alpha-d-galactosyl ceramide, were synthesized to examine their bioactivity for mouse natural killer (NK) T cells to produce cytokines. RCAI-8, 9, 51, and 52 are the analogues with a pyrrolidine ring, and RCAI-18, 19, 49, and 50 are those with an azetidine ring. RCAI-18 was shown to be a potent inducer of cytokine production by mouse NKT cells, while RCAI-51 was a moderately active inducer.
合成了KRN7000的构象受限类似物,即α-d-半
乳糖基神经酰胺,以检查其对小鼠自然杀伤(NK)T细胞产生细胞因子的
生物活性。RCAI-8、9、51和52是带有
吡咯烷环的类似物,而RCAI-18、19、49和50是带有氮杂
环丁烷环的类似物。RCAI-18被证明是小鼠NKT细胞产生细胞因子的有效诱导剂,而RCAI-51是中等活性的诱导剂。
