DESCRIPTION:
BRIEF SUMMARY
FIELD OF INVENTION
This invention relates to novel cyclopentapyrazole and tetrahydroindazole compounds and to the use of those compounds as anti-asthmatic agents, antiinflammatory agents or intermediates.
Structurally, the compounds of this invention are composed of a 1,3 substituted pyrazole ring additionally substituted at the four and five positions by a saturated cyclic ring of 5 or 6 carbon atoms.
