Cytotoxic drugs Flashcards
Cyclophosphamide MOA
alkylating agent - causes cross-linking in DNA
Cyclophosphamide adverse effects
haemorrhagic cystitis
myelosuppression
transitional cell carcinoma
Bleomycin MOA
degrades preformed DNA
Bleomycin adverse effects
lung fibrosis
Anthracyclines (eg. doxorubicin) MOA
stabilises DNA topoisomerase 2 complex
inhibits DNA and RNA synthesis
Anthracyclines (eg. doxorubicin) adverse effects
cardiomyopathy
Methotrexate MOA
inhibits dihydrofolate reductase and thymidylate synthesis
Methotrexate adverse effects
myelosuppression
mucositis
liver fibrosis
lung fibrosis
Fluorouracil MOA
pyrimidine analogue inducing cell cycle arrest and apoptosis by blocking thymidylate synthase (works during S phase)
Fluorouracil adverse effects
myelosuppression
mucositis
dermatitis
6-mercaptopurine MOA
purine analogue that is activated by HGPRTase, decreasing purine synthesis
6-mercaptopurine adverse effects
myelosuppression
Cytarabine MOA
pyrimidine antagonist
interferes with DNA synthesis specifically at S phase of cell cycle and inhibits DNA polymerase
Cytarabine adverse effects
myelosuppression
ataxia
