ABSTRACT
Aim To investigate the hypoglycemic effect of alismoxide. Methods Type 2 diabetes mellitus (DM) mouse model induced by combined administration of streptozotocin and nicotinamide was adopted. Three weeks later, blood glucose of blank control group and type 2 diabetic mouse model group was measured on day 21 , and oral glucose tolerance test(OGTT) was carried out on day 2 2 , respectively. After type 2 diabetic mouse model was successfully established, rosiglitazorie was chosen as positive drug. Oral administration of rosiglitazone at dose of 10 mgk g-1 daily was performed for three weeks in positive group. Oral administration of alismoxide at dose of 5 , 10 and 20 mg kg"1 daily for three weeks was carried out in alismoxide different dose group, respectively. Furthermore, influence of alismoxide on differentiation was investigated in 3T3-L1 pre-adipocytes, and Oil red 0 staining was adopted. Results Not only blood glucose was decreased by alismoxide in type 2 DM mice, but also hypoglycemic trend was exhibited during OGTT. Furthermore, at concentration of 0. 5 and 1 fimol L " 1 , alismoxide promoted 3T3-L1 pre-adipocyte differentiation. Conclusions It suggests that alismoxide might possess hypoglycemic property and accelerate pre-adipocyte differentiation; however, the mechanism involved needs further study.
