Abstract: 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 (IC(50)=0.1 microM). 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).
