Gemcitabin je nukleozidni analog koji se koristi kao sredstvo za hemoterapiju. U prodaji je pod imenom Gemzar. Gemcitabin je organsko jedinjenje, koje sadrži 9 atoma ugljenika i ima molekulsku masu od 263,198 Da.^[6]^[7]

Farmakologija

Gemcitabin je nukleozidni analog u kome su atomi vodonika na 2' ugljeniku deoksicitidina zamenjeni atomima fluora.

Poput fluorouracila i drugih analoga pirimidina, trifosfatni analog gemcitabina zamenjuje jedan od gradivnih blokova nukleinskih kiselina, u ovom slučaju citidin, tokom replikacije DNK. Proces se bazira na rastu tumora, pošto se samo jedan dodatni nukleozid može vezati za "neispravni" nukleozid, što dovodi do apoptoze.

Dodatna meta gemcitabina je enzim ribonukleotidna reduktaza (RNR). Difosfatni analog se vezuje za RNR aktivno mesto i ireverzibilno deaktivira enzim. Nakon inhibicije RNR, ćelija ne može da proizvede deoksiribonukleotidee koji su neophodni za replikaciju i popravku DNK, i time se indukuje apoptoza.^[8]
