5-IODOTUBERCIDIN

Chemical Properties

Tan Solid

Uses

A potent and competitive inhibitor of ERK2, PKA, and ADK.

Uses

5-Iodotubercidin has been used for the inhibition of retinoblastoma cells, astroglial cultures and for the inhibition of adenosine kinase in human umbilical vein endothelial cells (HUVECs).

Uses

An analogue of the antibiotic tubercidin, a pyrrolo[2,3-d]pyrimidine nucleoside antibiotic. A potent inhibitor of adenosine kinase from rat or guinea pig brain. Inhibits uptake of 3H-adenosine into brain slices.

General Description

solubility: 10 mg/mL in DMSO

Biological Activity

Potent adenosine kinase inhibitor (IC 50 = 26 nM) and nucleoside transporter inhibitor (IC 50 values are 7, 15 and < 25 nM for inhibition of [ 3 H]-uridine, [ 3 H]-formycin B and [ 3 H]-adenosine uptake respectively). Strongly stimulates glycogen synthesis in hepatocytes via activation of glycogen synthase. Also inhibits CK1, insulin receptor tyrosine kinase, phosphorylase kinase, PKA, CK2 and PKC (IC 50 values are 0.4, 3.5, 5-10, 5-10, 10.9 and 27.7 μ M respectively).

Biochem/physiol Actions

Potent inhibitor of adenosine uptake into brain, and of adenosine kinase and subsequent metabolism of adenine nucleotides. In cultured rat hepatocytes, 5-iodotubercidin inhibits both acetyl-CoA carboxylase and de novo synthesis of fatty acids and cholesterol.

storage

Store at -20°C
