合成了一组新型含羧酸-1,8-萘酰亚胺基的单偶氮分散染料。所有中间体和染料均采用重结晶和柱层析法纯化。纯化产物通过 1 H NMR、13 C NMR、FTIR、DSC、UV-VIS和元素分析进行表征。对合成染料在不同溶剂中的分光光度法进行了研究,以获得它们的最大吸收、摩尔消光系数和溶剂致变色效应。合成染料在丙酮中的最大吸收峰为(513-549 nm),摩尔消光系数为(17405-38939 1/mol cm)。通过将介质从氯仿改为 DMF,所有染料的溶剂致变色效应都增加了。在含有分散剂的水中制备合成染料的分散液并应用于涤纶织物。染色织物表明,所有合成染料都适用于涤纶纤维的染色,产生深红色至蓝红色,牢度非常好。

The present invention relates to compositions which inhibit the binding of nerve growth factor to the p75NTR common neurotrophin receptor and methods of use thereof. In one embodiment, the compound which inhibits binding of nerve growth factor to p75NTR comprises, particularly when bound to nerve growth factor, at least two of the following: (1) a first electronegative atom or functional group positioned to interact with Lys34 of nerve growth factor; (2) a second electronegative atom or functional group positioned to interact with Lys95 of nerve growth factor; (3) a third electronegative atom or functional group positioned to interact with Lys88 of nerve growth factor; (4) a fourth electronegative atom or functional group positioned to interact with Lys32 of nerve growth factor; and (5) a hydrophobic moiety which interacts with the hydrophobic region formed by Ile31, Phe101 and Phe86 of nerve growth factor.

Abstractmagnified imageThe synthesis and characterisation of a series of novel 4‐acylamino and 4‐alkylamino‐N‐1,8‐naphthalimides is described. The UV‐visible absorption and emission properties of the compounds are reported. Significant solvent effects are noted for 4‐n‐butyl‐9‐n‐butyl‐1,8‐naphthylimide. The incorporation of acetyl and chloroacetyl groups into the 4‐substituent markedly increases the fluorescence quantum yield compared with 4‐alkylamino substituemnts.
