[D-Phe7]-Bradykinin CAS NO.97825-00-8

[D-Phe⁷]-Bradykinin is a synthetic 9-amino acid bradykinin analog with a key D-phenylalanine substitution at position 7. This modification converts it from a full agonist into a partial agonist/antagonist at the B₂ bradykinin receptor (B₂R), offering unique utility for dissecting kinin signaling pathways. It is widely used in cardiovascular, inflammation, and pain research to study receptor specificity, competitive inhibition, and structure-activity relationships (SAR) in the kallikrein-kinin system

1.MECHANISM OF ACTION

The peptide binds to the B₂ receptor but, due to the D-Phe⁷ substitution, induces a suboptimal conformational change that reduces Gq/11 coupling efficiency. It acts as a competitive partial agonist: at low concentrations or in naive tissues, it may weakly stimulate phospholipase C (PLC), IP₃, and calcium release, mimicking bradykinin's vasodilatory and pro-inflammatory effects. At higher concentrations or in pre-stimulated systems, it occupies receptors without full activation, effectively blocking endogenous bradykinin and attenuating downstream nitric oxide (NO) and prostaglandin production

2.PRODUCT INDICATIONS

This analog is indicated for research requiring modulation rather than full activation of the kinin system. It is used to: (1) study B₂ receptor desensitization and trafficking; (2) probe the role of kinins in hypertension, septic shock, and angioedema through partial blockade; (3) serve as a precursor scaffold for developing more potent antagonists (e.g., icatibant analogs); and (4) investigate tissue-specific receptor subtypes in smooth muscle and neuronal preparations

3.CLINICAL EFFICACY OF PRODUCT

In preclinical models, [D-Phe⁷]-Bradykinin demonstrates graded efficacy depending on the system: it can elicit weak vasodilation or bronchoconstriction but effectively suppresses bradykinin-induced hypotension and plasma extravasation when administered as a pretreatment. Its partial agonist profile helps researchers quantify receptor reserve and allosteric modulation, providing critical data for developing clinical-grade B₂ antagonists for hereditary angioedema and inflammatory pain
