Rating: 4.5 (89 reviews)

Lys-(Hyp3)-Bradykinin CAS NO.113662-39-8

Lys-(Hyp³)-Bradykinin is a naturally occurring kinin peptide and a potent bradykinin B₂ receptor agonist, originally isolated from human urine. It features a key structural modification with 4-hydroxyproline (Hyp) at position 3, which enhances its stability and receptor interaction compared to standard bradykinin. This high-purity research-grade peptide is specifically designed for scientists studying the kallikrein-kinin system, vascular biology, and inflammatory pathways in both in vitro and in vivo experimental models.

1.MECHANISM OF ACTION

The peptide exerts its effects by selectively binding to the constitutively expressed bradykinin B₂ receptor (B₂R), a G protein-coupled receptor (GPCR). This binding activates the Gq/11 signaling pathway, stimulating phospholipase C (PLC) and leading to the production of inositol trisphosphate (IP₃) and diacylglycerol (DAG). The subsequent release of intracellular calcium and activation of protein kinase C (PKC) drives downstream effects such as nitric oxide (NO) synthesis, prostaglandin release, and MAPK pathway activation, which collectively mediate vasodilation, smooth muscle contraction, and pain signaling.

2.PRODUCT INDICATIONS

Lys-(Hyp³)-Bradykinin is indicated for preclinical research applications focusing on inflammation, vascular permeability, pain mechanisms, and cardiovascular regulation. It serves as a reliable positive control in receptor binding assays and functional studies using isolated tissues (e.g., vascular rings, ileum). Researchers utilize it to model acute inflammatory responses, study endothelial dysfunction in hypertension or sepsis, and screen for novel B₂ receptor antagonists in drug discovery pipelines.

3.CLINICAL EFFICACY OF PRODUCT

In experimental models, Lys-(Hyp³)-Bradykinin demonstrates high efficacy in inducing B₂ receptor-mediated physiological responses, including potent vasodilation, increased vascular permeability leading to edema, and sensitization to pain (hyperalgesia). Studies in human fibroblasts and smooth muscle cells confirm its ability to stimulate inositol phosphate accumulation and cAMP production with potency comparable to native bradykinin. While not a therapeutic agent itself, its robust agonist activity makes it a critical tool for validating the B₂ receptor as a target in inflammatory and cardiovascular disease research.
