Herein, we report dipropylamine (DPA) as a fluorenylmethyloxycarbonyl (Fmoc) deprotection reagent to strongly reduce aspartimide formation compared to piperidine (PPR) in high-temperature (60 °C) solid-phase peptide synthesis (SPPS). In contrast to PPR, DPA is readily available, inexpensive, low toxicity, and nonstench. DPA also provides good yields in SPPS of non-aspartimide-prone peptides and peptide dendrimers.
在此,我们报道二丙胺(DPA)作为一种芴甲氧羰基(Fmoc)脱保护试剂,在高温(60°C)固相肽合成(SPPS)中,与哌啶(PPR)相比,能显著减少天冬酰胺的形成。与PPR不同,DPA容易获得、价格低廉、毒性低且无异味。在不易形成天冬酰胺的肽和肽树枝状大分子的SPPS中,DPA也能提供良好的产率。
