CC chemokines and their receptors play a key role in mediating both physiological and pathological processes. Chemokine receptors have been widely recognized as attractive drug targets by the pharmaceutical industry. A number of small molecule chemokine receptor antagonists have been developed for different disease indications, including rheumatoid(More)
OBJECTIVE Investigation was conducted to understand the mechanism of action of diacylglycerol acyltransferase 1 (DGAT1) using small molecules DGAT1 inhibitors, compounds K and L. DESIGN AND METHODS Biochemical and stable-label tracer approaches were applied to interrogate the functional activities of compounds K and L on TG synthesis and changes of carbon(More)
The use of stable isotopically labeled substrates and analysis by mass spectrometry have provided substantial insight into rates of synthesis, disposition, and utilization of lipids in vivo. The information to be gained from such studies is of particular benefit to therapeutic research where the underlying causes of disease may be related to the production(More)
Angiopoietins and Tie2 receptor were recently identified as an endothelial cell-specific ligand-receptor system that is critical for vascular development and postnatal pathologic angiogenesis by mediating vascular integrity. In this study, we identified a series of small-molecule Tie2 inhibitors, which blocked Ang1-induced Tie2 autophosphorylation and(More)

Diacylglycerol acyltransferase-1 (DGAT1) is a potential therapeutic target for treatment of obesity and related metabolic diseases. However, the degree of DGAT1 inhibition required for metabolic benefits is unclear. Here we show that partial DGAT1 deficiency in mice suppressed postprandial triglyceridemia, led to elevations in glucagon-like peptide-1(More)
Monocyte infiltration is implicated in a variety of diseases including multiple myeloma, rheumatoid arthritis, and multiple sclerosis. C-C chemokine receptor 1 (CCR1) is a chemokine receptor that upon stimulation, particularly by macrophage inflammatory protein 1alpha (MIP-1alpha) and regulated on normal T-cell expressed and secreted (RANTES), mediates(More)
We report the design and synthesis of a series of novel DGAT1 inhibitors in the benzimidazole class with a pyridyl-oxy-cyclohexanecarboxylic acid moiety. In particular, compound 11A is a potent DGAT1 inhibitor with excellent selectivity against ACAT1. Compound 11A significantly reduces triglyceride excursion in lipid tolerance tests (LTT) in both mice and(More)
The discovery, synthesis and preliminary SAR of a novel class of non-peptidic antagonists of the alpha(v)-integrins alpha(v)beta(3) and alpha(v)beta(5) is described. High-throughput screening of an extensive series of ECLiPStrade mark compound libraries led to the identification of compound 1 as a dual inhibitor of the alpha(v)-integrins alpha(v)beta(3) and(More)
A novel series of pyrrolidine heterocycles was prepared and found to show potent inhibitory activity of CCR1 binding and CCL3 mediated chemotaxis of a CCR1-expressing cell line. A potent, optimized triazole lead from this series was found to have acceptable pharmacokinetics and microsomal stability in rat and is suitable for further optimization and(More)
