WebA prototype for such BZ ligands is imidazenil (IMD), an imidazo-benzodiazepine carboxylic acid derivative that elicits potent anticonvulsant and anxiolytic actions at doses virtually devoid of sedative, cardio-respiratory depressant and amnestic effects, and anticonvulsant tolerance liability. Web1.13 Anhydrides. Acid anhydrides, as their name implies, are formed from the dehydration reaction of two carboxylic acid groups. Anhydrides are highly reactive toward nucleophiles and are able to acylate a number of the important functional groups of proteins and other macromolecules. Upon nucleophilic attack, the anhydride yields one ...
