Journal ArticleDOI
Insight into steroid scaffold formation from the structure of human oxidosqualene cyclase
Ralf Thoma,Tanja Schulz-Gasch,Brigitte D'Arcy,Jörg Benz,Johannes Aebi,Henrietta Dehmlow,Michael Hennig,Martine Stihle,Armin Ruf +8 more
TL;DR: The target protein with an inhibitor that showed cholesterol lowering in vivo opens the way for the structure-based design of new OSC inhibitors, and the complex with the reaction product lanosterol gives a clear picture of the way in which the enzyme achieves product specificity in this highly exothermic cyclization reaction.
Journal ArticleDOI
Stereoselektive Alkylierung an C(α) von Serin, Glycerinsäure, Threonin und Weinsäure über heterocyclische Enolate mit exocyclischer Doppelbindung†‡
TL;DR: Steroselective alkylation at C(α) of Serine, Clyceric acid, Threonine, and Tartaric acid Involving Heterocyclic Enolates with Evocyelic double bonds as discussed by the authors.
Journal ArticleDOI
Ro 48-8.071, a new 2,3-oxidosqualene:lanosterol cyclase inhibitor lowering plasma cholesterol in hamsters, squirrel monkeys, and minipigs: comparison to simvastatin.
Olivier Morand,Johannes Aebi,Henrietta Dehmlow,Yu-Hua Ji,N Gains,Hans Lengsfeld,Jacques Himber +6 more
TL;DR: Findings clearly differentiate the OSC inhibitor Ro 48-8.071 from simvastatin, and support the view that OSC is a distinct key component in the regulation of the cholesterol synthesis pathway.
Journal ArticleDOI
Enantioselektive α‐Alkylierung von Asparagin‐ und Glutaminsäure über die Dilithium‐enolatocarboxylate von 2‐[3‐Benzoyl‐2‐(tert‐butyl)‐1‐methyl‐5‐oxoimidazolidin‐4‐yl]essigsäure und 3‐[3‐Benzoyl‐2‐(tert‐butyl)‐1‐methyl‐5‐oxoimidazolidin‐4‐yl]propionsäure

TL;DR: The pure methyl esters of the heterocyclic carboxylic acids specified in the title were prepared in several steps by known methods from aspartic and glutamic acid, with overall yields of ca. 20%.
Journal ArticleDOI
Synthesis and structure-activity studies of novel orally active non-terpenoic 2,3-oxidosqualene cyclase inhibitors.
Henrietta Dehmlow,Johannes Aebi,Synese Jolidon,Yu-Hua Ji,Elisabeth von der Mark,Jacques Himber,Olivier Morand +6 more
TL;DR: The approach combined testing of the compounds first for increased binding affinity and for increased stability in vitro, and most promising compounds were then evaluated for their efficacy in lowering plasma total cholesterol (TC) and plasma low-density lipoprotein cholesterol (LDL-C) in hyperlipidemic hamsters.
