AZ7976 (Compound 42) is a highly selective agonist for the Relaxin Family Peptide Receptor 1 (RXFP1) (pEC50 > 10.5). AZ7976 enhances RXFP1's cAMP signaling through an allosteric mechanism, thereby physiologically increasing heart rate. AZ7976 can be used in the field of cardiovascular disease research.

Description

AZ7976 (Compound 42) is a highly selective agonist for the Relaxin Family Peptide Receptor 1 (RXFP1) (pEC50 > 10.5). AZ7976 enhances RXFP1's cAMP signaling through an allosteric mechanism, thereby physiologically increasing heart rate. AZ7976 can be used in the field of cardiovascular disease research[1].

In Vitro

AZ7976 (90 min; concentration responses) does not compete with relaxin H2 for binding to RXFP1 in CHO-hRXFP1 cells, but enhances 125I-relaxin H2 binding[1].
AZ7976 inhibits ion channels and bile salt efflux transporter (BSEP) and is cytotoxic to THP1[1].

In Vivo

AZ7976 (i.v.; initial 1.5 mg/kg; i.v.drip; continuous 9.0 mg/kg) causes a significant increase in heart rate and a rise in mean arterial blood pressure in the rats.[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
