Title:
ANTIBACTERIAL SUBSTANCES INJURING BACTERIAL CELL MEMBARANE AND METHODS OF USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2006/075580
Kind Code:
A1
Abstract:
A monomer injuring bacterial cell membrane which is a compound having a carbon cycle structure or a carbon/oxygen heterocycle structure, carrying two or more amino-type functional groups attached to one side of the cycle plane and showing an affinity for phospholipids in the other side of the cycle plane and exhibits a bacteriostatic effect of injuring bacterial cell wall, i.e., injuring bacterial cell wall while allowing the bacterium to sustain its proliferating ability; an oligomer injuring bacterial cell membrane which consists of two or more units of the above monomer bonded to each other; an antimicrobial monomer injuring bacterial cell membrane showing an activity of injuring bacterial cell membrane and an antimicrobial activity which belongs to the monomer injuring bacterial cell membrane as described above and in which an amino-type functional group has an aromatic ring; an antimicrobial oligomer injuring bacterial cell membrane which consists of two or more units of the above monomer bonded to each other; and various antimicrobial methods using these substances. Thus, it becomes possible to provide substances injuring bacterial cell membrane and antimicrobial substances injuring bacterial cell membrane which can be easily produced and methods of effectively utilizing the same.
