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.

Price and Availability




K-14585 is not in stock, but may be available through custom synthesis. For cost-effective reason, minimum 1 gram order is requested. The product will be characterized by NMR, HPLC and MS analysis. Purity (HPLC) is usually >98%. CoA, QC data, MSDS will be provided when product is successfully made. The estimated lead time is 2-3 months. Please send email to sales@medkoo.com to inquire quote.
