Flucytosine

Description:

Flucytosine, with the CAS number 2022-85-7, is an antifungal medication primarily used to treat serious fungal infections, particularly those caused by Candida and Cryptococcus species. It is a pyrimidine analog that interferes with nucleic acid synthesis by inhibiting thymidylate synthase, ultimately disrupting fungal DNA and RNA synthesis. Flucytosine is typically administered in conjunction with other antifungal agents, such as amphotericin B, to enhance its efficacy and reduce the risk of resistance. The substance is well-absorbed when taken orally and is distributed widely throughout the body, including the central nervous system, making it effective for treating cryptococcal meningitis. Flucytosine is generally well-tolerated, but it can cause side effects such as bone marrow suppression and gastrointestinal disturbances. Its use requires careful monitoring of renal function and blood counts due to potential toxicity. Overall, flucytosine is a valuable tool in the antifungal arsenal, particularly for immunocompromised patients.

5-Fluorocytosine

CAS: 2022-85-7

Flucytosine is an antifungal agent that inhibits the synthesis of DNA by preventing the conversion of deoxyuridine monophosphate to uracil monophosphate. It is used as an antiretroviral therapy in combination with other drugs, such as zidovudine and dideoxyinosine, to treat HIV infections. Flucytosine has been shown to have a strong antitumor response in a model system involving mice with sarcoma 180. This drug can cause serious side effects, including drug interactions and resistance mutations in microorganisms. These side effects are often observed in patients undergoing cancer chemotherapy or immunosuppressive therapy.
