Cyclic Dipeptides Mediating Quorum Sensing and Their Biological Effects in Hypsizygus Marmoreus
Biomolecules, 2020 A novel quorum sensing (QS) system was discovered in Serratia odorifera, the symbiotic bacterium of Hypsizygus marmoreus. This system uses cyclo(Pro-Phe), cyclo(Pro-Tyr), cyclo(Pro-Val), cyclo(Pro-Leu), cyclo(Tyr-Leu), and cyclo(Tyr-Ile) as autoinducers.

Nojirimycin Based 2,5-Diketopiperazines
, 2019 2,5-Diketopiperazines were prepared and characterized where one of the amino acids is (2S,3R,4R,5S)-3,4,5-trihydroxypipecolic acid. The protected pipecolic acid was synthesized from a selectively protected deoxynojirimycin derivative. The ring closure to
