Dideoxyverticillin A (+)-11,11’-dideoxyverticillin A is a complex epipolythiodioxopiperazine [1] initially isolated from the marine fungus Penicillium sp. in 1999 [2] 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]
