Quenching of Singlet Molecular Oxygen, O2(1Δg), by Dipyridamole and Derivatives

Dipyridamole (DIP) is known for its vasodilating and antiplatelet activity, exhibiting also a potent antioxidant effect, strongly inhibiting lipid peroxidation. This effect has been studied in

The role of carotenoids in the prevention of human pathologies.

Impact of LDL carotenoid and alpha-tocopherol content on LDL oxidation by endothelial cells in culture.

The specific content of carotenoids in low density lipoprotein (LDL) clearly modulates its susceptibility to oxidation, but individual carotanoids may either inhibit or promote LDL oxidation.

Oxygen and hydrogen peroxide enhance light‐induced carotenoid synthesis in Neurospora crassa

Effect of carotenoid oxidation products on neutrophil viability and function

The prooxidant and proapoptotic activities of carotenoid oxidation products could account, at least in some cases, for the procancerogenic properties of carOTenoid rich diet.

KINETIC AND SPECTROSCOPIC FEATURES OF SOME CAROTENOID TRIPLET STATES: SENSITIZATION BY SINGLET OXYGEN

Abstract— Triplet‐triplet absorption spectra of a series of carotenoid pigments in benzene solution have been determined by pulse radiolysis experiments. The natural lifetimes in deaerated solution

Electronic Energy Transfer from Sinclet Molecular Oxygen to Carotenoids

Abstract Aerated benzene solutions containing anthracene together with one of the carotenoids, β-carotene, β-apo-8′-carotenal, ethyl β-apo-8′-carotenate and canthaxanthin were subjected to laser

Lycopene as the most efficient biological carotenoid singlet oxygen quencher.

ON THE MECHANISM OF QUENCHING OF SINGLET OXYGEN IN SOLUTION

Laser photolysis experiments of aerated solutions, in which triplet anthracene is produced and quenched by oxygen, yielding singlet oxygen which then sensitizes absorption due to triplet carotene, firmly establishes diffusion‐controlled energy transfer from singletoxy as the quenching mechanism in the case of β‐carotene.

CAROTENOID CHROMOPHORE LENGTH AND PROTECTION AGAINST PHOTOSENSITIZATION

It was found that the broad EPR signal, induced by light in benzene solutions of chlorophyll a and hydroquinone, and related to chlorophyLL oxidation, is efficiently quenched by P‐438 and to a much smaller extent also by Sarcina phytoene.
