Chronic hepatitis B viral infection is a significant health problem world-wide, and currently available antiviral agents suppress HBV infections, but rarely cure this disease. It is presumed that antiviral agents that target the viral nuclear reservoir of transcriptionally active cccDNA may eliminate HBV infection. Through a series of chemical optimization, we identified a new series of glyoxamide derivatives affecting HBV nucleocapsid formation and cccDNA maintenance at low nanomolar levels. Among all the compounds synthesized, GLP-26 displays a major effect on HBV DNA, HBeAg secretion and cccDNA amplification. In addition, GLP-26 shows a promising pre-clinical profile and long-term effect on viral loads in a humanized mouse model.

慢性乙型肝炎病毒感染是世界范围内的一个重大健康问题，目前可用的抗病毒药物可以抑制 HBV 感染，但很少能治愈这种疾病。据推测，靶向转录活性 cccDNA 病毒核库的抗病毒药物可能会消除 HBV 感染。通过一系列化学优化，我们确定了一系列新的乙二酰胺衍生物，它们在低纳摩尔水平下影响 HBV 核衣壳形成和 cccDNA 维持。在合成的所有化合物中，GLP-26 显示出对 HBV DNA、HBeAg 分泌和 cccDNA 扩增的主要影响。此外，GLP-26 在人源化小鼠模型中显示出良好的临床前特征和对病毒载量的长期影响。
