...Barbiturates therefore promote entry of GABA-activated channels into a long-lived open state, whereas [benzodiazepines] increase only the frequency of channel opening into the initial open state. These mechanistic studies reveal interesting details of the changes in channel gating caused by barbiturates but as yet have yielded no insights into the molecular sites of action. An additional interesting effect of barbiturates is direct gating of the channels, i.e., the barbiturates may open the channel even in the absence of GABA. This usually occurs at significantly higher concentrations than those that potentiate the actions of GABA; these concentrations also are generally higher than those required for clinically effective anesthesia.
Barbiturates were synthesized in 1864 by Adolf von Baeyer, though the synthetic process was developed and perfected by the French chemist Edouard Grimaux in 1879
