As a naturally sourced cationic active peptide, melittin spray delivers highly potent biological effects centered around two core functional dimensions. Both properties stem from its distinctive molecular structure and specific action pathways, enabling it to exert distinct physiological activities. This unique trait not only highlights its superior molecular configuration but also lays a solid foundation for its further development, practical application and industrial conversion. Different from many natural active peptides that only possess a single functional property, the two major characteristics of this operate relatively independently while also featuring potential molecular correlations. They are capable of taking effect at both the cellular level and the systemic level of the human body. In the following content, we will conduct an in-depth elaboration on these two core traits from various perspectives such as molecular mechanisms, detailed action processes and prospective applications, so as to fully clarify their internal working logic and practical functional value.

Melittin price & its regulation on inflammatory mediators and antagonism to prostaglandin synthesis
The core efficacy of melittin spray in the field of phlogistic regulation is mainly reflected in the targeted inhibition of specific phlogistic mediators and the blockade of prostaglandin biosynthesis. This process involves multiple dimensions such as molecular level signal transduction regulation and cellular level secretion inhibition, and each link works together to form a complete phlogistic regulation system. The specificity and comprehensiveness of its mechanism of action make it an important research object in natural phlogistic regulatory substances.
01.The targeted regulatory mechanism of TNF - α.
TNF - α, as the core phlogistic mediator in pro-phlogistic response, its overexpression can cause disorder of the body's phlogistic response, exacerbate tissue damage and phlogistic infiltration. Mellttin can achieve targeted inhibition of TNF - α by regulating the transcriptional activity of the nuclear factor kappa B (NF - κ B) signaling pathway. Specifically, mellttin can bind to key regulatory factors in the NF - κ B signaling pathway, preventing their translocation into the nucleus, thereby downregulating the transcription and expression levels of TNF - α genes and reducing their secretion and release. This regulation is not a simple inhibitory effect, but presents precise dose-dependent regulatory characteristics.
Within an appropriate concentration range, it can specifically inhibit the overexpression of TNF - α without affecting the normal phlogistic defense response of the body. Relevant in vitro macrophage culture systems have verified that after treatment with mellttin, the secretion of TNF - α can be reduced by 40% -60%, and there is no significant interference with the normal physiological function of macrophages. In addition, melttin can also change its spatial conformation and reduce its biological activity by binding to TNF - α molecules themselves, further weakening its pro-inflammatory effect and forming a dual regulatory mechanism.
02.Inhibition and extension of IL-6 secretion.
IL-6, as another key pro-phlogistic mediator, works synergistically with TNF - α to promote the occurrence and development of phlogistic responses, and plays an important role in the sustained progression of chronic inflammation. The regulation of IL-6 by this mainly focuses on the cellular secretion level, and can target the inhibition of IL-6 secretion in phlogistic related cells such as synovial fibroblasts and macrophages. Its pathway of action is mainly achieved by inhibiting the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway.
Blocking the expression regulation of IL-6 gene, and reducing the synthesis and release of IL-6.Meanwhile, melittin spray can also inhibit the expression of IL-6 receptors, reduce the binding efficiency between IL-6 and receptors, weaken the transmission of downstream pro-phlogistic signals, and thereby alleviate IL-6 mediated phlogistic responses such as tissue edema and phlogistic cell infiltration. In chronic inflammation models, it can significantly reduce the concentration of IL-6 in local tissues, alleviate phlogistic damage, and this inhibitory effect is persistent, effectively delaying the progression of chronic inflammation.
03.Blocking the pathway of prostaglandin synthesis.
Prostaglandins, as important mediators in inflammatory reactions, rely mainly on the catalytic action of cyclooxygenase (COX) in their biosynthesis process. COX-2, as an inducible cyclooxygenase, is highly expressed under phlogistic stimulation, promoting the synthesis of prostaglandins and exacerbating inflammation and tissue pain. Mellttin can specifically antagonize the activity of COX-2 and block the biosynthesis of prostaglandins. Specifically, mellttin can bind to the active site of COX-2, inhibit its catalytic activity, reduce the conversion of arachidonic acid to prostaglandins.
And thus lower the concentration of prostaglandins in the body.In addition, mellttin can downregulate the expression level of COX-2 gene, reduce COX-2 synthesis, and block the production of prostaglandins from the source, forming a dual blocking effect of "activity inhibition+synthesis inhibition". This blocking effect is highly specific and only targets COX-2. It has no significant effect on COX-1, which is involved in regulating normal physiological functions. It can effectively inhibit phlogistic reactions while avoiding interference with the body's normal physiological metabolic processes.
04.The synergistic effect of inflammatory regulation and experimental evidence.
The inhibition of TNF - α and IL-6 by mellttin and the blockade of prostaglandin synthesis do not exist in isolation, but exhibit significant synergistic effects.
The three work together to inhibit the occurrence and development of phlogistic reactions at different stages, forming a complete phlogistic regulatory network.In vivo experiments have confirmed that malittin treatment can significantly reduce the levels of inflammatory mediators in phlogistic model animals, alleviate edema and infiltration of inflammatory tissues, and alleviate pain responses caused by inflammation. Its inflammatory regulatory effect is comparable to traditional anti-inflammatory substances, and there are no significant side effects. In addition, molecular docking experiments showed that mellttin can form stable binding with TNF - α, IL-6, and COX-2, further confirming its targeted regulation specificity and reliability, providing a solid molecular basis for its phlogistic regulatory effect.

From psychophysical perception and behavioral observation perspectives, subcutaneous injection of malittin can trigger obvious and long-lasting tonic pain in both human bodies and experimental animals. This persistent painful stimulus will further induce a variety of typical pain-related behaviors, such as limb retraction, restlessness and reduced activity, which are intuitive external manifestations of pain sensation. At the microscopic cellular level, malittin exerts complex pharmacological effects on primary nociceptor cells. It can activate these sensory nerve cells through two distinct modes of action. On one hand, malittin acts directly on the surface structures and internal components of nociceptor cells to initiate cellular excitation. On the other hand, it also works indirectly by regulating surrounding microenvironments and related signaling molecules. The combined direct and indirect effects jointly stimulate the activity of primary nociceptor cells, and then transmit pain signals step by step to form a complete pain response pathway inside the organism.
