kinds of metal ions [magnesium(II) or zinc (II)] in the phthalocyanine core and the effects of the introduction of (3,4-dimethoxyphenyl)-3-oxoprop-1-en-1-yl)phenoxy units at both peripheral and non-peripheral positions of the phthalocyanine skeleton on photophysical and photochemical properties of the new substituted magnesium(II) and zinc(II) phthalocyanines have also been examined in DMF. The obtained
设计并合成了含有新的外围和非外围四取代的无金属和金属酞菁衍生物的查尔酮(方案1,方案2)。查尔酮-酞菁的结构通过常见的光谱技术进行了表征,例如LC–MS / MS(对于新的酞菁衍生物3a),基态电子吸收光谱(对于所有新的酞菁),1 H NMR光谱(对于所有新的化合物),13 C NMR光谱法(用于新型邻苯二甲腈和不含金属的酞菁衍生物),傅立叶变换红外光谱(FT - IR,带有ATR采样附件)(对于所有新化合物)和MALDI-TOF质谱数据(对于所有新型酞菁和新邻苯二甲腈衍生物3b)以及元素分析。另外,酞菁核中存在不同种类的金属离子[镁(II)或锌(II)]的影响以及引入(3,4-二甲氧基苯基)-3-氧代丙-1-的影响还已在DMF中检查了酞菁骨架的周边和非周边位置的烯-1-基)苯氧基单元对新型取代镁(II)和锌(II)酞菁的光物理和光化学性质的影响。将获得的结果与未取代的酞菁镁(II)和锌(

A series of chalcone Mannichbasederivatives were designed, synthesized and evaluated as multifunctional agents for the treatment of Alzheimer’s disease based on the multi-target directed ligands design strategy. In vitro assays demonstrated that most of the derivatives exerted potent selective inhibitory potency on AChE with good multifunctional properties. Among them, representative compound 7c
