Final answer:
5-Azacytidine is a therapeutic drug used in the treatment of leukemia, particularly myelodysplastic syndromes (MDS) that can lead to acute myeloid leukemia (AML). It is an antimetabolite that disrupts DNA synthesis in cancerous cells. The correct option is a.
Step-by-step explanation:
5-Azacytidine has been used as a therapeutic drug in the treatment of leukemia. This drug falls into the category of antimetabolites, which are compounds that interfere with DNA synthesis and cell replication.
In the context of leukemia, 5-Azacytidine functions similarly to other nucleoside analogs, such as cladribine, which are designed to target and disrupt the proliferation of cancerous cells. Therapeutic approaches like 5-Azacytidine are part of a broader spectrum of chemotherapy drugs used to manage and treat various forms of cancer, by inducing apoptosis or programmed cell death in malignant cells.
Chemotherapy treatments can be quite specific to cancer types, and in the case of 5-Azacytidine, it is particularly associated with the management of myelodysplastic syndromes (MDS), which are a group of disorders caused by poorly formed or dysfunctional blood cells, and can progress to acute myeloid leukemia (AML).
Therefore, the correct option is a.
