3,4-Dihydro-2-phenyl-2H-pyrano[2,3-b]pyridines with potent antirhinovirus activity
摘要:
A general synthesis to the title compounds 1, substituted in the 6-position and on the phenyl ring, is outlined. Eighteen analogues were compared with respect to in vitro activity against rhinovirus types 1A, 9, and 64. Compounds 1c and 1h, the 6-bromo- and 6-(methylsulfonyl)-3',4'-dichlorophenyl analogues, afforded median MIC50 values against 23 rhinovirus serotypes of 0.05 and 0.13 micrograms/mL, respectively. Mice dosed orally with 200 mg/kg of 1c or 1h exhibited serum levels well in excess of each compound's MIC50, indicating that some analogues have the potential to be orally effective drugs.

2-Phenylpyrano[2,3-b]pyridines are described herein. These compounds are active against a variety of viruses. A number of procedures can be used to prepare the compounds of this invention but, at some point, they would all make use of the cyclization of a (phenyl) (pyridyl)propanol or (phenyl) (pyridyl)propenol.
