    摘要: Thienopyridine derivatives of the formula: ##STR1## wherein the symbol A represents pyrid-3-yl, isoquinol-5-yl, or a 3-alkylisoquinol-5-yl group in which the alkyl radical is of 1 through 10 carbon atoms, and one of the symbols X and Y represents a single bond and the other represents the vinylene radical, are new compounds possessing useful pharmacological properties. They are particularly useful as anti-viral agents and, in certain cases, as analgesics, anti-inflammatory agents and anti-pyretics.
