Inhibition of hepatocellular carcinoma growth by blockade of glycosphingolipid synthesis
Hepatocellular carcinoma (HCC) is one of the most frequent cancers. In vitro studies suggest that growth and response to therapy of human carcinomas may depend on glycosphingolipid (GSL) expression. Glucosylceramide synthase (GCS), encoded by the gene Ugcg, is the basic enzyme required for the synthesis of GSLs. Gene array analysis implied that Ugcg is significantly overexpressed in human HCC a...
متن کاملCeramide synthase inhibition by fumonisin B1 treatment activates sphingolipid-metabolizing systems in mouse liver.
Sphingolipids are important components of cell structure and cell signaling. Both external and internal stimuli can alter levels of cellular sphingolipids by regulating enzyme activities associated with sphingolipid metabolism. Fumonisin B1, mycotoxin produced by Fusarium verticillioides, is a reportedly specific inhibitor of ceramide synthase. In order to test our hypothesis whether ceramide s...
متن کاملStructure, synthesis, and biosynthesis of fumonisin B1 and related compounds.
The absolute stereochemical description of fumonisin B1 (FB1) and presumably of its congeners is now secure. In this article I summarize studies leading to this conclusion and outline the biosynthetic and synthetic studies of FB1.

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
