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. | 1.96 | 1 | 0 | nucleobase analogue; organofluorine compound | antimetabolite; antineoplastic agent; environmental contaminant; immunosuppressive agent; radiosensitizing agent; xenobiotic |
mitomycin Mitomycin: An antineoplastic antibiotic produced by Streptomyces caespitosus. It is one of the bi- or tri-functional ALKYLATING AGENTS causing cross-linking of DNA and inhibition of DNA synthesis.. mitomycin : A family of aziridine-containing natural products isolated from Streptomyces caespitosus or Streptomyces lavendulae. | 1.96 | 1 | 0 | mitomycin | alkylating agent; antineoplastic agent |
alanine Alanine: A non-essential amino acid that occurs in high levels in its free state in plasma. It is produced from pyruvate by transamination. It is involved in sugar and acid metabolism, increases IMMUNITY, and provides energy for muscle tissue, BRAIN, and the CENTRAL NERVOUS SYSTEM.. alanine : An alpha-amino acid that consists of propionic acid bearing an amino substituent at position 2. | 2.39 | 2 | 0 | alanine zwitterion; alanine; L-alpha-amino acid; proteinogenic amino acid; pyruvate family amino acid | EC 4.3.1.15 (diaminopropionate ammonia-lyase) inhibitor; fundamental metabolite |
thapsigargin Thapsigargin: A sesquiterpene lactone found in roots of THAPSIA. It inhibits SARCOPLASMIC RETICULUM CALCIUM-TRANSPORTING ATPASES.. thapsigargin : An organic heterotricyclic compound that is a hexa-oxygenated 6,7-guaianolide isolated fron the roots of Thapsia garganica L., Apiaceae. A potent skin irritant, it is used in traditional medicine as a counter-irritant. Thapsigargin inhibits Ca(2+)-transporting ATPase mediated uptake of calcium ions into sarcoplasmic reticulum and is used in experimentation examining the impacts of increasing cytosolic calcium concentrations. | 2.03 | 1 | 0 | butyrate ester; organic heterotricyclic compound; sesquiterpene lactone | calcium channel blocker; EC 3.6.3.8 (Ca(2+)-transporting ATPase) inhibitor |
mercaptopurine Mercaptopurine: An antimetabolite antineoplastic agent with immunosuppressant properties. It interferes with nucleic acid synthesis by inhibiting purine metabolism and is used, usually in combination with other drugs, in the treatment of or in remission maintenance programs for leukemia.. purine-6-thiol : A thiol that is the tautomer of mercaptopurine.. mercaptopurine : A member of the class of purines that is 6,7-dihydro-1H-purine carrying a thione group at position 6. An adenine analogue, it is used in the treatment of acute lymphocytic leukemia (ALL), chronic myeloid leukemia (CML), Crohn's disease, and ulcerative colitis. | 1.96 | 1 | 0 | aryl thiol; purines; thiocarbonyl compound | anticoronaviral agent; antimetabolite; antineoplastic agent |

vitamin k 1 Vitamin K 1: A family of phylloquinones that contains a ring of 2-methyl-1,4-naphthoquinone and an isoprenoid side chain. Members of this group of vitamin K 1 have only one double bond on the proximal isoprene unit. Rich sources of vitamin K 1 include green plants, algae, and photosynthetic bacteria. Vitamin K1 has antihemorrhagic and prothrombogenic activity.. phylloquinone : A member of the class of phylloquinones that consists of 1,4-naphthoquinone having methyl and phytyl groups at positions 2 and 3 respectively. The parent of the class of phylloquinones. | 1.98 | 1 | 0 | phylloquinones; vitamin K | cofactor; human metabolite; plant metabolite |
herbimycin herbimycin: herbicidal antibiotic produced by Streptomyces sp.; see also herbimycin B; structure for herbimycin A in second source. herbimycin : A 19-membered macrocyle incorporating a benzoquinone ring and a lactam functionality. It is an ansamycin antibiotic that induces apoptosis and displays antitumour effects. | 1.98 | 1 | 0 | 1,4-benzoquinones; lactam; macrocycle | antimicrobial agent; apoptosis inducer; herbicide; Hsp90 inhibitor; tyrosine kinase inhibitor |
