title: Synthesis and biological activity of pyrazo-[3,4-b]-pyridine derivatives. Part I.
abstract: 3 (3'-Morpholino-2'-hydroxypropoxy)--7--9 as well as 3 (3'-morpholino-2'-hydroxypropyloamino) 14 -- 16 derivatives of 1-methyl and 1-phenyl pyrazo-[3,4-b]-pyridines were prepared and screened for expected circulatory activity. Compounds 7, 11--14, 20 mg/kg, produced hypotension in cats; Compounds 7 and 14, 50--80 mg/kg, had antiarrhytmic action in BaCl2 -- induced arrhytmic in the rabbit.
