This paper describes the preparation of 1,2,3-triazole derivatives of salicylic acid from the methyl 4-azidosalicylate, by 1,3-dipolar cycloaddition reactions to beta-ketoesters, beta-ketoamides, beta-diketones and to symmetrical or asymmetrical alkynes. Other derivatives were obtained by hydrolysis and decarboxylation reactions. Some compounds were evaluated for antiinflammatory activity by an in vitro test based upon the inhibition of the cyclooxygenase enzyme, but they generally showed a weak activity.

Arachidonic acid (AA) signaling is upregulated in the caudate-putamen and frontal cortex of unilaterally 6-hydroxydopamine (6-OHDA) lesioned rats, a model for asymmetrical Parkinson disease. AA signaling can be coupled to D(2)-like receptor initiated AA hydrolysis from phospholipids by cytosolic phospholipase A(2) (cPLA(2)) and subsequent metabolism by cyclooxygenase (COX)-2. In unilaterally 6-OHDA- and sham-lesioned rats, we measured brain expression of cPLA(2), other PLA(2) enzymes, and COX-2. Activity and protein levels of cPLA(2) were significantly higher as was COX-2-protein in caudate-putamen, frontal cortex and remaining brain on the lesioned compared to intact side of the 6-OHDA lesioned rats, and compared to sham brain. Secretory sPLA(2) and Ca(2+)-independent iPLA(2) expression did not differ between sides or groups. Thus, the tonically increased ipsilateral AA signal in the lesioned rat corresponds to upregulated cPLA(2) and COX-2 expression within the AA metabolic cascade, which may contribute to symptoms and pathology in Parkinson disease.
