The remaining oil was purified by column chromatography (silica, heptane:EtOAc=8:1) to give butyl 1-{1-[1-(butoxycarbonyl)cyclopentyl]-6-isocyano-6-[(4-methylphenyl)sulfonyl]undecyl}-1-cyclopentanecarboxylate as a yellow oil (32.79 g). This oil (32.79 g) was dissolved in CH.sub.2Cl.sub.2 (400 mL), and cone aqueous HCl (150 mL) was added. After stirring vigorously for 4.5 h, H.sub.2O (500 mL) was added and the layers were separated. The aqueous phase was extracted with CH.sub.2Cl.sub.2 (2?100 mL) and the combined organic layers were washed with saturated H.sub.2O (200 mL), saturated aqueous NaHCO.sub.3 (500 mL) and brine (500 mL), dried (Na.sub.2SO.sub.4) and evaporated in vacuo. The remaining residue was purified by column chromatography (silica, heptane:EtOAc=6:1) to give butyl 1-{11-[1-(butoxycarbonyl)cyclopentyl]-6-oxoundecyl}-1-cyclopentanecarboxylate (24.11 g, 90% pure by .sup.1H NMR, 69%) as a slightly yellow liquid. .sup.1H NMR (CDCl.sub.3): ?=4.06 (t, J=6.6 Hz, 4H), 2.36 (t, J=7.4 Hz, 4H), 2.15-2.06 (m, 4H), 1.65-1.52 (m, 20H), 1.49-1.32 (m, 8H), 1.27-1.19 (m, 8H), 0.94 (t, J=7.4 Hz, 6H). .sup.13C NMR (CDCl.sub.3): ?=210.9, 177.6 (2?), 63.8 (2?), 54.0 (2?), 42.5 (2?), 38.9 (2?), 35.8 (4?), 30.6 (2?), 29.5 (2?), 25.6 (2?), 24.7 (4?), 23.4 (2?), 19.0 (2?), 13.5 (2?).

    [0286] LiOH.H.sub.2O (7.83 g, 187 mmol) and H.sub.2O (100 mL) were added to a solution of butyl 1-{11-[l-(butoxycarbonyl)cyclopentyl]-6-oxoundecyl}-1-cyclopentanecarboxylate (21.03 g, 90% pure by .sup.1H NMR, 37.3 mmol) in EtOH (300 mL) and the resulting mixture was stirred at reflux temperature for 2 d, allowed to cool to rt and concentrated in vacuo to a smaller volume. H.sub.2O (100 mL) was added and the resulting mixture was extracted with Et.sub.2O (100 mL), acidified with conc aqueous HCl (25 mL) and extracted with Et.sub.2O (3?150 mL). The latter organic layers were combined, dried (Na.sub.2SO.sub.4; To avoid loss of material, a minimal amount of Na.sub.2SO.sub.4 was used, with the desiccant becoming a white, oily paste. The organic layer was decanted from the desiccant.) and evaporated in vacuo.

    7.1 Effects of Illustrative Compounds of the Invention on NonHDL Cholesterol, HDL Cholesterol, Triglyceride Levels, Glycemic Control Indicators and Body Weight Control in Obese Female Zucker Rats

    [0288] In a number of different experiments, illustrative compounds of the invention are administered daily at a dose of up to 100 mg/kg to chow fed obese female Zucker rats for fourteen days in the morning by oral gavage in 1.5% carboxymethylcellulose/0.2% Tween 20 or 20% ethanol/80% polyethylene glycol (dosing vehicles). Animals are weighed daily. Animals are allowed free access to rodent chow and water throughout the study except on days of blood sampling where food is restricted for six hours prior to blood sampling. Blood glucose is determined after the 6 hour fast in the afternoon without anesthesia from a tail vein. Serum is also prepared from pretreatment blood samples subsequently obtained from the orbital venous plexus (with O.sub.2/CO.sub.2 anesthesia) and following the fourteenth dose at sacrifice from the heart following O.sub.2/CO.sub.2 anesthesia. Serums are assayed for lipoprotein cholesterol profiles, triglycerides, total cholesterol, Non-HDL cholesterol, HDL cholesterol, the ratio of HDL cholesterol to that of Non-HDL cholesterol, insulin, non-esterified fatty acids, and beta-hydroxy butyric acid. The percent body weight gain and the ratio of liver to body weight is also determined. These are shown as absolute values or as a percent change of the pretreatment values in Table 1.

    7.2 Effects of Illustrative Compounds of the Invention on the is Vitro Lipid Synthesis in Isolated Hepatocytes

    [0289] Compounds were tested for inhibition of lipid synthesis in primary cultures of rat hepatocytes. Male Sprague-Dawley rats were anesthetized with intraperitoneal injection of sodium pentobarbital (80 mg/kg). Rat hepatocytes were isolated essentially as described by the method of Seglen (Seglen, P. O. Hepatocyte suspensions and cultures as tools in experimental carcinogenesis. J. Toxicol. Environ. Health 1979, 5, 551-560). Hepatocytes were suspended in Dulbecco's Modified Eagles Medium containing 25 mM D-glucose, 14 mM HEPES, 5 mM L-glutamine, 5 mM leucine, 5 mM alanine, 10 mM lactate, 1 mM pyruvate, 0.2% bovine serum albumin, 17.4 mM non-essential amino acids, 20% fetal bovine serum, 100 nM insulin and 20 ?g/mL gentamycin) and plated at a density of 1.5?10.sup.5 cells/cm.sup.2 on collagen-coated 96-well plates. Four hours after plating, media was replaced with the same media without serum. Cells were grown overnight to allow formation of monolayer cultures. Lipid synthesis incubation conditions were initially assessed to ensure the linearity of [1-.sup.14C]-acetate incorporation into hepatocyte lipids for up to 4 hours. Hepatocyte lipid synthesis inhibitory activity was assessed during incubations in the presence of 0.25 ?Ci [1-.sup.14C]-acetate/well (final radiospecific activity in assay is 1 Ci/mol) and 0, 1, 3, 10, 30, 100 or 300 ?M of compounds for 4 hours. At the end of the 4-hour incubation period, medium was discarded and cells were washed twice with ice-cold phosphate buffered saline and stored frozen prior to analysis. To determine total lipid synthesis, 170 ?l of MicroScint-E? and 50 ?l water was added to each well to extract and partition the lipid soluble products to the upper organic phase containing the scintillant. Lipid radioactivity was assessed by scintillation spectroscopy in a Packard TopCount NXT. Lipid synthesis rates were used to determine the IC.sub.50s of the compounds that are presented in Table 2.
