High Purity Peptides Aicar

Description

AICAR (5-aminoimidazole-4-carboxamide-1-β-D-ribofuranoside) is a substance produced naturally by the body that stimulates AMP activated protein kinase (AMPK), a protein that regulates metabolism in a variety of ways. AMPK acts as an energy regulator and is activated during exercise or other circumstances that use up cellular energy.

The AMPK-stimulating AICAR can also be synthesized in a lab and is being evaluated in preclinical research and human clinical trials as a therapeutic agent to treat certain metabolic disorders in humans.

Cell-permeable, allosteric activator of AMP-activated protein kinase (AMPK). Augments proliferation, differentiation and mineralization of osteoblastic MC3T3-EI cells and attenuates psychosine-induced expression of proinflammatory cytokines and iNOS in astrocytes. Promotes osteogenic differentiation of hAMSCs and BM-MSCs in vitro.

The drug has also been shown as a potential treatment for diabetes by increasing the metabolic activity of tissues by changing the physical composition of muscle.

How does Aicar work?

Aicar (5-Aminoimidazole-4-carboxamide ribonucleotide) is a peptide-like compound that plays a role in energy metabolism and endurance enhancement. It is often researched for its effects on cellular energy levels and physical performance. 

1. Activates AMPK Pathways

AMP-Activated Protein Kinase (AMPK): Aicar directly activates AMPK, a cellular energy sensor responsible for regulating energy balance.

Energy Boost: By stimulating AMPK, Aicar promotes the usage of stored fats for energy and increases glucose uptake in muscle cells.

2. Enhances Fat Metabolism

Aicar enhances fatty acid oxidation, helping the body to burn fat for fuel, especially during prolonged physical activity or low-energy states.

It prevents the accumulation of excess fat in cells, making it a potential candidate for metabolic improvement.

3. Increases Glucose Uptake

Aicar facilitates glucose uptake in muscle tissues, mimicking the effects of exercise.

This makes it beneficial for improving insulin sensitivity and managing blood sugar levels.

4. Promotes Mitochondrial Biogenesis

By stimulating AMPK, Aicar indirectly enhances mitochondrial function and biogenesis, leading to improved endurance and energy efficiency.

This effect is of particular interest to athletes and researchers exploring performance enhancement.

5. Simulates Exercise-Like Effects

Aicar can mimic some of the benefits of physical exercise without actual movement, such as improved energy metabolism and enhanced endurance capacity.

Potential Applications

Endurance Enhancement: Aicar has been studied for its ability to boost stamina and performance in athletes.

Metabolic Disorders: It may help improve conditions like obesity, diabetes, and metabolic syndrome by regulating energy balance.

Research Purposes: Aicar is often used in studies to explore cellular metabolism and energy pathways.

Key Considerations

Aicar is typically used in research settings and is not approved for general medical or athletic use.

Prolonged use or misuse may lead to adverse effects, such as energy imbalances or potential interference with natural metabolic processes.

Why is Aicar so popular?

Enhanced Endurance: Aicar is known to stimulate AMP-activated protein kinase (AMPK), which can increase cellular energy production and improve endurance levels.

Fat Metabolism: It promotes the breakdown of fats for energy, making it attractive to those aiming for fat loss or improved body composition.

Non-Hormonal: Unlike anabolic steroids, Aicar does not affect hormonal levels, making it a preferred choice for individuals avoiding hormonal interventions.

Research and Medical Potential: It has been studied for its potential in treating metabolic disorders and improving mitochondrial function, adding to its appeal in the scientific and athletic communities.

Versatility: Aicar's ability to enhance performance without significant side effects (when used responsibly) makes it a sought-after compound among athletes and fitness enthusiasts.

How do AICAR and AMPK impact performance?

Once activated by AICAR, AMPK works to make energy more available. For example, it increases the usage of fat for energy and causes cells to make more mitochondria (the cells' powerhouses or energy creators). AMPK basically ensures that the various tissues in the body don't run out of energy.

There are many circumstances that activate AMPK naturally, including hypoxia (low oxygen levels during exercise or at elevation), hypoglycemia (low blood sugar with exercise or fasting), the use of cellular energy during muscle contraction, and anything that disrupts energy creation within cells.

The effects of activating AMPK are extremely complex since it is involved in so many different metabolic pathways of the body. To date, the medical community has not found a way to target AMPK in a way that allows for the treatment of diseases in humans, although research has suggested it plays a role in diabetes, heart disease, and cancer.

Benefit

Some of the potential benefits and applications of AICAR that have been explored in scientific research include:

● Metabolic Regulation: AICAR's activation of AMPK may help regulate cellular energy homeostasis. This could have implications for metabolic disorders, such as obesity and type 2 diabetes, where improving insulin sensitivity and glucose uptake are important.

● Exercise Performance: AICAR has been studied for its potential to enhance endurance and exercise performance. Activation of AMPK may lead to increased energy production and utilization in skeletal muscles, potentially improving an athlete's capacity for aerobic exercise.

● Cardiovascular Health: Some research suggests that AICAR may have cardioprotective effects by promoting blood vessel health, reducing inflammation, and protecting against oxidative stress. These effects could be beneficial for individuals at risk of cardiovascular diseases.

● Neuroprotection: AICAR has been investigated for its potential neuroprotective properties, particularly in animal models of neurodegenerative diseases. It may support neuronal survival and function.

● Cancer Research: In laboratory studies, AICAR has been explored as a potential adjunctive therapy for cancer. It may inhibit the growth of cancer cells and promote their apoptosis (programmed cell death).

Mechanism of action

The nucleoside form of AICAR, acadesine, is an analog of adenosine that enters cardiac cells to inhibit adenosine kinase and adenosine deaminase. It enhances the rate of nucleotide re-synthesis increasing adenosine generation from adenosine monophosphate only during conditions of myocardial ischemia. In cardiac myocytes, acadesine is phosphorylated to AICAR to activate AMPK without changing the levels of the nucleotides. AICAR is able to enter the de novo synthesis pathway for adenosine synthesis to inhibit adenosine deaminase causing an increase in ATP levels and adenosine levels.
