The present invention relates to a broken or kinked helical peptide or peptide analogue and the use thereof, and more particularly to a Gram-negative bacterial membrane-penetrating peptide or peptide analogue wherein an alpha-helical amphipathic peptide composed of hydrophobic amino acids and hydrophilic amino acids has a kinked structure, or an antimicrobial composition employing the specific activity of the peptide against the Gram-negative bacterial membrane, or an antimicrobial composition for co-administration, or a conjugate comprising a drug linked to the peptide or peptide analogue, or an antibiotic comprising the same.

Broken or folded helical peptide or peptide analog exhibiting antimicrobial activity against gram-negative bacteria, and use thereof

The present invention relates to a stapled peptide, a preparation method thereof and the use thereof, and more specifically to an amphipathic alpha-helical stapled peptide comprising hydrophobic amino acids and hydrophilic amino acids, a preparation method thereof, and the use thereof for intracellular delivery of an active substance.

Cell penetrating stapled peptide, manufacturing method therefor, and use thereof

The present invention relates to a screening method of an amphiphilic peptide specifically binding to hairpin RNA, more precisely a screening method of an amphiphilic peptide having specificity and strong binding strength to target hairpin RNA using peptide library comprising those peptides having modifications of both hydrophilic face and hydrophobic face. The method of the present invention provides a screening method of an amphiphilic peptide which is specific to hairpin RNA. So, the peptide selected by the method of the present invention can be effectively used for the study of hairpin RNA functions and for the production of a novel drug using an artificial peptide binding to a hairpin RNA target.

Process for screening of a binding amphiphilic peptides specific for hairpin RNA

The present invention relates to a screening method for RNA specific binding peptide using alpha-helical peptides. The screening method for RNA specific binding peptide of the present invention using alpha-helical peptides enables the selection of a peptide having strong binding capacity to a specific RNA having particular morphology and nucleotide sequence and the investigation of functions of RNA using the selected peptides, and is very useful for the production of a new drug using synthetic peptide having more powerful and specific binding capacity to RNA than those of natural peptides.

Process for screening of a binding peptide specific for specific RNA and RNA binding peptides therefrom

The present invention relates to cinnamic acid dimers, their preparation and the use thereof for treating neurodegenerative disease, which have excellent effect on enhancing the learning and memory-retention ability in vivo and have fewer side-effects by showing no hormone properties, even when administered for a long period of time, and thus which can be used for neurodegenerative disease including dementia.

Cinnamic acid dimers, their preparation and the use thereof for treating neurodegenerative disease

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.

Carbohydrate-specific peptides which have a strong affinity and preparations method thereof

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.
