the control of several types of immune response. As an active glycolipid antigen having α-galactosyl ceramide core structure, KRN7000 showed promising immunostimulation activity and was selected as an anticancer drug candidate for further clinical application. In this report, three new KRN7000 structural analogues were designed and synthesized, in which the ring oxygen of the galactopyranose residue
NKT细胞是识别CD1d分子呈递的糖脂抗原的T细胞的独特子集,被认为可产生Th1和Th2 T细胞的关键细胞因子,因此参与了几种类型的免疫应答的控制。作为具有α-半乳糖基神经酰胺核心结构的活性糖脂抗原,KRN7000显示出有希望的免疫刺激活性,并被选作进一步临床应用的抗癌药物。在本报告中,设计并合成了三个新的KRN7000结构类似物,其中吡喃半乳糖残基的环氧被硫原子以及脂质链上的变异所取代。在体内和体外评估了它们刺激小鼠NKT细胞产生IFN-γ和IL-4的能力。
