Chemical ecology and bioactivity of triterpene glycosides from the sea cucumber Psolus patagonicus (Dendrochirotida: Psolidae)
Information on the chemical ecology and bioactivity of chemical compounds present in the sea cucumber Psolus patagonicus is provided through an interdisciplinary approach. The specimens studied were collected from two different and very distant sampling localities: Bridges Islands (Beagle Channel, U...
