PorGal8, a porphyrin conjugated with dendritic galactose units, binds to galectin-1 in bladder cancer cells and induces localized cell death after light activation. Although it has been previously shown that photodynamic treatment (PDT) affects the c

Novel triazole-porphyrin derivatives (TZ-PORs) were synthesized through the Heck reaction and then incorporated into polyvinylpyrrolidone (PVP) micelles. After verifying that this incorporation did not compromise the photophysical and chemical featur

Both the 3-amino-2H,4H-1,2,4-triazolium cation and the pyrazine-2-carboxylate anion in the title salt, C2H5N4+·C5H3N2O2−, were formed by an unexpected decarboxylation reaction, from 5-amino-1H-1,2,4-triazole-3-carboxylic acid and pyrazine-2,3-dica
