Ntu 1: Cov qauv thiab kev faib tawm

Dermorphin yog luv luv -chain bioactive peptide nrog cov amino acid sib lawv liag ntawm Tyr-D-Ala-Ph-Gly-Tyr-Pro-Ser-NH2.

Ib qho ntawm nws cov yam ntxwv tseem ceeb yog qhov muaj D-configuration amino acid (D-Ala), ib qho qauv uas tsis tshua muaj nyob rau hauv ntuj peptides tab sis tseem ceeb heev rau nws cov kev ua si lom neeg thiab kev ruaj ntseg enzymatic. Vim li no, Dermorphin tsis yog sai sai degraded los ntawm cov pa proteases nyob rau hauv vivo, muaj kev ruaj ntseg siab.

Los ntawm kev faib cov khoom muag, Dermorphin raw cov ntaub ntawv feem ntau tuaj yeem muab faib ua pawg hauv qab no:

Ua ntej, siab -kev tshawb fawb purity-qib Dermorphin, nrog purity feem ntau siab tshaj 98%, haum rau kev sim ntawm tes, receptor binding thwmsim, thiab hauv vitro functional kev tshawb fawb.

Thib ob, kev tswj hwm tus qauv-qib Dermorphin, siv rau kev txheeb xyuas txoj kev tsim, tswj kev ua haujlwm receptor, thiab kev ntsuas tshuaj pharmacodynamic.

Thib peb, kev cai - hloov kho Dermorphin, xws li hloov kho los yog isotopically sau npe versions, feem ntau yog siv rau kev tshawb fawb txog kev siv tshuab thiab kev sim ntsuas.

Ntu 2: Physicochemical Properties

Dermorphin muaj qhov hnyav molecular ntawm kwv yees li 803.9 Da, uas yog nyob rau qib qis molecular peptide. Nws cov khoom physicochemical muaj cov yam ntxwv ntawm peptide, thaum tseem muaj qee qhov sib txawv vim nws qhov sib txawv.

Lub cev, Dermorphin feem ntau yog amorphous lossis microcrystalline hmoov. Nws yog yooj yim soluble nyob rau hauv dej, dilute acidic tsis daws teeb meem, thiab ib co polar organic solvents, xws li methanol thiab acetonitrile aqueous daws. Nws muaj kev ruaj ntseg zoo nyob rau hauv nruab nrab los yog tsis muaj zog acidic ib puag ncig, tab sis tej zaum yuav degrade nyob rau hauv siab kub, muaj zog alkaline tej yam kev mob, los yog ntev raug rau lub teeb.

Los ntawm kev pom kev ruaj ntseg tshuaj, Dermorphin nthuav tawm qee qhov kev tiv thaiv rau proteases, tshwj xeeb tshaj yog piv rau peptides uas muaj tag nrho L-amino acids, ua rau lub sijhawm ntev dua hauv vitro stability. Qhov no yog ib qho ntawm cov laj thawj tseem ceeb rau nws nquag siv hauv kev tshawb fawb receptor.

Ntu 3: Cov tsos mob thiab kev hnov lus zoo

Siab - zoo Dermorphin hmoov feem ntau yog dawb los yog tawm -dawb, qee zaum nrog lub teeb daj daj heev. Cov xim no feem ntau muaj feem xyuam rau cov txheej txheem synthesis, purification theem, thiab lyophilization tej yam kev mob. Cov khoom tsim nyog yuav tsum tsis pub pom impurities, tsis muaj ntxhiab, thiab muaj cov hmoov zoo, zoo ib yam.

Yog hais tias cov hmoov yog pom daj, greyish, los yog pom clumping, nws feem ntau qhia tau hais tias tsis txaus purification, noo noo nqus, los yog tsis tsim nyog cia tej yam kev mob. High -Dermorphin zoo muaj cov dej ntws zoo hauv lub xeev qhuav, haum rau kev ntsuas qhov tseeb thiab kev sim ua haujlwm.

Ntu 4: Qhov Tseem Ceeb Zoo thiab Nta

Dermorphin qhov txiaj ntsig zoo tshaj plaws nyob rau hauv nws cov kev xaiv siab thiab muaj kev sib raug zoo rau μ-opioid receptors. Hauv kev sim receptor binding thwmsim, nws cov haujlwm yog siab dua li ntau cov tshuaj opioid peptides, ua rau nws yog ib qho cuab yeej zoo tshaj plaws rau kev kawm txog txoj hauv kev kho mob thiab opioid receptor signaling.

Qhov thib ob qhov zoo dua yog nws cov qauv kev ruaj ntseg zoo. Kev taw qhia ntawm D-amino acids txo qis kev pheej hmoo ntawm kev degradation sai los ntawm proteases, ua rau lub sijhawm ntev ntawm kev ua haujlwm hauv vitro kev sim thiab qee yam hauv vivo qauv.

Qhov thib peb qhov zoo dua yog nws qhov zoo -txhais qauv molecular thiab siab rov tsim dua tshiab. Cov khoom siv niaj hnub no-theem synthesis thev naus laus zis tso cai rau kev ruaj khov ntawm Dermorphin raw cov ntaub ntawv nrog cov khoom zoo-rau-batch sib xws, ua kom yooj yim rau kev sib piv cov ntaub ntawv thiab cov txiaj ntsig rov ua dua nyob rau hauv ntev- cov haujlwm tshawb fawb.

Part 5: Synthesis Process thiab Purification

Niaj hnub no Dermorphin feem ntau yog npaj los ntawm cov khoom -theem peptide synthesis. Cov txheej txheem no siv cov resin ua cov cab kuj txuas ntxiv mus txuas cov amino acid residues, qhia D-configured amino acids nyob rau hauv cov kauj ruam tseem ceeb. Tom qab synthesis, cov khoom tseem ceeb yog tau los ntawm cov kauj ruam xws li cleavage, deprotection, thiab crude khoom los nag.

Tom qab ntawd, thim rov qab-theem siab-kev ua haujlwm ua kua chromatography (RP-HPLC) yog siv rau kev ua kom huv huv kom tshem tawm cov peptides luv luv, tsis muaj qhov tshwm sim, thiab cov khoom lag luam. Thaum kawg, ruaj khov, siab - purity hmoov yog tau los ntawm lyophilization. Tag nrho cov txheej txheem yuav tsum muaj kev tswj xyuas nruj heev ntawm cov tshuaj tiv thaiv thiab cov kev ua kom huv huv, ua rau nws yog ib qho tseem ceeb hauv kev paub qhov txawv ntawm cov khoom zoo tib yam los ntawm qib siab - cov ntaub ntawv zoo.
