NaN3/H2SO4 reaction conditions. Twelve of the obtained compounds were in vitro screened by the US National Cancer Institute (NCI) for their ability to inhibit 60 different human tumor cell lines, where compound 24a presented a remarkable activity against 58 of the 60 cancer cell lines, with the most important GI50 values ranging from 0.047 to 8.16 μM and LC50 values ranging from 9.4 to > 100 μM. Additionally
通过施密特重排反应,由相应的1,2,3,4-tetrahydro-4合成了新颖的四氢-5 H-苯并[ e ] [1,4]二氮杂5-5-酮,其中几个含有喹啉药效团。NaN 3 / H 2 SO 4反应条件介导的喹诺酮类药物。美国国家癌症研究所(NCI)在体外筛选了十二种获得的化合物抑制60种不同人类肿瘤细胞系的能力,其中化合物24a对60种癌细胞系中的58种表现出显着的活性,其中最重要的是GI 50值范围从0.047至8.16μM和LC 50值范围从9.4到> 100μM。此外,其中一些被评估为抗疟药,抗锥虫病药和抗疟药。化合物22g 对恶性疟原虫的最佳抗疟疾反应为EC 50 = 13.61μg/ mL ,而化合物24d对克氏锥虫则表现出高活性。和Leishmania(V)panamensis的EC 50分别 为2.78μg/ mL和3.35μg/ mL。
