Mechanism of Action

Targets/IC₅₀/Ki	BCL-XL (Cell-free assay) <0.01 nM(Ki)
In vitro	A-1155463 Dihydrochloride disrupts BCL-XL-BIM but not BCL-2-BIM complexes in cells. A-1155463 kills BCL-XL-dependent Molt-4 cells (EC50=70 nM) but has no measurable cytotoxicity against BCL-2-dependent RS4;11 cells (EC50>5 mM). A-1155463 induces the hallmarks of apoptosis, as evidenced by the release of cytochrome c from mitochondria, caspase activation, and the accumulation of caspase-dependent sub-G0-G1 DNA content in BCL-XL-dependent H146 cells.
In vivo	Following a single 5 mg/kg IP dose of A-1155463 in nontumor bearing SCID-Beige mice, platelet counts fall dramatically as measured at 6 h postdose and then rebound to normal levels within 72 h. Daily Dosing at 5 mg/kg IP to SCID-Beige mice that had been inoculated with BCL-XL-dependent H146 tumor cells for 14 days causes a statistically significant inhibition of tumor growth (maximum tumor growth inhibition = 44%), which is alleviated upon cessation of dosing.
