Arrestin

ELA-14(human) acetate is a fragment of ELA that binds to APJ, activates the Gαi1 and β-arrestin-2 signaling pathways, and induces receptor internalization similarly to its parent endogenous peptide.

Barbadin is a novel and specific inhibitor of β-arrestin β2-adaptin interaction with an IC50 value of 19.1 μM for β-arestin1 and 15.6 μM for β-arestin2. Barbadin potentiates the long term effects of lorcaserin on POMC neurons and weight loss. Barbadin potentiates the long-term effects of lorcaserin on POMC neurons and weight loss, blocks agonist-promoted endocytosis of prototypic β2-adrenergic, V2-vasopressin, and angiotensin-II-1 receptors, and may be useful in the study of obesity.

TRV-120027 acetate is a β-arrestin-1-biased agonist of the angiotensin II receptor type 1 (AT1 receptor) and engages -arrestins while blocking G-protein signaling.

CCX777 is a partial agonist recruited to ACKR3 by β-arrestin-2 and is used in cancer research.

7-FluorotryptaMine HCl is a potent aromatic monoamine GPRC5A agonist that induces GPRC5A-mediated β-arrestin recruitment.7-FluorotryptaMine HCl can be used to study signalling pathways related to immunity and cancer.

TRV120027 TFA is a β-arrestin-1-biased agonist of the angiotensin II receptor type 1 (AT1R) and engages ß-arrestins while blocking G-protein signaling.

VUF11207 fumarate is an agonist of CXCR7 and a high-potency ligand of CXCR7 (pKi: 8.1).

ML221 is a potent apelin /APJ functional antagonist, inhibiting apelin-13-mediated activation of APJ, with IC50s of 0.70 μM in the cAMP assay, and 1.75 μM in the β-arrestin assay, and EC80 of 10 nM in both assays.

ML417 is a selective and brain-penetrant agonist of D3 dopamine (EC50: 38 nM).

ML192 (CID1434953) is a selective GPR55 ligand antagonist. ML192 is an inhibitor that inhibits β-arrestin transport, ERK1/2 phosphorylation, and PKCβII translocation.

GAT211 (AZ-4) is a selective and potent cannabinoid 1 receptor (CB1R) orthosteric modulator (PAM) with high affinity for cAMP and β-arrestin2.GAT211 has IOP-lowering and antipsychotic effects and can be used in the study of epilepsy.

GPR35 agonist 3 is a synthetic GPR35 agonist with an EC50 value of 1.4 μg in the β-arrestin recruitment assay.GPR35 agonist 3 is used in the study of cancer, type 2 diabetes, and cardiovascular disease.

ELA-11 (human) acetate high affinity apelin receptor agonist (Ki = 14 nM). Bioactive fragment of ELA-32. Inhibits forskolin-induced cAMP production and stimulates β-arrestin recruitment in vitro.

TC14012 acetate is a serum-stable derivative of T140 which is a selective and peptidomimetic CXCR4 antagonist with an IC50 of 19.3 nM. TC14012 is also a potent CXCR7 agonist with an EC50 of 350 nM for recruiting β-arrestin 2 to CXCR7. TC14012 has anti-cancer activity and anti-HIV activity.

DHICA (5,6-Dihydroxyindole-2-carboxylic acid) is an intermediate in melanin synthesis and a component of eumelanin, as well as acting as a moderate potency agonist of GPR35. In the U2OS cell line, DHICA demonstrates the ability to induce β-arrestin translocation signaling with an EC50 value of 23.2 μM. Additionally, it plays a significant role in promoting and protecting against DNA damage.

SCH-900875 is an orally active, brain-penetrant, and selective inhibitor of the CXCR3 receptor, demonstrating significant selectivity towards CXCR1 and CXCR2 receptors as well. By binding to CXCR3, SCH-900875 blocks the ligands CXCL9, CXCL10, and CXCL11, thereby inhibiting downstream G protein and β-arrestin signaling pathways and reducing inflammation cell migration. This compound holds potential for research into autoimmune diseases (such as rheumatoid arthritis and multiple sclerosis) and inflammatory conditions (such as psoriasis and inflammatory bowel disease).
