Some new benzenesulfonamides, disubstituted sulfonylureas, and sulfonylthioureas substituted basically with 3-(2-thienyl or 3-pyridyl)-indeno[1,2-c]pyrazol(in)e counterpart were synthesized to be evaluated for their in vitro antitumor activity. Some of the thioureido derivatives were cyclized to the corresponding five-membered thiazolidinons, thiazolines, and the six-membered thiazinones as interesting
合成了一些新的苯磺酰胺,二取代的磺酰脲类和基本上被3-(2-噻吩基或3-吡啶基)-茚并[1,2-c]吡唑(in)e对应物取代的磺酰硫脲,以评估它们的体外抗肿瘤活性。一些硫脲基衍生物作为有趣的结构变体被环化为相应的五元噻唑烷酮,噻唑啉和六元噻嗪酮。根据美国国家癌症研究所(NCI)的针对疾病的体外人体细胞筛选小组试验的协议,有13种化合物显示出广阔的抗肿瘤活性。通常,含有噻吩基部分的化合物显示出比含有吡啶基部分的化合物更好的抗肿瘤光谱。化合物5,4-(3-(2-噻吩基)-3H-茚并[1,2-c]吡唑-2-基)-苯磺酰胺[GI 50,TGI和LC 50(MG-MID)值分别为13.2、33.1和69.2μM]被证明是本研究中最活跃的成员,对所有测试的亚组肿瘤细胞系的效力各不相同,并且对GI 50(分别为3.30和8.68μM)和TGI水平(分别为15.7和22.3μM)的白血病和前列腺亚组。
