Original language name
Tetraphenylporphyrin-cobalt(III) Bis(1.2-dicarbollide) Conjugates: From the Solution Characteristics to Inhibition of HIV Protease
Original language description
Tetraphenylporphyrin conjugates with one (PB1) and four (PB4) cobalt(III)bis(1,2-dicarbollide) substituents were synthesised and the physicochemical and photophysical properties as well as inhibition of HIV-1 protease were described. In methanol, both PB1 and PB4 were monomeric producing the triplet states and singlet oxygen after excitation. The triplet states of PB4 were quickly protonated. Porphyrins exhibited a small decrease of the quantum yields of the singlet oxygen formation (17% for PB4 and 13%for PB1) as compared with 5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrin. On the contrary, no singlet oxygen was detected in aqueous solutions because of strong aggregation. Light scattering and atomic force microscopy (AFM) measurements documented that the behavior of aggregates in aqueous solutions is fairly complex and depends on pH, concentration, and agign.
