Recommanded Product: 455-70-9. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Methyl 5-fluoro-3-pyridinecarboxylate, is researched, Molecular C7H6FNO2, CAS is 455-70-9, about Discovery of pyridone-containing imidazolines as potent and selective inhibitors of neuropeptide Y Y5 receptor.

A series of 2-pyridone-containing imidazoline derivatives was synthesized and evaluated as neuropeptide Y Y5 receptor antagonists. Optimization of the 2-pyridone structure on the 2-position of the imidazoline ring led to identification of 1-(difluoromethyl)-5-[(4S,5S)-4-(4-fluorophenyl)-4-(6-fluoropyridin-3-yl)-5-methyl-4,5-dihydro-1H-imidazol-2-yl]pyridin-2(1H)-one (7m, I). Compound 7m displayed statistically significant inhibition of food intake in an agonist-induced food intake model in SD rats and no adverse cardiovascular effects in anesthetized dogs. In addition, markedly higher brain penetrability and a lower plasma Occ90 value were observed in P-gp-deficient mdr1a (-/-) mice compared to mdr1a (+/+) mice after oral administration of 7m.
