Product detail
B7-33 Peptide | RXFP1-Selective Agonist | Anti-Fibrotic Research Agent
CAS No.: 1818415-56-3
Sequence: H-Val-Ile-Lys-Leu-Ser-Gly-Arg-Glu-Leu-Val-Arg-Ala-Gln-Ile-Ala-Ile-Ser-Gly-Met-Ser-Thr-Trp-Ser-Lys-Arg-Ser-Leu-OH
Molecular Formula: C₁₃₁H₂₂₈N₄₀O₃₇S
Molecular Weight: 2986.5 g/mol
Overview
B7-33 is a synthetic, single-chain peptide mimetic derived from the B-chain of human relaxin-2 (H2-relaxin). As a functionally selective agonist of the relaxin family peptide receptor 1 (RXFP1), it activates specific signaling pathways without stimulating cAMP production, serving as a targeted tool for studying fibrosis, cardiovascular repair, and inflammatory regulation.
Mechanism of Action
-
RXFP1-Specific Binding: B7-33 selectively engages RXFP1, triggering extracellular signal-regulated kinase (ERK1/2) activation while avoiding cAMP cascades and associated risks.
-
Anti-Fibrotic Action: Upregulates matrix metalloproteinase-2 (MMP-2) to promote collagen degradation and inhibit pathological scarring in cardiac, pulmonary, and renal systems.
-
Vasoprotection: Enhances endothelial-dependent vasodilation in mesenteric arteries through targeted pathway modulation.
