Doksorubicin (adriamicin, hidroksidaunorubicin) je lek koji se koristi hemoterapiji. On je antraciklinski antibiotik, blisko srodan asa prirodnim proizvodom daunomicinom, i poput svih antraciklina, on deluje putem interkalacije DNK.

Doksorubicin se često koristi za tretiranje širokog opsega kancera, koji obuhvata hematološke malignosti, nih tipova karcinoma, i sarkome mekog tkiva.

Doksorubicinovo najozbiljnije nepoželjno dejstvo je potencijalno smrtonosno oštećenje srca.

Ovaj lek se dozira intravenozno, u obliku hidrohloridne soli. Neka od njegovih prodajnih imena su Adriamycin PFS, Adriamycin RDF, i Rubex.^[7] Doksorubicin je fotosenzitivan, te su kontajneri često oblošeni aluminijumskom folijom i/ili voštanim papirom.

Doksorubicin je dostupan u lipozomskoj formulaciji kao Doxil, Caelyx i Myocet.

Ovaj molekul je originalno izolovan tokom 1950-tih iz bakterija u uzorku zemljišta iz Italije.

Mehanizam dejstva

Doksorubicin formira interakcije sa DNK putem interkalacije čime se inhibira makromolekulska biosinteza.^[9]^[10] On inhibira rad enzima topoizomeraza II, koji opušta supernamotaje tokom transkripcije DNK. Doksorubicin stabilizuje kompleks topoizomerase II nakon prekidanja DNK lanca radi replikacije, čime se sprečava otpuštanje dvostrukog heliksa i time se zaustavlja proces replikacije.

Planarna aromatična hromoforna porcija molekula se interkalira između dva bazna para DNK molekula, dok se šestočlani šećer smešta u mali žleb i formira interakcije sa bočnim baznim parovima u neposrednom susedstvu mesta interlalacije. Ovaj mod vezivanja je uočen u nekoliko kristalnih struktura.^[8]^[11]
