title: Inhibition of brain synaptosomal uptake of choline by some 2-carboxamidostrychnine derivatives with muscle-relaxant properties.
abstract: Some 2-carboxamido derivatives of strychnine with a peripheral muscle-relaxant effect in vivo and in vitro were tested for their ability to inhibit choline (Ch) uptake into mouse brain synaptosomes. A non-competitive inhibition of the high affinity Ch uptake by strychnine and some of its derivatives was observed.
