Coluracetam (INN ) (code name BCI-540 ; formerly MKC-231 ) is a nootropic agent of the racetam family.[ 1] It was initially developed and tested by the Mitsubishi Tanabe Pharma Corporation for Alzheimer's disease . After the drug failed to reach endpoints in its clinical trials it was in-licensed by BrainCells Inc for investigations into major depressive disorder (MDD), which was preceded by being awarded a "Qualifying Therapeutic Discovery Program Grant" by the state of California.[ 2] Findings from phase IIa clinical trials have suggested that it would be a potential medication for comorbid MDD with generalized anxiety disorder (GAD).[ 3] [dead link ] BrainCells Inc is currently[when? ] out-licensing the drug for this purpose.[ 4] [full citation needed ] It may also have potential use in prevention and treatment of ischemic retinopathy and retinal and optic nerve injury.[medical citation needed ]
Coluracetam has been shown to reverse the loss of choline acetyltransferase production in the medial septal nucleus of rats exposed to phencyclidine (PCP), and is considered a potential therapeutic drug for schizophrenia .[ 5]
Mechanism of action
Coluracetam enhances high-affinity choline uptake , which is the rate-limiting step of acetylcholine (ACh) synthesis . Studies have shown coluracetam to improve learning impairment on a single oral dose given to rats which have been exposed to cholinergic neurotoxins . Subsequent studies have shown that it may induce long-lasting procognitive effects in cholinergic neurotoxin-treated rats by changing the choline transporter regulation system.[ 6]
