In the present investigation, series of Bis (heterocycle)s bearing pyrazoline in combination of the imidazole derivatives have been synthesized via 1,3-dipolar cycloaddition reactions of N-(nitrobenzyl)-imidazole nitrile imines with different dipolarophiles. All the newly synthesized compounds were characterized and screened for analgesic-anti-inflammatory activities and were compared with the standard drugs. The compounds exhibited excellent anti-inflammatory and analgesic activities. Out of the compounds studied 4b, 4d and 4g compounds shown statistically significant activity comparable to the standard drugs Ibuprofen and Aspirin at the same dose.
