Pseudouridimycin TFA
Pseudouridimycin (PUM) TFA is an antibiotic that selectively inhibits bacterial RNA polymerase (RNAP), with an IC50 of about 0.1 μM and MICs of 4-6 μg/mL. Pseudouridimycin TFA is a C-nucleoside analogue that's effective against both Gram-negative and Gram-positive bacteria. Pseudouridimycin TFA inhibits bacterial growth in vitro and shows activity in a mouse model of purulent streptococcal peritonitis.

Biological Activity
|
RNA Polymerase |
Pseudouridimycin (PUM) TFA is selective because of its side chain that binds in a region that is conserved in bacterial RNA polymerases but not in humans. In vitro bactericidal activity is reported for Pseudouridimycin TFA against drug-sensitive, drug-resistant, and multidrug-resistant Streptococcus species[1].
