摘要

The use of condensed (hetaryl-substituted) 1-benzal-3-pyrazol derivates of general formula (I) as vasodilators; wherein R1 is hydrogen, hydroxyl, alkyl or alkoxy, R2 is a radical of formula (II); wherein R5 is hydrogen, halogen, alkyl, alkoxy, carbonyl or a radical of formula -CH2-OR6, in which R6 is hydrogen or alkyl, R3 and R4 together for a radical of formula (III), wherein R7 is hydrogen, halogen, hydroxyl, alkyl of alkoxy.
