triciribine phosphate
The phosphate salt of the synthetic, cell-permeable tricyclic nucleoside triciribine with potential antineoplastic activity. Triciribine inhibits the phosphorylation, activation, and signalling of Akt-1, -2, and -3, which may result in the inhibition of Akt-expressing tumor cell proliferation. Akts are anti-apoptotic serine/theronine-specific protein kinases that phosphorylate and inactivate components of the apoptotic machinery, including Bcl-xL/Bcl-2-associated death promoter (BAD) and caspase 9. Check for active clinical trials using this agent. (NCI Thesaurus)
