This invention relates to pyridine derivatives of the formulae: ##STR1## in which R.sup.1 is hydrogen, lower alkyl, aralkyl optionally substituted on the aromatic nucleus with at least a halogen atom or a hydroxy, nitro, amino, cyano, carboxy, alkoxycarbonyl, lower alkyl, lower alkoxy or trifluoromethyl group; R.sup.2 is hydrogen or lower alkyl; and R.sup.3 is hydrogen or at least a substituent selected from a halogen atom, a hydroxy, lower alkyl and lower alkoxy group, and their pharmaceutically acceptable inorganic or organic acid addition salts. Said compounds have particularly an anti-inflammatory and blood-platelet aggregation inhibiting activity.
本发明涉及以下式的吡啶衍生物:##STR1## 其中R.sup.1为氢、低碳基、芳基烷基,其芳香核上至少有一个卤素原子或羟基、硝基、氨基、氰基、羧基、烷氧羰基、低碳基、低碳氧基或三氟甲基基团的取代基;R.sup.2为氢或低碳基;R.sup.3为氢或至少为卤素原子、羟基、低碳基和低碳氧基团的取代基,以及它们的药学上可接受的无机或有机酸盐。这些化合物具有特别的抗炎和抑制血小板聚集活性。
