  潜在的抗肿瘤药。60.5-取代的9-氧杂蒽并-4-乙酸的结构与体内结肠38活性之间的关系。

  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。

  Analogues of 9-oxo-9H-xanthene-4-acetic acid (XAA) bearing small, lipophilic 5-substituents are among the most dose-potent compounds yet reported with the capability of causing hemorrhagic necrosis of implanted colon 38 tumors in mice. To further extend structure-activity relationships among this class of compound, a series of XAA derivatives bearing two small lipophilic groups at various positions

  带有小的，亲脂性的5个取代基的9-氧代9H-氧杂蒽-4-乙酸（XAA）的类似物是迄今已报道的最强剂量化合物，具有引起小鼠植入的结肠38肿瘤出血性坏死的能力。为了进一步扩展这类化合物之间的构效关系，已经制备并评估了一系列在不同位置带有两个小的亲脂基团的XAA衍生物。特别是5，6-二取代的化合物始终显示出高水平的剂量效力和活性，这表明这是取代的9-氧代-9H-氧杂蒽-4-乙酸中的最佳构型。5,6-二甲基和5-甲基-6-甲氧基是最有效的类似物，

  A series of 16 analogues of the solid tumor active compound 9-oxo-9H-xanthene-4-acetic acid (XAA), with variations in the acetic acid side chain, have been prepared and evaluated for their ability to cause early haemorrhagic necrosis of colon 38 tumors in mice. The results extend the previous SAR for this class and confirm the necessity for a carboxylic acid group in a fixed disposition with respect to the xanthenone chromophore. None of the compounds showed superior potency to XAA itself, with virtually all alterations in the nature of the anionic center or its geometry with respect to the chromophore greatly reducing or abolishing activity. However, alpha-methylation of the side chain was permissible, and the two enantiomers of 5-methyl-alpha-methyl-XAA were separated and tested. Both were active, but the S-(+) enantiomer was much more dose-potent than the R-(-) enantiomer, in both the in vivo tumor necrosis assay and an in vitro assay measuring the stimulation of nitric oxide production by macrophages. This suggests that the enantiomers have different intrinsic activities, rather than differing in their vivo metabolism.
