We have identified a novel omega-hydroxy-alkanedicarboxylic acid, ESP 55016, that favorably alters serum lipid variables in obese female Zucker (fa/fa) rats. ESP 55016 reduced serum non-HDL-cholesterol (non-HDL-C), triglyceride, and nonesterified fatty acid levels while increasing serum HDL-C and beta-hydroxybutyrate levels in a dose-dependent manner. ESP(More)
High-density lipoprotein (HDL) is known to protect against atherosclerosis by promoting the reverse cholesterol transport. A new pathway for the regulation of HDL-cholesterol (HDL-c) removal involving F1-ATPase and P2Y13 receptor (P2Y13R) was described in vitro, and recently in mice. However, the physiological role of F1-ATPase/P2Y13R pathway in the(More)
The biological activity of some long hydrocarbon keto-diols (and their phosphate esters) and acids, has been correlated with their lipohilicity. IC50 values of the hepatocyte lipid synthesis inhibition (in vitro) were used to measure biological activity; lipohilicities were calculated by employing a 3D molecular size approach implemented in a QLogP software(More)
Steric hindrance to solvation disfavors structures like 1 synanti in which the melamine exposes to the solvent faces, such as tBu-H, for whom binding to the ring nitrogen is hindered but not blocked; steric hindrance to solvation lowers the barriers to rotation in solvents which bind the triazine nitrogens, therefore these solvents display the fastest rates(More)
Long hydrocarbon chain derivatives with bis-terminal hydroxyl or carboxyl groups and various central moieties (ketone, ether, ester, amide, carbamate, etc.) have been synthesized and evaluated for their effects on the de novo incorporation of radiolabeled acetate into lipids in primary cultures of rat hepatocytes as well as for their effects on lipid,(More)
Long hydrocarbon chain ethers with bis-terminal hydroxyl or carboxyl groups have been synthesized and evaluated for their potential to favorably alter lipid disorders including metabolic syndrome. Compounds were assessed for their effects on the de novo incorporation of radiolabeled acetate into lipids in primary cultures of rat hepatocytes as well as for(More)
Keto-substituted hydrocarbons with 11-19 methylene and bis-terminal hydroxyl and carboxyl groups have been synthesized and evaluated in both in vivo and in vitro assays for their potential to favorably alter lipid disorders including metabolic syndrome. Compounds were assessed for their effects on the de novo incorporation of radiolabeled acetate into(More)
A series of cycloalkyl-substituted oxo-alkanedicarboxylic acids have been prepared by the TosMIC methodology departing from haloalkyl-substituted cycloalkylcarboxylic esters. cyclopropyl derivatives showed IC(50) activity in the 0.3-1.0 microM range on the de novo incorporation of radiolabeled acetate into lipids in primary cultures of rat hepatocytes, and(More)
