1.MECHANISM OF ACTION

Neurokinin A (4-10) is a biologically active fragment of the endogenous neuropeptide Neurokinin A, functioning as a highly selective agonist of the neurokinin 2 receptor (NK2R), a G-protein coupled receptor (GPCR) widely expressed in smooth muscle tissues, central nervous system (CNS), and immune cells. Upon binding to NK2R, it activates intracellular signaling pathways via Gq/11 proteins, triggering the hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2) to generate inositol trisphosphate (IP3) and diacylglycerol (DAG). This cascade leads to increased intracellular calcium levels, which induces smooth muscle contraction (especially in the gastrointestinal, respiratory, and urogenital tracts). Additionally, it modulates pain signaling pathways in the CNS by interacting with sensory neurons, stimulates the release of other neuropeptides, and regulates immune cell activation, contributing to neuro-inflammatory responses.

2.PRODUCT INDICATIONS

Investigating the role of NK2R signaling in smooth muscle contraction and motility

Studying pain transmission, neuro-inflammatory responses, and neuropeptide network regulation in the CNS

Evaluating NK2R antagonist/agonist drug candidates for treating respiratory diseases (e.g., asthma, chronic obstructive pulmonary disease) and gastrointestinal disorders (e.g., irritable bowel syndrome)

Developing in vitro assays for NK2R ligand screening and receptor-ligand interaction studies

3.CLINICAL EFFICACY OF PRODUCT

In isolated smooth muscle preparations (e.g., guinea pig ileum, human bronchial tissue), it reliably induces concentration-dependent contraction, serving as a gold standard for evaluating NK2R antagonist potency

In murine models of asthma, it exacerbates airway hyperresponsiveness and inflammation, mimicking pathological conditions to test anti-asthmatic drug efficacy

In pain models, it enhances nociceptive signaling, enabling the screening of analgesic compounds targeting the neurokinin system
