Total synthesis, isolation, surfactant properties, and biological evaluation of ananatosides and related macrodilactone-containing rhamnolipids.

Rhamnolipids are a specific class of microbial surfactants, which hold great biotechnological and therapeutic potential. However, their exploitation at the industrial level is hampered because they are mainly produced by the opportunistic pathogen . The non-human pathogenic bacterium is an alternative producer of rhamnolipid-like metabolites containing glucose instead of rhamnose residues.
