What is Melanostatin DM 200mg (Topical)

Melanostatin DM 200mg (Topical) is a synthetic peptide designed as a potent and selective antagonist at the melanocortin-1 receptor (MC1R). Also known as a melanogenesis inhibitor peptide, Melanostatin DM is structurally related to α-melanocyte-stimulating hormone (α-MSH) but with critical amino acid modifications that convert the peptide from an agonist to an antagonist.

The “DM” designation indicates the presence of D-amino acid substitutions (typically D-Tyr, D-Phe, and/or D-Trp) that confer enhanced stability. Unlike natural L-peptides which are rapidly degraded by proteases (half-life minutes to hours), Melanostatin DM incorporates D-amino acids at key positions to resist enzymatic degradation. Unlike α-MSH which activates MC1R and stimulates melanin production, Melanostatin DM binds to the same receptor without activating the downstream cAMP/PKA signaling cascade, effectively functioning as a competitive antagonist. The topical formulation is specifically designed for dermal administration in controlled laboratory settings.

Researchers purchase Melanostatin DM 200mg (Topical) for studies involving melanocortin receptor pharmacology, melanogenesis inhibition, pigmentation pathway elucidation, melanocyte biology, and peptide stability research. This compound is strictly supplied as a lyophilized powder for reconstitution and is for research purposes only.

Product Specifications Table

How It Works 

Melanostatin DM functions as a potent and stable competitive antagonist at the melanocortin-1 receptor (MC1R), a G-protein coupled receptor (GPCR) primarily expressed on melanocytes. The “DM” designation indicates the presence of multiple D-amino acid substitutions that enhance both stability and receptor binding. The mechanism of action involves four key stages:

1. Enhanced Stability Through D-Amino Acid Substitutions:

Unlike natural L-peptides which are rapidly degraded by proteases (half-life minutes to hours), Melanostatin DM incorporates D-amino acids at key positions (typically D-Tyr, D-Phe, D-Trp). These D-amino acid substitutions provide significant research advantages:

The D-amino acid substitutions:

• Resist proteolytic degradation: Proteases are stereospecific for L-amino acids, making D-peptides resistant to cleavage.

• Extend research utility: Half-life in tissue culture extends from hours to days, enabling longer-term studies.

• Maintain or enhance binding affinity: D-amino acid substitutions at specific positions can enhance rather than reduce MC1R binding.

• Reduce aggregation: D-peptides often show reduced aggregation compared to L-peptide analogs.

2. High-Affinity Competitive Receptor Binding:

Melanostatin DM binds to the same orthosteric binding site on MC1R as endogenous α-MSH. The D-amino acid substitutions create a more constrained conformation that actually enhances binding affinity (Ki typically 10-100x lower than Nonapeptide-1). By occupying the receptor without activating it, Melanostatin DM prevents α-MSH from binding and initiating the signaling cascade.

The tetrapeptide core (Tyr-Phe-Arg-Trp) retains the critical recognition motif, while acetylation at the N-terminus and amidation at the C-terminus further enhance stability and binding. The D-configuration at positions 1, 2, and 4 locks the peptide into a bioactive conformation that optimally fits the MC1R binding pocket.

3. Potent Inhibition of cAMP/PKA Signaling:

When α-MSH binds to MC1R, the receptor activates the Gs protein, leading to:

• Activation of adenylyl cyclase

• Increased intracellular cyclic AMP (cAMP) production

• Activation of protein kinase A (PKA)

• Phosphorylation of CREB (cAMP response element-binding protein)

• Upregulation of microphthalmia-associated transcription factor (MITF)

Melanostatin DM binding blocks this cascade at the first step with higher potency than Nonapeptide-1, preventing cAMP accumulation and downstream MITF activation. In functional assays, Melanostatin DM typically exhibits IC₅₀ values in the low micromolar to nanomolar range for inhibition of α-MSH-stimulated cAMP production.

4. Downstream Effects on Melanogenesis:

The inhibition of MC1R signaling leads to:

• Reduced MITF expression: MITF is the master transcription factor for melanocyte function.

• Decreased tyrosinase (TYR) expression: Tyrosinase is the rate-limiting enzyme in melanin synthesis.

• Reduced TYRP1 and TYRP2/DCT expression: These accessory enzymes influence melanin type and quantity.

• Decreased melanin production: Both eumelanin (brown/black) and pheomelanin (red/yellow) synthesis are reduced.

• Reduced melanocyte dendricity: MC1R signaling influences melanocyte morphology and melanosome transfer.

Research Advantages Over Nonapeptide-1:

Researchers order Melanostatin DM online USA to leverage these enhanced properties for melanocortin receptor pharmacology and pigmentation research.

📦 Storage Instructions 

Proper storage of Melanostatin DM 200mg (Topical) ensures maximum stability for your melanogenesis research:

1. Store at -20°C for long-term stability:

Unopened vials remain stable for 24 months in a non-frost-free laboratory freezer. Do NOT store in a self-defrosting (auto-defrost) freezer as temperature fluctuations during defrost cycles (typically every 6-12 hours) cause peptide aggregation. While D-amino acid peptides are more stable than L-peptides, they are still susceptible to aggregation upon thermal cycling.

2. Refrigerate after reconstitution (2–8°C):

Once dissolved in bacteriostatic water, sterile PBS, or cell culture media, store at 2-8°C (standard laboratory refrigerator). Use within 14 days for bacteriostatic water formulations or 21 days if preservative-containing vehicles are used. Do NOT freeze reconstituted solutions as ice crystal formation can still damage the peptide structure despite D-amino acid stabilization.

3. Avoid repeated freeze-thaw cycles:

Although more stable than L-peptides, Melanostatin DM is still susceptible to aggregation upon repeated freeze-thaw. Aliquot reconstituted peptide into single-use portions (e.g., 50-100 µL in sterile PCR tubes) before freezing if long-term storage after reconstitution is necessary. Each aliquot should undergo no more than ONE freeze-thaw cycle.

4. Protect from light and moisture:

Store original lyophilized vials in the provided amber container or foil-wrapped box. Melanostatin DM contains aromatic residues (Tyr, Phe, Trp) that are photosensitive – prolonged light exposure (especially UV) causes oxidative degradation. Use amber glass vials for working solutions.

5. Maintain sterile conditions:

Always use a sterile syringe, 0.22 µm filter, and laminar flow hood when piercing the septum. Contamination leads to endotoxin buildup (>10 EU/mg) which activates TLR4 pathways and confounds melanocyte signaling studies.

6. Desiccate lyophilized powder:

Store unopened vials with the provided desiccant pack. Open vials only in low-humidity environments (<30% RH) to prevent moisture absorption, which causes peptide aggregation and reduced receptor binding activity.

Stability timeline:

• Lyophilized at -20°C: 24 months (≥98% purity)

• Lyophilized at 2-8°C: 8 months (≥95% purity – enhanced due to D-amino acids)

• Lyophilized at room temperature: 21 days (≥90% purity)

• Reconstituted at 2-8°C: 14-21 days (≥90% purity)

• Reconstituted at room temperature: 12-24 hours (enhanced stability over L-peptides)

For melanocyte culture studies: Prepare fresh working solutions from lyophilized aliquots every 14 days for optimal MC1R antagonist activity. The D-amino acid substitutions provide significantly longer stability than Nonapeptide-1, enabling longer-term studies without media changes affecting peptide concentration.

Failure to follow these guidelines may result in peptide degradation (oxidation of aromatic residues or aggregation), skewing your receptor binding data.

🧪 How It Is Used 

Reconstitution Protocol for In Vitro Studies

1. Centrifuge the sealed vial:

• Centrifuge at 3,000 RPM for 2 minutes to pull lyophilized powder to the bottom. This prevents loss when opening and ensures complete recovery of the 200mg dose.

2. Prepare sterile vehicle:

• For cell culture (melanocyte studies): Use sterile, endotoxin-free PBS or serum-free melanocyte growth medium.

• For ex-vivo skin research: Reconstitute in bacteriostatic water then dilute in hydrogel or cream base.

• For stock solutions (high concentration): Use 10-20% DMSO for maximum solubility (30-40 mg/mL achievable).

3. Add vehicle to achieve desired stock concentration:

• Standard stock for cell culture: 10 mg/mL (add 20 mL vehicle to 200mg vial)

• Working solution: Dilute stock 1:100 to 1:1000 in culture media (final 10-100 µg/mL or 10-100 µM) – note that lower concentrations (1-10 µM) may be effective due to higher potency.

4. Swirl gently:
Do NOT vortex or shake vigorously as this causes foaming and denaturation of the peptide structure.

5. Allow 3-5 minutes for complete dissolution:
Solution should be clear and colorless. Any turbidity or precipitation indicates aggregation or contamination.

🔗 Peptide Stacking / Combinations 

Advanced researchers often combine Melanostatin DM 200mg (Topical) with complementary peptides and research compounds to investigate synergistic effects on melanocortin receptor signaling and pigmentation regulation:

1. Melanostatin DM + α-MSH (endogenous agonist)

• Why: This is the classic antagonist-agonist combination for MC1R pharmacology studies, but with a higher potency antagonist. α-MSH activates MC1R and stimulates melanogenesis; Melanostatin DM competitively inhibits this activation with higher potency than Nonapeptide-1. Co-application allows researchers to study receptor occupancy, Schild analysis for antagonist potency (pA2 determination), and comparative pharmacology.

• Research interest: MC1R structure-activity relationships – comparing antagonist potency across different peptide analogs.

• Typical ratio: Melanostatin DM at 0.1-10 µM, α-MSH at 1-100 nM (10-1000x antagonist excess).

• Expected outcome: Rightward shift of α-MSH concentration-response curve without reduction in maximal response (competitive antagonism).

2. Melanostatin DM + Nonapeptide-1 (potency comparison)

• Why: Both are MC1R antagonists but with different potencies and stabilities. Comparing their effects allows researchers to understand structure-activity relationships and the contribution of D-amino acid substitutions to receptor binding and biological activity.

• Research interest: SAR studies – understanding which amino acid substitutions confer higher potency and stability.

• Typical ratio: Equimolar concentrations (0.1-50 µM) for comparative concentration-response curves.

3. Melanostatin DM + Melanotan II (MT-II)

• Why: Melanotan II is a potent, non-selective MC1R and MC4R agonist. Melanostatin DM is selective for MC1R. Comparing the effects of Melanostatin DM on MT-II vs α-MSH responses allows researchers to dissect receptor selectivity and investigate MC4R-independent effects on melanocytes.

• Research interest: Receptor selectivity studies – understanding which effects are MC1R-specific versus mediated by other MC receptors.

• Typical ratio: Melanostatin DM 0.1-10 µM, MT-II 1-100 nM.

4. Melanostatin DM + B16-F10 cell line (melanoma model)

• Why: B16-F10 mouse melanoma cells are a standard model for melanogenesis research. Melanostatin DM treatment in these cells allows investigation of MC1R antagonist effects on melanoma cell biology with higher potency and longer duration than Nonapeptide-1.

• Research interest: Melanoma biology – understanding the role of MC1R signaling in melanoma cell behavior, proliferation, and differentiation.

• Typical ratio: Melanostatin DM 0.1-25 µM in culture media for 48-72 hours.

5. Melanostatin DM + UVB irradiation (ex-vivo skin model)

• Why: UVB radiation is the physiological stimulus for melanogenesis (via α-MSH release from keratinocytes). Melanostatin DM can be applied to UVB-exposed skin explants to study MC1R antagonism in a more physiologically relevant model where endogenous α-MSH is the agonist. The enhanced stability of Melanostatin DM allows for longer-term studies (7-14 days) without peptide degradation.

• Research interest: Photo-pigmentation research – studying MC1R’s role in UV-induced pigmentation with a more stable antagonist.

• Typical ratio: UVB 50-200 mJ/cm² (single dose), Melanostatin DM 1-50 µM topical application 1-2 hours post-UVB.

6. Melanostatin DM + Kojic Acid (non-peptide comparator)

• Why: Kojic acid is a tyrosinase inhibitor that acts downstream of MC1R (direct enzyme inhibition). Melanostatin DM acts upstream at the receptor level. Comparing these two mechanisms allows investigation of pathway-specific effects on melanocyte biology and potential synergy.

• Research interest: Mechanism of action studies – distinguishing between receptor-level antagonism and direct enzyme inhibition.

• Typical ratio: Melanostatin DM 0.1-25 µM, Kojic acid 10-100 µM for comparative studies.

7. Melanostatin DM + Agouti Signaling Protein (ASIP)

• Why: ASIP is an endogenous antagonist of MC1R that shifts melanin production from eumelanin to pheomelanin. Melanostatin DM is a synthetic competitive antagonist. Comparing these allows investigation of different antagonism mechanisms (competitive vs allosteric/inverse agonism) and their effects on downstream signaling bias.

• Research interest: Melanocortin receptor pharmacology – understanding different modes of antagonism.

• Typical ratio: Melanostatin DM 0.1-10 µM, ASIP 1-100 nM.

8. Melanostatin DM + Protease (stability validation)

• Why: Treat Melanostatin DM with trypsin, proteinase K, or other proteases to demonstrate enhanced stability compared to L-peptide analogs (e.g., Nonapeptide-1). This is a valuable control for researchers studying peptide stability in tissue culture conditions.

• Research interest: Peptide stability studies – quantifying resistance to enzymatic degradation.

• Typical ratio: 10-100 µg/mL peptide with 0.1-1 µg/mL protease, time course 0-24 hours.

Is your Melanostatin DM lab tested?

Absolutely. Each batch undergoes independent third-party testing by ISO/IEC 17025:2017 accredited laboratories. Testing includes:

• HPLC-MS: Minimum 99% purity, full chromatogram

• Chiral HPLC: D-amino acid confirmation (≥98% chiral purity) – essential for activity validation

• Amino Acid Analysis: Sequence confirmation

• Endotoxin testing: LAL assay, <1.0 EU/mg

• Residual solvent analysis: Meets ICH Q3C guidelines

• Heavy metals: ICP-MS, <20 ppm

• Mass confirmation: ESI-MS

You can view the Certificate of Analysis (CoA) by scanning the QR code on your vial’s box or entering the batch number on our “Product Verification” page.

How is Melanostatin DM stored for long-term stability?

Long-term storage (lyophilized powder): Store at -20°C (±5°C) in a non-frost-free laboratory freezer. Do NOT use a self-defrosting (auto-defrost) freezer as temperature fluctuations cause peptide aggregation. Unopened vials are stable for 24 months. Note that D-amino acid peptides are more stable than L-peptides but still require proper storage.

After reconstitution: Store at 2-8°C (refrigerate). Use within 14 days if reconstituted in bacteriostatic water or sterile PBS. Use within 21 days if reconstituted with preservative-containing vehicles. Do NOT freeze reconstituted solutions – ice crystals can damage the peptide structure despite D-amino acid stabilization.

Handling tips: Allow frozen vials to come to room temperature (15 minutes) before opening. Aliquot reconstituted solutions for single-use portions to avoid repeated freeze-thaw cycles.

How is Melanostatin DM used in research?

Reconstitution protocol:

1. Centrifuge sealed vial at 3,000 RPM for 2 minutes

2. Under laminar flow hood, sterilize septum with 70% isopropyl alcohol

3. Add 20 mL sterile PBS or bacteriostatic water for 10 mg/mL stock

4. Swirl gently – do NOT vortex

5. Allow 3-5 minutes for complete dissolution

In vitro applications (melanocyte culture):

• Cell types: Primary human melanocytes, B16-F10 cells

• Concentration: 0.1-50 µM (higher potency than Nonapeptide-1, start with 1-10 µM)

• Treatment duration: 24-72 hours for gene expression; 5-14 days for melanin studies

• Positive control: α-MSH (10-100 nM) for MC1R activation

• Antagonist validation: Co-apply α-MSH + Melanostatin DM

Receptor binding assays:

• Radioligand: [¹²⁵I]-NDP-α-MSH

• Membranes: CHO-hMC1R or B16-F10

• Competition binding: 1 pM – 100 µM

Stability comparison: For protease resistance studies, compare with Nonapeptide-1 or other L-peptide analogs by incubating with trypsin (0.1-1 µg/mL) for 0-24 hours at 37°C and analyzing by HPLC-MS.
