1. Kev faib ua pawg

Los ntawm kev xav ntawm cov khoom siv thiab kev siv, Mazdutide raw khoom peptides feem ntau tuaj yeem muab faib ua pawg hauv qab no:

Thawj qeb yog kev tshawb fawb -qib Mazdutide peptides, nrog rau kev purity feem ntau nyob ib ncig ntawm 95%, feem ntau yog siv rau kev soj ntsuam thaum ntxov, nyob rau hauv vitro kev tshawb fawb, thiab cov txheej txheem validation.

Cov qeb thib ob yog siab -kev tshawb fawb purity- qib peptides, nrog purity mus txog 98% lossis txawm tias 99%, haum rau kev tshawb fawb pharmacodynamic, pharmacokinetic, thiab kev ruaj ntseg, nrog rau cov kev xav tau siab rau impurity profiles thiab sequence integrity.

Cov qeb thib peb yog kev cai-ua lossis txheej txheem teev- nce peptides, hais txog kev sib luag ntawm cov khoom sib xws, kev pom zoo ntawm cov qauv, thiab kev taug qab, feem ntau siv rau kev ua kom zoo, ua ntej- kev tshawb fawb txog kev tsim, thiab kev sau npe- cuam tshuam txog kev txhawb nqa.

2. Molecular Structure thiab Design yam ntxwv

Mazdutide yog qhov nruab nrab -ntev polypeptide molecule. Nws cov amino acid sequence yog optimized raws li tej yam ntuj tso cov tshuaj hormones, thiab nws cov tsis kam mus rau enzymatic degradation yog txhim khu kev qha los ntawm kev hloov kho ntawm cov chaw tseem ceeb.

Cov molecule no feem ntau suav nrog fatty acid sab chains lossis cov amino acid residues los txhim kho nws txoj kev sib raug zoo rau cov ntshav plasma proteins, yog li ncua nws lub sijhawm ua haujlwm hauv vivo. Cov qauv ib txhij koom nrog kev sib raug zoo rau ob qho tib si GLP-1 thiab GCGR receptors, ua rau nws yog ib qho piv txwv ntawm "cov qauv kev ua haujlwm zoo tshaj plaws" peptide.

3. Physicochemical Properties

Lub cev, Mazdutide yog amorphous lossis microcrystalline khoom, ruaj khov ntawm chav tsev kub.

Nws qhov hnyav molecular poob rau hauv ntau yam rau cov tshuaj peptide; qhov tseeb molecular hnyav tuaj yeem lees paub los ntawm huab hwm coj spectrometry (ESI-MS).

Nws solubility yog raws li nram no:

Nws pom zoo solubility hauv dej thiab tsis muaj zog acidic tsis daws teeb meem;

Nws yog qhov tseem ceeb insoluble lossis tsuas yog me ntsis soluble hauv cov kuab tshuaj organic.

Nws cov ntsiab lus isoelectric feem ntau yog nruab nrab lossis tsis muaj zog, uas yog ib qho txiaj ntsig zoo rau kev xaiv cov khoom tsis sib xws thiab cov qauv tsim.

4. Xim thiab tsos yam ntxwv

Siab - zoo Mazdutide raw khoom peptides feem ntau yog dawb los yog tawm -cov hmoov dawb lyophilized nrog cov ntaub ntawv xoob thiab zoo ib yam.

Xim yog ib qho tseem ceeb ntawm kev pom ntawm cov khoom siv raw khoom zoo: Cov xim dawb dawb, tsis pom cov impurities, feem ntau qhia tau tias muaj kev tswj xyuas zoo thaum lub sij hawm sib xyaw thiab ua kom huv si;

Ib qho pom daj lossis greyish xim tuaj yeem cuam tshuam rau oxidation, degradation, lossis seem impurities.

High- cov khoom lag luam zoo yuav tsum nthuav tawm raws li qhov tseeb lossis nyob ze - cov kev daws teeb meem meej tsis muaj nag lossis daus tom qab rov tsim dua.

5. Qhov zoo thiab cov yam ntxwv tseem ceeb

Mazdutide, raws li qib siab - zoo peptide, muaj ntau yam zoo:

Ua ntej, nws cov qauv tsim kho siab heev txhim kho nws cov txiaj ntsig kev noj qab haus huv tag nrho los ntawm kev siv dual - lub hom phiaj;

Qhov thib ob, nws nthuav tawm qhov kev ruaj ntseg molecular siab thiab tiv taus ntau dua rau hauv vivo enzymatic hydrolysis piv rau ntuj peptides;

Thib peb, cov khoom siv raw peptides qhia tau zoo batch-rau-batch sib xws, yooj yim rau kev tshawb fawb tus qauv thiab kev tswj kom zoo;

Plaub, nws yog qhov tsim nyog rau ntau yam kev xa tshuaj thiab kev tshawb nrhiav cov txheej txheem, muab kev yooj yim rau kev txhim kho tom ntej.

Los ntawm kev pom cov khoom siv raw, kev loj hlob thiab scalability ntawm nws cov txheej txheem hluavtaws kuj tseem ceeb heev.

6. Txheej txheem cej luam ntawm Synthesis thiab Purification txheej txheem

Mazdutide feem ntau yog npaj siv cov khoom siv -theem peptide synthesis thev naus laus zis, ua kom tiav cov pob txha caj qaum los ntawm kev sib txuas ntawm cov amino acid stepwise.

Tom qab kev sib txuas, deprotection, cleavage, thiab multi-pab kom huv yog yuav tsum tau, feem ntau yog siv reversed-theem siab-kev ua tau zoo kua chromatography (RP-HPLC) raws li cov txheej txheem tseem ceeb.

Cov khoom kawg yog lyophilized kom tau txais daim ntawv hmoov ruaj khov. Tag nrho cov txheej txheem tso siab rau qhov zoo ntawm cov amino acids raw, coupling efficiency, thiab purification tej yam kev mob.

7. Cov Ntsiab Cai Tswj Xyuas Zoo

Siab- cov ntaub ntawv zoo Mazdutide yuav tsum dhau ntau qhov kev xeem, suav nrog:
