Galstyan, Anzhela published the artcileExploring the Impact of Coordination-Driven Self Assembly on the Antibacterial Activity of Low-Symmetry Phthalocyanines, COA of Formula: C8H4N2, the main research area is phthalocyanine coordination driven self assembly antimicrobial photodynamic therapy; antimicrobial photodynamic therapy; bacterial biofilm; pH-responsiveness; phthalocyanine; self-assembly.

Understanding the action mechanisms of self-assembled photosensitizers is very important to determine the requirements that constructing monomers should fulfill to obtain nanostructures with the desired function. Here, the synthesis, supramol. aggregation tendency, photophys. properties and antimicrobial photodynamic activity of low symmetry metal-free phthalocyanine is carefully examined and compared with its metalated counterpart. When exposed to the media with different pH values striking differences in the self-assembly of these two derivatives were observed Equilibrium between active and inactive forms of this unique supramol. system were shifted upon change of the microenvironment influencing its biol. activity against Gram-pos. and Gram-neg. bacteria in planktonic and biofilm state. DFT calculations helped to explain possible differences in the aggregate formation, showing that metal-ligand interaction is a key process behind the higher activity of metalated derivative These results point out the importance of intermol. interactions between photosensitizers, which is essential to guide the design of self-assembled phototheranostic agents with improved performance.
