Two novel NO photodonors (NOPDs) based on BODIPY and Rhodamineantennae activatable with the highly biocompatible green light are reported. Both NOPDs exhibit considerable fluorescence emission and release NO with remarkable quantum efficiencies. The combination of the photoreleasing and emissive performance for both compounds is superior to those exhibited by other NOPDs based on similar light-harvesting
A few compounds in which the nitric oxide (NO) photodonor N‐[4‐nitro‐3‐(trifluoromethyl)phenyl]propane‐1,3‐diamine is joined to the mitochondria‐targeting alkyltriphenylphosphonium moiety via flexible spacers of variable length were synthesized. The lipophilicity of the products was evaluated by measuring their partition coefficients in n‐octanol/water. The obtained values, markedly lower than those

A multifunctional nanoplatform with four-in-one photoresponsive functionalities has been achieved through the co-encapsulation of two chromo-fluorogenic components within biocompatible polymeric nanoparticles. This engineered nanoconstruct efficiently delivers different photosensitizers in melanoma cells, which can be detected through their dual-color fluorescence, and induces amplified cell mortality due to the simultaneous photogeneration of singlet oxygen and nitric oxide.
