The solid phase synthesis of an amidated somatostatin analogue based on the principle of differentiated acidolysis is described. The acid labile and smoothly cleavable t-Bumeoc moiety (1% TFA/DCM) is used for temporary Nα-protection of D- and L-amino acids and [4-[[[9H-fluoren-9-yl-methoxycarbonyl]amino](4-methoxyphenyl)methyl]-2-methylphenoxy]acetic acid, attached to an aminomethylated polystyrene resin is used as acid sensitive linker of the solid carrier which releases the peptide in its amide form by treatment with TFA. Its preparation is described in detail.
一种基于差异化酸解原理的酰化生长抑素类似物的固相合成方法被描述。酸敏感且易于裂解的t-Bumeoc基团(1%三氟乙酸/二氯甲烷)被用作D-和L-氨基酸以及[4-[[[9H-芴基-9-基甲氧羰基]氨基](4-甲氧基苯基)甲基]-2-甲基苯氧基]乙酸的临时Nα-保护基,连接到氨甲基化聚苯乙烯树脂上的固相载体上,作为固相载体的酸敏感连接剂,通过三氟乙酸处理释放出肽类物质的酰胺形式。其制备过程被详细描述。
