| transferases (other substituted phosphate groups) | <enzyme> A class of enzymes that transfers substituted phosphate groups. Registry number: EC 2.7.8 (12 Dec 1998) |
| antibiotics, antineoplastic | Chemical substances, produced by microorganisms, inhibiting or preventing the development of neoplasms. (12 Dec 1998) |
| antimetabolites, antineoplastic | Antimetabolites that are useful in cancer chemotherapy. (12 Dec 1998) |
| antineoplastic | Inhibiting or preventing the development of neoplasms, checking the maturation and proliferation of malignant cells. Origin: Gr. Plassein = to form (18 Nov 1997) |
| antineoplastic agent | Agents inhibiting or preventing the growth of neoplasms, checking the maturation and proliferation of malignant cells. (12 Dec 1998) |
| antineoplastic agent, alkylating | A class of drugs that differs from other alkylating agents used clinically in that they are monofunctional and thus unable to cross-link cellular macromolecules. Among their common properties are a requirement for metabolic activation to intermediates with antitumour efficacy and the presence in their chemical structures of n-methyl groups, that after metabolism, can covalently modify cellular DNA. The precise mechanisms by which each of these drugs acts to kill tumour cells are not completely understood. (12 Dec 1998) |
| antineoplastic agent, combined | The use of two or more chemicals simultaneously or sequentially in the drug therapy of neoplasms. The drugs need not be in the same dosage form. (12 Dec 1998) |
| antineoplastic agent, hormonal | Antineoplastic agent that are used to treat hormone-sensitive tumours. Hormone-sensitive tumours may be hormone-dependent, hormone-responsive, or both. A hormone-dependent tumour regresses on removal of the hormonal stimulus, by surgery or pharmacological block. Hormone-responsive tumours may regress when pharmacologic amounts of hormones are administered regardless of whether previous signs of hormone sensitivity were observed. The major hormone-responsive cancers include carcinomas of the breast, prostate, and endometrium; lymphomas; and certain leukaemias. (12 Dec 1998) |
| antineoplastic agent, phytogenic | Agents, obtained from higher plants that have demonstrable cytostatic or antineoplastic activity. (12 Dec 1998) |
| antineoplastic and immunosuppressive agents | Collective grouping for substances used to arrest the proliferation of malignant cells and those that suppress the immune response. (12 Dec 1998) |
| antineoplastic drug | A drug that stops or slows the maturation and spread of tumour cells (benign or malignant). (09 Oct 1997) |
| veterinary drugs | Drugs used by veterinarians in the treatment of animal diseases. The veterinarian's pharmacological armamentarium is the counterpart of drugs treating human diseases, with dosage and administration adjusted to the size, weight, disease, and idiosyncrasies of the species. In the united states most drugs are subject to federal regulations with special reference to the safety of drugs and residues in edible animal products. (12 Dec 1998) |
| cytotoxic drugs | <pharmacology> Anti-cancer drugs which act by killing or preventing the division of cells. See: chemotherapy. (13 Nov 1997) |
| psychotropic drugs | A loosely defined grouping of drugs that have effects on psychological function. Here the psychotropic agents include the antidepressive agents, hallucinogens, and tranquillising agents (including the antipsychotics and anti-anxiety agents). (12 Dec 1998) |
