Koj puas tau xav tias yuav ua li cas lub ntuj tsim los ntawm vitamin B₃ metabolism tuaj yeem cuam tshuam rau vascular noj qab haus huv, kev ua kom muaj zog, thiab mob? Cia peb nkag siab txog kev tshawb fawb thiab kev siv peev xwm ntawm 1-methylnicotinamide (1-MNA) - cov metabolite endogenous tau txais kev saib xyuas hauv kev tshawb fawb biomedical niaj hnub.
Dab tsi yog 1 methylnicotinamide Chloride
1 Methylnicotinamide Chloride Hmoov(1-MNA) yog ib qho me me-molecule endogenous tshuaj tau los ntawm cov metabolism ntawm niacin (vitamin B₃). Nws lub npe tshuaj yog N¹-methylnicotinamide, thiab nws belongs rau methylated metabolites ntawm nicotinamide. Nicotinamide yog methylated siv S-adenosylmethionine (SAM) ua methyl pub dawb raws li kev ua ntawm nicotinamide N-methyltransferase (NNMT). Nws yog ib txwm muaj nyob rau hauv lub cev; nws kuj muaj nyob rau hauv cov ntshav thiab zis. Nws feem ntau yog siv los ua biomarker rau qib niacin thiab NNMT kev ua. Nws tau raug tshaj tawm tias muaj kev tiv thaiv kab mob thiab kev tiv thaiv vascular, nrog rau cov teebmeem ntawm endothelial muaj nuj nqi thiab nitric oxide signaling.
Nws yog txuam nrog lub zog metabolism thiab methylation tshuav nyiaj li cas, pab txhawb kev tswj cov metabolism. Cov chaw tshawb fawb muaj xws li kev noj qab haus huv ntawm cov hlab plawv, cov kab mob metabolic, lub raum ua haujlwm, thiab cov txheej txheem metabolic ntawm cov tsos mob ntawm tes (vim hloov pauv NNMT kev ua haujlwm). Nco ntsoov tias nws tsis yog vitamin B₃ nws tus kheej, thiab nws tsis ncaj qha rau cov teebmeem ntawm NAD⁺. Nws kuj tsis yog stimulant lossis hormone. Nws yog ib qho tshwm sim metabolite ntawm nicotinic acid, ua ib qho txiaj ntsig metabolic qhia thiab muaj cov haujlwm ua haujlwm ntawm lub cev. Yog tias koj tseem xav tau 1 methylnicotinamide Chloride, thov koj xav tiv tauj peb ntawm Xi'an Sonwu; peb yuav zoo siab los muab kev pabcuam rau koj.
Cov txiaj ntsig ntawm 1 methylnicotinamide Chloride yog dab tsi
Cov lus pom zoo hais txog cov txiaj ntsig muaj peev xwm ntawm 1 methylnicotinamide Chloride (1-MNA) supplementation feem ntau yog raws li kev tshawb fawb tsiaj, kev tshawb fawb tib neeg tsawg, thiab kev tshawb nrhiav tshuab tshiab. Cov ntaub ntawv pov thawj muaj zog hauv cov neeg noj qab haus huv tseem muaj tsawg heev.
Cov txiaj ntsig muaj peev xwm nyob hauv kev tshawb nrhiav
1. Cov kab mob plawv thiab cov hlab plawv
1-MNA tuaj yeem txhim kho endothelial (vascular hauv ob sab phlu) ua haujlwm los ntawm kev nce nitric oxide (NO) bioavailability, yog li txhawb vasodilation thiab noj qab haus huv cov ntshav txaus. Cov nyhuv no tau pom nyob rau hauv cov tsiaj qauv ntawm vascular dysfunction. Nws kuj tseem tuaj yeem txhawb kev tsim cov prostacyclin (PGI₂), uas pab inhibit platelet aggregation thiab tej zaum yuav muaj antithrombotic (anticoagulant).
2. Cov tshuaj tiv thaiv -inflammatory teebmeem
Cov kev tshawb fawb tau pom tias 1-MNA tuaj yeem txo cov teeb meem inflammatory thiab cytokines (xws li TNF- thiab IL-6) thiab tuaj yeem pab tiv thaiv cov kab mob neuroinflammation thiab kab mob hauv cov tsiaj ua qauv.
3. Ua kom muaj zog tiv thaiv kab mob thiab lub zog metabolism
Hauv kev tshawb fawb tsiaj (piv txwv li, cov nas mob ntshav qab zib), 1-MNA txhim kho kev ua kom lub cev muaj zog thiab tuaj yeem txhawb nqa lub zog metabolism hauv kev tawm dag zog. Ib txoj kev tshawb fawb me me ntawm tib neeg (thaum lub sijhawm COVID-19 rov qab los) tau qhia tias kev noj txhua hnub ntawm kwv yees li 58 mg ntawm 1-MNA tuaj yeem txhim kho kev tawm dag zog thiab txo qis qaug zog piv nrog tsis noj tshuaj, tab sis cov ntaub ntawv yog thawj zaug.
4. Cov nyhuv Neuroprotective (Kev tshawb fawb txog kev kho mob)
Hauv cov kev tshawb fawb nas, 1-MNA txo qis kev puas hlwb kev puas hlwb thiab yuav pab tiv thaiv cov neurons thiab txo cov hlwb apoptosis (cell tuag).
5. Metabolism thiab NAD-Txog Txoj Kev
Vim tias 1-MNA koom nrog hauv niacin metabolism, cov kws tshawb fawb tab tom tshawb nrhiav nws cov teebmeem ntawm cov cellular NAD⁺ metabolism thiab txoj kev sirtuin (txuas nrog lub zog metabolism thiab kev laus). Txawm li cas los xij, cov txheej txheem no tseem tsis tau lees paub tag nrho hauv tib neeg.
Raws li kev tshawb fawb uas twb muaj lawm, cov khoom no qhia tau hais tias muaj txiaj ntsig kev noj qab haus huv thoob plaws ntau thaj chaw, tab sis cov pov thawj tseem feem ntau nyob rau theem pib. Hais txog kev noj qab haus huv ntawm cov hlab plawv, nws tuaj yeem txhim kho endothelial muaj nuj nqi thiab muaj qee yam tshuaj tiv thaiv kab mob, tab sis tam sim no tsuas yog txhawb nqa los ntawm cov tsiaj ua ntej thiab kev tshawb fawb tib neeg. Hais txog nws cov tshuaj tiv thaiv- mob, kev tshawb fawb hauv tsev kho mob tau pom tias nws tuaj yeem txo cov qib pro- cov cim kab mob. Thaum ntxov me me -scale tib neeg kev sim siab qhia tias nws tuaj yeem txhim kho kev ua haujlwm siab ntev, tshwj xeeb yog cuam tshuam nrog kev tawm dag zog thiab qaug zog. Cov kev tshawb fawb tsiaj kuj pom tias nws muaj cov teebmeem neuroprotective hauv cov qauv mob. Tsis tas li ntawd, raws li kev tshawb fawb txog kev siv tshuab thiab tsiaj txhu, nws tuaj yeem tswj hwm NAD + txoj kev metabolic. Zuag qhia tag nrho, cov txiaj ntsig muaj peev xwm no tseem yuav tsum tau muaj kev lees paub ntxiv los ntawm kev kawm siab dua -kev soj ntsuam zoo.
1 methylnicotinamide Chloride sai npaum li cas
Lub sijhawm pib ntawm 1 methylnicotinamide Chloride (1-MNA) yog nyob ntawm qhov tshwj xeeb ua thiab kev tswj hwm koj tau hais txog. Raws li pharmacokinetics thiab cov ntaub ntawv tib neeg / tsiaj txhu uas twb muaj lawm:
Kev nqus thiab ncig: nqus sai sai tom qab kev tswj hwm, kuaj pom hauv cov ntshav li ntawm 30-60 feeb. Peak plasma concentration tshwm sim kwv yees li 1-2 teev tom qab kev tswj hwm. Tshem tawm ib nrab-lub neej: luv (ntau teev); yog li ntawd, nws tsis accumulate heev.
Cov teebmeem ua haujlwm (cov teebmeem tshwm sim los ntawm tib neeg lub cev):
1. Cov teebmeem ntawm vascular/endothelial: Mechanistic teebmeem ntawm nitric oxide signaling pathway thiab prostacyclin (PGI₂) pib tshwm nyob rau hauv lub cellular theem nyob rau hauv lub sij hawm. Yog tias ntsuas kev txhim kho hauv kev ua haujlwm endothelial tau pom, cov no feem ntau yuav raug kuaj pom tom qab ob peb hnub mus rau 1-2 lub lis piam ntawm kev tswj hwm txhua hnub.
2. Kev ua kom muaj zog / qaug zog: Ib qho kev qhia dav dav rau tib neeg me me (post-COVID-19 qaug zog) tau pom tias muaj kev txhim kho hauv kev tawm dag zog / qaug zog tom qab noj tshuaj txhua hnub rau 2-4 lub lis piam. 3. Cov tshuaj tiv thaiv kab mob: Molecular anti-inflammatory signaling tuaj yeem pib siv tsis tu ncua nyob rau hauv ob peb hnub, tab sis tseem ceeb hloov pauv.
Nws cov txheej txheem ntawm kev ua txawv ntawm cov caffeine lossis lwm yam stimulants (nws tsis tsim cov teebmeem sai sai), thiab nws tsis nce NAD⁺ tam sim ntawd xws li NR lossis NMN; yog li ntawd, nws tsis xav tias yuav txhim kho kev ua kis las lossis lub siab xav tam sim ntawd. Yog li, nws cov teebmeem yog maj mam es tsis yog tam sim. Yog tias cov teebmeem tshwm sim, lawv feem ntau pom tom qab ob peb hnub mus rau lub lis piam ntawm kev siv txhua hnub, tsis yog tam sim ntawd tom qab ib koob tshuaj.
