Enantiodivergent formal synthesis of (+)- and (−)-muricatacins from d-xylose has been accomplished through utilization of the latent plane of symmetry present in the starting monosaccharide. This approach was extended to the preparation of two novel (+)- and (−)-muricatacin 7-oxa analogs (2 and ent-2, respectively), which showed in vitro antitumor activity toward some human malignant cells. The analog
通过利用存在于起始单糖中的对称性潜平面,已完成了由d-木糖对映体形式的(+)-和(-)-穆里卡他星的对映体形式合成。该方法扩展到制备两种新颖的(+)-和(-)-多卡他霉素7-oxa类似物(分别为2和ent - 2),它们显示出对某些人类恶性细胞的体外抗肿瘤活性。类似物ent - 2对K562细胞系显示出强大的抗增殖活性,效力比标准细胞毒剂阿霉素高36倍。化合物2然而,它对HL-60细胞显示出强大的细胞毒活性,相对于参比化合物,其效力高17倍以上。
