Study Notes
DNA Damaging Agents
- Alkylating Agents: Alkylate DNA, creating cyclic structures and attaching to guanine's N7. Can also cause crosslinking of DNA.
- Nitrogen Mustards: Melphalan, cyclophosphamide, ifosfamide, chlorambucil, estramustine, carmustine, lomustine, nimustine, streptozocin.
- Nitrosoureas: Carmustine, Lomustine, Nimustine
- Platinum Drugs: Carboplatin, cisplatin, oxaliplatin. Alkylate the O6 of guanine, causing crosslinking and DNA damage. Crosslinks DNA by attaching to guanine's N7.
- Miscellaneous: Busulfan, procarbazine. Busulfan removes a mesylate group to form R-CH2, alkylates N7 of guanine, and causes DNA crosslinking. Procarbazine forms an ion, cation, and alkylates at the O6, potentially inhibiting protein, RNA, and DNA synthesis.
Antimetabolites
- Pyrimidine or Purine Antimetabolites: Interfere with normal cellular metabolites by inhibiting the conversion of cytidylic acid to 2-deoxycytidylic acid, which is effective during S-phase.
- 5-fluorouracil, capecitabine, gemcitabine, cytarabine, azacitidine
Antimitotics
- Taxanes: Bind to free tubulin to form stable microtubules, stopping microtubule disassembly, essential for cell division.
- Paclitaxel, Docetaxel
Targeted Therapy Agents
- Tyrosine Kinase Inhibitors: Inhibit BCR, ABL, used for cancer cell proliferation, movement, and apoptosis avoidance. Inhibit EPFR for DNA synthesis, proliferation, migration, and survival.
- Imatinib, Gefitinib
- Monoclonal Antibodies: Inhibits HER2 to prevent abnormal cell growth, survival, and proliferation, impacting its dimerization.
- Trastuzumab, Pertuzumab
Antitumor Antibiotics
- Vinca Alkaloids: Bind to tubulin preventing microtubule formation thus preventing cell division.
- Vinblastine, vincristine, vindesine, vinorelbine
- Anthracyclines: Insert themselves between base pairs of DNA.
- Daunorubicin, doxorubicin, epirubicin, idarubicin, mitoxantrone
DNA Repair Enzyme Inhibitors
- Inhibit DNA repair in cancer cells to cause cancer cell death.
- Olaparib, rucaparib, niraparib, iniparib, talazoparib
Apoptosis-Inducing Agents
- Induce apoptosis (programmed cell death).
- Bortezomib
Angiogenesis Inhibitors
- Inhibit angiogenesis (formation of blood vessels), depriving tumors of essential nutrients.
- Bevacizumab
Multiple Targeted Tyrosine Kinase Inhibitors
- Inhibit various tyrosine kinases, impacting numerous pathways.
- Sunitinib
Immunotherapies
- PD-1 Inhibitors: Inhibit PD-1, reducing the ability of the tumor cell to evade killing.
- Pembrolizumab, Nivolumab, Cemiplimab, Atezolizumab
- PD-L1 Inhibitors: Inhibit PD-L1 and the ability of the tumor cells to avoid killing.
- Avelumab, Durvalumab
Hormonal Therapies
- Tamoxifen: Blocks estrogen receptor (ER), preventing hormone binding and cancer growth.
