Biological Activity
Bacterial[1]
PNU-176798 is an antimicrobial agent, with a minimum inhibitory concentration (MIC) of 1.4 μM for E. coli. PNU-176798 inhibits fMet-tRNA binding to the 70S ribosomes, with an IC50 of 32 μM. PNU-176798 also blocks translation, 70S initiation with IC50s of 0.53, and 32 μM, respectively. PNU-176798 inhibits peptidyl transferase (IC50, 40 μM), and the inhibition is more pronounced in the presence of elongation factor P (EF-P). PNU-176798 markedly inhibits the EF-G-mediated translocation of fMet-tRNA (IC50, 8 μM)[1].

Protocol
Binding of the f[35S]Met-tRNA to E. coli 70S ribosomes is conducted and the initiation reaction mixtures are prepared without initiation factors and contain 6 mM magnesium acetate [Mg(Ac)2], 0.08 μM AUG, 30 mM NH4Cl, 10 mM Tris (pH 7.4), and 20 pmol of 70S ribosomes in a final volume of 60 μL. The reaction mixtures are incubated for 15 min at 35°C, and the reactions are terminated by addition of cold buffer A, washed with buffer A, and counted by liquid scintillation[1].
