Lys-(Des-Arg9,Leu8)-Bradykinin CAS NO.71800-37-8
<p>Lys-(Des-Arg⁹,Leu⁸)-Bradykinin is a synthetic 8-amino acid bradykinin analog designed as a selective agonist for the bradykinin B₁ receptor. It features a lysine extension at the N-terminus, replacement of the 8th proline with leucine, and deletion of the C-terminal arginine. These modifications shift its receptor selectivity from the constitutive B₂ receptor to the inducible B₁ receptor, making it a key research…

1.MECHANISM OF ACTION
The peptide acts as a potent and selective agonist for the G protein-coupled bradykinin B₁ receptor. Upon binding, it activates Gq/11-mediated signaling, leading to phospholipase C activation, IP₃ production, and intracellular calcium mobilization. This cascade stimulates MAP kinase pathways (ERK1/2, p38) and NF-κB, promoting the expression of pro-inflammatory cytokines (IL-1β, TNF-α) and adhesion molecules. The B₁ receptor is typically absent in healthy tissues but upregulated during inflammation, making this analog particularly useful for studying pathological conditions involving sustained kinin signaling.
2.PRODUCT INDICATIONS
This product is indicated for research focusing on chronic inflammatory diseases, neuropathic pain, sepsis, and diabetic complications where B₁ receptor expression is elevated. It is used to investigate the role of B₁R in persistent hyperalgesia, vascular remodeling, and endothelial dysfunction. Researchers employ it in cell-based assays, isolated tissue preparations, and animal models of chronic inflammation to screen B₁ receptor antagonists and to validate the therapeutic potential of targeting this receptor in conditions like rheumatoid arthritis and neuroinflammation.
3.CLINICAL EFFICACY OF PRODUCT
In preclinical models, Lys-(Des-Arg⁹,Leu⁸)-Bradykinin demonstrates high efficacy in inducing B₁ receptor-mediated hyperalgesia, vascular leakage, and cytokine release. Studies show it exacerbates inflammatory responses in models of adjuvant-induced arthritis and diabetic neuropathy, while B₁ antagonists effectively block its effects. Although not used clinically, its selective agonist profile has been instrumental in validating B₁R as a therapeutic target, supporting the development of clinical-stage B₁ antagonists for chronic pain and inflammatory disorders.
