PARL-IN-1 

PARL-IN-1 is a potent PARL inhibitor with an IC₅₀ value of 28 nM. PARL-IN-1 inhibits PARL and leads to a robust activation of the PINK1/Parkin pathway. PARL-IN-1 promotes PINK1/Parkin-dependent mitophagy^[1].

IC50: 28 nM (PARL)^[1]

PARL-IN-1 (compound 5; 5 nM-20 μM) impedes mitochondrial stress-induced cleavage of PGAM by PARL in cells and inhibits the cleavage of overexpressed human PGAM5 in HEK293T cells in a dose-dependent manner^[1].
PARL-IN-1 (0.1-30 μM; 8 h; HEK293T cells) stabilizes PINK1 and triggers its alternative cleavage and trafficking in living cells^[1].
PARL-IN-1 (5 μM; 22 h; HEK293 T-REx cells) blocks the respiratory chain leading to aberrant reactive oxygen species (ROS) production, activates the PINK1/Parkin pathway^[1].
