Mechanism of action of novel naphthofuranquinones on rat liver microsomal peroxidation.

6 Sep 2009 In order to elucidate the effect on mammal systems of new derivatives from 2-hydroxy-3-allyl-naphthoquinone, alpha-iodinated naphthofuranquinone (NPPN-3223), beta-iodinated naphthofuranquinone (NPPN-3222) and beta-methyl naphthofuranquinone ... Read more...

Reactivity of neutral Mo(S2C6H4)3 in aqueous media: an alternative functional model of sulfite oxidase.

5 Sep 2009 The kinetics of the reaction of neutral [Mo(S2C6H4)3] with hydrogen sulfite to produce the anionic Mo(V) complex, [Mo(S2C6H4)3]-, and sulfate have been investigated. It has been shown that [Mo(S2C6H4)3] acts as the electron-proton sink in the ... Read more...

Trans-2,5-disubstituted tetrahydrofurans via addition of carbon nucleophiles to the strained bicyclic acetal 2,7-dioxabicyclo[2.2.1]heptane.

Sep 2009 Addition of allyltributylstannane to 2,7-dioxabicyclo[2.2.1]heptane in the presence of TiCl(4) produces 5-allyl-2-(hydroxymethyl)tetrahydrofuran with a trans/cis ratio of 93:7. The trans-selectivity is also observed in additions of various other ... Read more...
