2022-85-7 Fluorocytosine
5-Fluorocytosine (5-FC), also known as flucytosine, 5-fluorocytidine, Anchor, and Alla spray, is a white or off-white crystalline powder. The inhibitory effect of 5-fluorocytosine on fungi is that it enters into the cells of sensitive fungi, and under the action of cytosine deaminase, it removes the amino group to form an antimetabolite-5-fluorouracil. After Chemicalbook, it was converted to 5-fluorouracil deoxynucleoside and inhibited thymidine synthase, blocked the conversion of uridine deoxynucleoside to thymidine, and affected DNA synthesis. It has a good inhibitory effect on Candida, Cryptococcus and Geotrichum, and also has an effect on some Aspergillus, as well as branch spores and bottle fungi that cause dermatophytes. -
