Due to its mechanism of action, NGX267 may be simultaneously effective in treating the memory and cognitive disturbances experienced by Alzheimer's patients and in reducing the creation of neurotoxic proteins, thereby delaying disease progression.
Mechanism of action
NGX267 has been shown to stimulate M1 receptors in a fashion analogous to acetylcholine, a neurotransmitter essential for memory and cognitive function that is depleted when neurons, or brain cells, degenerate. The M1 receptor plays an important role in memory and cognitive processing. Its activation has also been linked to decreases in two biochemical processes, AB production and tau protein phosphorylation, both of which are involved in the creation of the neurofibrillary tangles and amyloidplaques that are major histopathological hallmarks of Alzheimer's disease. By selectively enhancing M1 cholinergic neurotransmission in the brain, NGX267 may offer advantages over current therapies for Alzheimer's disease due to the relative preservation of this system in patients who are clinically symptomatic.
The muscarinic acetylcholine receptor mediates various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Primary transducing effect is Pi turnover.
