発明の名称 (英語) SUGAR DERIVATIVE OR SALT THEREOF, AND ANTIBACTERIAL AGENT OR ANTIBACTERIAL ACTIVITY ENHANCER USING SAME
発明の概要(英語) [Problem] To provide a compound having excellent antibacterial properties and a compound having an excellent ability to enhance antibacterial properties of another antibacterial agent.
[Solution] A sugar derivative having an antibacterial function which is represented by chemical formula (1) or (2), wherein monosaccharides are bonded via glycoside bonds in a chain or cyclic manner, or a salt thereof. In the formulae, R1 represents an amino group-containing structure and n represents an integer of 3 or greater. A sugar derivative having an antibacterial activity-enhancing function which is represented by chemical formula (5) or (6), wherein monosaccharides are bonded via glycoside bonds in a chain or cyclic manner, or a salt thereof. In the formulae, R3 represents an amino group-containing structure, R4 represents an acetyl group or a propanoyl group, and n represents an integer of 3 or greater.
従来技術、競合技術の概要(英語) BACKGROUND ART
Since the discovery of penicillin, synthetic antibiotics or antimicrobial agent a variety of systems have been developed, for the treatment of infectious diseases has been used. However, methicillin resistant Staphylococcus aureus (MRSA) are resistant to antimicrobial agents is represented by an existing multi-agent has a serious increased up to the resistant bacteria, development of new anti-microbial agent has been craving.
General drug resistance is less likely to occur as the antimicrobial agent, polymyxin B of the film-operated mechanism such as anti-microbial material that is present. However, due to their complex structure and a natural, artificial manufacturing, and further improve the excellent activity as it is not easy. For this reason, an artificial anti-microbial material may be combined and performed, a specific chemical structure and having a chemically modified cyclodextrin has been used as an antibacterial agent (for example see Patent Document 1, 2, 3).
