Anthracyclines and angucyclines both have a tetracyclic core. Now, I need to classify urdamycinone B, fridamycin A, fridamycin G, and dehydroxyaquayamycin as anthracycline or angucycline. Both urdamycinone B and dehydroxyaquayamycin contain benz[a]anthraquinone core. While fridamycin A and G both contain anthraquinone core. I have classified urdamycinone B and dehydroxyaquayamycin as anthracyclines. And fridamycin A and G as angucyclines.
Did I classify the compounds correctly? And what are the differences between anthracyclines and angucyclines in terms of their sources and structures?
