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].
mGlu4 receptoragonist 1 (compound 62) is a highly effective positive allosteric modulator of mGlu4 receptors, displaying an EC 50 of 308 nM. Additionally, it exhibits noteworthy anxiolytic and antipsychotic properties [1].
Thrombin receptoragonist peptide (TRAP-14) is a 14-amino acid peptide agonist of the α-thrombin receptor. It induces aggregation of washed platelets as well as platelets in citrated and hirudin plasma. TRAP-14 (100 μM) increases the cytosolic calcium concentration in isolated guinea pig pulmonary smooth muscle cells 5-fold over baseline. It increases pulmonary arterial pressure in isolated guinea pig lung when used at a concentration of 1 μM, which is comparable to the effect induced by 10 nM α-thrombin. TRAP-14 also induces contraction of isolated rat aortic rings and increases endothelin-1 (ET-1) levels in a dose-dependent manner, an effect that is reversed by the ETA antagonist BQ-123 and the nitric oxide synthase (NOS) inhibitor L-NNA .
GLP-1 receptoragonist 3 is a GLP-1 receptoragonist,Example 4A-1, has EC50s of 1.1 nM and 13 nM in Clone H6 and Clone C6 cell lines assay, respectively.
APJ receptoragonist 1, a potent biphenyl acid derivative, acts as an agonist (EC50 of 0.093 nM and 0.12 nM for human and rat APJ receptors, respectively) for the APJ receptor (APJ-R). It exhibits significant in vitro potency towards apelin-13, the endogenous peptidic ligand for the APJ receptor. APJ receptoragonist 1 holds promise for heart failure research.
Glucocorticoid ReceptorAgonist-4 (Compound Preparation 5) serves as an agonist for glucocorticoid receptors and can be conjugated with TNF-α antibodies, facilitating research into autoimmune and inflammatory diseases [1].
