Cov khoom no tseem tsis tau pom zoo rau kev siv tshuaj thiab tsuas yog siv rau kev tshawb fawb. Peb txais tos cov lus nug.
Leuprolide Acetate CAS 1926163-25-8|classic peptide, qib tshawb fawb muaj, kilograms muaj
Ua leuprolide R & D cov neeg, ntau dua los yog tsawg dua tau ntsib xws li kev txaj muag: kev sim me me kom pom qee qhov peptide yooj yim, mus rau qhov ntsuas ntsuas -nce, tus neeg muag khoom qub tau hais tias tsis tuaj yeem ua ntau ntau, lossis qhov zoo ntawm batch drifted ntau dhau, impurity profiles tsis tuaj yeem sib phim, cov txheej txheem tseem tsis tau khiav tawm ntawm qhov chaw yuav hloov. Peb tau sib tsoo ntawm hom no rau ntau tshaj kaum xyoo, los ntawm milligrams mus rau kilograms ntawm kev tsim muaj peev xwm yog los ntawm, txheej txheem stability, impurity profiles clear, tag nrho cov ntaub ntawv.
Kom meej meej: peb leuprolide tsis tau raug foob rau kev siv tshuaj, nws tsis tuaj yeem muag raws li API, thiab tsis tuaj yeem muab ncaj qha rau tib neeg. Txawm li cas los xij, yog tias koj tab tom ua ua ntej - kev tshawb fawb ntawm cov tshuaj generic, txheej txheem ntawm microsphere formulation, kev txhim kho ntawm impurity tswj, los yog xav tau ib tug loj npaum li cas ntawm leuprolide los khiav lub pilot test, ces peb cov kev tshawb fawb - cov khoom qib tsuas yog rau txoj kev - tsis tsuas yog peb muaj peev xwm muab ib tug me me mus sib hais ntawm ob peb milligrams, tab sis kuj yuav siv sij hawm ib tug ob peb milligrams loj. nruab nrab.
Leuprolide yog dab tsi thiab nws siv li cas hauv R & D?
Leuprolide Acetate CAS 1926163-25-8 (leuprolide acetate) yog 9-peptide, GnRH agonist uas yog siv los kho cov kab mob ntawm cov tshuaj hormones xws li mob qog noj ntshav, mob cancer mis, thiab endometriosis. Hauv R & D lub voj voog, nws tau raug tsom rau peb lub laj thawj tseem ceeb:
Generic drug development:ob peb domestic manufacturers tau qhia, yog ib tug classic ntau yam.
Kev tshawb nrhiav microsphere formulation:Vim tias qhov kev ua haujlwm siab ntawm qhov ntev - cov qauv ua yeeb yam, leuprolide feem ntau yog siv los ua qauv tshuaj, xws li kev xyaum lossis kev tshawb fawb.
Impurity thiab kev kawm zoo:Nws cov khoom degradation thiab cov txheej txheem impurities yuav tsum muaj siab purity tswj rau txoj kev thiab kev tswj kom zoo.
Peb leuprolide yog qhov chaw los txhawb cov xwm txheej R&D no - tsis yog rau kev kho mob, tab sis yeej txaus rau R&D, thiab nws tuaj yeem khaws los ntawm milligrams mus rau kilograms.
Peb tuaj yeem ua dab tsi hauv hom no?
1. Kilograms ntawm lub peev xwm, tsis muaj kev hloov pauv ntawm cov neeg ua haujlwm rau kev ntsuas ntsuas - nce
Ntau qhov kev tshawb fawb-qib cov neeg muag khoom tsuas yog ua me me xwb, thiab thaum koj xav tau kaum grams lossis ntau pua grams, lawv co taub hau. Peb sib txawv hauv leuprolide: kev sim me me, kev sim ntsuas, ntsuas - nce, siv tib txheej txheej txheej txheem logic. Tam sim no peb tuaj yeem muab cov khoom hnyav hnyav, thiab peb tuaj yeem tswj cov purity, impurity profile thiab tawm los ntawm cov khoom siv. Yog tias koj tab tom ua qhov kev sim ntsuas ntawm microsphere formulation, los yog npaj khiav peb batch rau validation, koj tsis tas yuav txhawj txog cov ntaub ntawv raw lawm.
2. Txaus siab ntshiab, nrog rau qhov tseeb impurity profile
Peb siv cov khoom siv-theem synthesis, Fmoc lub tswv yim, thiab ntau-kauj ruam npaj HPLC rau kev ua kom huv. qhov purity ntawm cov khoom tsis tu ncua yog ntau dua lossis sib npaug li 98%, thiab cov khoom tseem ceeb tuaj yeem ua tau ntau dua lossis sib npaug li 99% lossis siab dua. Txhua pawg ntawm COA, nrog HPLC thiab MS graphs. Rau cov khoom uas xav tau impurity profiling, peb tuaj yeem muab cov npe ua tiav ntawm impurities paub - oxidized impurities, deamidated impurities, ploj peptides, dimers - peb muaj cov ntaub ntawv, thiab peb tuaj yeem muab kev tswj hwm.
3. Cov ntaub ntawv corroboration, npaj rau kev siv
Qhov tsis muaj cov ntaub ntawv pov thawj ntawm cov qauv hauv kev xa tawm yog mob taub hau rau ntau tus kws tshawb fawb. Thaum peb ua leuprolide, peb khaws cov ntaub ntawv ntawm nuclear magnetic resonance (NMR), infrared resonance (IR) thiab siab daws teeb meem loj spectrometry (HRMS). Yog tias koj xav tau, peb yuav muab tag nrho cov ntaub ntawv rau koj, tsis yog tus qauv. Yav dhau los, tus neeg siv khoom ncaj qha txuas cov ntaub ntawv no rau cov ntaub ntawv tshaj tawm, kev tshuaj xyuas tsis tuaj yeem nqa qhov teeb meem.
4. Impurity tswj, uas peb tuaj yeem phim
If you need various impurities of leuprolide for method validation, we can provide single impurity controls with purity >95% thiab cov ntaub ntawv pom zoo. Oxidized impurities, deamidated impurities, peptides ploj yog txhua yam impurities, thiab tshwj xeeb impurities tuaj yeem kho.
Cov neeg R & D ua li cas nrog leuprolide?
Cov txheej txheem dav dav
Nyob rau theem pib ntawm kev tshuaj ntsuam xyuas, ob peb milligrams tau siv los sim cov kev tiv thaiv sib txawv thiab cov resins sib txawv. Thaum nws los txog rau qhov ntsuas ntsuas - nce, peb xav tau kaum ob lossis ntau pua grams txhawm rau khiav qhov ntsuas. Peb tuaj yeem ua raws li cov txheej txheem los ntawm qhov pib mus rau qhov kawg yam tsis tas yuav hloov cov neeg xa khoom hauv nruab nrab ntawm cov txheej txheem, thiab cov ntaub ntawv txheej txheem kuj zoo ib yam.
Pilot scale -up of microsphere formulations
Qhov feem ntau peptide-siv theem ntawm kev ua leuprolide microspheres yog cov txheej txheem tshawb nrhiav thiab teev- nce. Peb batch yog validated, thiab txhua batch tej zaum yuav kaum rau pua pua grams. Peb kilogram- nplai muaj peev xwm tau npaj rau qhov xwm txheej zoo li no. Ib tus neeg siv khoom tau khiav peb qhov kev sim ntawm kev sim nrog peb cov peptide, thiab qhov sib txawv ntawm cov khoom siv me me, thiab tom qab ntawd nws tau ncaj qha xa mus rau cov neeg ua haujlwm batch.
impurity tswj
Thaum tsim cov txheej txheem tshuaj ntsuam xyuas, peb xav tau ntau yam impurities rau kev siv tau. Peb muab ib qho impurity tswj nrog txaus purity thiab tiav cov ntaub ntawv, uas yuav siv tau rau txoj kev loj hlob.
Kev tshawb fawb txog kev ruaj ntseg
Cov khoom sib txawv ntawm peptide xav tau rau lub sijhawm ntev -, nrawm thiab yuam kom degradation. Peb tuaj yeem muab ntau pawg ntawm leuprolide, thiab cov ntaub ntawv tuaj yeem sib piv ntawm cov khoom siv, uas yooj yim rau koj los txiav txim qhov kev hloov pauv.
Ob peb qhov tseeb R & D dab neeg uas
Zaj Dab Neeg 1: Lub tuam txhab tshuaj generic, microsphere pilot scale -nce
Lawv tau sim lwm lub tuam txhab peptide, tab sis thaum lawv tuaj rau qhov kev sim ntsuas, lub tuam txhab tau hais tias lawv tsis tuaj yeem ua qib kilogram. Lawv pom peb, thiab peb tau muab peb cov khoom ntawm leuprolide ncaj qha rau qib kilogram raws li lawv cov kev xav tau, nrog purity saum 99% thiab impurity profiles zoo ib yam li lwm yam peptide hauv kev sim me me. Lawv siv peb pawg no los khiav qhov kev sim, cov ntaub ntawv sib xws tau zoo heev, thiab tom qab ntawd kos npe ncaj qha rau daim ntawv cog lus ntev - cov khoom siv. Tus thawj coj R&D ntawm lwm tus neeg tau hais tias, "Kuv ntshai tshaj plaws ntawm kev hloov cov neeg xa khoom, tab sis koj tuaj yeem ua nws los ntawm qhov me mus rau qhov loj, uas cawm peb ntau yam teeb meem."
Zaj 2: Lub koom haum tshawb fawb hauv tuam txhab tshuaj hauv tsev, kev tshawb fawb impurity
Lawv xav tshaj tawm cov qauv ntawm leuprolide, thiab tsis muaj ob peb yam tseem ceeb ntawm kev tswj tsis huv. Peb tau tsim rau 6 impurities rau lawv, tag nrho cov no yog ntau tshaj 95% ntshiab, nrog NMR thiab MS cov ntaub ntawv lees paub. Lawv siv cov ntaub ntawv ncaj qha rau hauv cov ntaub ntawv, thiab qhov impurity tau dhau los ntawm ib qho mus rau qhov kev ntsuam xyuas, thiab tsis muaj cov khoom ntxiv.
Zaj Dab Neeg 3: Lub tsev muag tshuaj hauv tsev kawm qib siab, qhov ntev - ua kev tshawb fawb txhaj tshuaj
They were studying the release mechanism of leuprolide microspheres and needed peptides of different purity levels for comparison. We provided three kinds of peptides: crude peptide (>80%), standard peptide (>98%) and high purity peptide (>99%), thiab pab lawv ua tiav txoj kev tshawb fawb ntawm kev tso tawm kinetics. Tom qab ntawd, daim ntawv no tau luam tawm nyob rau hauv Phau Tsom Faj Tswj Kev Tso Cai, thiab peb tau hais hauv qhov kev lees paub.
