ABSTRACT:
This invention relates to new thieno [3,2-c] pyridine derivatives having the formula: ##STR1## 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 ##STR2## in which R.sub.1 and R.sub.2 are each independently of each other, hydrogen or a straight or branched lower alkyl group; or R.sub.1 and R.sub.2 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 ##STR3## 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.
