Synthesized and natural pyridones/pyridines derivatives exhibiting diverse biological activities. 2-pyridone has lactam-lactim tautomerization like thymine and uracil bases. In this study, COX-2 target based series of pyridone/pyridine linked fleximers were designed, synthesized and studied. All analogues binding affinity with COX-2 active site were studied through molecular docking, and anti-inflammatory activity studied by in vivo analysis. Weak interactions were studied to find binding sites among analogues through crystal packing, Hirshfeld surface analysis and in silico analysis. All the analogues exhibited anti-inflammatory activity, while compound (3) is the most active analogue among the series. In contrast, since compound (3) is a pyridine-phthalimide ring-containing analogue, the presence of a phthalimide group probably favors anti-inflammatory activity over other types of rings. The results suggested further investigations on compounds as anti-inflammatory prodrugs.

Paragraph 0050-0061; 0065-0067, (2020/05/01)
The invention discloses a preparation method of aclidinium bromide key intermediate 3-phenoxypropyl bromide (formula I). The method comprises the following steps: by taking phenol and halogenated propanol as raw materials, carrying out nucleophilic substitution reaction under an alkaline condition to generate 3-phenoxy propanol, then reacting with a sulfonic acid esterification reagent to generateactive ester of 3-phenoxy propanol, refining the ester, and then reacting with a bromide of an alkali metal to generate 3-phenoxypropyl bromide. The preparation method provided by the invention has the advantages of cheap and easily available raw materials, simple operation, mild reaction conditions, no harsh reaction conditions, and high yield and purity of the obtained product, and is suitablefor industrial production.
