Application

Splitomicin was used to inhibit SIRT1 in human aortic endothelial cells and sirtuins in human breast cancer cells. Mouse leukaemic monocyte macrophage cell line was treated with Splitomicin prior to cholesterol efflux studies.

Actions biochimiques/physiologiques

Splitomicin, a derivative of β-naphthol is an inhibitor of Silent Information Regulator 2 (SIR2). It inhibits the NAD+-dependent deacetylase activity of Sir2 in vitro. It increases the levels of cyclic AMP by inhibiting the activity of cyclic AMP phosphodiesterase, interferes with mobilization of intracellular Ca+2 and ATP release. This results in inhibition of platelet aggregation that is effective in cardiovascular and cerebrovascular diseases.
Sir2p (silent information regulator) and HDAC inhibitor.

Annual review of biochemistry, 73, 417-435 (2004-06-11)
The yeast SIR protein complex has been implicated in transcription silencing and suppression of recombination. The Sir complex represses transcription at telomeres, mating-type loci, and ribosomal DNA. Unlike SIR3 and SIR4, the SIR2 gene is highly conserved in organisms ranging

Splitomicin is derived from beta-naphthol and is an inhibitor of Silent Information Regulator 2 (SIR2). Its naphthoic moiety might be responsible for its inhibitory effects on platelets. The major goal of our study was to examine possible mechanisms of action

The precise mechanism for reduced thrombosis in prekallikrein null mice (Klkb1(-/-)) is unknown. Klkb1(-/-) mice have delayed carotid artery occlusion times on the rose bengal and ferric chloride thrombosis models. Klkb1(-/-) plasmas have long-activated partial thromboplastin times and defective contact

In unstressed cells, the p53 tumor suppressor is highly unstable. DNA damage and other forms of cellular stress rapidly stabilize and activate p53. This process is regulated by a complex array of post-translational modifications that are dynamically deposited onto p53.

Epithelial-to-mesenchymal transition (EMT) in nasal epithelial cells is involved with tissue remodeling of nasal polyps. The present study investigated the molecular mechanisms through which miR‑155‑5p regulated EMT in chronic rhinosinusitis (CRS). Patients were divided into the following groups: CRSsNP, CRS
