SH-5

Enzyme inhibitor

This phosphatidylinositol analogue (FWfree-acid = 598.76 g/mol), also known as SH-5, inhibits the proto-oncogenic serine/threonine kinase Akt (protein kinase B), inducing apoptosis. Specific inhibition of Akt by these compounds validates ligand design targeted to the PH domains of crucial signaling proteins, thus providing a unique class of possible cancer therapeutics.
