▎ Semaglutid Structure

▎ Semaglutid Kev Tshawb Fawb

Dab tsi yog qhov kev tshawb fawb keeb kwm ntawm Semaglutid?

Txoj kev loj hlob ntawm Semaglutid pib los ntawm kev tshawb fawb ntawm GLP-1's physiological teebmeem. Cov kws tshawb fawb tau tshwm sim los ntawm exendin-4 hauv lizard qaub ncaug los tsim thawj tiam GLP-1 receptor agonist. Txhawm rau nrhiav kev kho mob ntev dua, Semaglutid tau tsim los ntawm kev hloov kho tshuaj ntawm GLP-1 peptide saw, nrog rau kev sib ntxiv ntawm fatty acid chains kom ntev nws ib nrab-lub neej. Raws li kev tshawb fawb tau ua tiav, nws lub peev xwm hauv kev poob phaus thiab kev tiv thaiv kab mob plawv thiab kev kho mob kuj tau tshwm sim.

Semaglutid mechanism ntawm kev txiav txim yog dab tsi?

Kev tswj hwm ntawm insulin thiab glucagon secretion: 

Raws li GLP-1 receptor agonist (GLP-1 RA), Semaglutid txhawb nqa pancreatic β-hlwb kom tso cov tshuaj insulin thaum inhibiting α-hlwb los ntawm secreting glucagon. Tom qab noj mov, thaum cov ntshav qabzib nce siab, semaglutide khi rau GLP-1 receptors, ua kom cov kev taw qhia hauv qab los ua kom cov β hlwb tso tawm insulin, txhim kho lub cev kev noj qab haus huv thiab kev siv cov piam thaj, thiab txo cov ntshav qabzib. Los ntawm inhibiting glucagon secretion thiab txo cov piam thaj hauv siab, nws ntxiv stabilizes cov ntshav qabzib. Nyob rau hauv cov xwm txheej zoo li qub, lub cev tswj hwm cov ntshav qabzib hauv cov ntshav los ntawm kev tswj hwm qhov sib npaug ntawm insulin thiab glucagon. Semaglutid ua raws li qhov cuam tshuam ntawm GLP-1, ua kom zoo dua cov txheej txheem tswj hwm no ^[1,2].

Daim duab 1 Ntshav Qab Zib- thiab kev rog muaj feem cuam tshuam ntawm GLP-1 ^[3].

Inhibition ntawm hepatic gluconeogenesis: 

Semaglutid inhibits cov txheej txheem hepatic gluconeogenesis. Gluconeogenesis yog txoj hauv kev uas lub siab tsim cov piam thaj thaum lub sijhawm yoo mov lossis tshaib plab, tswj cov ntshav qabzib kom ruaj khov thaum cov ntshav qabzib qis. Txawm li cas los xij, hauv cov kab mob xws li ntshav qab zib mellitus, gluconeogenesis tuaj yeem ua haujlwm dhau, ua rau cov ntshav qabzib nce siab. Semaglutid ua rau txoj hauv kev cuam tshuam los txo cov kev qhia lossis kev ua haujlwm ntawm cov enzymes tseem ceeb gluconeogenesis, yog li txo qis cov piam thaj hauv siab thiab pab tswj cov ntshav qabzib ^[1].

Cov teebmeem ntawm lub zog metabolism thiab qab los noj mov: 

Semaglutid muaj kev tswj cov teebmeem ntawm lub zog metabolism thiab qab los noj mov. Nws txo qis kev noj qab haus huv, muaj peev xwm los ntawm kev ua haujlwm ntawm lub paj hlwb hauv nruab nrab los cuam tshuam kev noj qab haus huv cov chaw tswj hwm, ua rau muaj kev nkag siab ntawm kev puv thiab txo cov khoom noj. Tsis tas li ntawd, Semaglutid muaj qhov cuam tshuam me me rau kev siv hluav taws xob, feem ntau ua tiav kev tswj hwm qhov hnyav los ntawm kev txo qis zog, uas pab txo qhov hnyav rau cov neeg mob rog. Hauv kev sim, cov neeg mob siv Semaglutid feem ntau qhia txo qis qab los noj mov thiab poob phaus tom qab ^[1,4].

Cov txheej txheem muaj peev xwm ntawm kev ua haujlwm ntawm cov hlab plawv: Semaglutid tuaj yeem ua rau muaj txiaj ntsig zoo ntawm cov hlab plawv los ntawm ntau lub tshuab. Ntawm ib sab tes, nws tuaj yeem txo cov ntshav qabzib thiab lub cev hnyav, yog li txo qhov kev puas tsuaj los ntawm cov kab mob metabolic rau cov hlab plawv. Ntawm qhov tod tes, Semaglutid tuaj yeem ua ncaj qha rau ntawm cov hlab plawv, xws li los ntawm kev txhim kho vascular endothelial muaj nuj nqi, txo cov lus teb inflammatory thiab oxidative kev nyuaj siab, stabilizing atherosclerotic plaques, thiab txo cov kev pheej hmoo ntawm cov kab mob plawv. Cigrovski txoj kev tshawb fawb qhia tau hais tias Semaglutid tuaj yeem txhim kho txoj haujlwm ntawm vascular endothelial hlwb hauv secreting nitric oxide, txhim kho vasodilation, thiab tiv thaiv cov hlab plawv ^[5].

Qhov cuam tshuam ncaj qha rau kev ua haujlwm ntawm lub plawv: 

Cov kev tshawb fawb tsis ntev los no tau pom tias qhov mob hnyav rau Semaglutid tuaj yeem ua rau muaj kev cuam tshuam zoo ntawm cov tshuaj inotropic zoo rau tib neeg atrial trabeculae yam tsis tau ua rau muaj kev cuam tshuam rau arrhythmias. Cov nyhuv no tuaj yeem tshwm sim los ntawm kev nce sarcoplasmic reticulum Ca2 + reuptake, txhim kho atrial function, thiab tuav cov txiaj ntsig zoo rau cov tsos mob nyem rau cov neeg mob plawv. Hauv cov kev sim cuam tshuam, atrial trabeculae raug rau Semaglutid nthuav tawm qhov kev ua kom muaj zog contractile tsis muaj qhov nce hauv arrhythmias ^[6].

Dab tsi yog cov ntawv thov ntawm Semaglutid?

Rau ntshav qab zib hom 2: 

Semaglutid yog siv los kho mob ntshav qab zib hom 2. Txawm hais tias siv qhov ncauj lossis los ntawm kev txhaj tshuaj subcutaneous, nws txo qis hemoglobin A1c (HbA1c) qib ^[1].

Rau kev kho mob rog: 

Semaglutid qhia tau hais tias muaj txiaj ntsig zoo hauv kev kho mob rog. Cov kev sim tshuaj ntsuam xyuas qhia tias cov neeg mob rog tau kho nrog semaglutide tau poob ceeb thawj, nrog rau kev txo lub duav ncig, txhim kho cov ntshav siab, txo qis HbA1c, thiab txhim kho lipid profile (xws li txo tag nrho cov roj cholesterol, qis lipoprotein cholesterol, thiab triglycerides, thiab cov roj cholesterol ntau ntxiv). Nws cov txiaj ntsig poob phaus yog qhov zoo tshaj rau cov placebos thiab lwm yam tshuaj poob phaus, ua tau raws li cov qauv tsim los ntawm EMA thiab FDA rau cov tshuaj poob phaus, thiab muab cov kev xaiv kho tshiab rau cov neeg mob rog ^[1,2].

Txo kev pheej hmoo ntawm kab mob plawv: 

Rau cov neeg laus uas muaj ntshav qab zib hom 2 thiab paub kab mob plawv, Semaglutid tuaj yeem txo qhov kev pheej hmoo ntawm cov kab mob plawv. Cov kev tshawb fawb xws li SUSTAIN 6 thiab PIONEER 6 kev sim ua tau pom qhov tsis zoo thiab kev nyab xeeb ntawm subcutaneous thiab qhov ncauj Semaglutid hauv plawv plawv, thiab SELECT sim ntxiv tau lees paub nws cov txiaj ntsig zoo hauv kev txhim kho cov txiaj ntsig ntawm cov hlab plawv, pab txo qis kev pheej hmoo ntawm cov kab mob plawv ^[1].

Kev tiv thaiv rau lub raum: 

Nyob rau hauv tus qauv nas ntawm lub raum ischemia-reperfusion raug mob, Semaglutid qhia txog kev tiv thaiv lub raum. Nws txo cov qib ntawm cov kab mob inflammatory xws li qog necrosis factor-α (TNF-α) thiab nws cov receptor, interleukin-6 (IL-6), txo F8 prostaglandin ntau lawm, nce PI3K thiab AKT qib hauv lub raum cov ntaub so ntswg, thiab alleviates lub raum raug mob, qhia tias Semaglutid tej zaum yuav muaj kev kho mob raum mob ^[7]..
