Description: K-14585 is a proteinase-activated receptor 2 antagonist. Pretreatment with K-14585 inhibited PAR(2)-mediated p65 NFkappaB phosphorylation and NFkappaB-DNA binding. K-14585 inhibited SLIGKV-stimulated IL-8 production, but given alone increased IL-8. K-14585 antagonized PAR(2) competitively, resulting in inhibition of PAR(2)-mediated signalling and physiological responses both in vitro and in vivo. K-14585 could be useful in evaluating PAR(2)-mediated biological events and might lead to a new generation of therapeutically useful antagonists.
