摘要
以Fmoc固相多肽合成法合成片段Pyr-His(Trt)-Trp-Ser(Trt)-Tyr(Bzl)-D-Ser(t Bu)-Leu-OH(2),同时以液相法合成二肽Boc-Arg(Pbf)-Pro-NHEt,并脱除保护基得到H-Arg-Pro-NHEt·2HCl(4),2和4在液相体系中缩合,然后在85%乙酸溶液中,Pd/C催化氢化脱除保护基,得布舍瑞林粗肽,再经制备型RP-HPLC纯化得纯度大于98%的醋酸布舍瑞林,总收率38.7%。
The fragment Pyr-His (Trt)-Trp-Ser (Trt)-Tyr (Bzl)-D-Ser (tBu)-Leu-OH (2) was synthesized by Fmoc solid-phase synthesis,and the dipeptide H-Arg-Pro-NHEt·2HCl (4) was prepared by solution-phase method to give Boc-Arg (Pbf)-Pro-NHEt which was subjected to deprotection.Buserelin acetate was synthesized by the condensation of 2 with 4,followed by deprotection with Pd/C in the 85 % acetic acid,purification by RP-HPLC with an overall yield of 38.7% and an HPLC purity over 98%.
