Mechanism of Action

It selectively activates the RXFP1 receptor, triggering anti-fibrotic signaling without unwanted vasodilatory effects.

Clinical Research

Cited studies

  1. 1Relaxin-2 and its mimetic B7-33 reduce cardiac fibrosis and inflammation
  2. 2B7-33, a functionally selective relaxin receptor agonist, reduces fibrosis without hemodynamic side effects
