R. Traub, J.B. DeWitt, J.F. Welch, D. Newman
1950, Journal of the American Pharmaceutical Association, Scientific Edition (39) 552-555
The antibiotic actidione was found to be highly repellent to laboratory rats and to significantly reduce gnawing attacks upon treated paperboards. Rats refused to accept food or water containing this material even under conditions of acute starvation and died of starvation and thirst rather than accept water containing 1.0 mg. of...
