Melanotan 2: Melanocortin Receptor Research

Introduction

Melanotan 2 is a synthetic melanocortin receptor agonist studied in research for melanogenesis and related pathways. As a premier peptide supplier UK, we provide this non-selective agonist active across the MC1R–MC5R receptor family.

Melanocortin Receptors

The melanocortin system comprises five receptor subtypes (MC1R–MC5R), each with distinct tissue distribution and functions:

• MC1R — expressed in skin melanocytes; drives melanogenesis (pigment production)
• MC2R — expressed in the adrenal cortex; involved in steroidogenesis
• MC3R — expressed in the central nervous system; studied in energy homeostasis
• MC4R — expressed in the hypothalamus; studied in appetite and behaviour
• MC5R — expressed in exocrine glands; studied in sebaceous gland function

Melanotan 2 is a non-selective agonist, meaning it activates all five receptor subtypes. This makes it valuable for research into the melanocortin system as a whole.

Research Applications

Melanotan 2 is studied in:

• Melanogenesis research — MC1R activation drives pigment production in skin models
• Melanocortin receptor pharmacology — binding affinity and efficacy across MC1R–MC5R
• Behavioural research — central MC3R/MC4R activity is studied in behavioural models
• Pigmentation pathway research — the melanogenesis signalling cascade

Melanotan 2 as a Research Tool

As a non-selective agonist, Melanotan 2 allows researchers who buy peptides UK to activate the entire melanocortin receptor family simultaneously. This is useful for:

• Studying the overall melanocortin system
• Comparing selective vs non-selective agonism
• Investigating cross-talk between melanocortin receptor subtypes
