S-Adenosylmethionine (AdoMet) concentrations are highly elevated in tissues and biol. fluids of patients affected by S-adenosylhomocysteine hydrolase deficiency. This disorder is clin. characterized by severe neurol. symptoms, whose pathophysiol. is not yet established. Therefore, we investigated the effects of intracerebroventricular administration of AdoMet on redox homeostasis, microglia activation, synaptophysin levels, and TAU phosphorylation in cerebral cortex and striatum of young rats. AdoMet provoked significant lipid and protein oxidation, decreased glutathione concentrations, and altered the activity of important antioxidant enzymes in cerebral cortex and striatum. AdoMet also increased reactive oxygen (2′,7′-dichlorofluorescein oxidation increase) and nitrogen (nitrate and nitrite levels increase) species generation in cerebral cortex. Furthermore, the antioxidants N-acetylcysteine and melatonin prevented most of AdoMet-induced pro-oxidant effects in both cerebral structures. Finally, we verified that AdoMet produced microglia activation by increasing Iba1 staining and TAU phosphorylation, as well as reduced synaptophysin levels in cerebral cortex. Taken together, it is presumed that impairment of redox homeostasis possibly associated with microglia activation and neuronal dysfunction caused by AdoMet may represent deleterious pathomechanisms involved in the pathophysiol. of brain damage in S-adenosylhomocysteine hydrolase deficiency. In the experiment, the researchers used many compounds, for example, 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0Application In Synthesis of 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one).
2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0) belongs to benzofurans derivatives. Benzofuran is a core structural unit found in many naturally occurring compounds with multidirectional biological activities. Benzofurans are stable towards alkali and readily polymerize on treatment with sulfuric acid, due to which they are useful for the preparation of low cost chemically relatively inert resins.Application In Synthesis of 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one
