AntiMetabolites
CCS in S phase Goal is to disrupt DNA precursor production/synth

5-fluororuracil Capecitabine
Prodrog antimetablite CCS 5-flourouracil: DHPD converts to FdUMP inhibiting dna synth of thymine (thymineless death) and FUTP (inhibiting RNA processing and translation). Patients lacking DHPD get severe tox. Capecitaine: Fluoropyridine prodrug. SEs: Hand foot syndrome
Cytarabine Gemcitabine
Deoxycitidine Pyrimide Analog Antimetabolite (CCS) Cytarabine: RAPID CLEARANCE–continous IV infusion, hematological malignancies (AML first line drug)–makes sense since maintain a high concentration in blood but not anywhere else dt clearance. Gemcitiabine: Inhibits RBR thus inhibiting DNA pol, DNA syth/repair, causing Chain term. BROAD cancer tx, SEs: Neutropenia and Renal Microangiopathy.
6-mercaptopurine Cladribine 6-thiopurine Fludarabine
Purine antagonist type antimetabolite (CCS) 6-mercaptopurine–metabolixed by HPRT. SEs: Def of TPMT causes toxicity which is exacerbated with Allopurinol Cladribine: Immunosupression of CD4/8 T-cells
Vinblastine Vincristine
Vinca Alkyloid (CCS) Microtubule destabilizers arresting cell in mitosis (no spindle assembly). Vinblastine–vessicant (BLAST forms BLISTERS, and used for BONE marrow)
Vincristine: Neurotox w/ peripheral neuropathy, SIADH, ANS dysfunction
Paclitaxel Abraxane Docetaxel Ixebepilone
Taxane class (CCS) Microtbuule stabilizers, cleared by Cyp 450s Paclitaxel–breast, ovarian (solid tumors) SEs: Hypersensitivy and neurotoxicities Abraxane–Paclitaxel with albumin to prevent hypersensitivity Ixebepilone: Nontaxane. Binds Beta-tubulin subunits causing stabilization
Etoposide
Teniposide
Epipodophylotoxins CCS Etoposide: Inhbits Topoisomerase 2**. SEs: HOTN, myelosupresion, alopecia, nausea, vomitiging
