protease activated receptor 1, par 1 agonist

Protease-Activated Receptor-1 (PAR-1) Agonist, a selective peptide, activates the PAR-1 receptor by mimicking the specific actions of thrombin. It corresponds to the PAR1 tethered ligand, facilitating selective activation of this receptor.

Protease-Activated Receptor-1, PAR-1 Agonist acetate 是一种选择性蛋白酶激活受体 1 (PAR-1) 激动剂肽。 它对应于 PAR1 栓系配体，可以选择性地模拟凝血酶通过该受体的作用。

Protease-Activated Receptor-1 (PAR-1) Agonist TFA is a selective peptide that acts as an agonist for the proteinase-activated receptor-1 (PAR-1). Corresponding to the tethered ligand of PAR-1, this compound mimics the actions of thrombin through the PAR-1 receptor[1][2].

PAR2 (1-6) amide is a synthetic peptide agonist of proteinase-activated receptor 2 (PAR2) that corresponds to residues 1-6 of the amino terminal tethered ligand sequence of human PAR2 and residues 37-42 of the full-length sequence.1It binds to NCTC 2544 cells expressing human PAR2 (Ki= 9.64 μM in a radioligand binding assay) and induces calcium mobilization in the same cells (EC50= 0.075 μM).2PAR2 (1-6) amide (100 μM) reduces colony formation of A549 lung cancer cells.1It induces superoxide production and degranulation in isolated human eosinophils when used at a concentration of 500 μM.3PAR2 (1-6) amide (5 μmol/kg) induces tear secretion in rats when used in combination with amastatin .4 1.Bohm, S.K., Kong, W., Bromme, D., et al.Molecular cloning, expression and potential functions of the human proteinase-activated receptor-2Biochem.
