    XI 'IB LESEN BIOTECHNOLOGY CO., LTD.   tshwjxeeb hauv kaum xyoo ntawm kev cog ntoo thiab kev lag luam tawm, muab cov neeg siv khoom zoo, organic, ntuj, zoo nqe ntawm ntau yam kev cog ntoo, txiv hmab txiv ntoo thiab zaub hmoov, thiab cov tshuaj pleev ib ce, cov ntaub ntawv tshuaj raw.

    L-DOPA yog ib qho amino acid uas tau tsim thiab siv los ua ib feem ntawm lub cev ntawm tib neeg, qee cov tsiaj, thiab nroj tsuag. Qee cov tsiaj txhu thiab tib neeg ua nws ntawm biosynthesis los ntawm cov amino acid L-tyrosine. L-DOPA yog tus ua ntej rau cov neurotransmitters dopamine, norepinephrine (noradrenaline), thiab epinephrine (adrenaline) collectively hu ua catecholamines. Tsis tas li ntawd, L-DOPA nws tus kheej cuam tshuam txog cov hlwb thiab cov hlwb hauv CNS. L-DOPA tuaj yeem tsim tau thiab nyob rau hauv nws daim ntawv dawb yog muag raws li ib qho kev siv tshuaj tiv thaiv psychoactive nrog INN levodopa; cov npe muaj xws li Sinemet, Pharmacopeia, Atamet, Stalevo, Madopar, thiab Prolopa. Ua ib qho tshuaj, nws yog siv rau hauv kev kho mob ntawm Parkinson tus kab mob thiab dopamine-responsive dystonia.

    L-DOPA muaj ib tug neeg ua haujlwm nrog cov lus sib tw sib tw, D-DOPA. Raws li muaj tseeb rau ntau tus qauv, lub cev tib neeg tsim tawm ib qho ntawm cov isomers (L-DOPA daim ntawv). Cov purity enantiomeric ntawm L-DOPA tej zaum yuav soj ntsuam los ntawm qhov kev txiav txim siab ntawm qhov kev hloov ua piv txwv los ntawm chiral nyias-txheej chromatography (chiral TLC).

    Kev khiav dej num ntawm Levodopa:

    L-DOPA hla txoj kev tiv thaiv ntshav-hlwb barrier, whereas dopamine xwb tsis tuaj yeem. Li no, L-DOPA yog siv los ua kom dopamine ntau nyob rau hauv kev kho mob ntawm Parkinson tus kab mob thiab dopamine-responsive dystonia. Txoj kev kho no tau ua thiab siv tau los ntawm George Cotzias thiab nws cov neeg ua hauj lwm, uas lawv yeej 1969 Laser Prize. Thaum L-DOPA tau nkag mus rau hauv lub hauv paus paj hlwb, nws hloov dua siab tshiab rau hauv dopamine los ntawm enzyme aromatic L-amino acid decarboxylase, los yog DOPA decarboxylase. Cov tshuaj Pyridoxal phosphate (vitamin B6) yog ib qho cofactor uas yuav tsum tau ua rau cov tshuaj tiv thaiv no, thiab tej zaum yuav tau ua nrog rau L-DOPA, feem ntau hauv daim ntawv ntawm pyridoxine.

    1. Txhim kho libido thiab kev sib daj sib deev, nce zog zog;

    2. Ua kom zoo dua qub thiab muaj kev noj qab nyob zoo, ua kom zoo nkauj tawv nqaij thiab tsos nqaij daim tawv;

    3. Txhim kho kev pw tsaug zog (txhawb nqa pw tsaug zog tsaug zog), txo lub cev rog thiab tsis tshua muaj cellulite.

    4. L-dopa (3,4-dihydroxy-L-phenylalanine) yog ib qho muaj tshwm sim ntawm cov amino acid nyob hauv cov zaub mov thiab ua los ntawm L-Tyrosine hauv tib neeg lub cev.

    5. L-dopa yog hloov mus rau hauv dopamine hauv lub hlwb thiab lub cev. Nws yog muag raws li kev noj haus ntxiv thiab ua ib hom tshuaj siv tshuaj hauv Tebchaws Meskas.

    6. Hauv kev siv tshuaj kho, Levodopa (INN) yog tswj hwm kev tswj hwm ntawm Parkinson's disease thiab dopa-responsive dystonia.

    7. Nws kuj yog siv los ua cov khoom siv hauv marine siv los ntawm pelagic lub neej.
