synthesized from methyl pheophorbide a and its carboxyl derivatives by reactions with aminomethyl derivatives of 2,4-dimethylphenol, 2-isocamphyl-4- methylphenol, 2-bornyl-4-methylphenol, and 2-isobornyl-4-methylphenol. The antioxidant activity of some conjugates was established by investigation of their ability to inhibit the accumulation of secondary products of lipid peroxidation in a brain of laboratory
通过与 2,4-二甲基苯酚、2-isocamphyl-4-甲基苯酚、2-冰片基-4-甲基苯酚和 2-异冰片基-4-甲基苯酚的氨基甲基衍生物反应,由甲基脱镁叶绿素 a 及其羧基衍生物合成了新的酰胺偶联物. 一些偶联物的抗氧化活性是通过研究它们在体外抑制实验室小鼠脑中脂质过氧化次级产物积累的能力来确定的。已经在 SH-SY5Y 细胞(神经母细胞瘤)中 H2O2 诱导的氧化应激模型上研究了卟啉和萜烯酚缀合物的神经保护特性。

Reactions of bis(dialkylamino)methanes and ethoxydialkylaminomethanes with nucleophilic aromatic heterocycles in the presence of sulfur dioxide result in the formation of the expected Mannich bases in good yields. Reactions of phenols are similarly activated by sulfur dioxide which lead to improved regioselectivity: in particular the reactions of 2,5-dimethylphenol result in the formation of 2-dialkylaminomethyl-3,6-dimethylphenol whereas reaction occurs at the 4-position using the classical procedures.
