3-Deazaadenosine

3-Deazaadenosine has been used as a methylation inhibitor:

• to study the effect of m6A modification on suppressor of cytokine signaling 2 (SOCS2) expression in colon cancer cells
• to study its effects on the expression of influenza A virus (IAV) proteins in human lung epithelial cell line
• to evaluate its effects on the replication of SV40 virus in BSC40 cells

3-Deazaadenosine (DZA), an analog of adenosine, acts as a blocker of S-adenosylhomocysteine (SAH)-hydrolase, a regulator of cellular methyltransferase activity. It has been observed in inhibiting some of the factors involved in atherosclerosis and restenosis. DZA inhibits lymphocyte-mediated tumor cell lysis, macrophage phagocytosis, microfilament disorganization, monocyte, and neutrophil chemotaxis. It also inhibits histamine release by basophils, superoxide anion generation, and macrophage lysosomal secretion. DZA possesses anti-inflammatory, anti-human immunodeficiency virus (HIV) properties and inhibitory effects of cytokine expression that include interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and nuclear factor-κB (NF-κB) transcription activity.

Possesses antiviral activity inhibitor of leukocyte adhesion to TNF-treated endothelial cells.
