Biological Activity

[Description]:

Splitomicin (Splitomycin) is a selective Sir2p inhibitor. Splitomicin inhibits NAD+-dependent HDAC activity of Sir2 protein. Splitomicin induces dose-dependent inhibition of HDAC in the yeast extract with an IC50 of 60 μM[1].

[Target]

Sir2p:60 μM (IC50)

[In Vivo]

Splitomicin (80 mg/kg with an intraperitoneal injection every 24 h for 5 days, in mice) enhances tissue factor (TF) activity in the arterial vessel wall and accelerates carotid artery thrombus formation in a photochemical injury model[2]. Animal Model: C57BL/6 mice aged 12-14 weeks weighing on average 27 g[2] Dosage: 80 mg/kg Administration: Intraperitoneal injection every 24 h for 5 days Result: Increased TF activity in mouse carotid artery as compared with the controls.
