Description

General description

Native proteinase activated receptor-2- (PAR-2) specific agonist, SLIGRL-NH₂, modified with an N-terminal furoyl group to increase its potency and resistance to metabolic degradation. Shown to activate [Ca²⁺]_i mobilization in PAR-2-expressing cells (EC₅₀ = 253 nM in HCT-15 cells) in vitro. Also induces PAR-2-mediated salivation (ED₅₀ = 30 nmol/kg, i.v.) in vivo. Exhibits no effects on PAR-2^-/- mice. Reactive towards human, rat, and mouse PAR-2.
