Title
(EN) A THERAPEUTIC INHIBITOR FOR EBV-ASSOCIATED TUMOR WITH TAILOR RESPONSIVE OPTICAL IMAGING
(FR) INHIBITEUR THÉRAPEUTIQUE POUR UNE TUMEUR ASSOCIÉE AU EBV AVEC UNE IMAGERIE OPTIQUE SENSIBLE PERSONNALISÉE
Abstract
(EN)
It is provided a nucleus-permeable small-molecule inhibitor, L2P4 (where L2 is 4-(4-( Diethylamino)styryl)-N-carboxymethylpryidinium 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 method of treating and imaging EBV-associated cancers is also provided.
(FR)
L'invention concerne un inhibiteur à petite molécule à perméabilité nucléaire, L2P 4 (où L2 représente le chlorure de 4-(4-(diéthylamino)styryl)-N-carboxyméthylpryridinium et P4 représente une séquence d'acides aminés comprenant CAhxYFMVFGGRrRK et ils ont été couplés par l'intermédiaire d'une liaison amide) et la synthèse de ce dernier, qui cible efficacement l'interface de dimérisation de EBNA1, un processus critique pour la croissance des EBV et des tumeurs associées. L'invention concerne également le procédé de traitement et d'imagerie de cancers associés au EBV.
