The present invention relates to cinnamyl-rhodanine derivative compounds or pharmaceutically acceptable salts thereof, and to a pharmaceutical composition comprising the compounds as active ingredients. More particularly, cinnamyl-rhodanine derivative compounds of the present invention inhibit the migration of cancer cells through an inhibition of activity of protein phosphatase (PPase) of PRL-3(phosphatase of regenerating liver), and therefore, can be valuably used in preventing or treating metastasis of cancer. Further, cinnamyl-rhodanine derivative compounds of the present invention inhibit the migration of vascular endothelial cells and thus inhibit angiogenesis by the same mechanism, and therefore, can be valuably used in preventing or treating angiogenesis-related diseases caused by anticancer drug or abnormal angiogenesis.

The present invention relates to nanoparticles including 24 antibody-binding peptide-ferritin fusion protein monomers, the nanoparticles being characterized in that six partial structures having a 4-fold symmetry point are formed due to ferritin, and an antibody-binding peptide is fused to the ferritin in a range of ±10 a.a. of the 4-fold symmetry point such that 4 antibody-binding peptides are positioned in the vicinity of the 4-fold symmetry point; and also relates to uses of the nanoparticles. The present invention can be used for biochips, drug delivery systems, disorder diagnosis, and the development of treating agents by producing the fusion protein through the introduction of the sequence of the antibody-binding peptide into the ferritin, and using the fusion protein to allow the antibody to strongly bind to the ferritin without any damage to the antibody structure.

The present invention relates to a probe for iFRET and to a usage of same. More particularly, the present invention relates to the probe for iFRET, a method for manufacturing the probe for iFRET, a method for searching a target protein-specific binding site or a molecule having the binding site using the probe for iFRET, and a method for imaging the target protein through the probe for iFRET. The probe for iFRET, according to the present invention, unlike the existing FRET method, uses an amino acid inside a protein as a fluorescence donor, thereby using only one fluorescent substance, and has an light emitting wavelength which is separated from a protein intrinsic fluorescence, thereby having high specificity and sensitivity and thus allowing easier and more accurate analysis of the amount, activity, and mechanism, among others, of a variety of proteins.

The present invention relates to a composition for preventing and treating inflammatory disease containing an Ardisia tinctoria (Ardisia tinctoria Pit.) extract or a fraction thereof as an active ingredient. More specifically, it has been confirmed that an Ardisia tinctoria extract or a fraction thereof suppresses the production of nitric oxide which is sharply increased by inflammation induction, and it has been confirmed that the Ardisia tinctoria extract is effective in markedly reducing the amount of PGE2, IL-6 (interleukin-6) and IL-1 beta cytokine in a dose dependent fashion, and that it inhibits the expression of iNOS and the COX2 gene and protein and inhibits nuclear translocation of p65 protein and phosphorylation of signal transducers. Also, it has been confirmed that the Ardisia tinctoria extract and an ethyl acetate fraction are effective in suppressing inflammation in a carrageenan-induced mouse podedema model as well. Consequently, the Ardisia tinctoria extract or fraction can be used to advantage as an active ingredient in compositions for preventing and treating or alleviating inflammatory related diseases, or compositions for topical skin preparations, cosmetic compositions and health foods.

The present invention relates to dip pen nanolithography technique which is an imaging method using a atomic force microscope, and more specifically, to a preparation apparatus and a preparation method for a nanopositioning substrate of an ink system using dip pen nanolithography with a single or multiple tips. According to the present invention, with respect to the imaging method using the atomic force microscope, provided is the preparation apparatus and the preparation method for the nanopositioning substrate of the ink system using dip pen nanolithography with single or multiple tips, comprising: a first ink storage portion and a second ink storage portion for coating a tip with an ink; a first washing portion and a second washing portion for washing the tip coated with an ink; a pattern carving portion for carving a tip on a substrate; an electrode connection portion for applying voltage; and a position checking portion for checking or determining the position of the coated tip on a micrometer-scale area, wherein the position checking portion is formed to check position through the change of a voltage-current, the extent of bending of an AFM tip with respect to voltage and an AFM image; and it is possible to increase the density of a biomaterial on the micrometer-scale area by integrating a large number of the biomaterial on the substrate by using the reproducibility of the atomic force microscope tip position.
摘要:
Two vIRF4 (Kaposi's-sarcoma-associated-herpesvirus vIRF4) peptides, vif1, corresponding to aa202-216 of vIRF4, and vif2, corresponding to aa220-236 of vIRF4, are potent and selective HAUSP antagonists. The vif1 and vif2 peptides robustly suppress HAUSP DUB enzymatic activity, ultimately leading to p53 -mediated anti-cancer activity. The vif1 and vif2 peptides, along with their homologues, are useful in treating cancer through regulation of p53 activity in a cancer cell. Also disclosed is the crystalline structure of vIRF4-HAUSP TRAF domain complex. The structure is useful in computer aided drug design for identifying an agent that interacts with and inhibits HAUSP, resulting in p53 medicated cell cycle arrest of cancer cells.

The present invention relates to a microsatellite marker for Chlorella, and more particularly, to a novel microsatellite molecular marker capable of interspecific and intraspecific classification of micro-algae Chlorella strains and to a primer for amplifying same. The Chlorella-derived novel microsatellite molecular marker of the present invention may enable analysis of the polymorphism genotype of an allele on the basis of the number of repetitions of a short base sequence existing in Chlorella genes, thus not only enabling interspecific classification of several Chlorella species having close phylogenetic relationships but also enabling clear intraspecific classification of Chlorella strains within an identical species. Therefore, the marker of the present invention can be used as an interspecific classification marker for Chlorella or a marker for distinguishing intraspecific strains.

The present invention relates to a method for preparing a diol compound from glycerol using a variant strain, and more specifically to a method for producing 1,3-propanediol and 2,3-butanediol at a high yield by using a variant of a microorganism capable of fermenting glycerol that lacks a gene for coding lactate dehydrogenase. According to the present invention, the production amount of 1,3-propanediol and 2,3-butanediol can be significantly improved through a novel culturing method of a glycerol fermentation microorganism variant.
