An efficient one-pot chemical synthesis of snake venom toxin Mambalgin-1 was achieved using an azide-switch strategy combined with hydrazide-based native chemical ligation. Synthetic Mambalgin-1 exhibited a well-defined structure after sequential folding in vitro. NMR spectroscopy revealed a three-finger toxin family structure, and the synthetic toxin inhibited human acid-sensing ion channel 1a.
通过将叠氮开关策略与基于酰肼的天然化学连接相结合，实现了蛇毒毒素曼巴精-1的高效一锅法化学合成。合成的曼巴精-1在体外顺序折叠后呈现出明确的结构。核磁共振光谱揭示了一种三指毒素家族结构，并且合成毒素抑制了人类酸敏感离子通道1a。
