  摘要：

  为了确认从蜘蛛（Nephila clavata）毒液中鉴定出的spidamine和joramine的结构，我们收敛性地合成了这两种化合物，它们具有共同的侧链N-(L-天冬酰胺基)-N'-(3-氨基丙基-β-丙氨酸)-1, 5-戊二胺。通过以n-丙醇胺为起始材料合成了共同侧链的合成单元，该物质被转化为7-叠氮-N-苄氧羧酸-4-氮杂庚酸N-羟基琥珀酰亚胺酯。这个酯与tert-丁氧羧基-L-天冬酰胺-1, 5-戊二胺偶联，得到共同侧链的合成单元。在spidamine的最终合成中，共同侧链的合成单元与由Willgerodt-Kindler反应2, 4-二羟基乙酰苯酮得到的2, 4-二苄氧基苯乙酸N-羟基琥珀酰亚胺酯反应。保护型的spidamine经过催化氢化以去除保护基团，最终得到了spidamine，其产率为从n-丙醇胺起始物的13%。在joramine的最终合成中，共同侧链的合成单元与4-苄氧基苯乙酸N-羟基琥珀酰亚胺酯反应。保护型的joramine同样经过催化氢化以生成joramine，本体的产率为11%。通过1H-NMR和13C-NMR分析了这两种合成化合物的构象。利用实验室神经肌肉突触考察了它们对谷氨酸受体的阻断活性。

  摘要：

  An efficient and versatile synthesis of acylpolyamine spider toxins was developed based on the structural classification of the Nephila and Nephilengys spider toxins using the 2-nitrobenzenesulfonamide protecting group. The naturally occurring toxins 1-5 representing each structural type have been efficiently synthesized by this method in a high overall yield with few steps. (C) 2002 Elsevier Science Ltd.

  In order to study the structure-activity relationships of spidamine and joramine found in the venom of Joro spider, Nephila clavata, we attempted to synthesize various analogs. Six analogs were convergently synthesized according to our previous method for the synthesis of spidamine, N-(3-aminopropyl-β-alanyl)-N'-(2, 4-dihydroxy-phenylacetyl-L-asparaginyl)-1, 5-pentanediamine and joramine, N-(3-aminopropyl-β-alanyl)-N'-(4-hydroxyphenyl-acetyl-L-asparaginyl)-1, 5-pentanediamine. The biological activities of the analogs and four intermediates were compared with those of synthetic spidamine and joramine in three bioassay systems, lobster neuromuscular synapse, cockroaches and mosquito larvae. The glutamate receptors in these systems were inhibited by some analogs, and the D-asparagine- or indoleacetyl-containing analogs were found to be strong inhibitors. These compounds have potential application as insecticides.

  为了研究在Joro蜘蛛（Nephila clavata）毒液中发现的spidamine和joramine的结构-活性关系，我们尝试合成各种类似物。根据我们之前合成spidamine的的方法，我们共合成了六种类似物，分别是N-(3-氨基丙基-β-丙氨酸)-N'-(2, 4-二羟基苯乙酰-L-天冬氨酰)-1, 5-戊二胺和joramine，N-(3-氨基丙基-β-丙氨酸)-N'-(4-羟基苯乙酰-L-天冬氨酰)-1, 5-戊二胺。这些类似物及四种中间体的生物活性与合成的spidamine和joramine在三种生物测定系统中进行了比较，包括龙虾神经肌肉突触、蟑螂和蚊子幼虫。在这些系统中，某些类似物抑制了谷氨酸受体，而含有D-天冬氨酸或吲哚乙酰的类似物被发现是强抑制剂。这些化合物在农药方面具有潜在应用前景。

  In order to confirm the structures of spidamine and joramine, identified from the venom of a spider (Nephila clavata), we convergently synthesized both compounds, which have a common side chain of N-(L-asparaginyl)-N'-(3-aminopropyl-β-alanyl)-1, 5-pentanediamine. A synthon of the common side chain was synthesized by starting with n-propanolamine which was converted to 7-azido-N-benzyloxycarbonyl-4-azaheptanoic acid N-hydroxysuccinimidyl ester. The ester was coupled with tert-butyloxycarbonyl-L-asparaginyl-1, 5-pentanediamine to give the synthon of the common side chain. In the final synthesis of spidamine, the synthon of the common side chain was reacted with 2, 4-dibenzyloxyphenylacetic acid N-hydroxysuccinimidyl ester, obtained by Willgerodt-Kindler reaction of 2, 4-dihydroxyacetophenone. The protected spidamine was catalytically hydrogenated to remove protective groups, affording spidamine itself in 13% yield from n-propanolamine. In the final synthesis of joramine, the synthon of the common side chain was reacted with 4-benzyloxyphenyl acetic acid N-hydroxysuccinimidyl ester. The protected joramine was also catalytically hydrogenated to produce joramine itself in 11% yield.The conformations of both synthesized compounds were analyzed by 1H-NMR and 13C-NMR. Their blocking activities on glutamate receptors were examined using labster neuromuscular synapses.

  An efficient and versatile synthesis of acylpolyamine spider toxins of all structural types classified by extensive MS analysis has been achieved. By using 2-nitrobenzenesulfonamide as an effective activating and/or protecting group (the Nosyl strategy), the naturally occurring toxins 1-8 corresponding to Types A-F were concisely synthesized in high overall yield.
