How to use

In Vitro:

HO-3867 exhibit minimal toxicity toward noncancerous cells and tissues but induce apoptosis in ovarian cancer cells. HO-3867 inhibit cell migration/invasion and survival by inhibiting STAT3 phosphorylation. BRCA-mutated ovarian cancer cells treated with HO-3867 exhibited a significant degree of apoptosis with elevated levels of cleaved caspase-3, caspase-7 and PARP. HO-3867 shows good antitumor activity at the concentration of 2 μmol/L in PANC-1 and BXPC-3 cells. Importantly, it is also found that HO-3867 treatment significantly induced reactive oxygen species (ROS) production in human pancreatic cancer cell lines, inducing PANC-1 and BXPC-3 cells.
