Q

Describe the mechanism of action of the antimetabolites

A

antimetabolites interfere with DNA production and in the case of methotrexate and pralatrexate they do this by blocking dihydrofolate reductase which reduces the pool of reduced folate needed for cell replication

16
Q

Describe the mechanism of action for drugs that target CML specifically

A

these drugs bind to the ATP binding site of the BCR-ABL onco-protein stopping the protein from stimulating cell reproduction [blocks the tyrosine kinase activity]

17
Q

Name the chemo drugs classified as immune modulators

A
  • aldesleukin [IL-2]
  • axicavtagene ciloleucel
  • interferon
  • lenalidomide
  • pomalidomide
  • thalidomide
  • tisagenlecleucel
18
Q

Describe the mechanism of action of immune modulators

A

they modulate the immune system and are antiangiogenic

19
Q

Name the one drug that is a protein synthesis inhibitor targeting BCR-ABL protein in CML

A
  • Omacetaxine mepesuccinate
20
Q

Name the two drugs that consume cellular asparagine [this is bad because asparagine is essential for cell replication]

A
  • L-Asparaginase
  • Pegasrapinase
21
Q

Name the one chemo drug that is an antibiotic and describe how it works

A
  • Bleomycin
  • works by introducing DNA strand breaks [both single and double-stranded]
22
Q

Name the chemo drugs classified as differentiating agents

A
  • All-trans-retionic acid [Tretinoin]
  • arsenic trioxide
23
Q

Describe how differentiating agents work

A

They induce the differentiation of leukemia cells in APL by binding to retinoic acid receptors. They overcome the receptor changes and allow the genes necessary for maturation to be transcribed.

24
Q

A
  • Alemtuzumab [anti-CD52]
  • Blinatumomab [anti-CD19]
  • Brentuximab vedotin [anti-CD30]

    *
25
Q

Describe how the monoclonal antibodies work against lymphoma

A
  • monoclonal antibodies bind cells via CD20, CD19, or other proteins on B cells causing antibody-dependent and complement-dependent cytotoxic effects or linkage with an antineoplastic moiety linked to the monoclonal antibody
26
Q

Name the chemo drugs that are topoisomerase inhibitors and describe the mechanism of action

A
  • Etoposide
  • Teniposide
  • Topotecan
  • Irinotecan

MOA: block topoisomerase I or II. They result in single and double-strand breaks in the DNA.

27
Q

Name the one drug that is a ribonucleotide reductase inhibitor and describe it’s mechanism of action

A
  • Hydroxyurea

MOA: prevents conversion of ribonucleotides to deoxyribonucleotides, halting the cell cycle in G1/S phase

28
Q

Name the glucocorticosteriods and describe the mechanism of action

A
  • dexamethasone
  • methylprednisolone
  • prednisone

MOA: they are directly toxic to lymphocytes and induce cell death/apoptosis

29
Q

Name the drugs which are epigenetic modifiers of translated DNA

A
  • Belinostat
  • Panobinostat
  • Romidepsin
  • Vorinostat
30
Q

Describe the mechanism of action of epigenetic modifiers of translated DNA

A

block histone deactylase - histones are less compact and gene activation can take place

31
Q

Name the common therapies for acute myelogenous leukemia [AML]

A
  • Daunorubicin or idarubicin [anthracyclines]
  • cytosine arabinoside [pyrimidine analog]
32
Q

Name the common therapies for acute lymphocyte leukemia

A
  • prednisone [glucocorticosteroid]
  • vincristine [microtubule inhibitor]
  • asparaginase [consumes cellular asparagine]
  • daunorubicin [anthracycyline]
33
Q

Name the common therapies for Hodgkin’s Disease

A
  • Adriamycin [Doxorubicin]
  • Bleomycin [antibiotic - causes DNA strand breaks]
  • Vincristine [microtubule inhibitor]
  • Dacarbazine [alkylating agent - cross-link DNA]
