both immobilized on TOYOPEARL AF‐Amino‐650M beads and used for mass spectrometry‐based target identification experiments using total lysates of HCMV‐infected primary human fibroblasts. Two major groups of novel target candidates, namely cytoskeletal and mitochondrial proteins were obtained. Two putatively compound‐binding viral proteins, namely major capsid protein (MCP) and envelope glycoprotein pUL132
生物活性化合物的二聚体、三聚体和树枝状聚合物的生成是最近为发现新的有效候选药物而开发的一种方法。在此,我们展示了新的青蒿素衍生二聚体和树枝状聚合物的合成,并研究了它们对疟原虫恶性疟原虫3D7 株和人巨细胞病毒 (HCMV) 的作用。二聚体7是最活跃的化合物(EC 50 1.4Ñ米)在抗疟疾功效方面,是更有效的比标准药物双氢青蒿素(EC 50 2.4Ñ米),artesunic酸(EC 50 8.9Ñ米)和氯喹(EC 50为9.8N米)。Trimer 4作为体外抗 HCMV 复制中最具活性的药物脱颖而出,其 EC 50值为 0.026 μm,比两种参考药物更昔洛韦 (EC 50 2.60 μm ) 和青蒿琥酯 (EC 50 5.41 ) 的活性更高μ米)。此外,青蒿素衍生的二聚体13和三聚体15首次固定在 TOYOPEARL AF-Amino-650M 珠上,并用于使用 HCMV 感染的原代人
