of the alkylation subunit within the three subunit arrangement (sandwiched vs extended and reversed analogues) indicates that it not only has a profound impact on the rate and efficiency of DNA alkylation but also controls and establishes the DNA alkylation selectivity as well, where both enantiomers of such sandwiched agents alkylate the same adenine sites exhibiting the same DNA alkylation selectivity
对 yatakemycin 左右亚基及其取代基的影响进行了系统检查,并对其独特的三个亚基排列(夹心与扩展和反向类似物)进行了研究。约的检查。制备的 50 个类似物表明,在矢车霉素三亚基结构中,亚基取代基相对不重要,独特的夹心排列显着提高了其 DNA 烷基化反应的速率和效率。这增强了 yatakemycin 及其类似物的细胞毒活性,克服了该系列中更传统的化合物(CC-1065,duocarmycins)通常观察到的局限性。而且,
