Shown are cardiotonically active 2-RR'N-5-PY-6-Q-nicotinonitriles where R is methyl or ethyl, R' is hydrogen or methyl, PY is 4- or 3-pyridinyl or 4- or 3-pyridinyl having one or two substituents, and Q is hydrogen or methyl, the latter only when R' is hydrogen, or pharmaceutically acceptable acid-addition salts thereof. Also shown are cardiotonic compositions and a method for increasing cardiac contractility using as active components 2-RR'N-5-PY-6-Q-nicotinonitriles or pharmaceutically acceptable acid-addition salts thereof, where R, R', PY and Q are defined as above. Also shown is the process for preparing said 2-RR'N-5-PY-6-Q-nicotinonitriles by reacting a 2-halo-5-PY-6-Q-nicotinonitrile with an amine of the formula RR'NH.
展示的是具有心脏强心作用的2-RR'N-5-PY-6-Q-烟酰腙,其中R为甲基或乙基,R'为氢或甲基,PY为4-或3-吡啶基或带有一或两个取代基的4-或3-吡啶基,Q为氢或甲基,仅当R'为氢时才为甲基,或其药学上可接受的酸加成盐。还显示了心脏强心组合物和使用2-RR'N-5-PY-6-Q-烟酰腙或其药学上可接受的酸加成盐作为活性成分来增加心脏收缩力的方法,其中R、R'、PY和Q的定义如上所述。还显示了通过将2-卤代-5-PY-6-Q-烟酰腙与RR'NH的胺反应制备所述2-RR'N-5-PY-6-Q-烟酰腙的过程。
