A series of new C-4-derivatives of α-mangostin has been synthesized with the use of Mannich reaction and alkylation with 4-bromomethyl-2,6-dialkylphenols. It has been shown on a model of H2O2-induced erythrocyte hemolysis that the Mannich bases containing morpholinomethyl and piperidinomethyl fragments differ from parent α-mangostin by their high antioxidant and membrane-protective activity.
利用曼尼希反应和与4-溴甲基-2,6-二烷基苯酚的烷基化反应,已经合成了一系列新的α-mangostinC-4衍生物。在H 2 O 2诱导的红细胞溶血模型中已经表明,含有吗啉代甲基和哌啶子基甲基片段的曼尼希碱基与母体α-芒果素的区别在于它们的高抗氧化剂和膜保护活性。
