| Hazard Information | Back Directory | [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. | [Uses]
K-14585 is a peptide competitive PAR2 antagonist. K-14585 inhibits PAR2-dependent IL-8 production, NF-κB phosphorylation, and p38 signaling. K-14585 reduces SLIGKV (PAR2 agonist peptide)-induced Ca2+ mobilisation in primary human keratinocytes[1][2][3]. | [IC 50]
