The core structure of pentaerythritol has been used as a replacement for one or both sugars in lipid A, leading to the generation of a series of lipid A analogs. These lipid A analogs may further differ from lipid A with respect to, e.g., the number, nature and location of negatively charged groups, and the number, nature and location of the lipid chains. The lipid A analogs may be lipid A agonists useful as immunostimulatory agents, or lipid A antagonists useful in the treatment of septic shock. In a like manner, a residue of pentaerythritylamine may be used as a replacement for an amino sugar residue in a carbohydrate ligand having a biological activity of interest, generating a series of ligand analogs. These are useful, e.g., as haptens, inhibitors of bacterial-host cell adhesion, etc.
季戊四醇的核心结构被用来替代脂质 A 中的一种或两种糖,从而产生了一系列脂质 A 类似物。这些脂质 A 类似物在带负电荷基团的数量、性质和位置,以及脂质链的数量、性质和位置等方面可能与脂质 A 有进一步的不同。脂质 A 类似物可以是用作免疫刺激剂的脂质 A 激动剂,也可以是用于治疗脓毒性休克的脂质 A 拮抗剂。同样,在具有生物活性的碳水化合物配体中,可使用季戊四醇胺残基替代氨基糖残基,从而产生一系列配体类似物。这些类似物可用作触杀剂、细菌-宿主细胞粘附抑制剂等。
