procarbazine
Procarbazine: An antineoplastic agent used primarily in combination with mechlorethamine, vincristine, and prednisone (the MOPP protocol) in the treatment of Hodgkin's disease.. procarbazine : A benzamide obtained by formal condensation of the carboxy group of 4-[(2-methylhydrazino)methyl]benzoic acid with the amino group of isopropylamine. An antineoplastic chemotherapy drug used for treatment of Hodgkin's lymphoma. Metabolism yields azo-procarbazine and hydrogen peroxide, which results in the breaking of DNA strands. | 1.97 | 1 | 0 | benzamides;

prednisone
Prednisone: A synthetic anti-inflammatory glucocorticoid derived from CORTISONE. It is biologically inert and converted to PREDNISOLONE in the liver.. prednisone : A synthetic glucocorticoid drug that is particularly effective as an immunosuppressant, and affects virtually all of the immune system. Prednisone is a prodrug that is converted by the liver into prednisolone (a beta-hydroxy group instead of the oxo group at position 11), which is the active drug and also a steroid. | 1.97 | 1 | 0 | 11-oxo steroid;

nimustine
Nimustine: Antineoplastic agent especially effective against malignant brain tumors. The resistance which brain tumor cells acquire to the initial effectiveness of this drug can be partially overcome by the simultaneous use of membrane-modifying agents such as reserpine, calcium antagonists such as nicardipine or verapamil, or the calmodulin inhibitor, trifluoperazine. The drug has also been used in combination with other antineoplastic agents or with radiotherapy for the treatment of various neoplasms.. nimustine : An organochlorine compound that is urea in which the two hydrogens on one of the amino groups are replaced by nitroso and 2-chloroethyl groups and one hydrogen from the other amino group is replaced by a 4-amino-2-methylpyrimidin-5-ylmethyl] group. An antineoplastic agent especially effective against malignant brain tumors. | 2 | 1 | 0 | aminopyrimidine;

o-(6)-methylguanine
O-(6)-methylguanine: structure. 6-O-methylguanine : A methylguanine in which the methyl group is positioned on the oxygen at position 6. Formed in DNA by alkylation of the oxygen atom of guanine, most often by N-nitroso compounds and sometimes due to methylation by other compounds such as endogenous S-adenosylmethionine, it base-pairs to thymine rather than cytidine, causing a G:C to A:T transition in DNA.. methylguanine : A 2-aminopurine that is guanine bearing a single methyl substituent. | 2.38 | 2 | 0 | methylguanine | mutagen |
