This invention provides novel tertiary aminoindazole compounds of the following general formula: ##SPC1## Wherein R represents a hydrogen or halogen atom; R.sub.1 represents an alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted aralkyl group; R.sub.2 and R.sub.3 both represent a lower alkyl or aralkyl group and W represents a branched chain alkylene group, and salts, especially acid addition and quaternary ammonium salts thereof, and processes for making them. Such compounds are pharmacologically active in that they exhibit antiinflammatory and analgesic effects so the invention also provides pharmaceutical compositions containing one or more of these compounds as the active ingredient. They are also useful anti-microbial agents.

Novel amino-indazole compounds

Certain 2-substituted-4-substituted-1(2H)-phthalazinone compounds have hypotensive activity. Such compounds are used in pharmaceutical compositions. Processes of preparing them and the intermediate compounds are disclosed.

Novel phthalazinone compounds

Novel 1,4-disubstituted piperazine compounds and pharmaceutical compositions incorporating such compounds in conjunction with orally, parenterally or rectally administrable pharmaceutically acceptable carriers are disclosed. These compounds have coronary vasodilating properties. Also disclosed are processes for preparing these compounds, and novel intermediate compounds used in such processes.
