N,N-Dimethyl-2-chloro-2-phenylethylamine

"N","N"-Dimethyl-2-chloro-2-phenylethylamine is chemical compound that irreversibly inhibits the acetylcholinesterase. This compound, when dissolved water, decomposes into a highly reactive aziridinium ion, "N","N"-dimethyl-2-phenylaziridinium (DPA). DPA binds to the anionic site of acetylcholinesterase, where it alkylates and irreversibly inhibits the enzyme.
