, p. 2176 - 2187 (2007/10/02)

Agelasphin-9b, (2S,3S,4R)-1-O-(α-D-galactopyranosyl)-16-methyl-2-[N- ((R)-2-hydroxytetracosanoyl)-amino]-1,3,4-heptadecanetriol, is a potent antitumor agent isolated from the marine sponge Agelas mauritianus. Various analogues of agelasphin-9b (a lead compound) were synthesized, and the relationship between their structures and biological activities was examined using several assay systems. From the results, KRN7000, (2S,3S,4R)-1-O-(α- D-galactopyranosyl)-2-(N-hexacosanoylamino)-1,3,4-octadecanetriol, was selected as a candidate for clinical application.
