Enzymatic Synthesis of Novel Chiral Sulfoxides Employing Baeyer–Villiger Monooxygenases

Ana Rioz-Martínez, +4 more
- 01 Nov 2010 - 
TL;DR: Careful selection of the reaction conditions, starting sulfide, and biocatalyst can be used to achieve good to excellent enantiomeric excess values and valuable chiral synthons can be obtained by performing the reactions under mild and environmentally friendly conditions.

Fused xanthone derivatives as antiproliferative agents.

Nicole Pouli, +1 more
- 01 Jan 2009 - 
TL;DR: The furanoxanthone psorospermin is a highly promising isolated xanthone derivative exhibiting significant cytotoxicity through a novel mechanism of action, being an irreversible topoisomerase II poison and it was selected for further development as an antineoplastic agent.
