Melanin Concentrating Hormone, salmon acetate (MCH (salmon)) is a 19 amino acid cyclic peptide, is largely expressed in the hypothalamus.

Melanin Concentrating Hormone, salmon TFA (MCH (salmon) TFA) is a 19-amino-acid neuropeptide discovered in teleost fish's pituitary gland, involved in controlling food intake, energy balance, sleep states, and cardiovascular functions. It acts as a ligand for the orphan G protein-coupled receptors SLC-1/GPR24 and MCHR2.

Melanin Concentrating Hormone (MCH), a 19 amino acid cyclic peptide, is largely expressed in the hypothalamus. Melanin Concentrating Hormone is implicated in the control of general arousal and goal-orientated behaviours in mammals, and appears to be a key

Nonapeptide-1 (Melanostatine™ 5) can inhibit the synthesis of melanin, which makes it of interest for treating certain skin conditions.

MCH(human, mouse, rat) is a potent endogenous agonist at melanin-concentration hormone (MCH) receptors (IC50 values are 0.3 and 1.5 nM and EC50 values are 3.9 and 0.1 nM at MCH1 and MCH2 receptors respectively). Increases food intake in vivo.

Potent melanin-concentrating hormone (MCH) receptor agonist (EC50 values are 17 and 54 nM at MCH1 and MCH2 receptors respectively). Displays some selectivity towards MCH1 over MCH2 (Ki values are 0.16 and 34 nM respectively).

Decapeptide-12, a competitive inhibitor of mushroom tyrosinase with an IC50 of 40 µM and a Kd of 61.1 μM for the C-terminal residue of tyrosinase, is a small oligopeptide that reduces melanin content in melanocytes by interacting with tyrosinase and increasing transcription of SIRT. It is utilized in researching melanogenesis, senescence, and inflammation [1] [2] [3].

Nonapeptide-1 (Melanostatine-5) acetate salt, a peptide hormone, functions as a selective and competitive antagonist of the melanocortin 1 receptor (MC1R) with a binding affinity (K i) of 40 nM. It effectively inhibits α-MSH-induced increases in intracellular cyclic AMP (cAMP) and melanosome dispersion in melanocytes, showcasing inhibitory concentrations (IC 50) of 2.5 nM and 11 nM, respectively. By inhibiting melanin synthesis, Nonapeptide-1 acetate salt finds application in research related to skin pigmentation, adrenal gland steroid production regulation, and skin cancer [1] [2] [3].

HMCH-1R Antagonist 1 (Compound 30) serves as an effective and selective antagonist for the human melanin-concentrating hormone receptor 1 (hMCHR1), exhibiting a K_B value of 3.6 nM. It possesses the ability to bind to hMCHR1 and hMCHR2, with IC_50 values of 65 nM and 49 nM, respectively. This compound is applicable in metabolic research [1].

MIF-1 TFA (Melanostatin), an intrinsic brain peptide, serves as a powerful allosteric modulator of the dopamine receptor. It plays a crucial role in regulating melanin production and modifies the analgesic efficacy by inhibiting the opioid receptor's effects. Significantly, MIF-1 TFA can cross the blood-brain barrier (BBB) directly, facilitating its access from the bloodstream to the central nervous system (CNS) [1] [2] [3].

Tetrapeptide, an α-MSH analogue, stimulates melanin production and mitigates DNA damage by attenuating reactive oxidative species generation and augmenting DNA photoproduct repair [1].

Melanotan I is a non-specific melanocortin receptor (MCR) agonist, an α-melanocyte-stimulating hormone (α-MSH) analog, which is injected subcutaneously to increase the amount of melanin in the skin Melanotan I is used as an adjunct to tanning Melanotan I has been used for the prevention of sunlight-induced skin cancers Melanotan I has been used in the study of melanoma and for male erectile dysfunction Melanotan I may be used to prevent sun-induced skin cancer and may be used to study melanoma and male erectile dysfunction.
