTK3744 free base (0.1-1000 nM; 72 h) exerts no significant inhibitory effect on the growth of Hs578T TNBC cells, with an IC50 >500 nM[1].
