The octapeptide H-Glu-Ser-Leu-Ser-Ser-Ser-Glu-Glu-NHMe.CF3CO2H and its five shorter peptide congeners (from tripeptide to heptapeptide ) were prepared in high yield and purity by the Boc mode of solution phase peptide synthesis followed by palladium- catalysed hydrogenolytic deprotection of the six protected peptides in 50% CF3CO2H/CH3CO2H solution. The analysis of the six peptides by 13C n.m.r. spectroscopy and C18 reversed-phase chromatography suggested that a structural arrangement commenced at the hexapeptide stage and was considered to be due to the formation of a β-turn conformation.

Solution Phase Synthesis

The solution phase synthesis of N-protected amino acids and peptides has been achieved through GAP chemistry by avoiding disadvantages of the solid-phase-peptide synthesis (SPPS) and liquid-phase-peptide synthesis. The environmentally friendly GAP synthesis can substantially reduce the use of solvents, silica gels, energy and manpower.

The PTyr (O-phosphotyrosine) pentapeptide H-Asn-Glu-Tyr(PO3H2)-Thr-Ala-OH.HO2CCF3, which is a naturally occurring sequence from the autophosphorylated Rous sarcoma virus pp60V-SrC, was prepared in high yield by the use of Boc-Tyr(PO3Me2)-OH in the Boc mode of solution-phase peptide synthesis. The protected pentapeptide, Z-Asn-Glu(OBzl)-Tyr(PO3Me2)-Thr(Bzl)-Ala-OBzl, was deprotected by a two-stage procedure which involved initial palladium-catalysed hydrogenolysis followed by the removal of the phosphate methyl groups by the use of one of the following treatments: (A) 10% bromotrimethylsilane/acetonitrile, (B) 1 M bromotrimethylsilane/thioanisole in trifluoroacetic acid, or (C) trifluoromethanesulfonic acid/trifluoroacetic acid/dimethyl sulfide/m-cresol.
