Abstract

Inosine –a naturally occurring purine- was long considered to be an inactive
metabolite of adenosine. However, recently inosine has been shown to be an immuno-modulator and anti-inflammatory agent. The aim of the present study was to
determine whether inosine can affect the development of type 1 diabetes in mice. Type
1 diabetes was induced chemically by multiple low doses of streptozotocin. (MLDS).
Mice were treated with inosine (100 or 200mg/kg/day) and diabetes incidence was
monitored. The effect of inosine on oxidative stress also was determined. The results
showed that inosine reduced the incidence of diabetes in streptozotocin-induced
diabetes and also decreased the oxidative stress. The purine exerts anti-inflammatory
effects in the pancreas, which is its likely mode of action. The use of inosine should be
considered as a potential preventive therapy in humans susceptible to develop Type 1
diabetes.
