What is the biological effect of rifamycin?

Rifamycin is a group of antibiotics whose activity depends on its high affinity for prokaryotic RNA polymerase inhibiting bacterial DNA-dependent RNA synthesis (Calvori et al., 1965). Rifamycins can enter neutrophils and macrophages and then inhibit bacterial DNA-dependent RNA polymerase (www.amrls.cvm.msu.edu).
