NEO214 is an autophagy inhibitor and a covalent conjugate of the PDE4 inhibitor Rolipram and perillyl alcohol . It has anti-cancer activity and blood-brain barrier (BBB) permeability. Over sex. NEO214 prevents autophagy-lysosome fusion, thereby blocking autophagic flux and triggering glioma cell death. The process involves mTOR activation, andTFEB(Transcription Factor EB) aggregation. NEO214 inhibitionMacroautophagy/autophagy in glioblastoma cells has the potential to overcome chemotherapy resistance in glioblastoma.
