A new series of compounds was prepared from 6-methoxyquinolin-8-amine or its N-(2-aminoethyl) analogue via Ugi-azide reaction. Their linkers between the quinoline and the tert-butyltetrazole moieties differ in chain length, basicity and substitution. Compounds were tested for their antiplasmodial activity against Plasmodium falciparum NF54 as well as their cytotoxicity against L-6-cells. The activity and the cytotoxicity were strongly influenced by the linker and its substitution. The most active compounds showed good activity and promising selectivity.
一系列新化合物是通过6-甲氧基喹啉-8-胺或其N-(2-氨基乙基)类似物经过Ugi-叠氮反应制备的。它们的连接剂在喹啉和叔丁基四唑基团之间的链长、碱性和取代基不同。这些化合物被测试其抗疟活性对抗疟原虫Plasmodium falciparum NF54以及其对L-6细胞的细胞毒性。活性和细胞毒性受连接剂及其取代基的影响很大。最活性的化合物表现出良好的活性和有前景的选择性。
