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.

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).
