(32 cards)
Camptothecin
Stops Topo I, cancer treatment
Azidothymidine (AZT)
Treats HIV, blocks reverse transcriptase, no 3’ OH
Rifampin
Prokaryotic RNA Polimerase, inhibits initation of transcription, treats TB
Etoposide
Topo II, cancer
Streptomycin
An aminoglycoside
Prok, binds 30s ribosome, prevents assembly of translation proteins.
Genatamacin
An aminoglycoside
Binds ribosome 30s, prevents initiation
Tetracyclines
Minocycline, doxycycline, doxorubicin.
Binds 30s and blocks translation elongation by blocking the A site.
Cuprofloxacin and Nalidixic
Quinolone drugs
Blocks prok DNA gyrase
Acetazolamide
Carbonic anhydride inhibitor.
Inhibits water reabsorption in the kidney
Sodium Butyrate
Histone Deacetylase (acetylation)
Increases euk transcription
Chloramphenicol
Prokaryote pepsidal transferase, Inhibits peptide chain from moving from P site to A site
Puromycin
Analog to aminoacyl-tRNA makes AA chain fall off
Didanosine (ddl)
Viral reverse transcriptase
Nucleoside analog of adenosine
Lacks a 3’OH preventing elongation
Vidarabine
Adenosine arabinoside (araA) Reverse transcriptase inhibitor in treating Leukemia
2’OH creates steric hindrance preventing elongation.
Decitabine
DNA Anti methylation (prevents turn off of tumor suppressor genes)
In RNA: 5-Azacytidine
Cytidine nucleoside analog
Cytarabine: cytosine arabinoside (araC)
2’OH creates steric hindrance preventing elongation in DNA Pol
