authorities have imposed restrictions to minimize or even stop its use. It has therefore become imperative to identify environmentally benign solvents to replace it. Here we report on a bio derived solvent, γ-valerolactone, for the incorporation of the first aminoacid onto p-alkoxybenzyl alcohol resin in solid-phasepeptidesynthesis. Satisfactory loading values (by a spectrophotometric method) were

This method obtains peptide fragments having ends of specific amino acids from a protein, which does not use an enzyme and thus is associated with minimum contamination. An organic acid represented by a general formula; CF3-(CF2) n-COOH, wherein n is an integer of 0 or larger, is allowed to act on a protein or peptide.
这种方法可以从蛋白质中获得具有特定氨基酸末端的肽片段,无需使用酶,因此污染最小。通式为 CF3-(CF2) n-COOH(其中 n 为 0 或更大的整数)的有机酸可作用于蛋白质或肽。

[graphics]We report highly efficient two-step procedures for the synthesis of 1,3-oxazole-, thiazole-, and imidazole- containing peptides on solid phase from dipeptides composed of C-terminal threonine, serine, cysteine, or diaminopropionic acid by using different cyclodehydration procedures followed or preceded by oxidation. The methods are compatible with Fmoc solid-phase peptide synthesis conditions and with N-Fmoc, N-Boc, N-Cbz, and N-Alloc protecting groups.
