Peptide click chemistry: Precision conjugation rau kev siv biotech siab heev

Click chemistry yog dab tsi?

Click chemistry yog hais txog ib chav kawm ntawm cov tshuaj muaj txiaj ntsig zoo, cov qauv tsim, thiab cov tshuaj tiv thaiv kev ntseeg siab uas tso cai rau kev sib dhos sai ntawm cov tsev me me molecular blocks.introduced los ntawm prof.k.barry sharpless, lub tswv yim no qhia txog cov tshuaj tiv thaiv sai, xaiv, siab -yielding, thiab sib xws nrog aqueous lossis lom ib puag ncig.

Hauv kev tshawb fawb peptide, nyem chemistry tau dhau los ua cov cuab yeej muaj zog rau peptide ligation, cyclization, bioconjugation, fluorescent labeling, thiab nanoparticle deg modification.it enables meej, ruaj khov, thiab bioorthogonal txuas ntawm peptides nrog ntau hom molecules rau biomedical applications.

Core nyem cov tshuaj tiv thaiv hauv peptide chemistry

1.cuaac(copper(i)-catalyzed azide–alkyne cycloaddition)

Feem ntau siv nyem cov tshuaj tiv thaiv hauv peptide chemistry.

Koom nrog kev sib txuas ntawm azide(-n₃) thiab alkyne(-c≡c-) pab pawg los tsim ib lub nplhaib 1,2,3-triazole nyob rau hauv cu(i) catalysis.

Cov txiaj ntsig triazole yog tshuaj lom neeg ruaj khov, hydrolysis-resistant, thiab ua raws li daim ntawv cog lus amide.

2.copper-free click chemistry(spaac)

Tsis txhob cu toxicity nyob rau hauv biological systems.

Siv cov strained alkynes xws li dbco los yog bcn rau spontaneous cov tshuaj tiv thaiv nrog azides.

Zoo tagnrho rau hauv vivo labeling, protein conjugation, thiab nyob - duab cell.

3.on-resin los yog sab- chain click reactions

Clickable amino acids tuaj yeem qhia tau thaum spps(khoom-theem peptide synthesis).

Pab kom intramolecular cyclization, peptide elongation, los yog txuas rau dyes, peg, los yog nanocarriers.

Qhov zoo ntawm nias chemistry rau peptides

Kev siv ntawm click chemistry hauv kev tshawb fawb peptide

Peptide ligation thiab extension-txuas luv peptides los tsim cov saw ntev.

Peptide cyclization- tsim cyclic lossis stapled peptides los txhim kho kev ruaj ntseg thiab bioactivity.

Peptide - tshuaj los yog fluorophore conjugation- rau kev xa khoom thiab kev pom zoo.

Pegylation thiab nanoparticle functionalization- Txhim kho solubility thiab biostability.

Radiolabeling thiab isotope tagging-precise attachment ntawm imaging agents.
