Cytosolic phospholipase A(2)alpha (cPLA(2)alpha) and fatty acid amide hydrolase (FAAH) are enzymes, which have emerged as attractive targets for the development of analgetic and anti-inflammatory drugs. We recently reported that 1-[3-(4-octylphenoxy)-2-oxopropyl]indole-5-carboxylic acid (10) and related compounds are inhibitors of cPLA(2)alpha. Since cPLA(2)alpha and FAAH possess several common structural features, we now screened this substance series together with some new derivatives for FAAH inhibition. Some of the assayed compounds proved to be selective cPLA(2)alpha inhibitors, while others showed high FAAH and moderate cPLA(2)alpha inhibitory potency. Furthermore, several derivatives were favorably active against both enzymes and, therefore, could represent agents, which have improved analgetic and anti-inflammatory qualities in comparison with selective cPLA(2)alpha and FAAH inhibitors.
