Catalpol, an iridoid glucoside, has been reported to inhibit apoptosis of neuron and endothelial cells; the pretreatment of H9c2 cells with catalpol can be against H 2 O 2 -induced apoptosis, and the protective effect of catalpol involves the mitochondrial-dependent caspase pathway and is associated with increased Bcl-2 and decreased Bax expression.[1]
Catalpol has the neuroprotective effects of in lipopolysaccharide (LPS)-induced inflammatory models, it can prevent mesencephalic neuron death and ameliorate cognitive ability animals; catalpol can exert inhibitory effects on the inflammatory reaction in astrocytes and that inactivation of NF-κB could be the major determinant for its anti-inflammatory mechanism, therefore, it may potentially be a highly effective therapeutic agent in treating neurodegenerative diseases associated with inflammation.[2]
Catalpol exerts the most significant cytoprotective effect on astrocytes by suppressing the production of free radicals and elevating antioxidant capacity.[3]
Catalpol can increase presynaptic proteins and up-regulate relative signaling molecules in the hippocampus of the aged rats, it seems to indicate that catalpol might ameliorate age-related neuroplasticity loss by “normalizing” presynaptic proteins and their relative signaling pathways in the aged rats.[4]
