B3-042 Anti Cancer Drugs Flashcards
CCNS alkylating agents
cyclophosphamide
mechlorethamine
cis-platin
Mechanism: transfering an alkyl group over to DNA. Blocks access to DNA by cross linking.
CCNS alkylating agents
can lead to secondary malignancy due to DNA damage induced
CCNS alkylating agents
adds alkyl group to guanine
prodrug, metabolized by CYP450
cyclophosphamide
clinical use for multiple myeloma, lymphoma, leukemia, ovarian/breast cancer, small cell lung cancer, neuroblastoma, sarcoma
cyclophosphamide
delayed adverse effect is sterile hemorrhagic cystitis (hematuria/excessive voiding)
cyclophosphamide
produces acrolein-toxic metabolite
cyclophosphamide
mechanism of resistance for CCNS alkylating agents
impermeable to drug
pump drug out
alternate targets for drug (GSH)
increased DNA repair
no apoptosis
first ever alkylating agent, Hodgkins lymphoma
mechlorethamine
cross links DNA with platinum
cis-platin
cisplatin with less toxicity but more myelosuppression
carboplatin
cisplatin with less renal but more neurotoxicity
oxaliplatin
aromatase inhibitors that decreases estrogen synthesis [2]
anastrozole, letrozole
hormonal agents
anastrozole
letrozole
flutamide
hydrocortisone
prednisone
tamoxifen
androgen receptor antagonist
flutamide
adrenocorticosteroids [2]
suppress proliferation of immune cells
hydrocortisone
prednisone
selective estrogen receptor anatagonist
tomoxifen
used for breast cancer in post menopausal women
ER+ primary and metastatic cancers [2]
anastrozole
letrozole
used for metastatic prostate cancer
flutamide
hormonal agents [2] used for leukema/lymphoma
hydrocortisone
prednisone
hormonal agent used for breast cancer
tamoxifen
adverse effects: anastrozole
nausea, headache, hot flashes
adverse effects: flutamide
hepatic effects
adverse effects: hydrocortisone/prednisone
elevated fasting glucose
fluid retention
immunosuppression
diabetes
hormonal agents: CYP2D6 activation
tamoxifen
CCS Topoisomerase inhibitors
etoposide
irinotecan
inhibits DNA topoisomerase II
etoposide
inhibits DNA Topoisomerase I, pro-drug
irinotecan
topoisomerase inhibitor for colon cancer
irinotecan
topoisomerase inhibitor for testicular, small cell lung, leukemia, lymphoma
etoposide
irinotecan is metabolized by UGT1A1. A deficiency can cause
increased toxicity, leading to
Crigler-Najjar, Gilbert’s, hyperbilirubinemia
checkpoint inhibitors
ipilimumab
nivolumab
atezolimumab
mAb against CTLA-4
ipilimumab
mAb against PD-1
nivolumab
mAb against PD-L1
atezolimumab
checkpoint inhibitor used for unresectable or metastatic melanoma
ipilimumab
checkpoint inhibitor used for melanoma, colon, HENT, hepatocellular, hodgkins, non-small cell lung, urothelial
nivolumab
adverse effects: ipilimumab
immune inflammatory response
