    • Amphotericin B (or other hydrophobic compound) is encapsulated in a deaggregated form in micelles of monomethoxy poly(ethylene glycol)-phospholipid (as specifically exemplified, the phospholipid is 1,2 di-stearoyl-sn-glycero-3-phosphatidyl ethanolamine) formed by solvent evaporation. Advantageously, the hydration of the dried drug-polymer film is carried at between about 25 °C and about 80 °C. The micelles can be reconstituted with the Amphotericin B (or other hydrophobic compound) in a deaggregated state and safely used in therapy for fungal infections of humans or animals, especially for systemic fungal infections, or other desired application. The polyene micellar formulations described herein are reduced in toxicity as compared with those polyene formulations in which there is significant occurrence of aggregated polyenes.
    • 将两性霉素B(或其他疏水性化合物)以解聚集形式包封在单甲氧基聚(乙二醇) - 磷脂胶束中(如特别例示的,磷脂为1,2-二硬脂酰-sn- 甘油基-3-磷脂酰乙醇胺)通过溶剂蒸发形成。 有利地,干燥的药物 - 聚合物膜的水合在约25℃和约80℃之间进行。 胶束可以用解聚状态的两性霉素B(或其他疏水性化合物)重构,并且安全地用于人或动物的真菌感染的治疗,特别是用于全身性真菌感染或其他期望的应用。 与其中存在显着聚集的多烯的那些多烯配制剂相比,本文描述的多烯胶束配制剂的毒性降低。

    • Provided herein are mutant strains of Neisseria meningitidis which produce Kdo-free lipid A as well as the Kdo-free lipid A molecules and immunogenic compositions containing such Kdo-free lipid A molecules from a Neisseria strain containing a genetically stable mutation which inactivates a gene selected from the group consisting of genes encoding arabinose-5-phosphate isomerase, CMP-Kdo synthetase and CMP-Kdo transferase. N. meningitidis NMB206 is a specifically exemplified strain which harbors a stable insertion mutation in the gene ( kpsF ) encoding A5P isomerase; strain NMB-249 is a specifically exemplified strain with a stable insertion mutation in the gene ( kdtA ) encoding CMP-Kdo synthetase, and strain NMB259 is specifically exemplified strain with a stable insertion mutation in the gene ( kdsB ) encoding CMP-Kdo transferase. Also provided by the present invention are methods for the production of Lipid A free of 3-keto-3-deoxyoctanoic acid using these genetically stable N. meningitidis mutants. Also describes is pYT250, a plasmid functional in neisseriae and in enterics such as Escherichia coli .
    • 本文提供脑膜炎奈瑟球菌的突变菌株,其产生不含Kdo的脂质A以及不含Kdo的脂质A分子和含有来自包含基因稳定突变的不含Kdo的脂质A分子的免疫脂质A分子的灭活组合,所述突变使所选择的基因失活 来自编码阿拉伯糖-5-磷酸异构酶,CMP-Kdo合成酶和CMP-Kdo转移酶的基因组。 脑膜炎奈瑟球菌NMB206是在编码A5P异构酶的基因(kpsF)中具有稳定插入突变的特异性例证菌株; 菌株NMB-249是编码CMP-Kdo合成酶的基因(kdtA)中具有稳定插入突变的特异性例证菌株,并且菌株NMB259具体示例是在编码CMP-Kdo转移酶的基因(kdsB)中具有稳定插入突变的菌株。 本发明还提供了使用这些遗传稳定的脑膜炎奈瑟菌突变体生产不含3-酮-3-脱氧辛酸的脂质A的方法。 还描述了pYT250,在奈瑟氏球菌和肠道中如大肠杆菌中功能的质粒。
