DHW-221
DHW-221 is a potent orally active dual PI3K/mTOR inhibitor, exhibiting low nanomolar potency against all four Class I PI3K isoforms and mTOR (PI3Kα, IC50 = 0.50 nM; PI3Kβ, IC50 = 1.9 nM; PI3Kγ, IC50 = 1.8 nM; PI3Kδ, IC50 = 0.74 nM; mTOR, IC50 = 3.9 nM). DHW-221 exerts antitumor effects by blocking the PI3K/Akt/mTOR pathway and inducing mitochondrial apoptosis and paraptosis (via Endoplasmic Reticulum (ER) stress and MAPK signaling) and arrests cell cycle, thereby inhibiting cell migration, invasion and angiogenesis. DHW-221 inhibits tumor growth in both the A549/Taxol (HY-B0015) and the HCC827 xenograft mouse models. DHW-221 can be used for non-small cell lung cancer (NSCLC), colon and breast cancer research.
