Syntheses and biological activities of fluorescent-labeled analogs of acylpolyamine toxin NPTX-594 isolated from the venom of Madagascar Joro spider
摘要:
Acylpolyamine-type spider toxins are known to be potent and specific blockers against glutamate receptors (GluRs). The present study describes the syntheses and biological activities of several fluorescent-labeled analogs related to a Madagascar Joro spider toxin NPTX-594 to analyze visually the unknown interaction between spider toxins and GluRs.

ABSTRACT A major problem in the use of spermidine for the synthesis of biologically interesting compounds is the selective orthogonal protection of the three different amino groups. Our approach is based on the Fukuyama reaction, starting from putrescine and 3-amino-1-propanol and affording N 8-benzyloxycarbonyl-N 1-tert-butyloxycarbonyl-N 4-(2-nitrobenzenesulfonyl)spermidine (5) in 5 steps in high
摘要 使用亚精胺合成具有生物学意义的化合物的一个主要问题是三个不同氨基的选择性正交保护。我们的方法基于福山反应,从腐胺和 3-氨基-1-丙醇开始,分 5 个步骤提供 N 8-苄氧羰基-N 1-叔丁氧羰基-N 4-(2-硝基苯磺酰基)亚精胺 (5)高产。
