virtual absence of cytotoxic properties in series 3 and 4. Most of the compounds were administered intraperitoneally to mice using doses up to and including 300 mg/kg. No mortalities were noted. The inhibiting effect of most of the compounds towards Helicobacter pylori is noteworthy. The modes of action of representative compounds include the induction of apoptosis while some compounds weakly inhibited
将5-芳基-1-(4-硝基苯基)-3-氧代-1,4-戊二烯基药效团掺入四个系列的化合物1-4中。化合物1a-g包含3-亚芳基-1-(4-硝基苯基亚甲基)-2-氧代-3,4-二氢-1H-萘的簇,而类似物2a-g由一组6-芳基-2- (4-硝基苯基亚甲基)环己酮。在这项研究中制备的其他三种化合物是1-(4-硝基苯基亚甲基)-3-(3,4,5-三甲氧基苯基亚甲基)-2-氧代-2,3-二氢-1H-茚3a以及两个5-亚芳基- 2-(4-硝基苯基亚甲基)环戊酮4a,b。针对人的Molt 4 / C8和CEM T淋巴细胞以及鼠L1210细胞对化合物进行了评估。一般来说,系列1的化合物显示出明显的细胞毒性,IC50值在1-5 microM范围内,而系列2的相关环己基类似物的效力稍低(IC50值主要为5-10 microM)。在所有四个系列中都存在的两个芳基环的相对位置被认为对生物活性有显着贡献,并且可能解
