promising broad spectrum antitumor activity against most of the tested subpanel tumor cell lines (GI50 < 100 microM). Compound 3, 4-(3-(4-chlorophenyl)-4H-indeno[1,2-c]pyrazol- 2-yl)-benzenesulfonamide; although it did not show the highest growth inhibitory value (GI50 (MG-MID) 13.2 microM), it proved to be the most active analog in this study with the highest cytostatic and cytotoxic potentials (TGI and
描述了一系列被苯磺酰胺,N1,N3-二取代的磺酰脲,磺酰硫脲药效团以及一些衍生的噻唑烷酮和噻唑啉环系统取代的3-(4-氯苯基)-[1,2-c]吡唑(in)es的合成。所有新合成的目标化合物均经过NCI体外疾病导向的抗肿瘤筛选,以评估其抗肿瘤活性。八个化合物即;2-4、7、8、10、13和16;对大多数测试的亚组肿瘤细胞系(GI50 <100 microM)显示出有希望的广谱抗肿瘤活性。化合物3,4-(3-(4-氯苯基)-4H-茚并[1,2-c]吡唑-2-基)-苯磺酰胺;尽管它没有显示出最高的生长抑制值(GI50(MG-MID)13.2 microM),它被证明是这项研究中活性最高的类似物,具有最高的细胞抑制和细胞毒性潜能(TGI和LC50(MG-MID)浓度分别为33.1和66.1 microM)。通常,氧化的吡唑显示出比其母体吡唑啉类似物更好的抗肿瘤活性,而苯磺酰胺和N1,N3-二取代的
