16 ADT carboxylate esters were prepared by means of esterification and these compounds were expected to increase the bioavailability of 4-hydroxyanehole trithione. In vivo studies showed that ADT concentration of 3a in plasma was much higher than that of ATT during 120min. Compound 3a could reach blood peak values of ADT at 660.6 ng/mL which was about 14 times of that by ATT. Additionally, the acute toxicity assay indicated high safety of ...
