fluorouracil Fluorouracil: A pyrimidine analog that is an antineoplastic antimetabolite. It interferes with DNA synthesis by blocking the THYMIDYLATE SYNTHETASE conversion of deoxyuridylic acid to thymidylic acid.. 5-fluorouracil : A nucleobase analogue that is uracil in which the hydrogen at position 5 is replaced by fluorine. It is an antineoplastic agent which acts as an antimetabolite - following conversion to the active deoxynucleotide, it inhibits DNA synthesis (by blocking the conversion of deoxyuridylic acid to thymidylic acid by the cellular enzyme thymidylate synthetase) and so slows tumour growth. | 2.01 | 1 | 0 | nucleobase analogue; organofluorine compound | antimetabolite; antineoplastic agent; environmental contaminant; immunosuppressive agent; radiosensitizing agent; xenobiotic |
deoxycytidine [no description available] | 2.01 | 1 | 0 | pyrimidine 2'-deoxyribonucleoside | Escherichia coli metabolite; human metabolite; mouse metabolite; Saccharomyces cerevisiae metabolite |
doxifluridine doxifluridine : A pyrimidine 5'-deoxyribonucleoside that is 5-fluorouridine in which the hydroxy group at the 5' position is replaced by a hydrogen. It is an oral prodrug of the antineoplastic agent 5-fluorouracil. Designed to circumvent the rapid degradation of 5-fluorouracil by dihydropyrimidine dehydrogenase in the gut wall, it is converted into 5-fluorouracil in the presence of pyrimidine nucleoside phosphorylase. | 2.01 | 1 | 0 | organofluorine compound; pyrimidine 5'-deoxyribonucleoside | antimetabolite; antineoplastic agent; prodrug |

capecitabine Capecitabine: A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.. capecitabine : A carbamate ester that is cytidine in which the hydrogen at position 5 is replaced by fluorine and in which the amino group attached to position 4 is converted into its N-(penyloxy)carbonyl derivative. Capecitabine is a antineoplastic agent used in the treatment of cancers. | 2.01 | 1 | 0 | carbamate ester; cytidines; organofluorine compound | antimetabolite; antineoplastic agent; prodrug |
5-iodouracil 5-iodouracil: RN given refers to parent cpd. 5-iodouracil : An organoiodine compound consisting of uracil having an iodo substituent at the 5-position. | 2.01 | 1 | 0 | organoiodine compound | antimetabolite |
