Dideoxyverticillin A, also known as (+)-11,11′-dideoxyverticillin A, is a complex epipolythiodioxopiperazine[1] initially isolated from the marine fungus Penicillium sp. in 1999.[2] It has also been found in the marine fungus Bionectriaceae,[3] and belongs to a class of naturally occurring 2,5-diketopiperazines.[4]
Dideoxyverticillin A potently inhibits the tyrosine kinase activity of the epidermal growth factor receptor (median inhibitory concentration = 0.14 nM), exhibits antiangiogenic activity, and has efficacy against several cancer cell lines.[4] Its reported anticancer mechanism is that it acts as a farnesyl transferase inhibitor. Dozens of semi-synthetic anticancer compounds have been made from dideoxyverticillin A. Dimeric derivatives are reported to have better anticancer activity.[5]
The enantioselective first total synthesis of (+)-11,11′-dideoxyverticillin A, the structure of which contains many sterically congested, contiguous stereogenic centers as well as acid- and base-labile and redox-sensitive functionality, was biosynthetically inspired and achieved with high levels of chemical sophistication.[6]
