Cancer Chemotherapy - Pharmacology Flashcards
Major Classes of Chemotherapy Drugs (4)
1) Alkylating Agents
2) Anti-metabolites
3) Anti-tumor Antibiotics
4) Natural Product Drugs (Including Microtubule Inhibitors)
CCS vs. CCNS
Cell Cycle Specific vs. Cell-Cycle Non-specific - Does it knock out a specific phase of the cell cycle
Major Cell Cycle Stages (4) + Drugs Acting At Each Stage
1) G1 - Alkylating Agents - But they are CCNS
2) S - Antimetabolites
3) G2 - Bleomycin
4) Mitosis - Microtubule Inhibitors
Anti-Metabolites - Names (6)
1) Azathioprine
2) 6-MP - 6 mercaptopurine
3) Cladribine (2-CDA)
4) Cytarabine
5) 5-FU - 5-Fluorouracil
6) Methotraxate
Alkylating Agents (5)
1) Cyclophosphamide
2) Busulfan
3) Nitrosoureas
4) Cisplatin
5) Carboplatin
4-5 Are Platinum Analogs
Antitumor Antibiotics (3)
1) Bleomycin
2) Dactinomycin (Actinomycin D)
3) Doxorubicin
Cyclophosphamide - CCS/CCNS + Mechanism + Toxicity
CCS/CCNS - Alkylating Agent - CCNS
Mechanism - Cross-Links DNA at N7 (Prevents Replication)
Toxicity - Hemorrhagic Cystitis - Give Mensa Concurrently
Busulfan - CCS/CCNS + Mechanism + Key Use (2) + Toxicity (2)
CCS/CCNS - Alkylating Agent - CCNS
Mechanism - Cross Links DNA (Prevents Replication)
Key Use - CML +
CLASS ONLY USE = Gutathione-Transferase Deficiency
Toxicity - Pulmonary Fibrosis + Myelosuppression
Nitrosoureas - CCS/CCNS + Mechanism + Key Use + Toxicity
CCS/CCNS - Alkylating Agent - CCNS
E.g. Carmustine
Mechanism - Cross Link DNA (Prevents Replication) - Crosses Blood Brain Barrier
Key Use - Brain Tumors (GBM)
Toxicity - CNS Toxicity
Carmustine - CCS/CCNS + Mechanism + Key Use + Toxicity
CCS/CCNS - Alkylating Agent - CCNS - Nitrosoureas
Mechanism - Cross Link DNA (Prevents Replication) - Crosses Blood Brain Barrier
Key Use - Brain Tumors (GBM)
Toxicity - CNS Toxicity
Procarbazine - CCS/CCNS + Mechanism + Toxicity
CLASS ONLY
CCS/CCNS - Alkylating Agent - CCNS - Nonclassic
Mechanism - Inhibits DNA synthesis + inhibit MAO
Toxicity - High Risk of Secondary Cancer
Cisplatin - CCS/CCNS + Mechanism + Toxicity
CCS/CCNS - Alkylating Agent - CCNS
Mechanism - Cross-Links DNA (Prevents Replication)
Toxicity - Nephrotocity + Ototoxicity (C for Ears)
Carboplatin - CCS/CCNS + Mechanism + Toxicity
CLASS ONLY
CCS/CCNS - Alkylating Agent - CCNS
Mechanism - Cross-Links DNA (Prevents Replication)
Toxicity - Myelosuppression
Oxaliplatin - CCS/CCNS + Mechanism + Toxicity
CLASS ONLY
CCS/CCNS - Alkylating Agent - CCNS
Mechanism - Cross-Links DNA (Prevents Replication)
Toxicity - Neurotoxicity
Methotrexate - CCS/CCNS + Mechanism + Toxicity
CCS/CCNS - Antimetabolite - CCS - S Phase
Mechanism - Folic Acid Analog - Inhibits Dihydrofolate reductase which inhibits dTMP and DNA Synthesis
Toxicity - Myelosuppression - Reversed with Leucovorin + Mucositis (mouth ulcers)
5-Fluorouracil - CCS/CCNS + Mechanism + Key Use + Toxicity
CCS/CCNS - Antimetabolite - CCS - S Phase
Mechanism - Pyrimidine Analog - Inhibits thmidylate Synthase
Toxicity - Non-Reversible Myelosuppresion -
CLASS ONLY - Metabolized by Dihydropyridine DH (Deficiency leads to massive toxicity)
Capecitabine - CCS/CCNS + Mechanism + Toxicity
CLASS ONLY
CCS/CCNS - Antimetabolite - CCS - S Phase
Mechanism - Thmidine Phosphophylate converts it to 5-FU
Toxicity - Hand and Foot Syndrome
