A series of 4-deoxypyrido[1',2':1,2]imidazo[5,4-c]rifamycinSVderivatives (6-11) were prepared that demonstrated high antibacterial activity suitable for an intestinal disinfectant. These compounds are zwitterionic in nature and are poorly absorbed through the gastroenteric tract but maintain the ability to cross the bacterial cell wall. X-ray crystallographic data are presented to demonstrate the
