Модификация природных диоксиантрахинонов кислотами
20 March 2018 Лариса Николаевна Гребцова Омарова А.С., Музычкина Р.А., Корулькин Д.Ю.
Аннотация. Так как оксипроизводные антрахинонов являются активным началом многих промышленно значимых красителей, индикаторов, рострегуляторов, гербицидов и лекарственных препаратов, получение их производных представляет научный и практический интерес. В работе рассмотрены направления модификации природных диоксиантрахинонов путем взаимодействия их с кислотами, а именно с серной, азотной и фосфорной по двум направлениям – электрофильное замещение и этерификация гидроксигрупп. В большей степени описано получение только β-сернокислого эфира ализарина, эфиры на основе фосфорной и азотной кислот не исследованы. Рассмотрены условия сульфирования, нитрования и фосфорилирования диоксиантрахинонов различными агентами и биологическая активность продуктов реакций. Установлено, что модификация структур природных диоксиантрахинонов кислотами является научно-обоснованным подходом при разработке новых эффективных препаратов, биологически доступных для организма, которые обладают широким спектром активностей.
Ключевые слова: диоксиантрахиноны, сульфирование, нитрование, фосфорилирование, ализарин, хинизарин, хризофанол, фисцион, производные антрахинонов
