Diallyl disulfide regulates purine metabolism and their metabolites in diabetes mellitus

Abstract

Objectives: The garlic and its principle sulfur compound, diallyl disulfide (DADS), have been claimed to have hypoglycemic activity and are helpful in achieving glycemic control in diabetes mellitus. The exact uric acid mechanism about the DADS controls on glucose level in diabetes mellitus is not clearly established though it is known that DADS does influence insulin action probably by improving insulin half-life. A study was undertaken to examine the role of DADS on purine metabolism and their metabolites in the diabetic condition and the probable connection of uric acid, xanthine oxidase and adenosine deaminase (ADA) enzymes in rat model. Materials and Methods: The induction of diabetes was done by alloxan and diabetic rats were treated with DADS for 30 days and compared with the standard hypoglycemic drug metformin. Purine metabolites alteration was measured by the activities of ADA, xanthine oxidase, and uric acid in the diabetes induced rats. Results: DADS which exhibits its strong action on glucose utilization in the liver tissues by regulating the purine metabolites in diabetic condition showing favorable changes in the levels of xanthine oxidase, ADA, and uric acid levels. Conclusion: This establish the possible effect of DADS on purine metabolites in alloxan diabetic liver tissues and to associate this action of DADS with metformin which is a common drug used for treating type-2 diabetes mellitus. DADS can be used as a therapeutic drug for glycemic control in diabetes mellitus.
