Abstract
The present invention concerns an antibiotic substance of microbial origin, arbitrarily denominated GE23077 complex and the individual factors that constitute it, namely GE23077 factor A1, GE23077 factor A2, GE23077 factor B1 and GE23077 factor B2, a mixture of said factors in any proportion, the pharmaceutically acceptable salts and compositions thereof, and their use as an antibacterial agent with a selective inhibitory activity against E. coli RNA polymerase. Another object of the present invention is a process for preparing GE23077 complex, namely GE23077 factor A1, GE23077 factor A2, GE23077 factor B1 and GE23077 factor B2, a mixture of said factors in any proportion, hereinafter reported as GE23077 compounds.
