Mitogen activated protein kinases including c-Jun N-terminal kinase play an indispensable role in inflammatory diseases. Investigation of reported JNK-1 inhibitors indicated that diverse heterocyclic compounds bearing an amide group rendered potent JNK-1 inhibitory activity which prompted us to synthesize new JNK-1 inhibitors containing a pyrazole heterocyclic group. A DABCO mediated 1,3-dipolar cycloaddition reaction in neat resulted in pyrazole carboxylic acid which was converted to desired amides. Upon confirmation of the structures, all the compounds were screened for JNK-1 inhibitory activity and in vivo anti-inflammatory activity. Several synthesized analogues have exhibited JNK-1 inhibitory activity less than 10 μM, in particular compounds 9c, 10a and 10d were found to be potent among all the compounds.

2-Thio-3-chloroacrylamides undergo 1,3-dipolar cycloadditions with diazoalkanes leading to a series of novel pyrazolines and pyrazoles. The mechanistic and synthetic features of the cycloadditions to the 2-thio-3-chloroacrylamides at both the sulfide and sulfoxide levels of oxidation are rationalised on the basis of the nature of the substituents.
