text: The dynemicins are a sub-family of enediynes whose members are organic compounds generated in Micromonospora chersina. Dynemicin A was the first member of this sub-family to be discovered. It was isolated from M. chersina in a soil sample taken from the state of Gujarat in India. Dynemicins are violet in color because they contain anthraquinone as a variable group attached to the enediyne core. Dynemycins have demonstrated strong antitumor activity against leukemia and melanoma cells.
