Kinetic Control in the Regioselective Alkylation of Pterin Sensitizers: A Synthetic, Photochemical, and Theoretical Study
(Wiley Blackwell Publishing, Inc, 2018-09)
Alkylation patterns and excited-state properties of pterins were examined both experimentally and theoretically. 2D NMR spectroscopy was used to characterize the pterin derivatives, revealing undoubtedly that the decyl ...
Lipophilic Decyl Chain-Pterin Conjugates with Sensitizer Properties
(American Chemical Society, 2018-03)
A new series of decyl chain [-(CH2)9CH3] pterin conjugates have been investigated by photochemical and photophysical methods, and with theoretical solubility calculations. To synthesize the pterins, a nucleophilic substitution ...
Immobilization of alkyl-pterin photosensitizer on silicon surfaces through in situ SN2 reaction as suitable approach for photodynamic inactivation of Staphylococcus aureus
(Elsevier Science, 2021-02)
The tuning of surface properties through functionalization is an important field of research with a broad spectrum of applications. Self-assembled monolayers (SAMs) allow the surface tailoring through the adsorption of ...
Mono- and Bis-alkylated lumazine sensitizers: Synthetic, molecular orbital theory, nucleophilic index and photochemical studies
(Wiley Blackwell Publishing, Inc, 2021-01)
Mono- and bis-decylated lumazines have been synthesized and characterized. Namely, mono-decyl chain [1-decylpteridine-2,4(1,3H)-dione] 6a and bis-decyl chain [1,3-didecylpteridine-2,4(1,3H)-dione] 7a conjugates were ...
Alkylation of a hydrophilic photosensitizer enhances the contact-dependent photo-induced oxidation of phospholipid membranes
(Elsevier, 2021-03)
Lipophilic photosensitizers able to photo-induce lipid oxidation in biomembranes are, in general, much more efficient than hydrophilic ones; acting through the formation of singlet oxygen (1O2), which oxidizes the fatty ...
