Synthesis of the Selective Neuronal Nitric Oxide Synthase (nNOS) Inhibitor 5,6-Dibromo-2′-demethylaplysinopsin
摘要:
本研究首次合成了选择性神经元一氧化氮合酶(nNOS)抑制剂 5,6-二溴-2′-去甲基芹菜苷(5,6-dibromo-2′-demethylaplysinopsin)。稀有的 5,6-二溴吲哚分子是利用以前未使用过的吲哚-3-羧酸二溴化物构建的,其产物通过 X 射线晶体学进行了验证。在分离报告中发现,该天然产物的特征为其三氟乙酸盐。

N-(Triphenylphosphoranylidene)sulfamoyl chloride was reacted with the ethyl ester monohydrobromide of a series of N-alkylcarbamimidothioic acids (alkylpseudothiuronium salts) to give ethyl N-alkyl-N'-[(triphenylphosphoranylidene)amino]sulfonyl}carbamimidothioates which: were converted to the corresponding N-alkyl-N'-[(triphenylphosphoranylide)amino]sulfonyl}thioureas by S-dealkylation with NaHS/H2S in DMF.
