Molecular pathological pathways leading to multi-organ failure in critical illness are progressively being unravelled. However, attempts to modulate these pathways have not yet improved the clinical outcome. Therefore, new targetable mechanisms should be investigated. We hypothesize that increased dicarbonyl stress is such a mechanism. Dicarbonyl stress is the accumulation of dicarbonyl metabol...

A novel polysaccharide fraction (BCP-1) was extracted from the black currant fruit by ultrasound-assisted compound enzyme and purified by chromatography on macroporous resin D4006, anion-exchange Q-Sepharose FF and Sephadex G-100 columns. BCP-1 consisted of galacturonic acid, xylose, mannose, glucose and galactose in a ratio of 1.00:3.14:1.83:17.90:1.98 and its molecular weight was 14,050 Da. T...

A highly regio-, chemo-, diastereo- and enantioselective organocatalytic [4 + 1] annulation of 2-halo-1,3-dicarbonyl compounds with Morita-Baylis-Hillman adducts catalyzed by commercially available, low cost quinidine for the preparation of synthetically unique and medicinally multi-functionalized isoxazoline N-oxides with three stereogenic centers including adjacent quaternary and tertiary ste...

The reaction of cyanothioacetamide with aromatic aldehydes and 1,3-dicarbonyl compounds followed by aminomethylation or S-alkylation gave a series heterocyclic derivatives 1,2,3,4-tetrahydropyridine 1,4,5,6,7,8-hexahydroquinoline fragment. resulting were tested for analgesic activity in vivo. Some the prepared showed an antinociceptive effect superior to that ketorolac dynamics.

A sequential process strategy was introduced for the synthesis of 2,3,4,5-tetrasubstituted pyrroles by the formation of benzoin from the corresponding aromatic aldehyde and followed by condensation reaction with 1,3-dicarbonyl compounds and ammonium acetate in the presence of diethylene glycol-bis(3-methylimidazolium) dihydroxide as catalyst in refluxing ethanol. The recycled catalyst could be ...
