** The Other Half of This Lec. is in aferdo01's StudyStack ** | . |
Alkylating agents = ? | * Nitrogen mustards and Nitrosoureas |
Nitrogen mustards ? | * melphalan --- ifosfamide |
Nitrosoureas ? | * carmustine --- lomustine |
Platinum compounds | * cisplatin --- carboplatin |
*Nitrogen Mustards* .... Melphalan and Ifosfamide uses ? | * Melphalan = Ovarian cancer and multiple myeloma...... * Ifosfamide = testicular cancer |
Nitrogen Mustard (Mel. and Ifo.) MOA = ? | * Alkylate DNA at N7 of guanine (a base) by CROSS-LINKING the cells --> apoptosis... * Unique Thing = Good in both actively dividing and resting cells ! |
Melphalan SEs = ? | * BLACK BOX = Bone marrow suppression (dose limiting) and Hypersensitivity reactions...... * Pulmonary toxicity (cause fibrosis/pneumoitis) |
Ifosfamide SEs = ? | * BLACK BOX = CNS toxicity, Hemorrhagic cystitis, and Nephrotoxicity (can cause renal failure)...... * TmT of Cystitis = Hydration and MESNA........ * Other tox. = dose limiting BMD, Caridotoxicity, and Pulmonary Toxicity again |
*Nitrosoureas*.... Carmustine use ? | * UNIQUE: Can cross BBB so REALLY good for BRAIN tumors/cancers |
Carmustine MOA = ? | * Interferes with DNA & RNA function by alkylation and cross-linking and by carbamylation of amino acids in protein...... * Simple Terms: Alkylates (messes DNA up) and Modifies Proteins (carbamylation) |
Lomustine use = ? | * Also use in Brain tumors, but also can use for Multiple myeloma, Hodgkin's lymphoma |
Lomustine MOA = ? | * Inhibits DNA & RNA synthesis by alkylation of DNA and carbamylation of DNA polymerase.... * Simple Terms: Modifies the DNA polymerase |
Carmustine and Lomustine SEs = ? | * Worst DRUG for BMD ! --> thrombocytopenia and leukopenia..... * The BMD can be delayed,dose related, etc, so need to monitor it ATLEAST 6 months after a dose is given.... * CNS, renal, hepatic & pulmonary toxicity are also dose limiting |
*Platinum complexes*.... Cisplatin use = ? | * One of the most commonly used drugs ..... * Colon in testicular, ovarian, and bladder |
Cisplatin MOA = ? | *Water replaces chloride and Creates reactive molecule, which bind to guanine and causes inter- and intra- strand DNA crosslinks ....... * CCNS (kills in all cell cycle stages) |
How to prevent Cisplatin toxicity ? | * Give Chloride, b/c low Cl creates a favorable environment for the drug to work --> Toxicity |
Cisplatin ACUTE SEs = ? | * WORST Drug for N/V = High Emetic Frequency ( so give an antiemetic before)...... * BLACK BOX: Hypersensitivity / Anaphylactic-like reactions (need loaded up with -roids, antihists., or epi. before tmt to prevent this) |
Cisplatin DELAYED SEs = ? | *pop up days --> weeks later..... * BLACK BOX: Nephrotoxicity - One of the most nephrotoxic drugs..... * BLACK BOX: Ototoxicity in KIDS (need to monitor YRS later) |
Used to treat DELAYED SEs = ? | * Hydration with Chloride...... * Also give Amifostine |
Carboplatin use = ? | * drug is a 2nd generation analog.....* Ovarian cancer |
Carboplatin SEs = ? | * Same MOA as Cis..... * SEs = Less TOXIC in everything, except for BMD (dose limiting) |
*Antimetabolites*.... Methotrexate Use = ? | * LOTS: Treatment of leukemias; lymphomas -- Breast cancer -- Lung cancer -- GVHD (prophylaxis) -- Psoriasis -- Rheumatoid arthritis |
MTX MOA = ? | * Depletes TMP --> Prevents regenerated folate from being reactivated to be used to make the TMP..... * SIMPLE: inhibits dihydrofolate reductase (DHFR) --> low TMP for DNA synth. |
MTX SEs = ? | * BLACK BOX: BMD (dose-limiting, GI, Hepatotoxic, Pneumonitis, Derm. issues, and Renal Issues |
*Antimetabolites - Pyrimidine analogs*.... 5-Fluorouracil (5-FU) Use = ? | * Widely Used agent in the Tmt of Breast Cancer, Topical for Basal Cancer, and for Colorectal Cancer |
5-Fluorouracil MOA = ? | * Converted in target cells to 5F-dUMP (nucleobase to nucleoside to nucleotide)... * 5F-dUMP covalently binds to thymidylate synthetase with FH4 (reduced folate, which Blocks conversion of dUMP to TMP...* Leads to cell death by depleting TTP |
5-FU can also ? | * Also converted to FdUTP and FUTP, which Inhibits DNA & RNA synthesis.... * Unique bc this drug can inhibit BOTH RNA and DNA..... * Also, it is a suicide inhibitor = binds permanently |
5-FU SEs = ? | * Classic Anti-Cancer SEs, nothing major.... * GI, BMD, N/V |
Gemcitabine Use = ? | * breast, non-small cell lung, pancreatic, ovarian cancer... * Nothing Big stands out |
Gemcitabine MOA = ? | * Is a Deoxycytidine analog (phosphorylated to mono-, di-, and triphosphate)...... * inhibits ribonucleotide reductase = lowers dNTPs (lowers diphospahtes).... * inhibits DNA polymerase ..... * incorporates into DNA (chain termination) |
Gemcitabine SEs = ? | * Toxicity – Myelosuppression (neutropenia) (dose limiting) |
*Hydroxyurea* Use = ? | * Lots.... * Melanoma, chronic myelocytic leukemia (CML), ovarian cancer; management of sickle cell patients |
Hydroxyurea MOA = ? | * Inhibits ribonucleotide reductase... * Inhibition results in depletion of intracellular dNTP pools leading to inhibition of DNA synthesis |
Hydroxyurea SEs = ? | * BLACK BOX: Developing a Secondary Malignancy...... * Myelosuppression (dose limiting)..... * Cutaneous Vasculitic issues (look like ulcers on the body) |
