Hp-s1 (1) which displays neuritogenic activity toward the rat pheochromocytoma cell line PC-12 cell in the presence of nervegrowthfactor (NGF) with an effect (34.0%) greater than that of the mammalian ganglioside GM 1 (25.4%), was accomplished by applying a chemoselective-activation glycosylation strategy. Moreover, we also demonstrate that the synthesized ganglioside 2 exhibited neuritogenic activity
A gift from the star: The title compound, which was identified in starfish, contains two sialic acid units and was constructed utilizing a sialic acid derivative as a pivotal precursor. The potentially difficult conjugation of the phytoceramide portion with the glycan portion was achieved through the glucosyl ceramide cassette approach.
