(-)-Jorumycin and its 15 C-22 analogues were prepared employing L-tyrosine as the chiral starting material via 21 steps. These analogues, along with (-)-jorumycin itself, were evaluated in vitro for cytotoxicity against HCT-8, BEL-7402, Ketr3, A2780, MCF-7, A549, BGC-823, Hela, HELF, and KB cells. The IC50 values of the cytotoxicity of most of these analogs were at the level of nM, which was similar to that of (-)-jorumycin. Among these analogs including (-)-jorumycin, hippuric acid ester derivative 23 exhibited the most potent and broad-spectrum cytotoxic activity against the ten cell lines with an average IC50 of 2.12 nM.

(-)-Jorumycin及其15C-22衍生物通过21步合成路线,利用L-酪氨酸作为手性起始材料制备而成。这些类似物,连同(-)-Jorumycin本身,在体外对HCT-8、BEL-7402、Ketr3、A2780、MCF-7、A549、BGC-823、Hela、HELF和KB细胞进行了细胞毒性评价。大部分类似物的细胞毒性IC50值均在nM水平,与(-)-Jorumycin相当。在这些类似物(包括(-)-Jorumycin)中,衍生物23对10种癌细胞显示出最显著和广谱的细胞毒性,平均IC50值为2.12nM。版权(C)2012 Elsevier Ltd. 所有权利保留。
