Abstract:
The present invention relates to heterodimeric conjugates of neomycin-chloramphenicol, of formula 1, their preparation and their use. Because of their heterodmieric structure, they can recognize both stem and loop of RNA motif and show binding ability to a certain RNA such that they have an enhanced pharmaceutical efficacy and reduced side effect which can be caused by non-specific drugs. For these reasons, they can be effectively used as an antiviral agent, an antibacterial agent or an anticancer drugs.
Abstract:
PURPOSE: Provided is a heterodimer of neomycin and chloramphenicol with improved specificity to a target RNA molecule to increase the medicinal efficacy while decreasing adverse effects due to the non-specific drugs. It is effectively used as an anti-virus agent, an anti-bacteria agent, or an anti-cancer agent. CONSTITUTION: A heterodimer(formula 1) of neomycin and chloramphenicol is structured such that the heterodimer is specific-coupled to 16S rRNA, RRE RNA, or TS RNA. In the formula(1), n is an integer of 2-10 and, more particularly, 3, 6 or 9. The specific coupling of the heterodimer to the RNA is characterized by simultaneously recognizing the stem and the loop of the RNA. The specific coupling is intrinsic to the sequence of RNA.
