Palomid 529, also known as P529, is a novel PI3K/Akt/mTOR inhibitor. Palomid 529 (P529) inhibits the TORC1 and TORC2 complexes and shows both inhibition of Akt signaling and mTOR signaling similarly in tumor and vasculature. It was demonstrated that P529 inhibited tumor growth, angiogenesis, and vascular permeability. It retained the beneficial aspects of tumor vascular normalization that rapamycin boasts. However, P529 showed the additional benefit of blocking pAktS473 signaling consistent with blocking TORC2 in all cells and thus bypassing feedback loops that lead to increased Akt signaling in some tumor cells.
