Overview

Information

HO-3867, an analog of curcumin, is a selectiveSTAT3inhibitor that inhibits its phosphorylation, transcription, and DNA binding without affecting the expression of other active STATs. HO-3867 inducesapoptosis.

Targets

STAT3

In vitro

HO-3867 produces significant cytotoxicity in A2780 and other tested ovarian cancer cell lines, with less toxic to noncancerous ovarian surface epithelial cells. HO-3867 induces G(2)-M cell cycle arrest in A2780 cells and promotes apoptosis by caspase-8 and caspase-3 activation. HO-3867 blocks the JAK/STAT3 pathway in human ovarian cancer cell lines.

In vivo

HO-3867 (100 ppm p.o.) inhibits the growth of ovarian cancer xenograft tumor in mice without any apparent signs of toxicity, and also results in inhibition of pSTAT3 as well as downregulation of the STAT3-targeting proteins. HO-3867 sensitizes cisplatin-resistant ovarian carcinoma through STAT3 inhibition. HO-3867 (100 ppm p.o.) also attenuates left-heart-failure-induced pulmonary hypertension by decreasing oxidative stress and increasing PTEN expression in the lung of rats.
