Nystatin丨CAS 1400-61-9

Nystatin, with the Chemical Abstracts Service (CAS) number 1400-61-9, is a polyene antifungal medication derived from the bacterium Streptomyces noursei. It is widely used to treat fungal infections, particularly those caused by Candida species. Nystatin丨1400-61-9 is effective against a broad spectrum of fungi and is commonly used in both topical and oral formulations.

1. Medical and Therapeutic Uses:

- Antifungal Treatment: Nystatin is primarily used to treat fungal infections, particularly those caused by Candida species. It is effective against oral thrush, vaginal yeast infections, and cutaneous candidiasis.

- Topical Applications: Nystatin is available in creams, ointments, and powders for treating skin and mucosal fungal infections.

- Oral Suspension: It is used as an oral suspension to treat oral and gastrointestinal candidiasis, especially in immunocompromised patients.

- Prophylaxis: Nystatin is sometimes used prophylactically to prevent fungal infections in high-risk patients, such as those undergoing chemotherapy or organ transplantation.

2. Veterinary Medicine:

- Nystatin丨1400-61-9 is used to treat fungal infections in animals, including pets and livestock. It is particularly effective against candidiasis in animals.

3. Research and Development:

- Nystatin is used in laboratory research to study fungal biology and the mechanisms of antifungal resistance. It is also used as a tool to investigate membrane permeability and ion transport in cells.

1. Broad-Spectrum Antifungal Activity:

- Nystatin is effective against a wide range of fungal pathogens, particularly Candida species, making it a versatile treatment option for various fungal infections.

2. Low Systemic Absorption:

- When used topically or as an oral suspension, Nystatin has minimal systemic absorption, reducing the risk of systemic side effects. This makes it safe for use in vulnerable populations, including infants and immunocompromised patients.

3. Safety and Tolerability:

- Nystatin丨1400-61-9 is generally well-tolerated, with few side effects. Topical and oral formulations are safe for long-term use when prescribed appropriately.

4. Prophylactic Use:

- Its use in preventing fungal infections in high-risk patients highlights its importance in clinical settings, particularly in oncology and transplant medicine.

5. Research Utility:

- Nystatin's ability to disrupt fungal cell membranes makes it a valuable tool for studying fungal biology and developing new antifungal therapies.

Nystatin works by binding to ergosterol, a key component of fungal cell membranes. This binding creates pores in the membrane, leading to the leakage of intracellular contents and ultimately cell death. Because human cells contain cholesterol instead of ergosterol, Nystatin selectively targets fungal cells without significantly affecting human cells.

- Nystatin丨1400-61-9 is generally safe for topical and oral use, but it should not be administered intravenously due to the risk of severe toxicity.

- Side effects are rare but may include mild irritation, itching, or rash at the application site. Oral use may cause gastrointestinal discomfort in some individuals.

- It should be stored in a cool, dry place, away from direct sunlight and moisture, to maintain its stability.

Nystatin丨1400-61-9 is a highly effective and widely used antifungal medication with applications in human and veterinary medicine. Its broad-spectrum activity, safety profile, and minimal systemic absorption make it a valuable treatment for fungal infections, particularly those caused by Candida species. Additionally, its role in research underscores its importance in advancing our understanding of fungal biology and developing new therapeutic strategies. Proper use and storage ensure its efficacy and safety in clinical and research settings.
