This invention provides a nucleus-permeable small-molecule inhibitor, L2P4 (where L2 is 4-(4-(Diethylamino)styryl)-N-carboxymethylpyridinium chloride and P4 is an amino acid sequence comprising CAhxYFMVFGGRrRK and they were coupled through amide bond) and synthesis thereof, which effectively targets the dimerization interface of EBNA1, a critical process for the growth of EBVs and the associated tumors. The present invention also provides method of treating and imaging EBV-associated cancers.
本发明提供了一种可渗透细胞核的小分子
抑制剂L2P4(其中
L2为4-(4-(
二乙基氨基)
苯乙烯基)-N-羧
甲基吡啶氯化物,P4为由CAhxY
FMVFGGRrRK组成的
氨基酸序列,二者通过酰胺键偶联)及其合成方法,该
抑制剂可有效靶向EBNA1的二聚化界面,而二聚化界面是EBV及相关肿瘤生长的关键过程。本发明还提供了治疗和成像 EBV 相关癌症的方法。
