synthesized. The antileukemic activities of these compounds were measured by MTT (3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide) assay in human leukemia HL-60 cells. N-(R)- and N-(S)-Lactylsphingosine displayed higher activities than N-acetylsphingosine (C2-ceramide, a well-known apoptosis inducer), and their dihydrosphingosine derivatives had slight activities.
合成了N-(R)-和N-(S)-鞘氨醇鞘氨醇及其相应的二氢鞘氨醇衍生物。通过MTT(3-(4,5-二甲基-2-噻唑基)-2,5-二苯基-2H-溴化四唑鎓)测定在人白血病HL-60细胞中这些化合物的抗白血病活性。N-(R)-和N-(S)-乳糖基鞘氨醇比N-乙酰基鞘氨醇(C2-神经酰胺,一种著名的细胞凋亡诱导剂)具有更高的活性,并且它们的二氢鞘氨醇衍生物具有轻微的活性。
