characterization of some novel derivatives of 3‐methyl‐2‐(4‐substituted phenyl)‐4,5‐dihydronaphtho[1,2‐c]pyrazoles carrying different pharmacophores and heterocyclic rings that are relevant to potential antitumour and cytotoxic activities are described. The antitumour activities of the newly synthesized compounds were evaluated according to the protocol of the National Cancer Institute (NCI) in‐vitro
3-甲基-2-(4-取代苯基)-4,5-二氢萘并[1,2-c]吡唑的一些新型衍生物的合成策略和表征,它们带有与潜在的抗肿瘤和细胞毒性相关的不同药效团和杂环活动进行了描述。根据美国国家癌症研究所 (NCI) 体外疾病导向的人类细胞筛选面板试验的协议,评估了新合成化合物的抗肿瘤活性。结果显示为6种化合物,分别为6、8、11、15、17和18;在 60 细胞系测定中显示出有希望的体外抗肿瘤活性。磺酰硫脲基成为最有利的药效团。将这种硫脲基对应物纳入 6 元 1,3 - thiazinan - 5-one 比 5-元噻唑和 6-元 1,3-thiazinan - 4-one 环系统显示出更好的抗肿瘤活性。进一步的环扩张导致抗肿瘤活性完全丧失。类似物 18, 3-benzyl-2- [4- (3-methyl-4,5-dihydronaphtho- [1,2-c] pyrazol-2-yl) -benzosulfonylimino]
