of the indoleamine 2,3-dioxygenase (IDO), a promising therapeutic target for anticancer immunotherapy, a series of 32 phenylthiosemicarbazide derivatives was prepared and their IDO inhibition evaluated. Our study demonstrated that among these derivatives, compound 14 characterized with a 4-cyanophenyl group on the thiosemicarbazide was the more potent IDOinhibitor in this series being endowed with an

proton-coupled anion transporters with pH-switchable behaviour known to be regulated by an imine protonation equilibrium. Previously, chloride/nitrate exchange by PTSCs was found to be inactive at pH 7.2 due to locking of the thiourea anion binding site by an intramolecular hydrogen bond, and switched ON upon imine protonation at pH 4.5. The rate-determining process of the pH switch, however, was not
