Traumatic brain injury (TBI), often caused by a concussive impact to the head,
affects an estimated 1.7 million Americans annually. With no approved drugs, its
pharmacological treatment represents a significant and currently unmet medical
need. In our prior development of the anti-cholinesterase compound phenserine for
the treatment of neurodegenerative disorders, we recognized that it also
possesses non-cholinergic actions with clinical potential. Here, we demonstrate
neuroprotective actions of phenserine in neuronal cultures challenged with
oxidative stress and glutamate excitotoxicity, two insults of relevance to TBI.
These actions translated into amelioration of spatial and visual memory
impairments in a mouse model of closed head mild TBI (mTBI) two days following
cessation of clinically translatable dosing with phenserine (2.5 and 5.0 mg/kg
BID x 5 days initiated post mTBI) in the absence of anti-cholinesterase activity.
mTBI elevated levels of thiobarbituric acid reactive substances (TBARS), a marker
of oxidative stress. Phenserine counteracted this by augmenting homeostatic
mechanisms to mitigate oxidative stress, including superoxide dismutase [SOD] 1
and 2, and glutathione peroxidase [GPx], the activity and protein levels of which
were measured by specific assays. Microarray analysis of hippocampal gene
expression established that large numbers of genes were exclusively regulated by
each individual treatment with a substantial number of them co-regulated between
groups. Molecular pathways associated with lipid peroxidation were found to be
regulated by mTBI, and treatment of mTBI animals with phenserine effectively
reversed injury-induced regulations in the 'Blalock Alzheimer's Disease Up'
pathway. Together these data suggest that multiple phenserine-associated actions
underpin this compound's ability to ameliorate cognitive deficits caused by mTBI,
and support the further evaluation of the compound as a therapeutic for TBI.
