method. Using SYBR Green I assay, these hybrid molecules were examined for anti-plasmodial activity against Chloroquine-sensitive 3D7 and Chloroquine-resistant K1 strains of Plasmodium falciparum. The compounds 9o IC50s (µM) 1.983D7, 1.98K1} and 9p IC50s (µM) 1.923D7, 5.45K1} were found to be the most potent anti-plasmodial compounds in the series. Also, all these compounds were found to be non-cytotoxic
咪唑并[1,2- a ]吡啶衍生物和6-溴黄酮之间的有效交叉偶联反应已得到很好的建立。该反应通过钯催化的交叉偶联反应进行,以良好至优异的收率提供咪唑并[1,2- a ]吡啶-黄酮杂化物。该方法的主要优点是反应时间短、产率高、底物范围广。使用 SYBR Green I 测定,检查了这些杂合分子对氯喹敏感的 3D7 和氯喹耐药的恶性疟原虫K1 菌株的抗疟原虫活性。化合物9o IC 50 s (μM) 1.98 3D7 , 1.98 K1 } 和9p IC50 s (μM) 1.92 3D7 , 5.45 K1 }被发现是该系列中最有效的抗疟原虫化合物。此外,所有这些化合物均被发现对 Vero 细胞无细胞毒性,其 CC 50 s > 100 µM。我们对化合物9o和9p进行了显微镜检查实验,结果对疟疾寄生虫的生长产生了巨大影响。还在野生型Pf -DHFR-TS(恶性疟原虫)的结合位点中检查了
