Abstract

(Graph Presented) Controlling the drug supply: UV and NMR spectroscopic studies show that drugs such as omeprazole and lansoprazole, popular drugs for the treatment of gastric acid related diseases, are stable for several weeks by using cucurbit[7]uril as a macrocyclic host (see scheme). The drugs are also more rapidly converted into their active forms by an acid-promoted reaction catalyzed by a supramolecular pK_a shift.
