tcsc0897 5-Iodotubercidin

5-Iodotubercidin is a potent adenosine kinase inhibitor with IC₅₀ of 26 nM.

IC50 & Target: IC50: 26 nM (adenosine kinase)

In Vitro: 5-Iodotubercidin (40 μM) enhances the rate of phosphorylase inactivation and shortens the lag before the activation of glycogen synthase. 5-Iodotubercidin (50 μM) antagonizes the effects of glucagon and vasopressin, but does not affect the basal concentration of free calcium in single hepatocytes^[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^[3]. 5-Iodotubercidin causes a strong decrease in the immunofluorescence levels of P-T3-H3, and depletion of P-T3-H3 is complete at 10 µM 5-5-iodotubercidin^[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].
