Melanotan I (MT-I; [Nle4,D-Phe7]-α-MSH) is an α-MSH (HY-P0252) analog, synthetic melanotropic peptide, and melanocortin receptor (MCR) agonist. Melanotan I induces skin tanning by mimicking the action of α-MSH on the melanocortin 1 receptor (MC1R) in melanocytes. As an appetite suppressant, Melanotan I impairs the ability of insulin to inhibit endogenous glucose production, suppresses leptin secretion from adipose tissue, and thereby reduces voluntary feed intake in ewes. Melanotan I can be used in research related to UV-induced skin damage, polymorphic light eruption, ruminant feeding, and sexual dysfunction.

In Vitro

Melanotan I (1.0 μM) does not enhance anchorage-independent clonogenic cell growth, a hallmark of malignancy, in freshly isolated human melanoma cell populations, with unaltered or slightly inhibited colony formation at 1.0 μM^[2].
Melanotan I inhibits proliferation of cultured human melanoma cell lines, demonstrating differentiating (melanogenic) activity^[2].
Melanotan I does not alter melanoma invasiveness in the human amniotic basement membrane model in vitro^[2].
Melanotan I stimulates cAMP production and subsequent eumelanin synthesis in cultured human melanocytes with some polymorphic MC1R variants^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Melanotan I (0.03 nmol/h; intracerebroventricular administration; continuous infusion) reduces voluntary feed intake by 50% in adult Suffolk ewes, increases plasma thyroid hormone levels in a feed intake-independent manner, impairs the inhibitory effect of insulin on endogenous glucose production in undernourished ewes, and decreases plasma leptin levels in moderately undernourished ewes^[1].
Melanotan I (10 μM; topical administration) does not induce skin papillomas in vjun transgenic mice, but causes local skin pigmentation^[2].
Melanotan I (4 mg; subcutaneous injection; single sustained-release injection) increases the eumelanin content in guinea pig skin by 2.5-fold, induces persistent pigmentation lasting up to 10 months, and shows no toxicity^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Suffolk ewes (3.5 yr old, body weight 84-96 kg, body condition score 3.3-4.0)^[1]
Dosage:

0.0003 nmol/h; 0.003 nmol/h; 0.03 nmol/h
Administration:

i.c.v.; continuous; 24-82 h
Result:

Reduced voluntary dry matter intake by 50% (from 2,108 g DM/d to ~1,054 g DM/d) and energy intake from 1.8-fold maintenance to 1.1-fold maintenance; the appetite-suppressant effect was first detected 6-24 h after infusion initiation and sustained for 72 h.
Reduced dry matter intake by ~40% (from 2,170 g to 1,293 g) and energy intake from 1.8-fold maintenance to 1.01-fold maintenance; increased plasma triiodothyronine (T3) from 1.27 ng/mL to 1.60 ng/mL and plasma thyroxine (T4) from 5.50 ng/mL to 8.31 ng/mL in an intake-independent manner, with no effect on plasma glucose, insulin, cortisol, or free fatty acids.
Increased plasma T3, tended to reduce plasma leptin, had no effect on basal plasma glucose, fatty acids, insulin, or glucose entry rate, but blunted insulin-dependent suppression of endogenous glucose production during hyperinsulinemic-euglycemic clamps at both low and high insulin infusion rates.
Reduced plasma leptin with no effect on plasma adiponectin.

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.5 mg/mL (1.52 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 2.5 mg/mL (1.52 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Working Solution

For the following dissolution methods, please prepare the working solution directly:

It is recommended to prepare fresh solutions and use them promptly within a short period of time.

The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
