Photoreactions of quinones with alkynes under catalytic and non-catalytic conditions were studied. Contrary to recent reports, simple irradiation blue light is sufficient trigger the [2+2] photocycloadditions, which afford...

Running across Enron Field during the Owls' baseball game on Friday seemed like a ha rmless prank to Jose De La Pena. But it laiided the Baker College senior in jail for the night, and he may face fines of up to $2,500. At the game, a group of about 25 Baker students, including De \ x Pena, along with Baker Master Mickey Quinones were sitting on the third base line. Quinones had purchased ticke...

The transcriptional regulator QsrR is converted into a genetically encoded fluorescent probe capable of ratiometric monitoring of quinones in living cells with high sensitivity and selectivity.

A series of highly functionalized quinones was prepared by an original reaction of 2,3-bis(chloromethyl)-1,4-dimethoxyanthraquinone (6) with various nitronate anions under electron transfer reaction conditions.

A straightforward and efficient method for the palladium-catalyzed direct cross-coupling of chromones with various quinones has been developed to rapidly construct isoflavone quinone structural motifs.

In this study we demonstrate for the first time that GSH could rapidly conjugate with dopamine (DA)-derived DA-o-quinones without enzymatic catalysis to form short-lived intermediate GSHconjugates (2-S-GSH-DA-o-quinone and 5-S-GSH-DA-o-quinone). These intermediate GSHconjugates are unstable and would finally form reactive or non-reactive GSH-conjugates dependent on ambient reductive forces. Und...
