acids can form hydrogen bonds. Consequently, we have designed ω-hydroxy fatty acid-containing glycolipid derivatives of the prototypical CD1d ligand α-GalCer. The potency of the ω-hydroxy analogues of the proper length is comparable to that of α-GalCer. We propose, based on the biological results and molecular modeling studies, that a hydrogen bonding interaction is involved between the ω-hydroxy group
CD1d 分子识别具有直链脂肪酸部分的糖脂抗原。尽管 CD1d 结合沟中的大部分残基是疏水的,但一些氨基酸可以形成氢键。因此,我们设计了原型 CD1d 配体 α-GalCer 的含 ω-羟基脂肪酸的糖脂衍生物。适当长度的 ω-羟基类似物的效力与 α-GalCer 的效力相当。我们建议,基于生物学结果和分子模型研究,ω-羟基与疏水结合沟中的极性氨基酸残基之间存在氢键相互作用。
