発明の名称 (英語) | NARROW-SPECTRUM ANTIBACTERIAL ANTIBIOTICS TARGETING SPECIFIC TYPES OF BACTERIA THAT SYNTHESIZES MENAQUINONE THROUGH AN ALTERNATIVE PATHWAY VIA FUTALOSINE OR 6-AMINODEOXYFUTALOSINE AS AN INTERMEDIATE. |
発明の概要(英語) | Alternative menaquinone biosynthetic pathway via futalosine or 6-aminodeoxyfutalosine as an intermediate (futalosine pathway) is an attractive target for new narrow-spectrum antimicrobial agents. Siamycin I and fatty acids were provided as selective antimicrobial activity against bacteria such as Helicobacter and Campylobacter, which depend on the futalosine pathway to grow. Specifically, siamycin I and omega-3 polyunsaturated fatty acids inhibited the colonization of H. pylori in vivo and thus siamycin I and omega-3 polyunsaturated fatty acids could be a new narrow-spectrum antibiotic for Helicobacter and Campylobacter |
特許請求の範囲(英語) |
[claim1] 1. Siamycin I or a fatty acid for the treatment or prevention of bacterial infections or the diseases caused by bacterial infections in a subject, wherein the bacterium synthesize menaquinone through the futalosine pathway, and wherein the siamycin I or a fatty acid inhibits the futalosine pathway in the treatment or prevention of bacterial infections or the diseases caused by bacterial infections in a subject. [claim2] 2. Siamycin I or a fatty acid for inhibiting synthesis of menaquinone through the futalosine pathway by a bacterium in a subject who is infected by the bacterium comprising administration of siamycin I or a fatty acid to the subject, wherein the bacterium synthesize menaquinone through the futalosine pathway, and wherein the siamycin I or a fatty acid inhibits the futalosine pathway. [claim3] 3. The Siamycin I or a fatty acid of claim 1 or 2, wherein the bacterium is selected from a group consisting of genus of Helicobacter, Campylobacter, Wolinella and Streptomyces. [claim4] 4. The Siamycin I or a fatty acid of claim 1 or 2, wherein the bacterium is a Helicobacter pylori, [claim5] 5. The Siamycin I or a fatty acid of claim 1 or 2, wherein the fatty acid is at least one fatty acid that is selected from a group consisting of omega-3 fatty acids, α-linolenic acid, EPA, DHA, oleic acid, linoleic acid, and arachidonic acid. [claim6] 6. A method for the treatment or prevention of bacterial infections or the diseases caused by bacterial infections in a subject comprising administration of siamycin I or a fatty acid to the subject, wherein the bacterium synthesize menaquinone through the futalosine pathway, and wherein the siamycin I or a fatty acid inhibits the futalosine pathway. [claim7] 7. A method for inhibiting synthesis of menaquinone through the futalosine pathway by a bacterium in a subject who is infected by the bacterium, comprising administration of siamycin I or a fatty acid to the subject, wherein the bacterium synthesize menaquinone through the futalosine pathway, and wherein the siamycin I or a fatty acid inhibits the futalosine pathway. [claim8] 8. A pharmaceutical composition comprising siamycin I or a fatty acid for use in treatment or prevention of bacterial infections or the diseases caused by bacterial infections in a subject, wherein the bacterium synthesize menaquinone through the futalosine pathway, and wherein the siamycin I or a fatty acid inhibits the futalosine pathway in the treatment or prevention of bacterial infections or the diseases caused by bacterial infections in a subject. [claim9] 9. A pharmaceutical composition comprising siamycin I or a fatty acid for use in inhibiting synthesis of menaquinone through the futalosine pathway by bacterium in a subject who is infected by the bacterium comprising administration of siamycin I or a fatty acid to the subject, wherein the bacterium synthesize menaquinone through the futalosine pathway, and wherein the siamycin I or a fatty acid can inhibit the futalosine pathway. [claim10] 10. A method for the prevention of bacterium propagation in food, feedstuff or drinking water that contain siamycin I or a fatty acid. [claim11] 11. The method of claim 10, wherein feedstuff or drinking water application in combating Campylobacter propagation in poultry. |
