  Structure-Activity Relationship of .alpha.-Galactosylceramides against B16-Bearing Mice

  摘要：

  Agelasphin-9b, (2S,3S,4R)-1-O-(alpha-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-(alpha-D-galactopyranosyl)2-(N-hexacosanoylamino)-1,3,4-octadecanetriol, was selected as a candidate for clinical application.

  To confirm their structures and to assess the pheromonal activity, novel ceramides, possible sex pheromones of the hair crab Erimacrus isenbeckii, were synthesized from D-galactose. The synthetic ceramides were identical with the natural ceramides.
• Agelasphins, novel antitumor and immunostimulatory cerebrosides from the marine sponge Agelas mauritianus

  New glycosphingolipids, named agelasphins (1-8), have been isolated by antitumor and immunostimulatory bioassay-guided purification from an extract of a marine sponge, Agelas mauritianus. Strongly active agents in agelasphins had characteristic ol-galactosylceramide structures, the isolation of which from natural products has not previously been reported. The absolute configurations of agelasphins were elucidated by the total synthesis.

  RCAI-17, 22, 24-26, 29, 31, 34-36, 38-40, and 88, the analogs of KRN7000 (1) with a sulfonamide linkage instead of an amide bond, were synthesized to examine their bioactivity for mouse natural killer (NK) T cells. RCAI-17, 22, 24-26, 29, 31, 34-36, and 88 are the aromatic sulfonamide analogs, while RCAI-39 and 40 are the aliphatic ones. RCAI-38 is a C-galactoside analog of RCAI-26, which is the p-toluenesulfonamide analog of KRN7000. According to their bioassay, these sulfonamide analogs were shown to be the stimulants of mouse NKT cells to induce the production of Th2-biased cytokines in vitro, while RCAI-38 did not induce any cytokine production.
