tyrosine nitration and antioxidant activity. The tested compounds are highly effective at very low concentration as anti-HCV, SSPE antioxidant and anticancer in the following ascending order 2d, 4c, 6b, 3b, 6c, 4d, 2b, 2c, 2a, 6a, 5b, 5a, 3a, 4b and 5c. It is worth to mention that all tested compounds are more potent than the reference standards used for comparing activity. All the measurements revealed
通过两步方法合成了三系列新颖的吡唑衍生物2b – d,4a – d和6a – d,分别使用酰氯1a – d和烯胺酮3a – d和5a – d作为起始原料。在分析和光谱数据的基础上,已经建立了所有新合成产物的结构。此外,某些产品2 – 6对HCV和亚急性硬化性全脑炎(SSPE)进行了测试。此外,还测试了化合物2 – 6对过氧亚硝酸盐诱导的酪氨酸硝化和抗氧化活性的抑制作用。所测试的化合物以极低的浓度作为抗HCV,SSPE抗氧化剂和抗癌剂,其有效浓度依次为2d,4c,6b,3b,6c,4d,2b,2c,2a,6a,5b,5a,3a,4b和5c。值得一提的是,所有测试的化合物均比用于比较活性的参考标准品更有效。所有测量结果表明,所有测试化合物的抗癌活性的作用机理是拓扑异构酶I抑制剂。
