Orotic Acid丨CAS 65-86-1

Orotic acid, also known as pyrimidine-2,4-dione, is a naturally occurring compound in the body and part of the pyrimidine family. It is a carboxylic acid derivative, structurally composed of a pyrimidine ring with two oxygen atoms attached to positions 2 and 4. Orotic acid plays an important role in nucleotide metabolism and is involved in the synthesis of pyrimidine nucleotides, which are essential for DNA and RNA synthesis.

Orotic acid丨65-86-1 was first isolated from milk and has been studied for its potential role in promoting cell growth and its therapeutic applications in various medical conditions. It also exists in food, such as milk, yeast, and liver, and can be synthesized in the liver as part of normal metabolic processes.

In this article, we will explore the applications and benefits of orotic acid across different fields, ranging from biochemistry to pharmaceuticals and nutrition.

1. Nucleotide Synthesis and Cellular Growth
Orotic acid丨65-86-1 is a key intermediate in the synthesis of pyrimidine nucleotides like uridine monophosphate (UMP), which is essential for the synthesis of RNA. The process involves the conversion of orotic acid to UMP, which is then used for the formation of other important nucleotides like cytidine triphosphate (CTP), thymidine (used in DNA synthesis), and uridine. This function makes orotic acid crucial in cell division, growth, and genetic material replication.
● Cell Proliferation: As part of the metabolic pathway for nucleotide synthesis, orotic acid helps cells to divide and proliferate. It is especially important in rapidly dividing cells like those found in tissues of the bone marrow, skin, and gastrointestinal tract.
2. Supplementation in Nutritional Products
Orotic acid has been included in dietary supplements, particularly in sports nutrition and bodybuilding products. It is believed that the compound supports cellular function by enhancing cellular energy production and promoting muscle growth. Additionally, it is sometimes marketed for improving endurance and reducing fatigue during intense physical activity.
● Potential Energy Booster: The ability of orotic acid to facilitate nucleotide synthesis could have implications in enhancing cellular energy production by increasing the availability of nucleotides required for ATP (adenosine triphosphate) synthesis.
● Muscle Recovery: Some research suggests that orotic acid supplementation may aid in muscle recovery by promoting cellular regeneration and protein synthesis after intense exercise.
3. Treatment of Orotic Aciduria
One of the most important clinical applications of Orotic acid丨65-86-1 is in the treatment of orotic aciduria, a rare genetic disorder. Orotic aciduria results from a defect in the pyrimidine biosynthesis pathway, leading to an accumulation of orotic acid in the urine and various health issues such as megaloblastic anemia, growth retardation, and developmental delays.
● Therapeutic Use: In certain cases, orotic acid supplementation may be used to restore normal pyrimidine levels, potentially improving hematopoiesis (blood cell formation) and alleviating the symptoms of orotic aciduria.
4. Liver Health and Detoxification
Orotic acid has been implicated in liver health, particularly in the synthesis of lipids and the production of proteins. Some studies suggest that orotic acid supplementation may help support liver function by promoting protein synthesis and aiding in liver detoxification processes.
● Hepatoprotective Effects: Orotic acid's ability to enhance metabolic functions in the liver may help mitigate liver stress caused by toxins, medications, or liver diseases like hepatitis or cirrhosis.
5. Role in Mitochondrial Function and Aging
Recent studies have pointed to the potential role of orotic acid in mitochondrial function, specifically its involvement in maintaining mitochondrial DNA integrity and supporting the energy production processes that occur within mitochondria.
● Anti-Aging Potential: By supporting mitochondrial health, orotic acid may have potential as a longevity or anti-aging supplement, though more research is needed to confirm its efficacy in this area.
6. Pharmaceutical and Drug Development
Orotic acid derivatives, such as orotate salts, are being explored in pharmaceutical development for their antiviral and anticancer properties. Some studies have suggested that orotic acid derivatives could have activity against certain types of cancer cells by promoting cell differentiation or inducing apoptosis (programmed cell death).
● Anticancer Research: Orotic acid and its derivatives are being researched for their potential role in cancer therapy, particularly as chemotherapy agents that could selectively target tumor cells.
● Antiviral Agents: There is ongoing research into the antiviral potential of orotic acid derivatives, particularly in relation to herpes viruses and HIV, although clinical data remains limited.

1. Support for DNA and RNA Synthesis
Orotic acid's primary role in nucleotide metabolism is its involvement in the synthesis of RNA and the synthesis of DNA precursors. This function is critical for cellular replication, growth, and repair. Ensuring adequate levels of orotic acid can support cell division and tissue regeneration, making it important for wound healing, immune response, and tissue repair.
2. Enhances Cellular Energy Production
Orotic acid丨65-86-1 is a precursor to UMP and other pyrimidine nucleotides that are integral to the synthesis of ATP. ATP is the energy currency of the cell, supporting functions like muscle contraction, protein synthesis, and cell signaling. By contributing to nucleotide biosynthesis, orotic acid helps maintain cellular energy homeostasis.
● Improved Endurance: For athletes and individuals engaged in regular physical exertion, orotic acid may help improve endurance and muscle recovery by ensuring optimal ATP production.
3. Cognitive Function and Brain Health
There is some evidence to suggest that orotic acid may have a role in supporting brain health, as the pyrimidine nucleotides are essential for the synthesis of neurotransmitters and brain cell function. Adequate orotic acid levels may contribute to better cognitive function, learning, and memory.
● Neuroprotective Effects: The compound's involvement in cellular repair processes may offer neuroprotective benefits, especially in conditions like neurodegeneration or cognitive decline.
4. Cardiovascular Health
Orotic acid's role in nucleotide synthesis also extends to the regulation of blood cells and overall cardiovascular function. By supporting proper blood cell formation, orotic acid may help maintain circulatory health and contribute to the production of red blood cells, thereby improving oxygen delivery throughout the body.
● Anemia Treatment: In conditions such as megaloblastic anemia where there is an issue with proper blood cell formation, orotic acid can potentially restore the proper levels of red blood cells.
5. Aids in Detoxification
By supporting liver function, orotic acid may help in the detoxification of harmful substances in the body. It supports the production of proteins and lipids that are important for removing toxins from the bloodstream and maintaining liver health.

Orotic acid丨65-86-1 is a compound with significant biological and therapeutic potential, primarily due to its role in pyrimidine metabolism and nucleotide synthesis. Its applications range from biochemical synthesis, cellular growth, and sports nutrition to more targeted uses in the treatment of genetic disorders like orotic aciduria. In addition, it holds promise as a component in drug development for conditions like cancer and viral infections. The compound's potential benefits include supporting energy production, improving cellular function, promoting tissue repair, and possibly offering neuroprotective effects. While further research is needed, orotic acid represents a fascinating area of study with wide-ranging implications for health and well-being.
