HOW DO DNA ANTINEOPLASTIC METHYLATION INHIBITORS WORK?
Antineoplastic DNA methylation inhibitors are a class of drugs used to treat a group of blood/bone marrow disorders such as myelodysplastic syndromes (group of cancers in which the bone marrow fails to produce healthy blood cells), including chronic myelomonocytic leukemia (a type of cancer that starts in blood-forming cells of the bone marrow).
Myelodysplastic syndromes are a group of hematopoietic neoplasms that give rise to variable cytopenia (reduction in the number of mature blood cells) progressing to secondary acute myeloid leukemia (cancer of the blood and bone marrow), which is invariably fatal if untreated. People with myelodysplastic syndrome may have problems such as infections, anemia (low red blood cell count), and easy bleeding/bruising.
DNA methylation inhibitors belong to a class of medications called “demethylation agents” that work by helping the bone marrow to produce normal blood cells and killing abnormal cells in the bone marrow. They are used to treat myelodysplastic syndrome by inducing DNA hypomethylation and apoptosis (a type of cell death in which a series of molecular steps in a cell lead to its death) of cancerous cells.
DNA methylation inhibitors are administered via intravenous (into a vein) and oral routes.
DNA methylation inhibitors work in the following ways:
- They belong to a class of drugs called "hypomethylation agents" that work by helping the bone marrow produce normal blood cells and killing abnormal cells in the bone marrow.
- They help in slowing down or halting the growth of abnormal blood cells that grow very fast and do not work properly.
- In addition, they induce DNA hypomethylation and apoptosis of cancerous cells.
HOW ARE ANTINEOPLASTIC DNA METHYLATION INHIBITORS USED?
Antineoplastic DNA methylation inhibitors are used to treat conditions such as:
- Myelodysplastic syndromes (group of cancers in which the bone marrow fails to produce healthy blood cells)
- Acute myeloid leukemia (cancer of the blood and bone marrow)
WHAT ARE SIDE EFFECTS OF ANTINEOPLASTIC DNA METHYLATION INHIBITORS?
Some of the common side effects include:
