Antibacterial hydrophilic compound and use thereof

The present disclosure provides an antibacterial hydrophilic compound. The antibacterial hydrophilic compound may react, induced by light through a hydrogen abstraction group in the structural formula thereof, with a C—H group and thus bind to a surface of a material having the C—H group (for example, chemical fibers such as polyester, chinlon, and the like; plastics, rubbers, and other similar materials), which can impart a durable antibacterial activity and hydrophilicity to the material. The antibacterial hydrophilic compound has a relatively strong binding force to the surface of the material without damaging the mechanical properties of the raw material. The present disclosure also provides a modified material that is modified by the antibacterial hydrophilic compound.

CATIONIC ANTIMICROBIAL OLIGO-GUANIDINIUM DENDRIMERS AND COMPOSITIONS
20220362176 · 2022-11-17 ·

A new synthesized non-peptide cationic oligo-guanidinium dendrimers containing a number of positive charges, 6, 9, 12, and 18 for use as antimicrobial agents and a method for synthesizing non-peptide cationic oligo-guanidinium dendrimers G12 and G18. These designed and synthesized dendrimers exhibit antimicrobial activities as well as biofilm disrupting activity against various pathogens such as Gram-negative bacteria, Gram-positive bacteria, and fungi. The application of these dendrimers are very broad, which includes application to pharmaceutical compounds that are covalently or non-covalently complexed. These combinations are important in helping the body reach the proper immune balance required for maximized function and/or optimal health.
