使用固相肽合成法生产
比伐卢定的方法:a) 将Fmoc-Asn(Trt)-Gly-OH与Asp(OtBu)11-Phe12-Glu(OtBu)13-Glu(OtBu)14-Ile15-Pro16-Glu(OtBu)17-Glu(OtBu)18-Tyr(tBu)19-Leu20-Resin的肽
树脂缩合;b) 去除Fmoc-;c) 将Fmoc-Gly-Gly-Gly-Gly-OH与肽
树脂缩合;d) 分别将Pro、Arg、Pro和Phe与肽
树脂从C端到N端缩合,得到Boc-D-Phe1-Pro2-Arg(Pbf)3-Pro4-Gly5-Gly6-Gly7-Gly8-Asn(Trt)9-Gly10-Asp(OtBu)11-Phe12-Glu(OtBu)13-Glu(OtBu)14-Ile15-Pro16-Glu(OtBu)17-Glu(OtBu)18-Tyr(tBu)19-Leu20-Resin的肽
树脂;e) 在裂解剂的存在下,将肽与肽
树脂分离,得到以
化学式VI表示的
比伐卢定。该方法成本低廉,产生的
比伐卢定纯度高。
