  A new access to enantiomerically pure deoxy aminohexoses: Methyl 4-amino-4,6-dideoxygulopyranoside and epi-tolyposamine

  摘要：

  New efficient synthetic routes have been developed starting from the fully protected L-threonine derivative 1 for some deoxy-4-aminohexoses: methyl 4-amino-4,6-dideoxy gulopyranoside 2 and epi-tolyposamine 3. The title compounds were synthesized using an improved Horner-Emmons reaction of the threonine derived aldehyde 7. A new method for selective removal of the aminal protection is also reported.

  The synthesis and biological evaluation of ten Michael acceptors containing potential proteasome inhibitors are described. Cellular targets of azide containing inhibitors Ib and VIIIb were assessed in HEK293T and RAW264.7 cells by a two step labeling strategy, followed by biotin-pulldown, affinity purification, on-bead tryptic digestion and LC-MS2 identification. This strategy appears to be an attractive alternative to gel-based competition assays.

  描述了含有潜在蛋白酶体抑制剂的十个迈克尔受体的合成与生物学评价。通过两步标记策略在HEK293T和RAW264.7细胞中评估了含有叠氮基抑制剂Ib和VIIIb的细胞内靶点，随后进行生物素-牵拉、亲和纯化、在珠上胰蛋白酶消化和LC-MS2鉴定。该策略似乎是一个有吸引力的乳胶凝胶竞争性测定的替代方案。
