Also known as: B7 33

B7-33 is a synthetic peptide that functions by modulating the relaxin receptor, known for its involvement in vasodilation and antifibrotic effects. Interest in B7-33 started around its potential to mimic the beneficial properties of relaxin without the complex side effects. The peptide has been studied for its ability to target specific pathways related to cardiovascular health. Unlike relaxin, B7-33 is designed to selectively activate particular receptor functions, offering a more focused approach in research. Today, it is primarily studied for its effects on:

  • Cardiovascular health
  • Antifibrotic effects
  • Vasodilation
  • Receptor modulation

Secondary research interest includes its role in tissue repair and regeneration.
