Synthetic approaches to gabapentin bioconjugates that overcome the tendency of gabapentin to cyclize into its γ-lactam are studied. Gabapentin was converted by N-acylation at its N-terminus into di-, tri-, and tetrapeptides (l-Ala-Gbp, l-Val-Gbp, l-Ala-l-Phe-Gbp, Gly-l-Ala-β-Ala-Gbp). Carboxyl-activated Boc-protected gabapentin was used to N-, O-, and S-acylate small peptides and hormones to give conjugates
研究了克服加巴喷丁环化成其γ-内酰胺的趋势的加巴喷丁生物缀合物的合成方法。加巴喷丁被转化通过在它的N-末端N-酰化成二,三,四肽和(升-Ala-英镑,升-Val-英镑,升-Ala-升-Phe-英镑,Gly-升-Ala- β-Ala-Gbp)。羧基活化的Boc保护的加巴喷丁用于N-,O-和S-酰化小肽和激素,以提供结合物,这些结合物也可提供含有受构象限制的加巴喷丁单元的前药。
