The intensity of effects produced by dihalopyruvic acids was greater than that produced by the monohalopyruvic acids. Of the halopyruvic acids studied, dibromopyruvic was the most potent compound in production of salivation, lacrimation and analgesia; in addition, it exhibited the most marked anticholinesterase activity. The toxicity of these compounds was related, in part, to their inhibition of oxidation of substrates of the citric acid cycle.
