Common NameFredericamycin A
DescriptionFredericamycin A is a natural antibiotic belonging to the chemical class of spirocyclic hydroquinones. Its unique structure features a quasi-symmetrical spirocyclic framework, which presents challenges for chemical synthesis (PMID:40271023 ). The total synthesis of fredericamycin A has been achieved through various innovative methods, including the assembly of multicyclic isoquinoline scaffolds from pyridines (PMID:34377413 ) and the use of stereoselective reactions (PMID:33522232 ). Notably, the first asymmetric synthesis of fredericamycin A has been reported alongside the synthesis of several other anthracycline antibiotics (PMID:32999145 ). Furthermore, synthetic approaches to its ABCD ring system have employed Claisen rearrangement and ring-closing metathesis as key steps (PMID:31656883 ). The production of fredericamycin A has also been enhanced in the deep-sea-derived Streptomyces somaliensis SCSIO ZH66 through ribosome engineering and response surface methodology, which activated its cryptic gene cluster (PMID:25927229 ). This compound is structurally related to fredericamycin C2 and is considered a potent lead in anticancer drug development (PMID:32481766 ).
