  摘要：

  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。

  摘要：

  In a search for compounds related to flavoneacetic acid with activity against solid tumors, a series of methyl-, methoxy-, chloro-, nitro-, and hydroxy-substituted xanthenone-4-acetic acids have been synthesized and evaluated against subcutaneously implanted colon adenocarcinoma 38 in vivo, using a short-term histology assay as a primary screening system. A major goal of this work was to identify compounds with similar profiles of activity to that of flavoneacetic acid but of higher potency. The level of activity of the compounds appeared to depend more on the nature of the substituent than its positioning, in the order Cl greater than Me, OMe greater than NO2, OH. However, the potency of the compounds was related much more to the position rather than the nature of the substitution, with 5-substituted compounds being clearly the most dose potent. 5-Methylxanthenone-4-acetic acid has a similar level of activity to that of flavoneacetic acid in the test systems employed but is more than 7-fold as dose potent.

  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
