Ezurpimtrostat is an orally bioavailable, quinolone-derived, small molecule inhibitor of palmitoyl-protein thioesterase 1 (PPT1), with potential antineoplastic activity. Upon oral administration, ezurpimtrostat targets and inhibits the activity of PPT1 and induces lysosomal disruption, which results in the inhibition of autophagy and the induction of apoptosis via caspase activation. This may inhibit tumor cell proliferation and tumor growth. PPT1, a lysosomal thioesterase that plays an important role in lysosomal function and autophagy, is overexpressed in certain cancers.
