Entity of the month
Himastatin (CHEBI:190009), a natural product produced by the soil bacterium, Streptomyces himastatinicus, was first discovered in the 1990s. The compound is known for its antibiotic activity and when tested in animals, it was also found to have potent anticancer activity . The compound is a dimer that consists of two identical subunits (monomers) that are joined together by a bond that connects a six-carbon ring in one of the monomers to the identical ring in the other monomer thus forming a carbon-carbon bond that is critical for the compound's antimicrobial activity. In previous efforts to synthesize the compound, chemists tried to make the carbon-carbon bond first, using two simple subunits, and then added more complex functional groups onto the monomers .
