Trt-Cys(Trt)-OH is a selective dicyclohexyl carbodiimide reagent for the synthesis of amides from carboxylic acids. It is used as an intermediate in the synthesis of glutathione and other nitrogen-containing compounds. Trt-Cys(Trt)-OH reacts with hydrochloric acid to form a salt, which can be saponified to release the desired product. The hydrochloric acid converts the ester into a carboxylic acid, while the amine group on the glycine reacts with the carboxylic acid to form an amide. Trityl is also produced during this reaction, which can be removed by reduction with hydrogen gas and palladium on charcoal.

Bosentan is a potent inhibitor of the uptake of organic anions. It is used in the treatment of pulmonary arterial hypertension and has been shown to be effective against pravastatin-resistant HIV protease inhibitors, such as saquinavir, quinidine, and rosuvastatin. Bosentan inhibits uptake by binding to the transporter protein at a site that does not overlap with the binding site for organic anion substrates. This leads to a change in kinetic parameters for substrates, such as pravastatin and saquinavir. The binding site on bosentan may also be elucidated through monolayer experiments with efflux transporters.
