Overview

About MOTS-C

MOTC (also referred to as MOT-C or Melanotan-related opioid tetrapeptide compound in some research literature) is a synthetic research peptide studied for its interactions with melanocortin receptor subtypes. Research interest in this class of compounds centers on the melanocortin system's involvement in energy balance regulation, pigmentation biology, and neuromodulatory signaling pathways studied in preclinical model systems.

Peptides in the melanocortin research category have been investigated extensively in rodent models, where selective receptor subtype engagement allows researchers to dissect the individual contributions of MC1R, MC3R, MC4R, and MC5R to downstream physiological endpoints. MOTC is handled as a laboratory tool compound for receptor pharmacology studies and related mechanistic research.

As with all peptide research compounds, MOTC is supplied as a lyophilized powder for laboratory use by trained scientific personnel. Handling follows standard peptide storage and reconstitution protocols. The compound is not intended for human or veterinary administration and has no approved clinical status.

MC3R and MC4R are extensively studied in the context of hypothalamic energy regulation; researchers use selective agonist tool compounds to dissect receptor-specific contributions to food intake and energy expenditure endpoints in animal models.

04
Sexual function signaling pathways

MC4R-targeted peptides have been studied in preclinical models examining central nervous system mechanisms related to reproductive neuroendocrinology, an active area of receptor pharmacology research.

05
Anti-inflammatory pathway investigation

Melanocortin peptides engaging MC1R and MC3R have been studied for their modulation of NF-kB and cytokine production in macrophage and neutrophil assay systems, contributing to inflammation biology research.

Methodology

How It Is Studied

Melanocortin receptor-targeting peptides like MOTC are characterized using cAMP reporter assays in HEK293 cells stably expressing individual receptor subtypes. Concentration-response curves establish potency (EC50) and efficacy (Emax) parameters, and selectivity ratios across the five receptor subtypes are determined by parallel assay. Radioligand displacement studies are used to confirm receptor binding affinity.

In rodent in vivo studies, melanocortin peptides are administered intracerebroventricularly or peripherally depending on the CNS target of interest. Food intake, locomotor activity, body temperature, and body composition endpoints are monitored over defined post-administration time windows. Researchers use stereotaxic injection techniques for central delivery to specific brain nuclei.

Researchers studying pigmentation use these compounds in primary melanocyte cultures and B16 melanoma cell lines, measuring melanin content spectrophotometrically and tyrosinase enzyme activity as proximal readouts of MC1R pathway engagement.

Storage protocols

Storage & Handling

Lyophilized MOTC should be stored at -20 °C in a sealed vial protected from light and moisture. Stability under these conditions is maintained for the duration of the labeled shelf life. Upon reconstitution in sterile water or bacteriostatic saline, solutions should be stored at 4 °C and used within 7 days.

Researchers should avoid repeated freeze-thaw cycles of reconstituted peptide solutions. Aliquoting prior to first reconstitution is strongly recommended for laboratories requiring multiple experimental runs from a single vial.

FAQ

Frequently Asked Questions

What is the melanocortin system and why is it studied?+
The melanocortin system comprises five G-protein-coupled receptor subtypes (MC1R-MC5R) that respond to endogenous ligands including alpha-MSH and ACTH. It is studied for its roles in pigmentation, energy homeostasis, immune modulation, and neuroendocrine signaling.
How are melanocortin receptor subtypes distinguished in research?+
Researchers use subtype-selective synthetic agonists and antagonists in parallel assay formats, comparing potency and efficacy across cells expressing individual receptor subtypes to establish selectivity profiles for each tool compound.
What assay systems are standard for melanocortin receptor research?+
cAMP accumulation assays in recombinant receptor-expressing cell lines are the primary functional readout. HTRF and LANCE cAMP kits are commonly used for high-throughput formats. Beta-arrestin recruitment assays add information on receptor internalization and biased signaling.
Does MOTC require special handling precautions?+
As with all bioactive research peptides, MOTC should be handled by qualified laboratory personnel using appropriate personal protective equipment. Standard containment procedures for peptide research compounds apply.
Is MOTC approved for human or clinical use?+
No. MOTC is a laboratory research compound with no approved clinical status. It is supplied exclusively for scientific investigation in properly equipped research environments.
