In homogeneous catalysis, catalysts are in the same phase as the reactants. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction.31906-04-4, Name is 4-(4-Hydroxy-4-methylpentyl)cyclohex-3-enecarbaldehyde, SMILES is C(C(C)(C)O)CCC1=CCC(CC1)C=O, belongs to quinuclidine compound. In a document, author is Ishihara, T, introduce the new discover, Recommanded Product: 4-(4-Hydroxy-4-methylpentyl)cyclohex-3-enecarbaldehyde.
Syntheses of 3-ethylidenequinuclidine derivatives as squalene synthase inhibitors. Part 2: Enzyme inhibition and effects on plasma lipid levels
Squalene synthase (E.C. 2.5.1.21) is a microsomal enzyme which catalyzes the reductive dimerization of two molecules of farnesyl diphosphate to form squalene, and is involved in the first committed step in cholesterol biosynthesis. It is an attractive target for hypocholesterolemic and hypotriglyceridemic strategies. We synthesized a series of 3-ethylidenequinuclidine derivatives, and evaluated their ability to inhibit squalene synthase in vitro and to lower non-HDL cholesterol levels in hamsters. 3-Ethylidene-quinuclidine derivatives incorporating an unsubstituted 9H-carbazole moiety reduced plasma non-HDL cholesterol levels and did not affect plasma transaminase levels, indicating a lack of hepatotoxicity. Among the novel Compounds, (Z)-2-[2-(quinuclidin-3-ylidene)ethoxy]-9H-carbazole hydrochloride 8 (YM-53579) and (E)-2-[2-fluoro-2-(quinuclidin-3-ylidene)ethoxy]-9H-carbazole hydrochloride 28 (YM-53601) were potent inhibitors of squalene synthase derived from human hepatoma cells, with IC50 Values Of 160 and 79 nM. respectively. They also reduced plasma non-HDL cholesterol levels in hamsters by approximately 50 and 70%, respectively. at all oral dose of 50 mg/kg/day for 5 days. (C) 2003 Elsevier Ltd. All rights reserved.
