Hordhaca daawooyinka mRNA
Messenger RNA (mRNA) waa taxane nucleotide ah oo soo koobaya borotiinka, cytoplasma dhexdeeda waxa uu awood u leeyahay inuu isticmaalo organelles si uu u muujiyo borotiinka qarsoon. Daawooyinka mRNA waxaa lagu hagaajiyaa kiimikaad iyadoo lagu saleynayo xulashada bartilmaameedyada ama antigens waxayna galaan cytoplasm iyada oo loo marayo nidaam gaar ah oo gaar ah (tusaale, LNP), halkaas oo ay soo saaraan borotiin gaar ah (oo u dhiganta ujeedada naqshadeynta kiimikada), saameyntu waxay ku dhacdaa gudaha gudaha ama ka dib marka lagu sii daayo qaybta ka baxsan unugyada (Jaantus 1). Aragti ahaan mRNA waxaa loo tarjumi karaa borotiin kasta, iyo daawo kasta oo u adeegsata borotiinka sida daawaynta waxaa lagu bedeli karaa daawaynta mRNA.

Xeeladaha daraasaadka farmashiyaha ee dawooyinka mRAN
Marka laga hadlayo daraasadda dawooyinka hore ee dawooyinka mRNA, waxaa loo qaybin karaa saddex qaybood oo daraasado ah oo lagu beegsanayo tallaallada mRNA, daweynta mRNA iyo dawooyinka cusub ee dawooyinka. Marka loo eego tallaalka - tilmaamaha farsamo ee la xidhiidha ee ay soo saareen FDA iyo NMPA, tallaaladu inta badan uma baahna daraasadaha farmashiyaha ee joogtada ah, laakiin qaar ka mid ah tallaalada gaarka ah waa in la darso qaybinta noole. Tallaalka mRNA waxaa iska leh tallaallo gaar ah, kuwaas oo u baahan daraasado qaybinta noole. Iyo daraasadda farmashiyaha ee dawooyinka daweynta mRNA waxay gacan ka geysan kartaa fahamka tirada - Daawooyinka cusub ee dawooyinka, sida lipids-ka cationic ama maaddooyinka kale ee hababka bixinta LNP waa dawooyinka cusub ee dawooyinka, vitro, in vivo iyo daraasaadka isdhexgalka daroogada ayaa loo baahan yahay si waafaqsan "Hagaha Qiimaynta Badbaadada Caafimaad ee Aan ahayn -Daraasada in vitro waxay ka kooban tahay xasiloonida dheef-shiid kiimikaadka iyo aqoonsiga dheef-shiid kiimikaadka ee hababka kala duwan, iyo daraasadda in vivo waxay ka kooban tahay nuugista, qaybinta, dheef-shiid kiimikaadka iyo daraasadaha qashin-saarka ee xayawaanka si loo go'aamiyo in vivo ADME habka loo yaqaan 'excipient'. Is dhexgalka daroogada ee daroogooyinka cusub waa la baaraa iyadoo ku xiran heerka khatarta.
