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. | 7.36 | 2 | 0 | nucleobase analogue; organofluorine compound | antimetabolite; antineoplastic agent; environmental contaminant; immunosuppressive agent; radiosensitizing agent; xenobiotic |
thymidine [no description available] | 7.65 | 3 | 0 | pyrimidine 2'-deoxyribonucleoside | Escherichia coli metabolite; human metabolite; metabolite; mouse metabolite |
bromouracil Bromouracil: 5-Bromo-2,4(1H,3H)-pyrimidinedione. Brominated derivative of uracil that acts as an antimetabolite, substituting for thymine in DNA. It is used mainly as an experimental mutagen, but its deoxyriboside (BROMODEOXYURIDINE) is used to treat neoplasms.. 5-bromouracil : A pyrimidine having keto groups at the 2- and 4-positions and a bromo group at the 5-position. Used mainly as an experimental mutagen. | 2.66 | 3 | 0 | nucleobase analogue; pyrimidines | mutagen |

bromodeoxyuridine Bromodeoxyuridine: A nucleoside that substitutes for thymidine in DNA and thus acts as an antimetabolite. It causes breaks in chromosomes and has been proposed as an antiviral and antineoplastic agent. It has been given orphan drug status for use in the treatment of primary brain tumors. | 2.66 | 3 | 0 | pyrimidine 2'-deoxyribonucleoside | antimetabolite; antineoplastic agent |

zidovudine Zidovudine: A dideoxynucleoside compound in which the 3'-hydroxy group on the sugar moiety has been replaced by an azido group. This modification prevents the formation of phosphodiester linkages which are needed for the completion of nucleic acid chains. The compound is a potent inhibitor of HIV replication, acting as a chain-terminator of viral DNA during reverse transcription. It improves immunologic function, partially reverses the HIV-induced neurological dysfunction, and improves certain other clinical abnormalities associated with AIDS. Its principal toxic effect is dose-dependent suppression of bone marrow, resulting in anemia and leukopenia.. zidovudine : A pyrimidine 2',3'-dideoxyribonucleoside compound having a 3'-azido substituent and thymine as the nucleobase. | 1.97 | 1 | 0 | azide; pyrimidine 2',3'-dideoxyribonucleoside | antimetabolite; antiviral drug; HIV-1 reverse transcriptase inhibitor |
