Letavic M, Aluisio L, Atack J, Bonaventure P, Carruthers N, Dugovic C, et al.
Bioorg Med Chem Lett . 2010 Jun; 20(14):4210-4. PMID: 20561786
The pre-clinical characterization of novel aryloxypyridine amides that are histamine H(3) receptor antagonists is described. These compounds are high affinity histamine H(3) ligands that penetrate the CNS and occupy the...

Letavic M, Keith J, Ly K, Bonaventure P, Feinstein M, Lord B, et al.
Bioorg Med Chem Lett . 2008 Oct; 18(21):5796-9. PMID: 18922693
The synthesis and biological activity of a new series of 2-aryloxymethylmorpholine histamine H(3) antagonists is described. The new compounds are high affinity histamine H(3) ligands that penetrate the CNS and...

Keith J, Apodaca R, Xiao W, Seierstad M, Pattabiraman K, Wu J, et al.
Bioorg Med Chem Lett . 2008 Aug; 18(17):4838-43. PMID: 18693015
A series of thiadiazolopiperazinyl aryl urea fatty acid amide hydrolase (FAAH) inhibitors is described. The molecules were found to inhibit the enzyme by acting as mechanism-based substrates, forming a covalent...

Bembenek S, Keith J, Letavic M, Apodaca R, Barbier A, Dvorak L, et al.
Bioorg Med Chem . 2008 Feb; 16(6):2968-73. PMID: 18249544
Currently, the only clinically effective treatment for Alzheimer's disease (AD) is the use of acetylcholinesterase (AChE) inhibitors. These inhibitors have limited efficacy in that they only treat the symptoms and...
