Abstract:
The present invention relates to a novel method for producing a selenyl-substituted aromatic aldehyde compound, specifically a novel method for producing a selenyl-substituted aromatic aldehyde compound including a step of forming a selenolate nucleophile and nucleophilic-substituting an aromatic aldehyde starting material.
Abstract:
본 발명은 특정 화합물 또는 그의 염을 유효성분으로 함유하는 항균용 조성물에 관한 것으로, 상기 화합물 또는 그의 염은 항균용 약제 또는 건강식품 외에도 인공삽입물, 예를들어 중심정맥관, 인공관절, 인공판막 등에 코팅함으로써 인공삽입물의 바이오필름 형성을 억제함과 동시에 세균을 직접적으로 억제하는 항균활성을 나타낼 수 있어 인공삽입물 감염 방지를 위한 코팅 조성물로서 매우 유용하게 사용될 수 있다.
Abstract:
PURPOSE: A manufacturing method of a selenophene-fused aromatic compound is provided to obtain various selenophene-fused aromatic compounds at a high yield by varying the kinds of aromatic stating materials. CONSTITUTION: A manufacturing method of a selenophene-fused aromatic compound represented by chemical formula 2 comprises: a step of preparing a diselenide compound represented by chemical formula R^1-CH2-Se-Se-CH2-R^1, a solvent, and a reducing agent; and a step of conducting a reaction by adding an aromatic starting material represented by chemical formula 1 and a base into the reaction mixture. The solvent is selected among dimethylsulfoxide, tetrahydrofuran, CH2Cl2, CH3CN, CH3NO2, CHCl3, ClCH2, CH2Cl, alcohol, an aromatic solvent, and a combination thereof.
Abstract:
PURPOSE: A quorum sensing inhibitor and an antibacterial composition using the same are provided to suppress quorum sensing between bacteria, and to prevent or treat infection or diseases. CONSTITUTION: An antibacterial composition using a quorum sensing inhibitor against a pathogenic microorganism contains 1-(5-bromothiophene-2-sulfonyl)-1H pyrazole of chemical formula 1 as an active ingredient. The antibacterial composition is a pharmaceutical composition, a feed composition, a food composition, and a food additive composition.
Abstract:
PURPOSE: An antiviral or anticancer drug containing peptide analogue with histidine is provided to control NF-kappaB activity and to prevent or treat NF-kappaB-associated diseases. CONSTITUTION: A peptide analogue with histidine is denoted by formula I(X1-His-X2-X3-His-Gly-X4). In formula I, X does not exist or is at least one amino acid or amino acid having alkyl or an aryl group; X2 is an amino acid having beta-amino acid, gamma-amino acid, D-form amino acid, or N-methyl amino acid; X3 does not exist or is an amino acid with gamma-amino acid, D-form amino acid or N-methyl amino acid; X3 does not exist or is an amino acid having L-form amino acid, D-form amino acid, or N-methyl amino acid; and X4 is an amino acid having L-form amino acid, D-form amino acid or N-methyl amino acid. The peptide analogue is Gly-His-β-Ala-Gln-His-Gly-Val. A composition for treating a NF-kappaB-associated disease contains NF-kappaB activity-regulating material having the peptide analogue and hydrate or salt thereof as an active ingredient.
