5-amino-1mq 5MG

5-Amino-1MQ (5-amino-1-methylquinolinium) is a membrane-permeable analogue of methylquinolinium that has become a widely studied NNMT inhibitor in metabolic and cellular energetics research. NNMT is expressed in multiple tissues but is particularly abundant in adipose and hepatic cells, where it participates in nicotinamide utilization and impacts NAD⁺-related pathways.

Because NNMT activity can influence intracellular NAD⁺ levels and downstream regulators such as sirtuin 1 (SIRT1), 5-Amino-1MQ is often selected as a tool compound to probe:

• NNMT’s role in adipocyte size and fat storage
• NAD⁺-dependent metabolic pathways and mitochondrial function
• Sirtuin-linked gene regulation and cellular stress responses

5-Amino-1MQ offers a standardized format for labs that require reproducible dosing within in vitro, ex vivo, or non-clinical in vivo experimental frameworks, in accordance with institutional and regulatory guidelines.

Researchers employ 5-Amino-1MQ in a variety of metabolic and cellular biology models. The following themes summarize key areas of ongoing investigation:

NNMT, NAD⁺, and Energy Metabolism

NNMT catalyzes the methylation of nicotinamide, diverting potential NAD⁺ precursors into alternative metabolites. In multiple preclinical studies, elevated NNMT activity has been associated with altered NAD⁺ pools and changes in cellular energy efficiency, particularly in adipose tissue and liver.

By inhibiting NNMT, 5-Amino-1MQ has been used to study:

• How modulation of NNMT affects NAD⁺ levels in cell lines and animal models
• The downstream impact on mitochondrial respiration and oxidative metabolism
• The relationship between NNMT activity and regulators such as SIRT1, which is widely examined in the context of cellular aging, metabolic control, and stress responses

These investigations are mechanistic in nature and are designed to clarify how NNMT fits into broader metabolic and epigenetic networks.

Adipocyte Biology and Body Mass Models

In rodent models, NNMT expression in adipose tissue has been linked to adipocyte size, lipid accumulation, and changes in energy expenditure. Experimental NNMT inhibition with compounds such as 5-Amino-1MQ has been reported to correlate with:

• Reduced fat cell size and changes in fat mass in diet-induced models
• Shifts in metabolic efficiency and energy utilization
• Altered expression of glucose transporters (including GLUT4) in skeletal muscle and fat tissue

Some studies have observed notable changes in body mass and adipose tissue over relatively short experimental periods without modifications in food intake. These findings are specific to controlled animal models and are used to better understand how NNMT and related pathways influence energy storage and utilization, not to support clinical or therapeutic conclusions.

Muscle Function and Regenerative Research

NNMT is also expressed in skeletal muscle, and 5-Amino-1MQ has been utilized to examine NNMT’s role in muscle energetics and repair. Preclinical investigations in aged animal models have reported that NNMT inhibition may:

• Influence activation of muscle-resident stem cells following injury
• Alter myofiber cross-sectional area and contractile properties
• Interact with NAD⁺-dependent mechanisms implicated in mitochondrial quality and tissue resilience

These findings support the use of 5-Amino-1MQ as a research tool for studying muscle regeneration, sarcopenia models, and age-associated changes in muscle physiology. Any implications for human health remain speculative and unverified.

Neuro-Energetic Pathways and Cognition Research

NAD⁺ is central to neuronal energy metabolism and synaptic function. While 5-Amino-1MQ itself has not been extensively characterized in human neurocognitive contexts, its interaction with NNMT and effects on NAD⁺ pathways have generated interest in:

• Brain energy homeostasis and mitochondrial support in preclinical models
• Neuromuscular junction signaling and synaptic transmission
• How altered NAD⁺ metabolism may relate to age-related cognitive decline in experimental systems

Current research in this area remains exploratory, and 5-Amino-1MQ is used strictly as an investigative tool within laboratory models.

NNMT Expression in Oncology Research

Increased NNMT expression has been documented in several tumor types in preclinical and ex vivo studies, including gastric, pancreatic, renal, and bladder cancer models. Because NNMT is involved in methylation and metabolic control, 5-Amino-1MQ is of interest in:

• Characterizing NNMT as a potential biomarker of tumor metabolism
• Studying how NNMT modulation may influence cancer cell proliferation, redox balance, and methyl-donor utilization
• Evaluating NNMT as a possible experimental target in oncology research

At present, these efforts are confined to laboratory research. 5-Amino-1MQ is not approved for diagnosis, treatment, or prevention of any disease.

Q1: What is 5-Amino-1MQ used for in research?
A1: 5-Amino-1MQ is used in laboratory studies to investigate NNMT inhibition, NAD⁺-related metabolic pathways, adipocyte biology, and cellular energetics in in vitro, ex vivo, and non-clinical in vivo models.

Q2: What is the primary mechanism of interest for 5-Amino-1MQ?
A2: Researchers study 5-Amino-1MQ primarily as an inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme that influences nicotinamide metabolism, NAD⁺ availability, and methylation-related biochemical pathways.

Q3: In what form is this 5-Amino-1MQ product supplied?
A3: This product is supplied as lyophilized powder, intended solely for controlled laboratory use by qualified professionals.

Q4: Is 5-Amino-1MQ intended for human or veterinary use?
