General description

A cell-permeable benzoquinone compound that exhibits antitumor properties. Specifically antagonizes XIAP (X-linked inhibitor of apoptosis)-mediated inhibition of caspase-9 activation by directly targeting the Smac and caspase-9 binding domain BIR3 (IC₅₀ = 4.1 µM in a competitive binding assay with Smac peptide). Selectively induces caspase-9-mediated apoptosis in prostate cancer cells with high levels of XIAP (IC₅₀ = 3.7 and 5.7 µM for PC-3 and LnCap, respectively), while exhibiting much less effect towards cells with low level XIAP (IC₅₀ = 19.3 and 20.1 µM for WI-38 and PrEC, respectively). Also shown to sensitize XIAP overexpressing Jurkat cells to Etoposide -induced apoptosis. A non-competitive PCAF (p300/CBP associated factor)-specific lysine acetyltransferase (KAT) inhibitor (IC₅₀ = 7.2 µM).
