LC28
LC28 is a STAT3 inhibitor with a human STAT3 Ki of 3.92 μM. LC28 targets the DNA-binding domain of STAT3, inhibits STAT3-DNA binding, and suppresses STAT3 signaling. LC28 induces apoptosis and suppresses survival of cisplatin-resistant ovarian cancer cells. LC28 can be used for the research of Cisplatin (HY-17394)-resistant ovarian cancer.

In Vitro
LC28 (0.01-1000 μM; 72 h) suppresses survival of H1299 non-small cell lung cancer cells with an IC50 of 8.1 μM after 72 h of treatment[1].
LC28 (0.01-1000 μM; 72 h) suppresses survival of SKOV3 ovarian cancer cells with an IC50 of 3.7 μM and cisplatin-resistant SKOV3/DDP ovarian cancer cells with an IC50 of 14.7 μM after 72 h of treatment[1].
