New amino derivatives of pyrazolo[4,3-c]pyridine-7-carboxylic acids and esters have the general formula ##SPC1## Wherein R is hydrogen or lower alkyl; R.sub.1 is hydrogen, lower alkyl, phenyl or phenyl--(C.sub.1 -C.sub.2)-- lower alkyl; R.sub.2 is hydrogen, lower alkyl, phenyl or phenyl--(C.sub.1 -C.sub.2)-- lower alkyl; the group ##EQU1## forms one of the heterocyclic groups aziridono, pyrrolidino, piperidino, piperazino, 4-lower alkylpiperazino or 4-(hydroxy-lower alkyl)piperazino; R.sub.5 is hydrogen, lower alkyl or phenyl; and physiologically acceptable acid addition salts thereof. They are useful as ataractic, analgesic and antiinflammatory agents. In addition, the new compounds increase the intracellular concentration of adenosine-3',5'-cyclic monophosphate.
