Description

5-Iodotubercidin (NSC 113939), an ATP mimetic, is a potent adenosine kinase inhibitor with an IC50 of 26 nM. 5-Iodotubercidin (NSC 113939) initiates glycogen synthesis in isolated hepatocytes by causing inactivation of phosphorylase and activation of glycogen synthase. 5-Iodotubercidin (NSC 113939) also inhibits CK1, insulin receptor tyrosine kinase, phosphorylase kinase, PKA, CK2, PKC and Haspin[1][2][3].

IC50 & Target

IC50: 26 nM (adenosine kinase)

In Vitro

5-Iodotubercidin (NSC 113939) inhibits CK1, insulin receptor tyrosine kinase, phosphorylase kinase, PKA, CK2 and PKC, and the IC50 values are 0.4, 3.5, 5-10, 5-10, 10.9 and 27.7 μM respectively[1].
5-Iodotubercidin (20 μM) causes an important decrease in ATP concentration, and a concomitant smaller increase in AMP concentration. 5-Iodotubercidin decreases the activity of ACC and the rates of synthesis of fatty acids and cholesterol. In line with the iodotubercidin-mediated inhibition of ACC, 5-iodotubercidin induces a marked decrease in the intracellular concentration of malonyl-CoA[4].

In Vivo

5-Iodotubercidin (1 mL/kg, i.p.) is in agreement with activity observed against bicuculline-induced seizures following local administration of the AKI into the prepiriform cortex[2].

Kinase Assay
[2]

AK activity is measured in a radiochemical assay. The final reaction volume is 100 µL and contained 70 mM Tris-maleate (pH 7.0), 0.1% (w/v) bovine serum albumin, 1.0 mM MgCl2, 1.0 mM ATP, 1.0 µM [U-14C]adenosine (400-600 mCi/mmol) and various inhibitor concentrations. Inhibitors are prepared as 10 mM stock solutions in DMSO. The final DMSO concentration in the assay is 5% (v/v). Eleven different concentration of the test solutions ranging from 0.001 to 10.0 µM are utilized to determine a dose response curve of the inhibition of the enzyme. Reactions are started by adding the appropriate amount of purified human recombinant AK and incubated for 20 min at 37°C. The reactions are terminated by addition of the potent AKI GP3269. A 30-µL aliquot of each reaction is spotted on DEAE cellulose filter paper (cut in squares of appr 1×1 cm) and air-dried for 30 min. The dry filters are then washed for 3 min in deionized water to remove residual [U-14C]adenosine, rinsed with ethanol and dried at 90°C for 20 min. The filter papers are counted in 5.5 mL of Ready Safe liquid scintillation cocktail using a Beckman LS3801 scintillation counter. Control AK activity is determined from the amount of [14C]AMP formed in the presence of 5% DMSO. The concentration of inhibitor required to inhibit 50% of the AK activity (IC50) is determined graphically from plots of inhibitor concentration versus percent (%) control enzyme activity.

Cell Assay
[4]

HeLa cells are grown in DME supplemented with 10% fetal bovine serum (FBS) and 2 mM l-glutamine. Nocodazole is used at a concentration of 3.3 µM unless differently specified. Thymidine (2.5 mM) is used in the asssay. For transfection, FuGENE 6 Transfection Agent is used at a 3:1 ratio with plasmid DNA. Cells are analyzed 24-48 h after transfection.

Animal Administration
[2]

Male SA rats (100-150 g) are maintained on a 12:12 light:dark cycle in temperaturecontrolled facilities with free access to food and water. One hour prior to seizure testing, the animals are injected intraperitoneally (1 mL/kg) with DMSO vehicle or with test compound dissolved in DMSO. At the time of the test, an electrolyte solution (2% lidocaine in 0.9% sodium chloride) is applied to the eyes. Maximal electroshock seizures are induced by administering a 60-Hz current of 150 mA for 0.2 s via corneal electrodes, using a Wahlquist Model H stimulator. The endpoint measured is suppression of hindlimb tonic extension (HTE) and expressed as percentage of animals in which the response is inhibited. At this supramaximal stimulation level, virtually 100% of control (vehicle-treated) animals show HTE. ED50 values are calculated from a dose-response curve using probit analysis. The N for the screening doses is 6-8; doseresponse determinations are conducted with at least 5 animals/dose.
