Abstract
A novel pheophorbide derivative, trimethyl-152-[L-aspartyl]pheophorbide a was synthesised and investigated for anti-tumor activity. The prepared photosensitizer had good absorption in the phototherapeutic window and high ROS yields. It exhibited excellent phototoxicity higher than reference compound m-THPC when irradiated by 650 nm light in vitro, and obvious photodynamic anti-tumor effect in vivo. It causes cellular apoptosis or necrosis under laser irradiation and localizes in mitochondria, lysosome, and endoplasmic reticulum. The observed high efficacy was rationalized by efficient introduction into the blood by facile transfer through membranes, which is supported by molecular dynamics simulation studies. This work provides a new candidate photosensitizer for anti-cancer treatment.
期刊介绍:
Quality research. Outstanding publications. With an impact factor of 3.124 (2019), ChemMedChem is a top journal for research at the interface of chemistry, biology and medicine. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies.
ChemMedChem publishes primary as well as critical secondary and tertiary information from authors across and for the world. Its mission is to integrate the wide and flourishing field of medicinal and pharmaceutical sciences, ranging from drug design and discovery to drug development and delivery, from molecular modeling to combinatorial chemistry, from target validation to lead generation and ADMET studies. ChemMedChem typically covers topics on small molecules, therapeutic macromolecules, peptides, peptidomimetics, and aptamers, protein-drug conjugates, nucleic acid therapies, and beginning 2017, nanomedicine, particularly 1) targeted nanodelivery, 2) theranostic nanoparticles, and 3) nanodrugs.
