  • Patent number: 11807529
    Abstract: The invention proposes the photosensitized generation of nitric oxide (NO) from alanosine (3-(hydroxynitrosoamino)-D,L-alanine) by aluminum phthalocyanine tetrasulfonate (AlPcS4). While NO is obtained in nitrogen-saturated solutions, the invention proposes that both NO and peroxynitrite are produced in air-saturated solutions. Enhancement of NO production occurs in the presence of ubiquinone-0. The invention evidence that NO is produced by the photosensitized oxidation of alanosine. Both NO and peroxynitrite are detected during photoirradiation of AlPcS4 in the presence of 2-methyl-2-nitrosopropane (MNP) and hypoxanthine, but not in the absence of hypoxanthine, in air-saturated solutions, where HX is acting as sacrificial electron donor, thus promoting superoxide formation.
