Herein we report the first disclosure of biphenyl azoles that are nanomolar binders of adipocyte fatty acid binding protein (aFABP or aP2) with up to thousand-fold selectivity against muscle fatty acid binding protein and epidermal fatty acid binding protein. In addition a new radio-ligand to determine binding against the three fatty acid binding proteins(More)
Patients with abetalipoproteinemia, a disease caused by defects in the microsomal triglyceride transfer protein (MTP), do not produce apolipoprotein B-containing lipoproteins. It was hypothesized that small molecule inhibitors of MTP would prevent the assembly and secretion of these atherogenic lipoproteins. To test this hypothesis, two compounds identified(More)
Statins, which are inhibitors of 3-hydroxy-3-glutaryl-coenzyme A (HMG-CoA) reductase, decrease the hepatic biosynthesis of cholesterol by blocking the mevalonate pathway. Nitrogen-containing bisphosphonate drugs also inhibit the mevalonate pathway, preventing the production of the isoprenoids, which consequently results in the inhibition of osteoclast(More)
Muraglitazar, a novel dual (alpha/gamma) peroxisome proliferator-activated receptor (PPAR) activator, was investigated for its antidiabetic properties and its effects on metabolic abnormalities in genetically obese diabetic db/db mice. In db/db mice and normal mice, muraglitazar treatment modulates the expression of PPAR target genes in white adipose tissue(More)
The microsomal triglyceride (TG) transfer protein (MTP) is a heterodimeric lipid transfer protein that catalyzes the transport of triglyceride, cholesteryl ester, and phosphatidylcholine between membranes. Previous studies showing that the proximal cause of abetalipoproteinemia is an absence of MTP indicate that MTP function is required for the assembly of(More)
Muraglitazar/BMS-298585 (2) has been identified as a non-thiazolidinedione PPAR alpha/gamma dual agonist that shows potent activity in vitro at human PPARalpha (EC(50) = 320 nM) and PPARgamma(EC(50) = 110 nM). Compound 2 shows excellent efficacy for lowering glucose, insulin, triglycerides, and free fatty acids in genetically obese, severely diabetic db/db(More)
Squalene synthase catalyzes the reductive dimerization of two molecules of farnesyl diphosphate to form squalene at the final branchpoint of the cholesterol biosynthetic pathway. We report herein that isoprenyl 1,1-bisphosphonates and related analogs are potent inhibitors of rat microsomal squalene synthase (I50 = 0.7-32 nM). In addition, members of this(More)
Immune synovitis in rabbits was investigated as a potential in vivo model for evaluating new antiinflammatory agents. Antigen-induced increases in knee width as well as beta-glucuronidase and acid phosphatase activities in exudates were observed. Histologically, polymorphonuclear leukocytes appeared within hours in synovial tissues and reached maximum(More)
