Amyotrophic lateral sclerosis (ALS) is a fatal disease of degeneration of motor neurons. There is no known cure or life extending treatment.
Much recent work has suggested that a possible cause of ALS is constitutive opening of the calcium pore in glutamate sensitive AMPA channels secondary to a failure of RNA editing that would change a crucial glutamate in the channel to arginine.
Here, we point out that the small molecule pharmaceutical acamprosate, usually used as a drug to maintain alcohol abstinence, may block this calcium pore--as do the related molecules endogenous polyamines such as putrescine, cadaverine, spermidine and spermine--and thus might have use in ALS.
