Cinerascensosides A and B, Two New Cytotoxic Sulfated Saponins From the Sea Cucumber Holothuria cinerascens
Two new cytotoxic sulfated compounds, cinerascensosides A and B (1 and 2), alongside three described triterpene glycosides, holothurins A (3), B (4), and B3 (5), were separated from the sea cucumber Holothuria cinerascens. Their structures and absolute configurations were established through extensive spectroscopic ana...
