Mokhoa oa ketso ea urolithin A le B
● Urolithin A e khothalletsa mitophagy
Mitophagy ke mofuta o le mong oa autophagy o thusang ho tlosa mitochondrial e senyehileng bakeng sa ts'ebetso ea bona e nepahetseng. Autophagy e bua ka ts'ebetso e akaretsang eo litaba tsa cytoplasmic li nyenyefalitsoeng 'me ka lebaka leo li phetisetsoang ha li-mitophag ke mokhoa o nyarosang le oa ho nchafatsa oa mitochondria.
Nakong ea botsofali ho fokotseha ha autophagy ke karolo e 'ngoe e lebisang ho fokotseheng ha ts'ebetso ea mitochondrial. Ho feta moo, khatello ea mali e ka lebisa ho ho itšireletsa tlaase. Urolithin A na le bokhoni ba ho felisa mitochondria e senyehileng ka ho khetha autophagy.
● Mefuta e thibelang likokoana-hloko
Ho imeloa kelellong ho etsahala ha ho ba le ho leka-lekana pakeng tsa li-radicals tsa mahala le antioxidant 'meleng. Li-radicals tsena tse sa lefelloeng haholo hangata li amahanngoa le mafu a mangata a sa foleng a kang mafu a pelo, lefu la tsoekere le mofets'e.
Urolithins A le B li bonts'a litlamorao tsa antioxidant ka bokhoni ba tsona ba ho fokotsa li-radicals tsa mahala mme ka ho khetheha maemo a kenang a oksijene a maiketsetso a oksijene (ROS) hape a thibela lipid peroxidation mefuteng e meng ea lisele.
Ho feta moo, li-urolithin li khona ho thibela li-enzyme tse nang le oxidizing, ho kenyelletsa le monoamine oxidase A le tyrosinase.
● Lintho tse thibelang ho ruruha
Ho ruruha ke mokhoa oa tlhaho oo 'mele ea rona e loantšang ntho efe kapa efe e oeleng joalo ka ts'oaetso, likotsi le likokoana-hloko. Leha ho le joalo, ho ruruha ho sa foleng ho ka ba kotsi 'meleng kaha hona ho amahanngoa le mathata a fapaneng a kang asma, mathata a pelo le mofetše. Ho ruruha ho sa foleng ho ka hlaha ka lebaka la ho ruruha ho matla ho sa phekoleheng, tšoaetso kapa esita le methapo ea mmele e sa lefelloeng.
Urolithins A le B e bonts'a thepa e khahlanong le ho ruruha ka ho thibela tlhahiso ea nitric oxide. Ka ho khetheha ba thibela protheine ea nitric oxide synthase (iNOS) ea inducible le polelo ea mRNA e ikarabellang bakeng sa ho ruruha.
● Litla-morao tse thibelang likokoana-hloko
Likokoana-hloko tse kenyeletsang libaktheria, li-fungus le likokoana-hloko li etsahala ka tlhaho tikolohong ea 'mele oa motho. Le ha ho le joalo, likokoana-hloko tse 'maloa tse bitsoang li-pathogen li ka baka mafu a tšoaetsanoang joalo ka ntaramane, semola le mala.
Urolithin A le B li khona ho bonts'a ts'ebetso ea antimicrobial ka ho thibela sensor ea quorum. Sensor ea Quorum ke mokhoa oa puisano oa baktheria o thusang libaktheria ho bona le ho laola lits'ebetso tse amanang le ts'oaetso joalo ka virilence le motility.
● Ho thibela protein glycation
Glycation e bua ka karolo e se nang enzymatic ea tsoekere ho lipid kapa protheine. Ke sehlahisoa sa bohlokoa sa lefu la tsoekere le mafu a mang hammoho le botsofali.
Ho ba le protheine e phahameng ke phello ea bobeli ea hyperglycemia e na le karolo e kholo mathateng a amanang le pelo le methapo e kang lefu la tsoekere le lefu la Alzheimer's.
Urolithin A le B li na le thepa ea anti-glycative e itšetlehileng ka litekanyetso tse ikemetseng mesebetsing ea bona ea antioxidant.
Melemo ea Urolithin A
(1) E ka lelefatsa nako ea bophelo
Urolithin A e kenyelletsa sebopeho ka ho khetha ka boomo ho tlosa mitochondria e senyehileng. Sena se boetse se netefatsa hore li-mitochondria li sebetsa hantle hape. Mitochondria hangata e senyeha ka lilemo le ka lebaka la khatello ea maikutlo. Ho tlosa mitochondria e senyehileng ho bapala karolo ea ho atolosa nako ea bophelo.
Thutong ea liboko, urolithin Tlatsetso e sebelisitsoeng ho 50 µM ho tloha sethaleng sa lehe ho fihlela lefung e fumanoe e le ho eketsa bophelo ba bona ka 45.4%.
Phuputsong e 'ngoe e entsoeng ka 2019 ho sebelisoa li-fibroblast tsa batho tse senescent, urolithin A supplement e fumanoe e bonts'a bokhoni ba ho loants'a botsofali. E khonne ho eketsa mofuta oa 1 collagen expression hape e fokotsa polelo ea matrix metalloproteinase 1.
Boithuto bo nyane ba motho bo boetse bo bonts'a hore UA e khonne ho ntlafatsa ts'ebetso ea mitochondrial le bophelo bo botle ba masapo ho batho ba tsofetseng ha ba fanoa ka molomo ho 500-1000mg nako ea libeke tse 'ne.
(2) Thusa ho thibela mofetše oa senya
Li-urolithin le moetapele oa tsona, ellagitannins, li na le thepa ea anti-cancer. Ba khona ho thibela bongata ba lisele tsa mofetše ka ho potoloha le ho potoloha ha lisele. Apoptosis e bua ka lefu le hlophisitsoeng leo ho lona 'mele o felisang lisele tse nang le mofetše le lisele tse ling tse nang le tšoaetso.
Phuputsong ea litoeba tse kentsoeng ka lisele tsa mofetše oa batho, li-ellagitannins metabolites (Urolithin A) li fumanoe li thibela kholo ea mofets'e oa lefu la senya. Phuputso e boetse e tlaleha ho phahama ho hoholo ha metabolites ka har'a tšoelesa ea senya, lera le mala.
(3) Ntlafatso ea kelello
Urolithin A e khona ho sireletsa li-neuron ho tloha lefung hape e ka baka le neurogeneis ka ho saena le ho tšoaetsana le mats'oafo.
Phuputsong ea litoeba tse nang le bothata ba ho lebala, urolithin A e fumanoe e ntlafatsa ho senyeha hoa kelello le ho sireletsa li-neuron ho tloha apoptosis. Sena se fana ka maikutlo a hore UA e ka sebelisoa ho phekola lefu la Alzheimer's (AD).
(4) Bokhoni bo khahlanong le botenya
Patlisiso e bonts'a hore li-ellagitannins li khona ho thibela ho bokellana ha lipid le li-tag tsa adipogenic tse kang protheine ea pele ea kholo ea ho hola 2 hammoho le protheine e tlamang mats'oafo ka ho ts'oaroa ha cell cell.
Urolithin A e fumanoe ka ho khetheha ho ntlafatsa kutloisiso ea insulin kahoo e thibela nts'etsopele ea botenya.
Phuputsong ea litoeba tse nang le botenya bo feteletseng, urolithin A tlatselletso e fumanoe ho thibela botenya bo bakoang ke ho ja le ho senyeha hoa metabolic ka litoeba. Phuputso e bontšitse hore kalafo ea UA e eketsa tšebeliso ea matla ka hona boima ba mmele o tlase.
Mehloli ea lijo ea Urolithin A le B
Li-urolithin ha li tsejoe ho fumaneha ka tlhaho mehloling efe kapa efe ea lijo. Ke sehlahisoa sa phetoho ea li-ellagic acid tse nkiloeng ho ellagitannins. Ellagitannins e fetoloa li-ellagic acid ke gut microbiota mme ellagic acid e fetoloa hape ka metabolites ea eona (urolithins) ka mala.
Li-ellagitannins li hlaha ka tlhaho mehloling ea lijo joalo ka likharenate, monokotsoai o kenyelletsang fragole, tse tala, monokotšoai le monokotšoai, morara oa muscadine, lialmonde, li-guava, tee le linate tse kang walnuts le li-chestnut hammoho le lino tse tsofetseng tsa oak mohlala veine e khubelu le whisky Meqomo ea eike.
Ka hona re ka phethela lijo tsa urolithin A le lijo tsa urolithin B ke lijo tse nang le ellagitannin. Ke habohlokoa ho hlokomela hore ellagitannin bioavailability e na le moeli ha methabolite ea eona ea bobeli (urolithins) e fumaneha habonolo.
Metsoako ea Urolithins le tlhahiso li fapana haholo har'a batho ho tloha ha phetoho e tsoang ho ellagitannins e its'etleha ka microbiota ka maleng. Ho na le libaktheria tse ikhethang tse amehang phetohong ena 'me lia fapana hara batho moo ba bang ba nang le microbiota e phahameng, e tlase kapa e se nang eona. Mehloli ea lijo le eona ea fapana maemong a ellagitannins. Kahoo melemo e ka bang teng ea ellagitannins e fapana ho ea ka batho.
Lisebelisoa tsa Urolithin A le B
Li-supplements tsa Urolithin A hammoho le li-supplements tsa Urolithin B li fumaneha habonolo 'marakeng joalo ka mohloli oa lijo tse nang le ellagitannin. Urolithin A li-supplement le tsona li fumaneha habonolo. Haholo-holo likharenate tse tlatselletsang li rekisitsoe haholo mme li sebelisitsoe ka katleho. Lisebelisoa tsena li entsoe ka litholoana kapa linate ebe li etsoa ka mokelikeli kapa phofo.
Ka lebaka la phapang ea li-ellagitannins tse kenang lijong tse fapaneng, bareki ba urolithin ba e reka ho nahanisisa ka mohloli oa lijo. Ho joalo le ha o fumana phofo ea urolithin B kapa litlatsetso tsa metsi.
Lithuto tse 'maloa tsa bongaka tse entsoeng ka urolithin A phofo kapa B ha li so ka li tlaleha litla-morao tse tsoang ho tsamaiso ea li-supplement tsena.
