A multistep stereospecific synthesis of two novel pyrazole C-nucleosides 12 and 21 has been achieved starting from d-glucose, by utilizing the 2,5-anhydro-d-glucose ethylene acetal derivative 1 as a divergent intermediate. The C-nucleoside 12 was shown to be a moderate inhibitor of the in vitro growth of N2a and BHK 21 tumor cell lines, whereas 21 showed a moderate cytotoxic activity only against N2a
通过使用2,5-脱水-d-葡萄糖乙烯乙缩醛衍生物1作为发散中间体,已经从d-葡萄糖开始实现了两个新颖的吡唑C-核苷12和21的多步立体有择合成。所述Ç核苷12被证明是的N2a细胞和BHK 21肿瘤细胞系的体外生长的适度抑制,而21显示出适度的细胞毒性活性仅仅针对N2a细胞。
