Human gastric juice contains protein BPC, which exhibits a wide range of biological activities. The 15-amino acid fragment (BPC 157) and its analogues were synthesized using SPPS on a preloaded Boc–Val-HYCRAMTM polymeric resin (the combination of Boc- and Fmoc-chemistry was used) and a preloaded Fmoc-Val-SASRINTM polymeric resin (the Fmoc-chemistry was used). Yields, chromatographic purities and costs for synthesis of equal mmolar amounts of compounds on both polymeric resins were compared.
