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.
本发明涉及具有以下式子的新的噻吩[3,2-c]吡啶衍生物:##STR1## 其中:Y代表羟基或OR基团,其中R为直链或支链低碳基基团,或Y代表##STR2## 其中R.sub.1和R.sub.2各自独立地代表氢或直链或支链低碳基基团;或R.sub.1和R.sub.2一起形成与它们连接的氮原子的杂环,其中可能包括第二个杂原子,例如氧或氮,后者可以被一个可以被取代的低碳基或苄基基团所取代;X代表氢、卤素或低碳基基团;以及其与药学上可接受的矿物质或有机酸的加成盐,如果Y代表OR或##STR3## 或者与矿物质碱的加成盐,如果Y代表OH,以及两个对映体或其混合物。本发明还涉及新的噻吩[3,2-c]吡啶衍生物的制备过程及其作为抑制血小板聚集剂和抗血栓剂的治疗应用。
