Melanotan 2 Overview

Melanotan II is a synthetic cyclic heptapeptide analog of α-MSH, a naturally occurring peptide that regulates pigmentation through target receptor activation. Originally developed as a research compound for studying melanogenesis and photoprotective pathways, MT-II exhibits high affinity for its primary target receptor subtypes. Through selective binding to multiple pathway targets, it has been examined in research contexts involving pigmentation pathways, endocrine signaling, and peptide-receptor pharmacology in laboratory settings.

Dorr et al. (2004).

History

Melanotan II was synthesized in the 1990s at the University of Arizona as part of peptide signaling research aimed at developing photoprotective research compounds. Building upon earlier work with linear melanotropic peptides, researchers created this cyclized analog to improve stability and target selectivity. The peptide emerged from systematic structure-activity relationship studies examining peptide-receptor agonist dynamics.

Research Findings

Melanotan II has been investigated in peptide-receptor research and pigmentation pathway studies, with particular focus on target selectivity, signaling cascades, and downstream biological responses in controlled experimental settings. Research has explored its interactions with multiple target receptor subtypes and associated molecular mechanisms.

Key Areas of Research:

  • Receptor: Target binding, activation, selectivity

  • Pigmentation: Melanogenesis, tyrosinase, eumelanin

  • Pharmacology: Structure-activity, ligand dynamics

  • Signaling: cAMP pathways, MITF, downstream cascades

Together, these investigations provide insight into peptide-receptor biology and pigmentation pathway regulation. Through its multi-target activity, MT-II serves as a research tool for examining signaling systems, receptor-ligand interactions, and downstream molecular responses in experimental pigmentation and receptor expression models.

Each vial contains exactly what’s shown on the label. For example, a 10mg vial has exactly 10mg of lyophilized peptide. Researchers can divide it into smaller portions—like four 2.5mg measurements—but the total amount remains 10mg.

Peptides are supplied as lyophilized powder. They do not come reconstituted, and any extra supplies must be sourced separately for research applications.
In lyophilized powder form, peptides stay stable for up to 2 years. After reconstitution, it should be refrigerated and is generally stable for up to 2 months.

Products from Raw Peptides do not include usage instructions, as they are strictly for in vitro research and prohibited by law for human or animal use. Misuse or unlawful application will result in permanent denial of service.

Lyophilized peptides should be stored away from heat and light. Once reconstituted, they must be refrigerated to maintain stability and efficacy.
