A simple and specific divalent vancomycin-porphyrin has been developed. This divalent vancomycin-porphyrin conjugate indicates promising properties in fluorescent imaging and photodynamic inactivation of vancomycin-sensitive and vancomycin-resistant enterococci (VRE) bacterial strains.

The combined effects of biofilm dispersion with a 2-aminoimidazole-triazole conjugate and bactericidal activity with a photodynamic inactivation agent suggest a novel combination therapy for treating diverse microbial infections.

The impact of substituents on the photochemical and biological properties of tetraphenylporphyrin-based photosensitizers for photodynamic therapy of cancer (PDT) as well as photodynamic inactivation of microorganisms (PDI) was examined. Spectroscopic and physicochemical properties were related with therapeutic efficacy in PDT of cancer and PDI of microbial cells in vitro. Less polar halogenated...

Aim: To evaluate the capacity of hematoporphyrin monomethyl ether 23 (HMME) in the presence of light to cause photodynamic inactivation (PDI) of C. 24 albicans. Materials & methods: HMME photoactivity was evaluated against 25 azole-susceptible and resistant C. albicans. The mechanisms by which PDI of C. 26 albicans occurred were also investigated. Results: HMME-mediated PACT caused a 27 dose-de...

Multimodal therapy has been recognized as a powerful platform for the precise treatment of cancer. However, reported multimodal therapeutic systems often involve sophisticated components and tedious fabrication procedures. As such, developing nature-inspired easily-obtainable theranostic agents cancer remains challenging. In this work, we propose nanothylakoids agent both in vitro vivo. Nanothy...

The rates of virus inactivation by 4-nitroquinoline 1-oxide (NQO) and 4-hydroxyaminoquinoline 1-oxide (HAQO) were compared and samples of cytomegalovirus (CMV)-infected cell lysates to which NQO had been added were examined for the presence of HAQO. These experiments demonstrated that (i) CMV inactivation by HAQO was more rapid than with NQO, (ii) virus inactivation by either NQO or HAQO failed...
