摘要：

Syntheses and structure-activity relationships of a novel class of 2-[3-oxospiro[isobenzofuran-1(3H), 1'-cyclohexan]-4'-yl]benzimidazole 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 orally bioavailable Y5 receptor antagonists.
