Twenty-six 5-azacytidine analogues have been synthesized, including 4-amino- 6-alkyl-1-pyranosyl/ribofuranosyl-1,3,5-triazin-2(1H)-ones 1a-j, 6-amino-4-alkyl/aryl-1- pyranosyl/ribofuranosyl-1,3,5-triazin-2(1H)-ones 2a-f and 4-amino-6-alkyl-1,3,5-triazin-2- yl-1-thio-pyranosides/ribofuranosides 3a-j. The antiproliferative activities of these synthetic analogues were investigated in human leukemia HL-60 cells. Ribofuranosyl Snucleoside 3a, a bioisostere of 5-azacytidine, had a similar antiproliferative ability as that of the latter. Introduction of a methyl at the 6 position of 5-azacytidine and/or replacement of the ribofuranosyl moiety with pyranosyl sugars or disaccharides significantly decreased the antiproliferative activities of the 5-azacytidine derivatives. Several compounds with the replacement of pyranosyl sugars enhanced all-trans retinoic acid-induced differentiation ability in human leukemia HL-60 cells.
合成了二十六种5-氮杂胞苷类似物,包括4-氨基-6-烷基-1-吡喃糖基/呋喃糖基-1,3,5-三嗪-2(1H)-酮1a-j、6-氨基-4-烷基/芳基-1-吡喃糖基/呋喃糖基-1,3,5-三嗪-2(1H)-酮2a-f和4-氨基-6-烷基-1,3,5-三嗪-2-基-1-硫代吡喃糖基/呋喃糖基3a-j。研究了这些合成类似物在人白血病HL-60细胞中的抗增殖活性。呋喃糖基S核苷3a作为5-氮杂胞苷的生物等排体,具有与后者类似的抗增殖能力。在5-氮杂胞苷的6位引入甲基和/或用吡喃糖基糖或二糖取代呋喃糖基部分显著降低了5-氮杂胞苷衍生物的抗增殖活性。一些用吡喃糖基糖取代的化合物增强了全反式维甲酸诱导的人白血病HL-60细胞的分化能力。
