1.MECHANISM OF ACTION
Type A Allatostatin II exerts its effects by binding to specific G protein-coupled receptors (GPCRs) of the Allatostatin A receptor family. Its mechanism involves:
- Receptor Binding & Gi/o Protein Coupling: The peptide binds with high affinity to AST-ARs on target cells (endocrine cells, neurons, muscle). Receptor activation couples to inhibitory Gi/o proteins.
- Inhibition of Adenylate Cyclase: This coupling leads to the inhibition of adenylate cyclase, resulting in a decrease in intracellular cyclic AMP (cAMP) levels.
- Suppression of Juvenile Hormone Synthesis: In the corpora allata, the drop in cAMP inhibits the enzymatic pathways responsible for juvenile hormone biosynthesis. JH is critical for maintaining juvenile stages, promoting reproduction, and regulating metamorphosis.
- Myoinhibitory & Neuromodulatory Actions: In the nervous system and visceral muscle, it reduces the frequency and amplitude of contractions (e.g., in the gut) and modulates neuronal excitability, primarily through the inhibition of cAMP-dependent pathways and potential modulation of ion channels.
2.PRODUCT INDICATIONS
This product is indicated for specialized research in invertebrate biology and applied entomology. Key applications include:
- Insect Endocrinology Research: Studying the regulation of development, metamorphosis, reproduction (vitellogenesis), and diapause via control of juvenile hormone titers.
- Insect Neurobiology & Physiology: Investigating its role as an inhibitory neurotransmitter/neuromodulator in the central and stomatogastric nervous systems, and its myoinhibitory effects on the foregut and hindgut.
- Comparative Neuropeptide Evolution: Exploring the structure and function of AST-A peptides across different arthropod species.
- Biorational Pest Control Discovery: Serving as a lead compound for designing novel, species-specific insect growth regulators (IGRs) or neuropeptide analogs that disrupt critical physiological processes in pest insects.
3.CLINICAL EFFICACY OF PRODUCT
Type A Allatostatin II is not a clinical therapeutic for humans or vertebrates. Its "efficacy" is demonstrated in the context of basic science and agricultural research.
- Validated Bioactivity: It is a well-established, potent inhibitor of JH production and a functional neuromodulator in multiple insect models, with reproducible physiological effects.
- Critical Research Reagent: It is an essential tool for dissecting complex neuroendocrine networks that control insect life cycles and behavior.
- Template for Pest Management Solutions: Research utilizing this peptide provides the molecular and physiological basis for developing innovative pest control agents. Its high specificity for insect systems makes it a promising candidate for the design of environmentally friendly, target-selective insecticides or insectistatics that interfere with development and reproduction.
