TIP39, a neuropeptide and an agonist for the parathyroid hormone receptor type 2 (PTH2R), effectively increases cAMP levels in COS-7 cells featuring recombinant PTH2R from humans or rats (EC50s = 0.5 and 0.8 nM, respectively), as well as in F-11 cells that naturally express PTH2R (EC50 = 1.15 nM). Furthermore, TIP39 at 1 nM halts the cell cycle at the G0/G1 phase and reduces Sox9 expression, a crucial regulator of cartilage differentiation, in CFK2 rat chondrocytes. Additionally, administering 100 pmol/animal of TIP39 reduces the immobility period in the forced swim test in mice, indicating a potential antidepressant effect.

Neurokinin B TFA, a member of the tachykinin family, binds to a series of GPCRs, including neurokinin receptors 1 (NK1R), NK2R, and NK3R, to modulate their biological effects.

Orexin B, rat, mouse (Rat orexin B) TFA, an endogenous agonist for orexin receptors, binds to and activates the orphan G protein-coupled receptors OX1-R and OX2-R, playing a crucial role in stimulating food intake, increasing energy expenditure, and regulating sleep-wake cycles [1] [2] [3].

Polymyxin B nonapeptide TFA (catalog number T64687) is a valuable organic compound for life sciences research.

Neuropeptide Y (NPY), a neuropeptide, plays roles in regulating appetite, vasoconstriction, cardiac contractility, and intestinal secretion, acting as an agonist for NPY receptors Y1, Y2, and Y5. Expressed ubiquitously, NPY modulates cellular responses by selectively inhibiting forskolin-induced cAMP accumulation in L-M(TK-) cells expressing rat Y1 or Y2 and in HEK293 cells expressing rat Y5, more so than in cells expressing rat Y4 receptors (EC50s = 0.15, 2.7, 0.66, and >1,000 nM, respectively). Additionally, it elevates perfusion pressure in isolated guinea pig hearts (EC30 = 1.3 nM) and, when administered intracerebroventricularly at 300 pmol/animal, it notably increases food intake in rats.

CRF, bovine (TFA) is a potent agonist of CRF receptor, and displaces [125I-Tyr]ovine CRF with a Ki of 3.52 nM.CRF, bovine is a potent agonist of CRF receptor, and displaces [125I-Tyr]ovine CRF with a Ki of 3.52 nM[1]. CRF shows pEC50s of 11.16, 8.53 and 8

Dynorphin B (1-13) TFA, an agonist of the opioid κ-receptor.

Bovine Myeloid Antimicrobial Peptide (BMAP) 28, a synthetic peptide derived from bovine cathelicidin-5 (amino acids 132-158), exhibits antimicrobial activity against E. coli, S. aureus, MRSA, S. epidermidis, and the fungus C. albicans, with minimum inhibitory concentrations (MICs) of 2, 2, 4, 1, and 8 µM respectively. At a concentration of 200 nM, BMAP 28 permeabilizes the inner membrane of E. coli, and at 5 µM, it inhibits herpes simplex virus 1 (HSV-1) replication in Vero 76 cells. Furthermore, at 30 µM, it causes hemolysis in human erythrocytes and cytotoxicity in human neutrophils. In vivo, a dose of 0.8 mg/kg enhances survival in mice infected with E. coli or MRSA, but not P. aeruginosa.

Proadrenomedullin N-terminal 12 peptide (PAMP-12), an endogenous fragment originating from the adrenal medulla and spanning amino acids 9-20 of human PAMP-20, plays a role in causing hypotension. It functions as an agonist for the MAS-related G protein-coupled receptor family member X2 (MRGPRX2), inhibiting forskolin-stimulated cAMP accumulation in CHO cells expressing human MRGPRX2 (EC50 = 57.2 nM) and selectively prompting calcium mobilization in these cells (EC50 = 41 nM), but not in cells expressing MRGPRX1, MRGPRX3, or MRGPRX4 at 1 µM. As an antagonist of nicotinic acetylcholine receptors (nAChRs), PAMP-12 obstructs carbachol-triggered catecholamine release and the influx of calcium and sodium (IC50s = 1.3, 0.39, and 0.87 µM, respectively) in primary bovine adrenal chromaffin cells, with no effect on histamine-induced responses (IC50s = >1 µM for all). Additionally, it decreases mean arterial blood pressure in normotensive rats at doses ranging from 10 to 50 nmol/kg.
