A novel spider toxin, NPTX-594, comprised of four constituents: i.e., 2,4-dihydroxyphenylacetic acid (Dhpa), asparagine, 4,8-diaza-1,12-dodecanediamine (Dada), and lysine, was chemically synthesized. The synthetic compound was completely identical with the natural product as regards 1H NMR and mass spectra. The structure of NPTX-594 was thus determined synthetically to be N12-(Dhpa-Asn)-N1-Lys-Dada
化学合成了一种新型蜘蛛毒素 NPTX-594,它由四种成分组成:即 2,4-二羟基苯乙酸 (Dhpa)、天冬酰胺、4,8-二氮杂-1,12-十二烷二胺 (Dada) 和赖氨酸。合成化合物的 1H NMR 和质谱与天然产物完全相同。NPTX-594 的结构因此综合确定为 N12-(Dhpa-Asn)-N1-Lys-Dada,如光谱分析所建议的。
