Nucleosides, zvivharo zvekuvaka zve nucleic acids (DNA neRNA), inoita basa rakakosha mune zvese zvipenyu. Nekugadzirisa mamorekuru aya, masayendisiti akavhura huwandu hwakawanda hwezvinogona kushandiswa mukutsvagisa nemushonga. Muchikamu chino, tichaongorora mamwe akakosha maapplication eyakagadziridzwa nucleosides.
Basa reModified Nucleosides
Manucleosides akagadziridzwa anogadzirwa nekuchinja maumbirwo emasikirwo nucleosides, akadai seadenosine, guanosine, cytidine, uye uridine. Aya magadzirirwo anogona kusanganisira shanduko kune hwaro, shuga, kana zvese zviri zviviri. Iyo yakashandurwa chimiro inogona kupa zvivakwa zvitsva kune yakagadziridzwa nucleoside, ichiita kuti ive yakakodzera kune akasiyana maapplication.
Key Applications
Kuwanikwa kwezvinodhaka:
Anticancer agents: Manucleosides akagadziridzwa akashandiswa kugadzira mhando yemishonga inorwisa cancer. Semuenzaniso, anogona kugadzirwa kuti avhare DNA synthesis kana kunanga chaiwo maseru egomarara.
Antiviral agents: Nucleosides dzakagadziridzwa dzinoshandiswa kugadzira mishonga inorwisa mavhairasi inogona kurambidza kudzokororwa kwehutachiwana. Muenzaniso unonyanya kuzivikanwa ndeyekushandiswa kweakagadziridzwa nucleosides muCOVID-19 mRNA vaccine.
Antibacterial agents: Nucleosides dzakagadziridzwa dzakaratidzawo vimbiso mukugadzirwa kwemishonga mitsva.
Genetic Engineering:
MRNA vaccines: Kugadziridzwa nucleosides zvakakosha zvikamu zveMRNA vaccine, sezvo inogona kuwedzera kugadzikana uye immunogenicity yemRNA.
Antisense oligonucleotides: Aya mamorekuru, akagadzirirwa kusunga kune chaiwo mRNA sequences, anogona kuchinjwa kuti avandudze kugadzikana kwavo uye kujeka.
Gene therapy: Modified nucleosides inogona kushandiswa kugadzira oligonucleotides yakagadziridzwa yemajini therapy maapplication, sekugadzirisa kukanganiswa kwemajini.
Zvishandiso Zvekutsvaga:
Nucleic acid probes: Yakagadziridzwa nucleosides inogona kuiswa mumaprobes anoshandiswa muhunyanzvi hwakaita sefluorescence in situ hybridization (FISH) uye microarray analysis.
Aptamers: Aya ma-single-stranded nucleic acids anogona kugadziridzwa kuti asunge kune zvakanangwa, senge mapuroteni kana mamorekuru madiki, uye ane maapplication mudiagnostics uye therapeutics.
Benefits of Modified Nucleosides
Kuvandudza kugadzikana: Kugadziriswa nucleosides kunogona kuwedzera kugadzikana kwe nucleic acids, zvichiita kuti irambe ichidzivirira kuparara nema enzymes.
Kuwedzera hunhu: Shanduko dzinogona kuvandudza hunhu hwenyucleic acid kupindirana, zvichiita kuti kutarisisa kwakaringana kweakananga biological mamorekuru.
Kuwedzeredzwa kweserura kutorwa: Yakagadziridzwa nucleosides inogona kugadzirwa kuti ivandudze kutora kwavo cellular, kuwedzera kushanda kwavo mukurapa kwekushandisa.
Mhedziso
Manucleosides akagadziridzwa akachinja zvinhu zvakasiyana-siyana, kubva pakuwanikwa kwezvinodhaka kusvika kumajini enjiniya. Kuita kwavo kwakasiyana-siyana uye kugona kugadzirwa kune chaiwo maapplication anovaita maturusi akakosha kune vaongorori nevarapi. Sezvo kunzwisisa kwedu kwe nucleic acid chemistry kuri kuramba kuchikura, tinogona kutarisira kuona mamwe mashandisirwo eakagadziridzwa nucleosides mune ramangwana.
