in addition to these mechanisms , recent work suggests the diversion of arachidonic acid ( aa ) metabolism via the lipoxygenase pathway ( especially after cyclo-oxygenase inhibition by aspirin and indomethacin ) , thereby leading to the formation of a new class of biologically active lipids : hydroperoxy acids ( hpete and hete ) , leukotrienes ( lta , b , c , d , e ) and srs or srs-a ( ltc , ltd ) .
