, p. 4321 - 4322 (2007/10/03)
The reaction of 4-hydroxycoumarins with a series of quinonic chlorides under photostimulation was shown to provide an efficient approach to 3- alkylated coumarin derivatives. Alkylation reactions of this type proceeded via an electron transfer mechanism (
Diels-alder trapping of ortho-quinone methides. A new entry to substituted xanthene- 1,4-diones

Highly regioselective Diels-Alder reactions of a non-protected β-hydroxy quinone have been achieved after formation of chelated lithium alkoxides. In this report, we demonstrate on a model system, that the selectivity of reactions based on 1,3-dioxy-subst

Coupling reactions between vynylalanes and chloromethylated para-quinones, mediated by catalytic amounts of Ni(0), lead directly to allylated products, including coenzyme Q, and vitamins K1 and K2.

Borovkov, V. V.,Evstigneeva, R. P.,Makova, S. Z.
, p. 142 - 147 (2007/10/02)
Diquinone derivatives of deuteroporphyrin IX containing covalent bridges of different lengths between the chromophores have been synthesized.The compounds were prepared by the condensation of hydroxy-quinones with deuteroporphyrin IX using a mixed anhydri

The C-alkylation reaction of 2-chloromethyl-3,5,6-trimethyl-1,4-benzoquinone by 2-nitropropane anion is shown to proceed by the S(RN)1 mechanism. This mechanism is confirmed by the inhibitory effects of dioxygen, p-dinitrobenzene, cupric chloride and di-t

A novel series of (3-pyridylmethyl)benzoquinone derivatives was molecular designed and synthesized for the dual purpose of inhibiting thromboxane A2 and leukotriene biosynthesis enzymes and scavenging active oxygen species (AOS).They were evaluated for inhibition of TXA2 synthase, inhibition of 5-lipoxygenase, and for their scavenging activity of AOS using the thiobarbituric acid method. 2,3,5-Trimethyl-6-(3-pyridylmethyl)-1,4-benzoquinone (24, CV-6504) was the most promising derivative since it showed efficient AOS scavenging activity (inhibition of lipid peroxidation in rat brain homogenates: IC50 = 1.8 10-6 M) as well as potent, specific, and well-balanced inhibitory effects on both enzymes (inhibitory effect on TXA2 synthase in human blood, IC50 = 3.3 10-7 M; inhibitory effect on 5-lipoxygenase in human blood, IC50 = 3.6 10-7 M).In adriamycin-induced proteinuria in a rat model, compound 24 at 10 mg/kg per day (po) suppressed proteinuria by more than 50percent.The proteinuria, however, could not be reduced by single administration of an inhibitor specific for thromboxane A2 synthase or for 5-lipoxygenase .The proteinuria was also not reduced by administration of an AOS scavenger, 2-O-octadecylascorbic acid (4, CV-3611).Triple function compounds such as compound 24 that specifically inhibit both enzymes as well as scavenge AOS possess a variety of pharmacologically beneficial effects.
