Mechanism of Action of Azacitidine Tablets (Azarest):

Myelodysplastic syndromes (MDS) are a group of heterogeneous hematological disorders characterized by ineffective hematopoiesis, leading to cytopenias and an increased risk of progression to acute myeloid leukemia (AML). Azacitidine, a nucleoside analog, has emerged as a promising therapeutic option for patients with MDS. This article explores the intricate mechanism of action of azacitidine and its impact on the pathophysiology of MDS.

  1. Introduction:

Azacitidine is a cytidine analog that exerts its therapeutic effects through the disruption of DNA methylation, a crucial epigenetic modification involved in the regulation of gene expression. The drug has been approved for the treatment of MDS, including both lower-risk and higher-risk subtypes.

  1. DNA Hypomethylation:

Azacitidine functions as a demethylating agent by incorporating into DNA during cellular replication. Once integrated, azacitidine forms covalent bonds with DNA methyltransferases, irreversibly inhibiting their activity. DNA methyltransferases are enzymes responsible for the addition of methyl groups to cytosine residues, a process critical for the regulation of gene expression.

  1. Reactivation of Tumor Suppressor Genes:

The primary consequence of azacitidine-induced DNA hypomethylation is the reactivation of silenced tumor suppressor genes. In MDS, aberrant hypermethylation of specific genes contributes to the dysregulation of cellular processes, including apoptosis and differentiation. Azacitidine’s demethylating action restores the normal expression patterns of these genes, promoting the restoration of normal hematopoiesis.

  1. Induction of Cell Cycle Arrest and Apoptosis:

Azacitidine disrupts the cell cycle progression of malignant cells by inducing cell cycle arrest and apoptosis. The drug’s interference with DNA methylation leads to the activation of signaling pathways that mediate these processes. This selective cytotoxicity towards abnormal hematopoietic cells is a key factor in its therapeutic efficacy.

  1. Immune Modulation:

Apart from its direct effects on malignant cells, azacitidine also exerts immunomodulatory effects. The drug enhances the immune recognition of cancer cells by upregulating the expression of tumor-associated antigens. Additionally, it promotes the activation of immune effector cells, such as T lymphocytes, further contributing to the elimination of malignant clones.

  1. Clinical Implications:

Azacitidine Tablets has demonstrated clinical efficacy in improving overall survival and delaying disease progression in patients with MDS. Its mechanism of action aligns with the underlying epigenetic alterations observed in MDS, making it a targeted therapeutic option for this patient population.

  1. Conclusion:

In conclusion, azacitidine’s mechanism of action involves the disruption of DNA methylation, leading to the reactivation of tumor suppressor genes, induction of cell cycle arrest and apoptosis, and modulation of the immune response. Understanding these molecular processes is crucial for optimizing the use of azacitidine in the treatment of myelodysplastic syndromes. Ongoing research continues to explore combination therapies and identify predictive biomarkers to enhance the drug’s efficacy and improve patient outcomes.
