A 44 residue peptide amide corresponding to the entire amino acid sequence of bovine hypothalamic growth hormone releasing factor (bGRF) was synthesized by assembling nine peptide fragments via the azide followed by deprotection with 1M trifluoromethanesulfonic acid-thioanisole in trifluoroacetic acid. Met(O) was reduced by dimethylselenide during the above acid treatment. The synthetic peptide was as active as synthetic human GRF-44-NH2 in vitro assay.
通过
叠氮化物组装九个肽片段,然后用
三氟乙酸中的 1M
三氟甲磺酸-
茴香硫醚去保护,合成了对应于牛
下丘脑生长激素释放因子 (bGRF) 整个
氨基酸序列的 44 残基肽酰胺。在上述酸处理过程中,Met(O)被
二甲基硒化物还原。体外试验中,合成肽的活性与合成人 GRF-44-NH2 相同。
