An efficient synthesis of seven analogs of a naturally occurring saponin, indioside E, is described. The synthesis used a 3,4,6-O-protected D-galactopyranosyl thioglycoside as the key intermediate to enable regioselective glycosylation and one-pot multistep reactions. Antitumor activities of the synthetic saponins against a human hepatocellular carcinoma cell line BEL-7402 and a human breast adenocarcinoma cell line MCF-7 were evaluated by means of the CCK-8 assay. Analogs carrying trisaccharides with the D-xylopyranose in indioside E substituted with a D-ribopyranose and an L-arabinopyranose or with its diosgenin aglycon replaced with tigogenin exhibited similar antitumor activities as indioside E, but not other analogs.
