摘要:
The present invention relates to heterodimeric conjugates of neomycin-chloramphenicol of formula 1, their preparation and their use. Because of their heterodimeric 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, the can be effectively used as an antiviral agent, an antibacterial agent or an anti cancer drugs.

The present invention relates to novel oxazolidinone derivatives represented as following compound I and a process for the preparation thereof. The compounds of the present invention have wide antibacterial spectrums superior antibacterial activity and low toxicity. Therefore, it can be expected to use as novel antibacterial agent. wherein, R1 is alkylcarboxyl group or —CH2R2 (wherein, R2 is OH, argido group, —OR3 (wherein, R3 is C1-4 alkyl, methansulfonyl, p-toluensulfonyl, carboxyl, C1-4 alkylcarboxyl, C1-4 alkylcarbonyl, benzyloxycarbonyl, or imidazolylcarbonyl), or —NHR4).
摘要:
The present invention relates to carbohydrate-specific peptides, which have a strong affinity and preparation method thereof. Particularly, the present invention relates to carbohydrate-specific peptides, which have been developed to have an increased strong affinity to carbohydrates by the multiple combinations of peptides having carbohydrates-specific amino acid sequences and preparation method thereof. Carbohydrate-specific peptides of the present invention have a very strong affinity under micromol, so that they can shut off recognition between cells transferred by specific carbohydrates, which means they can be used for the treatment of diseases mediated by recognition between cells and used as a diagnostic kit which diagnoses diseases by confirming the existence of any specific carbohydrate.
