A series of pyrazole derivatives with two and three alkylating sites were prepared and their cytotoxicity against cancer cells as well as antitumor activity against L1210 was investigated. The best result of cytotoxicity was obtained with the trichloride 5 and the best antitumor activity (ILS 33%) with the dibromide 3. These results can provide valuable information for further study of the more effective antitumor agent. Keywords: pyrazole, synthesis, cytotoxicity, antitumor activity, polyalkylator.
一系列具有两个和三个烷基化位点的吡唑衍生物已经制备,并对它们在癌细胞中的细胞毒性以及对L1210的抗肿瘤活性进行了研究。最佳的细胞毒性结果是三氯化物5,最佳的抗肿瘤活性(ILS 33%)是二溴化物3。这些结果可以为进一步研究更有效的抗肿瘤药物提供宝贵信息。关键词:吡唑,合成,细胞毒性,抗肿瘤活性,多烷基化合物。
