Etoposide
Topoisomerase II inhibitor Cell cycle specific for S-phase and G2. Causes strand breaks in DNA IV and oral.
Doxyrubicin
Intercolating (between DNA like ethidium bromide stopping DNA and RNA synthesis) and Topo II inhibitor IV. Cell cycle nonspecific. Vesicant. Radiation recall. BMS. Urine Red. Antibiotic
Methotrexate
Analog of tetrahydrofolate inhibits DHFR. IV and oral
Alkylation of the urine makes the methotrexate excretion in the urine less toxic
Cotreat with Leucovorin and Glucarpidase
Leucovorin
Reduced form of folate bypasses DHFR and supplies 1C pool to help good cells with methotrexate treatment
Glucarpidase
enzyme used to lower methotrexate into inactive DAMPA for alternative route of elimination than kidney. IV
5-Fluorouracil
inhibits thyamine Synthase Cell cycle specific antimetabolite. Affects pyrimadine synthesis AE: Acute Cerebellar syndrome, lowest theraputic index. Liver elimination

Analog of purines. IV Blocks DNA polymerase Cell cycle specific to S-Phase
Paclitaxiel
Antimitotic: Prevents Depolymerization of microtubules preventing Metaphase->anaphase transition. IV treatment
Carmustine
Antineoplastic Is an alkylating agent causes cross links in DNA and RNA leading to cell death. Crosses the BBB easily, cell cycle specific. Wafers inserted into the brain and IV. Lipophillic. Nitrosoureas
Temozolomide
Alkylating agent, methylation of RNA and DNA. Crosses BBB easily; lipophillic.
Vincristine
Depolymerization of microtubules preventing Metaphase->anaphase transition. IV treatment. Is small so crosses the BBB very well, but is effluxed out of the brain so is not as good as temozolomide and carmustine in treating brain tumors.
Pemetrexed
Analog of tetrahydrofolate inhibits DHFR. IV and oral
Alkylation of the urine makes the methotrexate excretion in the urine less toxic
Cotreat with Leucovorin and Glucarpidase
Pralatrexate
Analog of tetrahydrofolate inhibits DHFR. IV and oral
Alkylation of the urine makes the methotrexate excretion in the urine less toxic
Cotreat with Leucovorin and Glucarpidase
6-Mercaptopurine
S-phase specific, Inhibits purine synthesis by blocking guanylyl Kinase, resulting in pseudofeedback inhibition leading to buildup of AMP, GTP which must be made through salvage pathway. Useful for leukemia
AE: bone marrow suppression, Tumor lysis syndrome, increased uric acid
Capecitabine
inhibits thyamine Synthase Cell cycle specific antimetabolite. Affects pyrimadine synthesis AE: Acute Cerebellar syndrome, lowest theraputic index. Liver elimination same as 5FU
Azithroprine
S-phase specific, Inhibits purine synthesis by blocking guanylyl Kinase, resulting in pseudofeedback inhibition leading to buildup of AMP, GTP which must be made through salvage pathway. Useful for leukemia
AE: bone marrow suppression, Tumor lysis syndrome
Not anticancer
6-Thioguanine
Inhibits Guanylyl kinase
S-phase specific, Inhibits purine synthesis by blocking guanylyl Kinase, resulting in pseudofeedback inhibition Useful for leukemia
AE: bone marrow suppression, Tumor lysis syndrome increased uric acid
Allopurinol
Inhibits xanthine oxidase, preventing uric acid buildup and gout associated with 6 mercaptopurine due to tumor cell lysis. Use with 6- mercaptopurine results in excessive toxicity, reduce 6mcp dose
