Dynamic selection of novel vancomycin N-terminal derivatives by resin-bound reversed D-Ala-D-Ala

The most attractive advantage of dynamic combinatorial chemistry (DCC) is that it can screen the compound library as soon as compounds are synthesized. However, it is very difficult to analyze a dynamic combinatorial library with free probes using the state-of-the art analysis technologies. We report herein a method that uses a resin-immobilizing reversed peptide probe to screen vancomycin derivatives and provides a solution to this problem.
