  Long Hydrocarbon Chain Keto Diols and Diacids that Favorably Alter Lipid Disorders in Vivo

  摘要：

  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 lipids in primary cultures of rat hepatocytes as well as for their effects on lipid and glycemic variables in obese female Zucker fatty rats [Crl:(ZUC)-faBRI following 1 and 2 weeks of oral administration. The most active compounds were found to be symmetrical with four to five methylene groups separating the central ketone functionality and the gem dimethyl or methyl/aryl substituents. Furthermore, biological activity was found to be greatest in both in vivo and in vitro assays for the tetramethyl-substituted keto diacids and diols (e.g., 10c, 10g, 14c), and the least active were shown to be the bis(arylmethyl) derivatives (e.g., 10e, 10f, 14f). Compound 14c dose-dependently elevated HDL-cholesterol, reduced triglycerides, and reduced NEFA, with a minimum effective dose of 30 mg/kg/day. Compound 10g dose-dependently modified non-HDL-cholesterol, triglycerides, and nonesterified fatty acids, with a minimum effective dose of 10 mg/kg/day. At this dose, compound 10g elevated HDL-cholesterol levels 2-3 times higher than pretreatment levels, and a dose-dependent reduction of fasting insulin and glucose levels was observed.

  A series of phenylenebis(oxy)bis[2,2-dimethylpentanoic acid]s have been synthesized and evaluated as potential hypolipidemic agents. Compound 18 (CI-924) was found to be the most potent compound in this series. In rats, compound 18 not only reduced low-density lipoprotein cholesterol but also increased high-density lipoprotein (HDL) cholesterol. Comparative studies in rats indicated 18 produced an

  已经合成了一系列亚苯基双（氧基）双[2,2-二甲基戊酸]，并被评估为潜在的降血脂药。发现化合物18（CI-924）是该系列中最有效的化合物。在大鼠中，化合物18不仅降低了低密度脂蛋白胆固醇，还增加了高密度脂蛋白（HDL）胆固醇。在大鼠中进行的比较研究表明，在吉非贝齐所需剂量的三分之一处，18产生的HDL胆固醇水平相同。讨论了构效关系。

  structure--activity relationships of imidazole derivatives as inhibitors of thromboxane (TX) synthetase were investigated. Introduction of various substituents (e.g., one or two methyl groups, a halogen atom, a methylidene group, unsaturated bonds, or a phenylene group) into the alpha position or other positions in the carboxy-bearing side chain of 1-(7-carboxyheptyl)imidazole (15) was found to increase the
