Two-vial, LC-MS identification of ephedrine receptors from a solution-phase dynamic combinatorial library of over 9000 components

Abstract

Reports on dynamic combinatorial chemistry have almost exclusively involved small libraries of 10-100 compounds. We now show how more than 9000 compounds can be screened in a single LC-MS analysis to reveal a series of new receptors that bind ephedrine in water. These results demonstrate the feasibility of screening DCLs that are substantially larger than the solution-phase libraries reported thus far.
