JS6 is a Bcl3:NF-kB p50 protein-protein interaction (PPI) inhibitor that effectively suppresses Bcl3-dependent intracellular NF-kB activity (IC50 = 45/159 nM using Bcl3-overexpressing MDA-MB-231/HEK293; IC50 = 710 nM using HEK293 overexpressing Bcl3 and NF-kB p52). JS6 prevents enhanced MDA-MB-231 migration upon Bcl3 overexpression in cultures (IC50 = 310 nM), and effectively suppresses primary tumor growth as well as secondary tumor colonisation in vivo (3.5-10 mg/kg/d i.p. mice with MDA-MB-436 or 4T1.2 murine carcinoma xenograft) without overt systemic toxicity.

The development of antimetastatic drugs is an urgent healthcare priority for patients with cancer, because metastasis is thought to account for around 90% of cancer deaths. Current antimetastatic treatment options are limited and often associated with poor long-term survival and
