考點:抗癌藥物Cancer Chemotherapy/機轉配對(參考資料:Katzung & Trevor's Pharmacology Examination and Board)
- Podophyllotoxins類:Etoposide、Teniposide
- 機轉說明:抑制Topoisomerase II造成DNA damage
- Camptothecins類:Irinotecan
- 藥理機制:抑制Topoisomerase I造成DNA damage
- Antimetabolites類:Pemetrexed
- 干擾葉酸代謝,如抑制胸苷酸合成酶(thymidylate synthase)、二氫葉酸還原酶(DHFR)
- Vinca alkaloids(長春花生物鹼)類:Vinorelbine、Vinblastine、Vincristine
- Tubulin(微管蛋白)的結合以阻斷微管聚合,干擾細胞有絲分裂(mitosis)
