Bay 11-7082, an inhibitor of NF-κB, induces apoptosis of HTLV-I-infected T-cell lines but only negligible apoptosis of HTLV-I-negative T cells. Bay 11-7082 rapidly and efficiently reduces the DNA binding of NF-κB in HTLV-I-infected T-cell lines and down-regulated the expression of the antiapoptotic gene, Bcl-xL, regulated by NF-κB. Bay 11-7082 selectively inhibits Tax-induced NF-κB activity in a human T-cell line. BAY 11-7082 inhibits NFκB signalling and is recently shown to inhibit the majority of E2 and E3 ligases tested by reacting covalently with the catalytic cysteine residues. Moreover, BAY 11-7082 also inhibits several tyrosine phosphatases by reacting with catalytic Cys residue of these enzymes. NSC 697923 is originally shown to inhibit the E2 ligase Ubc13-Uev1A. BAY 11-7082 inhibits the phosphorylation of IκBα and activation of NF-κB, induces the death of HBL-1 cells. BAY 11-7082 completely suppresses the LPS-stimulated and IL-1-stimulated phosphorylation of the activation loop of IKKβ. BAY 11-7082 acts by inhibiting TNF-α-induced phosphorylation of IκB-α, resulting in decreased NF-κB and decreases expression of adhesion molecules.

BAY 11-7082 (2.5 mg/kg and 5 mg/kg; intratumoral injection; twice-weekly for 21 days ) significantly suppresses tumor growth in a dose-dependent manner.
