A Ruthenium(II)-Copper(II) Dyad for the Photocatalytic Oxygenation of Organic Substrates Mediated by Dioxygen Activation.

Angewandte Chemie (International ed. in English)

Iali W, Lanoe PH, Torelli S, Jouvenot D, Loiseau F, Lebrun C, Hamelin O, Ménage S.
PMID: 26013299
Angew Chem Int Ed Engl. 2015 Jul 13;54(29):8415-9. doi: 10.1002/anie.201501180. Epub 2015 May 27.

Dioxygen activation by copper complexes is a valuable method to achieve oxidation reactions for sustainable chemistry. The development of a catalytic system requires regeneration of the Cu(I) active redox state from Cu(II). This is usually achieved using extra reducers...

Cunningham BR, Coleman RM, Schaefer AM, Hamelin EI, Johnson RC.
PMID: 33515246
J Anal Toxicol. 2021 Jan 30; doi: 10.1093/jat/bkab010. Epub 2021 Jan 30.

Florida red tides have become more common and persistent in and around the Gulf of Mexico. When in bloom, red tides can produce brevetoxins in high concentrations, leading to human exposures primarily through contaminated food and ocean spray. The...

Design of specific inhibitors of quinolinate synthase based on [4Fe-4S] cluster coordination.

Chemical communications (Cambridge, England)

Saez Cabodevilla J, Volbeda A, Hamelin O, Latour JM, Gigarel O, Clémancey M, Darnault C, Reichmann D, Amara P, Fontecilla-Camps JC, Ollagnier de Choudens S.

Quinolinate synthase (NadA) is a [4Fe-4S] cluster-containing enzyme involved in the formation of quinolinic acid, the precursor of the essential NAD coenzyme. Here, we report the synthesis and activity of derivatives of the first inhibitor of NadA. Using multidisciplinary...

Prolonged Consumption of Sweetened Beverages Lastingly Deteriorates Cognitive Functions and Reward Processing in Mice.

Cerebral cortex (New York, N.Y. : 1991)

Hamelin H, Poizat G, Florian C, Kursa MB, Pittaras E, Callebert J, Rampon C, Taouis M, Hamed A, Granon S.
PMID: 34491298
Cereb Cortex. 2021 Sep 07; doi: 10.1093/cercor/bhab274. Epub 2021 Sep 07.

We investigated the detrimental effects of chronic consumption of sweet or sweetened beverages in mice. We report that consumption of beverages containing small amounts of sucrose during several weeks impaired reward systems. This is evidenced by robust changes in...
