The previously described, biologically active 4- O -phosphono- d -glucosamine derivatives GLA-27, GLA-47, and GLA-60 (all related to bacterial lipid A) were converted into their respective conjugates with 3-deoxy- d - manno -2-octulosonic acid (KDO). The methyl and benzyl esters of [4,5,7,8-tetrakis- O -(chloroacetyl)-3-deoxy- d - manno -2-octulopyranosyl fluoride]onic acid and the corresponding glycosyl
摘要将先前描述的具有生物活性的4- O-膦酰基-d-葡萄糖胺衍生物GLA-27,GLA-47和GLA-60(均与细菌脂质A有关)转化为各自的具有3-deoxy-d-的共轭物。甘露-2-氨基磺酸(KDO)。通过从甲基开始,制备了[4,5,7,8-四-O-(氯乙酰基)-3-脱氧-d-甘露聚糖-2-辛基吡喃糖基氟]酸的甲基和苄基酯和相应的糖基溴化物。 2,4,5,7,8-戊基-O-乙酰基-3-脱氧-d-甘露糖-2-辛基吡喃磺酸酯,并与膦酰基-d-葡糖胺的适当保护的前体的O-6偶联。这产生了一系列完全取代的二糖,这些二糖通过O-去(氯乙酰基)化并依次氢解去除苄基,苄氧基甲基和苯基而进行转化,
