Anthracene-Bridged Photosensitizers for Effective and Safe Photodynamic Therapy
, 2023 Photodynamic therapy (PDT) is a minimally invasive therapeutic modality. However, the residual photosensitizers (PSs) after PDT can still produce toxic singlet oxygen (1O2) under sunlight to damage normal tissues.

Synthesis of New Cytotoxic Aminoanthraquinone Derivatives via Nucleophilic Substitution Reactions
Molecules, 2013 Aminoanthraquinones were successfully synthesized via two reaction steps. 1,4-Dihydroxyanthraquinone (1) was first subjected to methylation, reduction and acylation to give an excellent yield of anthracene-1,4-dione (3), 1,4-dimethoxyanthracene-9,10 ...
