The syntheses of novel tetraacetylsialyl- and sialyl-(α2-6)-D-glucosamine-4-phosphate analogues of lipid A containing sialic acid in place of 3-deoxy-D-mannno-2-octulosonic acid (KDO) are described. Preliminary examination of the biological activity revealed that two synthetic disaccharides possessed weak mitogenic activities.
本文描述了脂A的新型四乙酰唾液酸和唾液酸(α2-6)-D-葡萄糖胺-4-磷酸类似物的合成,其中唾液酸取代了3-脱氧-D-甘露-2-辛酮糖醛酸(KDO)。对生物活性的初步检查表明,两种合成的二糖具有微弱的促有丝分裂活性。
