| 1 | Molecular Structural Evolution of Near-Infrared Cationic AggregationInduced Emission Luminogens:Preclinical Antimicrobial Pathogens Activities and Tissues Regeneration显示文摘Increasingly infectious diseases from microbial pathogens(including bacteria and fungi)threaten human health:a situation that has aroused public health concern around the world.Unfortunately,broad-spectrum antimicrobial agents for treatment resistance pathogens and molecular research on their antimicrobial mechanisms are still scarce.Thus,the development of smart agents against microbial infection for surmounting the above dilemmas is an urgent task.In this contribution,we have tactfully designed a family of flexible aggregation-induced emission luminogens(AIEgens)with various alkyl chain lengths and successfully optimized a cationic AIEgen TPA-S-C6-NMe_(3)^(+)based on the molecular relay strategy for killing both bacteria and fungi in vitro with desired results under white light irradiation,superior to traditional commercial photosensitizers including methylene blue,chlorin e6,and protoporphyrin IX.The cationic AIEgen TPA-S-C6-NMe_(3)^(+)was bound to microbial pathogens via electrostatic and hydrophobic forces and exerted antimicrobial efficacy due to the synergistic effect of alkyl chain length,reactive oxygen species(ROS)generation capability,and two positive charges.Remarkably,AIEgen TPA-S-C6-NMe_(3)^(+)also exhibited a striking antimicrobial activity in vivo,and promoted the generation of new blood vessels and fibroblasts in bacteria-infected tissues,which was beneficial for wound healing in mice.Overall,we expect that our work could provide a powerful tool against microbial pathogens to avoid infections and to promote tissues regeneration in clinical practice. | Haidong Li Liuwei Zhang Jingjing Han Dayeh Kim Heejeong Kim Jeongsun Ha Jingyun Wang Juyoung Yoon | 2022 | CCS Chemistry2022，4，2： | 0 |
