title: Synthesis and biological properties of pyrazo-[3,4-B]-pyridine derivatives. II.
abstract: By aminoalkylation with diethylaminoethyl chloride of 3-hydroxypyrazo-[3,4-b]-pyridine 1 and its phenyl derivative 2 as well as 3-aminopyrazo-[3,4-b]-pyridine 7 and its phenyl derivative 8, basic ethers 5, 6 and aminoalkanoloamines 9 and 10 have been obtained. Compounds 5, 6 and 10 increased coronary blood flow of the isolated cat heart. At the concentration of 5 +/- 2 mg/ml shoved spasmolytic activity.
