Descripción

General description

Antibiotic that specifically inhibits DNA-dependent bacterial RNA polymerase by forming an inactive complex with RNA polymerase. Does not affect mammalian RNA polymerase. Inhibits transcription by preventing the initial transcription complex from entering the elongation mode.

Biochem/physiol Actions

Primary Target
DNA-dependent RNA polymerase in bacteria

Preparation Note

Following reconstitution, aliquot and freeze (-20°C). DMSO stock solutions are stable for up to 2 months at -20°C.
