Azacitidine is a chemotherapeutic agent primarily used in the treatment of myelodysplastic syndromes (MDS), a group of disorders caused by poorly formed or dysfunctional blood cells. It is a pyrimidine nucleoside analog of cytidine and works by incorporating into DNA and RNA, leading to the disruption of nucleic acid synthesis and subsequent cell death. The drug is also used as a treatment option for certain types of leukemia.
