Une fois que la r\u00e9sistance bact\u00e9rienne est d\u00e9velopp\u00e9e, elle peut non seulement \u00eatre transmise \u00e0 la descendance par les g\u00e8nes, mais aussi \u00e0 d'autres bact\u00e9ries par la liaison bact\u00e9rienne. Les experts craignent que la r\u00e9sistance aux m\u00e9dicaments ne devienne une catastrophe mondiale sans aucun signe de soulagement. Le d\u00e9veloppement de nouveaux types de m\u00e9dicaments antibact\u00e9riens est une t\u00e2che urgente \u00e0 laquelle le monde est confront\u00e9, et la recherche de composants antibact\u00e9riens dans les m\u00e9dicaments \u00e0 base de plantes est une orientation importante dans le d\u00e9veloppement de m\u00e9dicaments antibact\u00e9riens. Le gingembre est l'une des principales sources d'ingr\u00e9dients antibact\u00e9riens. Au cours de la derni\u00e8re d\u00e9cennie, de nombreux compos\u00e9s chimiques dot\u00e9s d'une excellente activit\u00e9 antibact\u00e9rienne ont \u00e9t\u00e9 d\u00e9couverts dans les plantes de gingembre.<\/p>\n<p>Le gingembre (Zingiber officinale Roscoe) est une plante traditionnelle de m\u00eame origine alimentaire et m\u00e9dicinale, appartenant \u00e0 la famille du gingembre et au genre gingembre. Le gingembre a des effets pharmacologiques tels qu'anti-inflammatoires, antibact\u00e9riens, antitumoraux, antioxydants, favorisant la digestion, am\u00e9liorant la circulation sanguine, renfor\u00e7ant l'estomac et soulageant la douleur. Les ging\u00e9rols sont les composants \u00e9pic\u00e9s et les principaux ingr\u00e9dients actifs du gingembre. Les compos\u00e9s du ging\u00e9rol ont attir\u00e9 l'attention en raison de leurs activit\u00e9s biologiques telles que les propri\u00e9t\u00e9s antitumorales et antibact\u00e9riennes. [Le ging\u00e9rol et le ging\u00e9rol [6] ont une bonne activit\u00e9 antibact\u00e9rienne \u00e0 large spectre contre les souches de MRSA SA1199B (NorA), XU212 (TetK) et RN4220 (MSRA), et ont de forts effets inhibiteurs sur le transfert de liaison du plasmide R. Lee et al. Lee et al. ont constat\u00e9 que [6] - ging\u00e9rol, [8] - ging\u00e9rol et [6] - ging\u00e9rol peuvent inhiber la formation de biofilms chez Candida albicans, mais [10] - ging\u00e9rol, [8] - ging\u00e9rol et [10] - ging\u00e9rol, qui ont des structures similaires, n'ont pas montr\u00e9 d'activit\u00e9 inhibitrice \u00e0 une concentration de 100 \u03bc g\/mL. Bien que certains chercheurs pensent que le raccourcissement de la longueur de la cha\u00eene des composants similaires au ging\u00e9rol peut entra\u00eener une diminution de l'activit\u00e9 antibact\u00e9rienne, les r\u00e9sultats des recherches de Lee sugg\u00e8rent que l'allongement de la cha\u00eene de carbone du ging\u00e9rol et du ging\u00e9rol semble entra\u00eener une diminution de leur activit\u00e9 contre Candida albicans.<\/p>\n<p>Notre groupe de recherche a d\u00e9couvert que l'extrait de gingembre a une activit\u00e9 antibact\u00e9rienne significative contre plus de 20 bact\u00e9ries pathog\u00e8nes, et que l'activit\u00e9 antibact\u00e9rienne de l'extrait est consid\u00e9rablement renforc\u00e9e apr\u00e8s la r\u00e9action photochimique. Au cours de l'\u00e9tude de l'activit\u00e9 antibact\u00e9rienne du gingembre, notre groupe de recherche a isol\u00e9 six compos\u00e9s de ging\u00e9rol. Afin d'explorer plus avant la relation entre l'activit\u00e9 antibact\u00e9rienne de ces compos\u00e9s et la longueur de la cha\u00eene grasse, nous avons men\u00e9 une \u00e9tude sur l'activit\u00e9 antibact\u00e9rienne de ces six compos\u00e9s de gingembre contre 15 souches pathog\u00e8nes, afin de trouver des mod\u00e8les parmi eux.<\/p>\n<p>Nous avons isol\u00e9 et identifi\u00e9 six compos\u00e9s ging\u00e9rols du gingembre, et effectu\u00e9 des tests d'activit\u00e9 antibact\u00e9rienne sur ces six compos\u00e9s. Sur cette base, nous avons explor\u00e9 de mani\u00e8re pr\u00e9liminaire la relation structure-activit\u00e9. Globalement, par rapport aux compos\u00e9s ging\u00e9rols 4, 5 et 6, les compos\u00e9s \u00e9noliques 1, 2 et 3 pr\u00e9sentent une activit\u00e9 inhibitrice contre un plus grand nombre de bact\u00e9ries Gram positives ; l'activit\u00e9 antibact\u00e9rienne des compos\u00e9s ging\u00e9rols 4 et 5 contre les bact\u00e9ries Gram n\u00e9gatives est sup\u00e9rieure \u00e0 celle des compos\u00e9s \u00e9noliques. D'apr\u00e8s les donn\u00e9es de nos tests antibact\u00e9riens et les r\u00e9sultats des recherches de Lee et al. une augmentation de la longueur de la cha\u00eene grasse des composants de type ging\u00e9rol peut entra\u00eener une diminution de l'activit\u00e9 antibact\u00e9rienne. Nos tests d'activit\u00e9 antibact\u00e9rienne avec Lee et al. ne ciblaient que les compos\u00e9s de ging\u00e9rol dont la longueur de la cha\u00eene grasse \u00e9tait de 5, 7 et 9 atomes de carbone. En ce qui concerne les cha\u00eenes grasses ayant moins de 5 ou plus de 9 atomes de carbone, une \u00e9tude plus approfondie est n\u00e9cessaire pour d\u00e9terminer si les r\u00e8gles susmentionn\u00e9es s'appliquent toujours.<br \/>\nLes ging\u00e9rols constituent une classe importante de composants antibact\u00e9riens dans le gingembre, et il vaut la peine d'explorer davantage les principes actifs antibact\u00e9riens potentiels ou les compos\u00e9s principaux \u00e0 partir de ces composants. Cette \u00e9tude peut jeter les bases de la recherche et du d\u00e9veloppement de compos\u00e9s de ging\u00e9rols ayant une activit\u00e9 antibact\u00e9rienne et de leurs m\u00e9canismes antibact\u00e9riens.<\/p>","protected":false},"excerpt":{"rendered":"<p>Study on the antibacterial activity of six gingerol compounds in ginger The excessive use of antibiotics has led to an increasingly serious problem of pathogen resistance.
