NCIt definition : A water soluble, small-molecule prodrug containing the pan-PI3K/mTOR inhibitor LY294002/SF1101
conjugated to the RGD-containing tetra-peptide SF1174 with potential antineoplastic
and antiangiogenic activities. The targeting peptide SF1174 moiety of pan-PI3K/mTOR
inhibitor SF1126 selectively binds to cell surface integrins and, upon cell entry,
the agent is hydrolyzed to the active drug SF1101; SF1101 selectively inhibits all
isoforms of phosphoinositide-3-kinase (PI3K) and other members of the PI3K superfamily,
such as the mammalian target of rapamycin (mTOR) and DNA-PK. By inhibiting the PI3K
signaling pathway, this agent may inhibit tumor cell and tumor endothelial cell proliferation
and survival.;
