Metastasis is the major cause of death in cancer. Most therapies currently in the clinic aim to eradicate primary tumor, but do not have ideal effects on metastasis. The lack of effective therapy in metastasis prevention and treatment results in high mortality rate in cancer patients with advanced diseases. Here we report the oxidized glutathione small molecule compound NOV-002 reduces cancer cell invasion in vitro and metastasis in an animal model in combination with chemotherapy drug gemcitabine. NOV-002 regulates cell signaling pathways by suppressing ErbB2 and PI3K phosphorylation and subsequent inhibition of Akt and RhoA activation. Our results suggest that NOV-002 affects cell signaling pathways that are critical for invasion and metastasis and can potentially be effective in metastasis treatment in combination of other chemotherapies.
