  Identification of positron emission tomography ligands for NPY Y5 receptors in the brain

  摘要：

  A series of trans-3-oxospiro[(aza)isobenzofuran-1(3H),1'-cyclohexane]-4'-carboxamide derivatives were synthesized and profiled for NPY Y5 binding affinity, brain and CSF penetrability in rats, and susceptibility to human and mouse P-glycoprotein transporters in order to develop a PET ligand. Compound 12b exhibited an acceptable profile for a PET ligand, and [C-11]12b was successfully utilized in clinical settings as a Y5 PET ligand. (C) 2009 Elsevier Ltd. All rights reserved.

  ole NPY Y5 receptor antagonists are described. Optimization of the lead compound 2a by incorporating substituents into the 5-position or into both the 5- and 6-positions of the benzimidazole core part led to the identification of 5-(5-methyl-1,2,4-oxadiazol-2-yl)benzimidazole (2r: IC(50)=3.3 nM) and 5-(2-methyltetrazol-5-yl)benzimidazole (2u: IC(50)=5.9 nM), both of which are potent, selective, and

  A series of trans-3-oxospiro[(aza)isobenzofuran-1(3H),1'-cyclohexane]-4'-carboxamide derivatives were synthesized to identify potent NPY Y5 receptor antagonists. Of the compounds, 21j showed high Y5 binding affinity, metabolic stability and brain and cerebrospinal fluid (CSF) penetration, and low susceptibility to P-glycoprotein transporters. Oral administration of 21j significantly inhibited the Y5 agonist-induced food intake in rats with a minimum effective dose of 1 mg/kg. This compound was selected for proof-of-concept studies in human clinical trials. (C) 2009 Elsevier Ltd. All rights reserved.

  Spiro-isobenzofuranones 1a and 1b were discovered as potent, selective, and brain-penetrable non-imidazole H-3 receptor inverse agonists. Our corporate sample collection was screened to identify 2a as a lead. Recognizing the right-hand portion of 2a as an essential pharmacophore, an extensive screen of the left-hand piperidine portion was carried out to yield the potent spiro-derivatives 2t-x. Spiro-isobenzofuranone 2x, the most potent among the derivatives, was converted to the corresponding amide 1a, which possessed dramatically improved H3 activity (IC50 = 0.72 nM; more than 20-fold improvement over 2x). Further elaboration led to the identification of 1b, a 5-methoxy derivative with an IC50 of 0.54 nM. Our studies demonstrated that derivatives 1a and 1b to be potent, selective, and brain-penetrable H-3 inverse agonists. (C) 2008 Elsevier Ltd. All rights reserved.
