NYA TIENO-3,2-C-PYRIDINDERIVAT, DERAS FRAMSTAELLNINGSMETODER OCH TERAPEUTISKA ANVAENDNING

摘要

This invention relates to new thieno [3,2-c] pyridine derivatives having the formula: (I) in which: Y represents the OH group or an OR group in which R is a straight or branched lower alkyl radical, or Y represents a group in which R1 and R2 are each independently of each other, hydrogen or a straight or branched lower alkyl group; or R1 and R2 form together and with the nitrogen atom to which they are attached a heterocycle which may include a second heteroatom such as oxygen or nitrogen, wherein the latter may be substituted by a lower alkyl or benzyl radical which may be substituted; and X represents hydrogen, a halogen or a lower alkyl radical; and their addition salts with pharmaceutically acceptable mineral or organic acids if Y represents the group OR or or with mineral bases if Y represents OH, as well as the two enantiomers or their mixture. The invention also relates to the preparation process of new thieno [3,2-c] pyridine derivatives and to their therapeutic application as blood-platelet aggregation inhibiting agents and antithrombotics.
