Abstract

γ-Butyrobetaine, in comparison with its methyl ester, γ-carbomethoxypropyltrimethyl-ammonium bromide, is biologically inert. When injected into mice and insects or assayed on the frog's rectus abdominis muscle, γ-carbomethoxypropyltrimethyl-ammonium bromide has pharmacological properties resembling those of acetylcholine. Although reported to be present in rat brain during the convulsions induced by dieldrin poisoning, γ-butyrobetaine has not been found in the nervous tissue of the roach after treatment with dieldrin.
