Tolazamide (U-17835) is an orally active sulfonylurea agent that inhibits sulfonylurea receptor 1 (SUR1) linked to the inwardly rectifying potassium channel (IC₅₀ = 4.2 µM in HEK293 cells transfected with the human receptor). Tolazamide has anti-diabetic properties. Tolazamide can lower blood glucose in sulfonylurea class. Tolazamide decreases insulin dose while continuing to maintain adequate metabolic control. Tolazamide is able to improve or normalize hyperglycemia and HbA.

Biological Activity

Description

In Vitro

Tolazamide (0.1 nM-1 mM) inhibits Diazoxide (HY-B1140)-evoked responses dose-dependently in SUR1-Kir6.2 transfected HEK293 cells^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Tolazamide (40-400 μg/mL, 2 h) attenuates gluconeogenesis with both doses in control rats and inhibits gluconeogenesis in the liver tissue of diabetic rats with high concentration^[4].
Tolazamide (40-400 μg/mL, 1.5 h) attenuates ketogenesis (nanomoles of palmitate converted per min/mg DNA) from 5.2 to 3.5 and 2.7 with 40 and 400 μg/mL, respectively in the liver tissue of diabetic rats ^[4].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
