Abstract

16 ADT carboxylate esters were prepared and tested for their chemical characteristics, stability, bioavailability, potency and toxicity. Considering the good bioavailability, 3a was selected for the pharmacology test, and the result showed that the potency of 3a was remarkably higher than that of ATT. Additionally, 3a was also chosen for the acute toxicity test. The result indicated that the prodrug 3a was more safer than ATT. The study suggested the feasibility to improve the bioavailability of ATT by using prodrug strategy.
