Sustainable and efficient manufacturing methods for N-methylated peptides remain underexplored despite growing interest in therapeutic N-methylated peptides within the pharmaceutical industry. A methodology for the coupling of C-terminally unprotected N-methylamino acids mediated by an isostearic acid halide (ISTAX) and silylating reagent has been developed. This approach allows for the coupling of
尽管制药行业对治疗性N-甲基化肽的兴趣日益浓厚,但N-甲基化肽的可持续和高效制造方法仍未得到充分探索。已经开发了一种由异硬脂酰卤 (ISTAX) 和甲硅烷基化试剂介导的C-末端未保护N-甲基氨基酸的偶联方法。这种方法允许在温和条件下以高产率偶联多种氨基酸和肽,而无需在C的过程中进行C端脱保护步骤-末端伸长。这些优点使其成为生产含有N-甲基氨基酸的肽治疗剂和诊断剂的有用合成方法。
