Повышение водорастворимости алкилированных вердазильных радикалов за счет введения фрагментов полиэтиленгликоля

Abstract

Alkylated verdazyl radicals can be considered as new and promising agents for photodynamic therapy. Their main limitation is their extremely low water solubility that is important for further biological investigations. To solve this problem, we decided to functionalize the molecule with polyethylene glycol fragment. In this work, we synthesized two pegylated alkylated verdazyl radicals which have higher water solubility, and proposed two routes for the synthesis of such molecules. The obtained result opens up new perspectives for the development of oxygen-independent photodynamic therapy.
