Good day, i lately discovered these two chemical substances:
* ZDCM-04, wich appears to be a prodrug for DOC and [theophylline](https://en.wikipedia.org/wiki/Theophylline). [https://upload.wikimedia.org/wikipedia/commons/e/e2/ZDCM-04_structure.png](https://add.wikimedia.org/wikipedia/commons/e/e2/ZDCM-04_structure.png)
* Fenethylline, which is a prodrug for amphetamine and [theophylline](https://en.wikipedia.org/wiki/Theophylline). [https://en.wikipedia.org/wiki/Fenethylline](https://en.wikipedia.org/wiki/Fenethylline)
1. Are you aware any comparable chemical substances ?
2. Do you suppose comparable compounds are synthesizable: like **methylenedioxyamphetaminoethyltheophylline** possibly ? and would these be good RCs ?
