Les composés de formule générale (I) dans laquelle D signifie le groupe Z-HET, -HET étant un hétérocycle à 5 chaînons tel que l'oxadiazolone (II) ou la thiazolidine dione (III) de formules (II et III) et -Z étant choisi dans le groupe constitué par -(CR1R2)n- et -(CR1=CR2)n; ou D signifie le groupe Z=HET, -Z- représentant, avec l'hétérocycle, un groupement -Z=HET de formule (IV) ou (V) dans laquelle -Z= représente -CR1=; sont utiles comme inhibiteurs spécifiques de la phospholipase A2 sécrétée non pancréatique humaine (PLA2-snph) de groupe (II), notamment en thérapie de pathologies inflammatoires.
Design of new potent and selective secretory phospholipase A2 inhibitors. Part 5: Synthesis and biological activity of 1-alkyl-4-[4,5-dihydro-1,2,4-[4H]-oxadiazol-5-one-3-ylmethylbenz-4′-yl(oyl)] piperazines
Among the different PLA(2)s identified to date, the group IIA secretory PLA(2) (sPLA(2) GIIA) is implied in diverse pathological conditions. In this work we describe the synthesis, inhibitory activities, and structure-activity relationships (SAR) of a new class of substituted piperazine derivatives. The in vitro fluorimetric assay using two groups of enzymes, GIB and GIIA, revealed several compounds as highly potent inhibitors (IC50 = 0.1 mu M). The in vivo activity assessed by ip or per os administration in a carrageenan-induced edema test in rats showed that two compounds proved to be as potent as indomethacin (10 mg/kg).
