title: Synthesis and separation of protected tripeptide epimers by RP-HPLC.
abstract: Twenty three epimeric pairs of protected tripeptides of the type Z-Ala-Xaa-Val-OMe have been synthesized by conventional coupling procedures in solution. Optimal conditions for baseline separation of LLL/LDL epimers were found by high-performance liquid chromatography on a RP-18 column with aqueous methanol as mobile phase. The hydrophobic parameters (log kw) were determined for all tripeptides.
