pyridine/fever

The present invention relates to 2-amino-5-oxo-5 H-[1]benzopyrano[2,3-b]pyridine-3-carboxylic acid derivatives of the formula (I): ##STR3## wherein A is ##STR4## (R, R.sup.1 and R.sup.2 are independently hydrogen or lower alkyl and m is 0 or 1, with the proviso that when m is 1, R.sup.1 is hydrogen)

The present invention is concerned with 11-oxo-1-benzoxepino[4,3-c]pyridines of Formula I: ##STR2## wherein R.sub.1 and R.sub.2 may be hydrogen, lower alkyl, cyano, carboxamido, carboxy, ethoxycarbonyl or tetrazolyl and R.sub.3 may be hydrogen, lower alkyl, halogen, hydroxy or lower alkoxy. In the

BACKGROUND OF THE INVENTION It is an object of this invention to provide novel 6-phenyl-2,3-bis(4-methoxyphenyl)pyridine derivatives. These compounds are active as prostaglandin synthetase inhibitors, analgesic agents, anti-inflammatory agents, anti-arthritic agents, antipyretic agents, and
