Halogenated phenotiazine as photoantimicrobial agent against Staphylococcus aureus. Evaluation of the vehiculization in polymeric nanoparticles
(Elsevier, 2019-11)
A thiazine derivative of AzB, the monoiodinated Azure B (AzBI), was designed, characterized, chemical and photochemically evaluated, and screened for antibacterial activity. The monoiodinated derivative showed better ...
Thionine in the design of new photosensitizers: Bromination and vehiculization in polymeric nanoparticles
(Elsevier Science, 2020-07-15)
To face the challenges of optimizing the properties of the photosensitizers currently used in the photodynamic inactivation of various microorganisms, we propose the bromination of thionine and the use of polymeric ...
Biopolymer nanoparticles for vehiculization and photochemical stability preservation of retinol
(Elsevier, 2017-09)
This paper gives experimental information about the production of biopolymer nanoparticles (BNPs) for vehiculization and photochemical preservation of retinol (RET). BNPs production involved the combination of two biopolymer ...
Phospholipid multilamellar vesicles entrapping phenothiazine photosensitizers. Preparation, characterization and evaluation of their photodynamic properties
(Elsevier Science, 2019-01)
The aim of the present paper was to optimize the properties of phenothiazine photosensitizers (PSs), Azure B and its monobrominated derivative. They were entrapped in multilamellar liposomes of egg phosphatidylcholine (EPC) ...
Two phenothiazine dyes as photosensitizers for the production of singlet oxygen. Photophysics, photochemistry and effects of aggregation
(Elsevier Science, 2019-04)
The aim of this work was to investigate the aggregation effect of Azure B and monobrominated Azure B on their singlet oxygen generation. The monomeric and dimeric forms of these dyes were evaluated to select the species ...
