Upon oral administration, panulisib inhibits the activity of all four kinases. This prevents PI3K/mTOR and ALK-1-mediated signaling pathways and may lead to the inhibition of cancer cell growth in PI3K/mTOR-overexpressing tumor cells and angiogenesis in ALK-1-overexpressing endothelial cells. Also, by inhibiting DNA-PK, this agent inhibits the ability of tumor cells to repair damaged DNA. The PI3K/mTOR pathway is upregulated in a variety of tumors and plays an important role in regulating cancer cell proliferation, growth, and survival. ALK-1, a member of the transforming growth factor beta (TGF-b) type I receptor family, is overexpressed on endothelial cells in a variety of tumor types and increases endothelial cell proliferation and migration. DNA-PK is activated upon DNA damage and plays a key role in repairing double-stranded DNA breaks."}]
