1

Antimetabolites. Antimetabolites are ___ and ___ analogs and inhibit DNA synthesis. These are ___ cell cycle specific.

Antimetabolites are PURINE and PYRIMIDINE analogs and inhibit DNA synthesis. These are HIGHLY cell cycle specific.

2

Antimetabolites. Methotrexate is a ___ acid analog and inhibits DHFR. As a result, the metabolically active form of folate, ___, is not generated and conversion of dUMP to dTMP cannot occur.

Methotrexate is a FOLIC acid analog and inhibits DHFR. As a result, the metabolically active form of folate, MTHF, is not generated and conversion of dUMP to dTMP cannot occur.

3

Antimetabolites. 5-Flurouracil inhibits thymidylate synthase and prevents the conversion of ___ to ___.

5-Flurouracil inhibits thymidylate synthase and prevents the conversion of dUMP to dTMP.

4

Antimetabolites. Hydroxyurea inhibits ribonucleotide reductase and inhibits conversion of ___ to ___.

Hydroxyurea inhibits ribonucleotide reductase and inhibits the conversion of dUMP to dTMP.

5

Taxanes. Taxane drugs bind to microtubules and inhibit their ___ into tubulin. This prevents the cell from completing mitosis.

Taxane drugs bind to microtubules and inhibit their DEPOLYMERIZATION into tubulin. This prevents the cell from completing mitosis and dividing into two daughter cells.

Binds to TUBULIN and prevents cells from making the MITOTIC spindle.

10

Vinca Alkaloids. Vinblastine and Vincristine are given ___. If administered intrathecally, ___ occurs.

Vinblastine and Vincristine are given IV. If administered intrathecally, DEATH occurs.

11

Vinca Alkaloids. ___ is associated with neurotoxicity. ___ is associated with bone marrow suppression.

VINCRISTINE is associated with neurotoxicity. VINBLASTINE is associated with bone marrow suppression.

12

Etoposide blocks the G1 and S2 phase of the cell cycle. Used primarily for TESTICULAR cancer that hasn't responded to other treatment plans. HYPOTENSION is a common side effect.

14

Antitumor antibiotics. These are derived from ___ species and cause ___ necrosis.

These are derived from STREPTOMYCES species and cause TISSUE necrosis.

15

These medications are developed from MUSTARD base and attach an alkyl group to the number seven nitrogen atom of the PURINE ring.

17

Alkylating agents. Form ___ bonds to DNA. Specifically, the __ residue is attacked.

Form COVALENT bonds to DNA. Specifically, the GUANINE residue is attacked.

18

Alkylating agents. Cyclophosphamide is metabolized by the ___ system into aldophoshamide.
