acids are a class of antitumor agents effective against the mouse colon adenocarcinoma 38 in vivo. Within this class, 5-substituents on the xanthenone are known to enhance potency. To extend structure-activity relationships for the class, a series of derivatives bearing a wide variety of substituents at the 5-position have been prepared and evaluated. The results suggest that activity correlates better
9-氧代氧杂环丁烷-4-乙酸是一类在体内有效对抗小鼠结肠腺癌38的抗肿瘤药。在这一类中,已知黄嘌呤酮上的5位取代基可增强效力。为了扩展该类别的结构-活性关系,已经制备和评估了一系列在5-位带有多种取代基的衍生物。结果表明,活性与取代基的亲脂性更好地相关,而不是与其电子特性相关。通常,亲脂性取代基产生更多的活性化合物,但是这种取代基可能有尺寸限制。5-甲基衍生物是所研究类似物中剂量最高的。
