The present invention relates to a substituted vinylpyridine derivative represented by the following formula (1): ##STR1## (wherein R.sup.1 represents a hydrogen atom, an alkyl group, etc., R.sup.2 represents an alkyl group; one of R.sup.3 and R.sup.4, which are different from each other, represents a hydrogen atom and the other represents a nitrile group, R.sup.5 represents an aryl group or a heteroaryl group, X represents an oxygen atom, etc., and one of Q.sup.1, Q.sup.2, and Q.sup.3 represents a nitrogen atom and the other two represent CH); a salt of the derivative; and a drug containing the derivative or salt as the active ingredient. Due to strong PDE inhibitory action and TNF-.alpha. production inhibitory action, the derivative, salt, and drug are useful for the prevention and treatment of a wide variety of inflammatory diseases and autoimmune diseases.
本发明涉及一种由以下式(1)表示的取代乙烯吡啶衍生物:##STR1##(其中R.sup.1代表氢原子、烷基等,R.sup.2代表烷基;R.sup.3和R.sup.4中的一个,二者不同,代表氢原子,另一个代表腈基,R.sup.5代表芳基或杂环芳基,X代表氧原子等,Q.sup.1、Q.sup.2和Q.sup.3中的一个代表氮原子,另外两个代表CH);该衍生物的盐;以及含有该衍生物或盐作为活性成分的药物。由于具有强烈的PDE抑制作用和TNF-α产生抑制作用,该衍生物、盐和药物对于预防和治疗各种炎症性疾病和自身免疫性疾病非常有用。
