  The isolation and synthesis of two novel N-acetyl glucosamine derivatives from Dictyostelium cellular slime molds which exhibit neurite outgrowth activity

  摘要：

  To clarify the diversity of secondary metabolites of Dictyostelium cellular slime molds and explore any biologically active substances which they may hold, constituents of two species were investigated. From a methanol extract or their fruit bodies, two novel acylated amino sugar were isolated, dictyoglucosamine A (1) from D. purpureum and dictyoglucosamine B (2) from D. discoideum. For further analysis, these compounds were then synthesized from N-aceyl-D-glucosamine. Biological evaluation of 1 and 2 shocked the induce neuronal differentiation of rat pheochromocytoma (PC-12) cells. (C) Elsevier Science Ltd. All rights reserved.
