Description

含有环状酰亚胺的肽产物的合成
本发明涉及合成包含至少一个环状酰亚胺基团的肽产物的方法。此外,本发明涉及基本上不含降解产物的包含至少一个环状酰亚胺基团的肽产物。该肽产物可以用作用于质量控制药物肽的参比物质,具体地为用于质量控制GLP-1激动剂如毒蜥外泌肽(exendinpeptide)的参比物质。
使用熟知的重组DNA和化学固相合成方法,已经合成了用于制药的若干蛋白和肽。然而这些蛋白和肽的生产通常导致大量不期望的合成副产物。这在它们通过固相合成而产生时尤其如此。随着肽/蛋白长度的增加,导致了合成步骤的增加,这些副产物可占粗产物的50至70%。
副产物可能包括含有环状酰亚胺基团如天冬酰亚胺或戊二酰亚胺的肽产物。这样的环状酰亚胺基团生成于固相合成期间或之后,例如,当从固相载体除去肽时或当配制或存储肽组合物时(Geiger&Clarke,J.Biol.Chem.262(1987),785-794;Hekmanetal.,JPharm.Biomed.Anal.20(1999),763-772;Lindner&Helliger,Exp.Gerontol.36(2001),1551-1563;Aswadetal.,J.Pharm.Biomed.Anal.21(2000),1129-1136;Ritz-Timme&Collins,AgeingRes.Rev.1(2002),43-59;Mergleretal.,J.Pept.Sci.9(2003),36-46;Mergleretal.,J.Pept.Sci.9(2003),518-526:Mergleretal.,J.Pept.Sci.1(2005),650-657;Cebrianetal.,J.Pept.Res.62(2003),238-244;DeBonietal.,J.Chrom.A.1022(2004),95-102;和Houchinetal.,J.Contr.Release112(2006),111-119)。
含有环状酰亚胺基团的肽产物的靶向合成是未知的。过去,天冬酰亚胺或戊二酰亚胺已经通过“强制降解”方法产生,其中含有氨基酸Asp或Asn的肽经历降解条件,例如在pH4或pH8条件下和任选在约40至约50℃的升高的温度下搅拌1-2天。但是,这些方法具有以下缺点:除了所需产物之外,得到了大量的其他降解产物。具体地,环状酰亚胺基团会经历进一步的反应,例如外消旋化,形成异天冬氨酸肽,从Asn转化成Asp,亲核试剂打开天冬酰亚胺,肽键断开,等。因此,在实施强制降解之后,常常难以将所需的环状酰亚胺产物从含肽化合物的复杂混合物中纯化出来。
为了克服这些在制造和纯化环状酰亚胺肽产物中的困难,本发明人研发了用于含环状酰亚胺的肽的靶向合成。
该方法以肽利西拉来(AVE0010),即一种具有44个氨基酸长度的GLP-1激动剂,作为示例进行显示。利西拉来的氨基酸序列示于SEQIDNO:1中:
H-G-E-G-T-F-T-S-D-L-S-K-Q-M-E-E-E-A-V-R-L-F-I-E-W-L-K-N-G-G-P-S-S-
G-A-P-P-S-K-K-K-K-K-K-NH2
利西拉来通过化学固相合成方法来制备。
天冬酰亚胺可以从肽序列-Asn-X-或-Asp-X-(其中X表示C-末端邻接的氨基酸残基)形成。在前一种情况中,环化涉及除去氨(NH3),在后一种情况中,涉及除去水(H2O)。在图1中,显示了在AVE0010中即在位置-Asn(28)-Gly(29)-和Asp(9)-Leu(10)上形成天冬酰亚胺。所得产物分别标记为[Asp(9)-H2O]-AVE0010和[Asn(28)-NH3]-AVE0010。原则上,相同的反应导致形成从氨基酸Gln或Glu形成戊二酰亚胺。
本发明人现在发现,在合成肽期间在偶联步骤中当在需要形成环状酰亚胺基团的预定位置上使用具有不受保护的COOH或CONH2侧链的氨基酸构造块(buildingblocks)例如Asp、Asn或Glu、Gln时,靶向合成环状酰亚胺基团是可行的。在不需要形成环状酰亚胺基团的其他位置上,可以在合成中使用具有受保护的COOH或CONH2侧链的氨基酸构造块。通过增加偶联时间和重复添加偶联试剂,环状酰亚胺基团可以几乎定量的产率得到。因此,本发明允许在肽序列的预定位置选择性形成环状酰亚胺基团,而不影响可能易于形成环状酰亚胺基团的肽序列的其他位置。
在图2中显示了形成天冬酰亚胺基团。将具有未经保护的羧基侧链的受氨基保护(例如Fmoc)的Asp构造块在偶联试剂的存在下添加至具有游离氨基的载体树脂连接的肽衍生物。天冬酰亚胺基团的形成通过将偶联时间增加至≥1天并重复添加偶联试剂而得到促进。肽合成的其他步骤,即,在先和/或后续步骤,可以在标准条件下进行。但是,应当避免使用用于断开Fmoc保护基的哌啶,因此这会导致天冬酰亚胺环的开环。
本发明的方法实现了以高产率和纯度靶向合成环状酰亚胺肽产物。这些肽产物可以例如用作质量控制药物肽产物如利西拉来的参比物质。

此外,本发明应通过下述实施例来进行更详细地阐述,该实施例描述了含有环状酰亚胺基团的肽[Asp(9)-H2O]-AVE0010的合成、色谱纯化和分析表征。
实施例
1.合成Asp(9)-H2O]-AVE0010
[Asp(9)-H2O]-AVE0010为合成药物肽产物AVE0010的副产物。其如下产生:氨基酸Asp(9)的侧链在除去水的条件下形成具有邻接氨基酸Leu(10)的N-原子的天冬酰亚胺。
[Asp(9)-H2O]-AVE0010的氨基酸序列如下:
H-His-Gly-Glu-Gly-Thr-Phe-Thr-Ser-X-Ser-Lys-Gln-Met-Glu-Glu-Glu-Ala-Val-
Arg-Leu-Phe-Ile-Glu-Trp-Leu-Lye-Asn-Gly-Gly-Pro-Ser-Ser-Gly-Ala-Pro-Pro-
Ser-Lys-Lys-Lys-Lys-Lys-Lys-NH2
肽合成以肽合成器Bio536(CSBio)进行。作为原料,使用N-末端的Fmoc保护的(20-44)-AVE0010树脂。原料通过在标准条件下的肽合成制备。
将25.56gFmoc-(20-44)-AVE0010树脂与250mlDMF混合,搅拌5分钟,并且然后溶胀2小时。然后通过剥离漏斗抽吸DMF。溶胀后,Fmoc断开以25%哌啶/DMF进行。
然后,在标准条件下使用具有Fmoc保护的氨基和受保护的侧链如O-叔丁基(OtBu)保护的Glu侧链、三苯甲基(Trt)-保护的Gln侧链、丁基氧基羰基(Boc)-保护的Lys侧链和叔丁基(tBu)-保护的Ser侧链的氨基酸衍生物将氨基酸Val(19)至Leu(10)偶联至原料。
然后,Fmoc-Asp-OH构造块(没有侧链保护基)在有利于形成天冬酰亚胺基团的条件下偶联。
将4.26gFmoc-Asp-OH、1.9gHOBT水合物和2mLDIC在250mLDMF中与树脂混合。将反应混合物搅拌过夜。然后将偶联溶液泵出,并且将树脂以DMF洗涤两次。然后,将3当量的HOBT和3当量的DIC在DMF中与树脂混合。将树脂搅拌过周末。
为了确定天冬酰亚胺形成的程度,将树脂样品以称为King’s混合物的断开混合物处理(D.S.King,C.G.Fields,G.B.Fields,Int.J.PeptideProteinRes.36,1990,255-266),从而将含天冬酰亚胺的肽从树脂释放出来。通过质谱方法测量,发现偶联产物主要以环状天冬酰亚胺的形式存在。
接着,使用2%的DBU在DMF中的溶液用于Fmoc断开。
最后,氨基酸Ser(8)至Gly(1)在标准条件下(除了Emoc保护基不是被哌啶而是被DBU断开)偶联,从而防止环状天冬酰亚胺基团的打开。结果是在树脂上得到了30.5g[Asp(9)-H2O]-AVE0010。
将肽与树脂以及侧链保护基的断开以King’s混合物进行。在固相合成后,从30.5gFmoc保护的树脂得到9.25g原产物(纯度为23.4%,由UV在215nm测量)。
肽与树脂的断开在标准条件(Kingetal.,1990,Supra)下进行。总计而言,在真空干燥后得到9.25g的粗[Asp(9)-H20]-AVE0010。
2.色谱纯化[Asp(9)-H2O]-AVE0010
纯化通过两个RP-HPLC步骤以及随后的冷冻干燥来进行。RP-HPLC步骤使用VarianPrepStar装置进行。填充有C18反相材料(例如用于第一步的DaisogelC18或用于第二步的HydrospherC18)的不锈钢柱用作为固定相。H2O+0.1%三氟乙酸用作流动相A且乙腈用作流动相B。梯度分别在0-80%流动相B(Daisogel)和0-35%流动相B(Hydrospher)下进行。
结果为获得540mg[Asp(9)-H2O]-AVE0010,纯度为91.50%(面积%,由HPLC测量)。纯化产物的分析色谱图示于图3中。
3.分析表征
纯化产物使用质谱表征。纯化的AVE0010用作参比标准物。
该分析表征显示了正确产物[Asp(9)-H20]-AVE0010,其具有的分子量(M+H)+=4838.460,并且AVE0010标准为显示分子量4856.544。[Asp(9)-H2O]-AVE0010与AVE0010的质量差为18.084,相当于H2O分子。[Asp(9)-H2O]-AVE0010的理论单一同位素分子量为4837.534。
