Ditran (JB-329) is an anticholinergic drug mixture, related to the chemical warfare agent 3-Quinuclidinyl benzilate (QNB). Ditran is composed of a mixture of 70% 1-ethyl-2-pyrrolidinylmethyl-alpha- phenylcyclopentylglycolate and 30% 1-ethyl-3-piperidyl-alpha-phenylcyclopentylglycolate. These compounds are structural isomers and have very similar pharmacological properties. The piperidine compound is the more potent of the two and the reason the mixture was used was because of ease of manufacture, however it is also possible to make the piperidine compound in its pure form, so there were ultimately two forms of Ditran used in research, the original 70/30 mix, and "Ditran-B", the pure piperidine compound. Ditran was developed during chemical weapons research in an attempt to produce non-leth
