The antidiabetic drug acarbose suppresses age-related lesions in C57BL/6 mice in an organ dependent manner.

Acarbose (Acb) is an antidiabetic drug used to reduce blood glucose by inhibiting the conversion of complex carbohydrates into simple sugars. It has also shown promise as an anti-aging drug by increasing lifespan in mice but studies have not been reported on the effects of short-term treatment in aging mice. To address this question, 20-month-old C57BL/6 male and female mice were given a standard diet, or a diet supplemented with 1000 ppm Acb for 3 months. After this period, mice were assessed for age-related lesions as readouts for the delay in the progression of aging. Results showed there was a significant decrease in lesions of the heart and kidney in mice treated with Acb suggesting that Acb can suppress cardiac and renal pathology associated with increasing age.
