IUPAC Name: (2S,3R,4R,5R,6S)-2-[(2S,3R,4S,5S,6R)-2-[(2R,3R,4S,5R,6R)-4,5-dihydroxy-2-[[(1S,2R,4S,5R,8R,10S,13S,14R,17S,18R,19S,20R)-2-hydroxy-4,5,9,9,13,19,20-heptamethyl-24-oxahexacyclo[15.5.2.01,18.04,17.05,14.08,13]tetracos-15-en-10-yl]oxy]-6-methyloxan-3-yl]oxy-4,5-dihydroxy-6-(hydroxymethyl)oxan-3-yl]oxy-6-methyloxane-3,4,5-triol

Description: The molecule is a triterpenoid saponin that consists of urs-11-ene substituted by an epoxy group across positions 13 and 28, a hydroxy group at position 16 and a alpha-L-rhamnopyranosyl-(1->2)-beta-D-glucopyranosyl-(1->2)-beta-D-fucopyranosyloxy residue at position 3 (the 3beta,16alpha stereoisomer). Isolated from the fruits of Bupleurum rotundifolium, it exhibits antiproliferative activity against cancer cells. It has a role as an antineoplastic agent and a plant metabolite. It is a bridged compound, a cyclic ether, a hexacyclic triterpenoid, a trisaccharide derivative and a triterpenoid saponin. It derives from a hydride of an ursane.
