Kisspeptin antagonist p271 can block the binding of endogenous Kisspeptin to GPR54 on pituitary somatotropes, thereby relieving the inhibition of growth hormone secretion. Kisspeptin antagonist p271 can specifically and significantly stimulate growth hormone secretion, while inhibiting luteinizing hormone without affecting prolactin or cortisol. Kisspeptin antagonist p271 can be used in the research of diseases related to insufficient growth hormone secretion .

[Nphe1]Nociceptin(1-13)NH2	Opioid Receptor	Inflammation/Immunology
[Nphe1]Nociceptin(1-13)NH2, a novel nociceptin/orphanin FQ (NC) endogenous ligand, is a selective and competitive ociceptin receptor antagonist without any residual agonist activity. [Nphe1]nociceptin(1-13)NH2 binds selectively to recombinant nociceptin receptors (pK_i=8.4) and antagonizes the inhibitory effects of nociceptin on cyclic AMP accumulation in CHO cells (pA₂=6.0). [Nphe1]Nociceptin(1-13)NH2 has the potential to act as an analgesic agent .

Nocistatin	Opioid Receptor	Neurological Disease
Nocistatin, a neuropeptide, is an endogenous ligand for the orphan opioid receptor-like receptor. Nocistatin is also a functional antagonist of neuropeptide nociceptin or orphanin FQ (Noc/OFQ). Nocistatin inhibits 5-HT release via a G_i/o proteinmediated pathway. Nocistatin blocks Nociceptin (Nociceptin)-induced allodynia and hyperalgesia .

JMV 236	Histone Methyltransferase	Neurological Disease
JMV 236 is a cholecystokinin antagonist with appetite-suppressing activity. JMV 236 affects the regulation of food intake through the interaction of the intestinal endogenous peptide PrRP and the CCK1 receptor. The administration of JMV 236 activates PrRP neurons located in the NTS, thereby enhancing its appetite-suppressing effect. JMV 236 has significant effects on areas of the central nervous system associated with food intake, especially during states of starvation .

Anti-Mouse CXCR4 Antibody (Cx4Mab-1)	CXCR	Cancer
Anti-Mouse CXCR4 Antibody is a monoclonal antibody that specifically recognizes murine CXCR4 (C-X-C chemokine receptor 4), also known as fusin or CD184. CXCR4 is a seven-transmembrane G protein–coupled receptor whose principal endogenous ligand is CXCL12 (stromal cell–derived factor-1α, SDF-1α) and is widely expressed in hematopoietic cells, endothelial cells, neurons, as well as embryonic and adult stem cells. The CXCR4–CXCL12 signaling axis activates multiple downstream pathways, including ERK1/2, Ras, p38 MAPK, PLC/MAPK, and SAPK/JNK, thereby regulating cell survival, proliferation, migration, and stemness maintenance. Aberrant overexpression of CXCR4 is closely associated with poor prognosis and metastasis in various cancers, with CXCR4-positive tumor cells preferentially home to CXCL12-rich tissues such as the liver, bone marrow, lung, and lymph nodes. Accordingly, CXCR4 and its CXCL12-related antagonists emerge as attractive targets for experimental anticancer therapy. Anti-Mouse CXCR4 Antibody is generated using a cell-based immunization and screening strategy and exhibits high affinity for both endogenous and exogenous murine CXCR4. Anti-Mouse CXCR4 Antibody can be used for thestudy of chronic lymphocytic leukemia and multiple myeloma .
