University of Notre Dame researchers have discovered a compound that accelerates diabetic wound healing, which may open the door to new treatment strategies.Non-healing chronic wounds are a major complication of diabetes, which result in more than 70,000 lower-limb amputations in the United States alone each year. The reasons why diabetic wounds are resistant to healing are not fully understood, and there are limited therapeutic agents that could accelerate or facilitate their repair.

A team of researchers from Notre Dame’s Department of Chemistry and Biochemistry, led by Mayland Chang, previously identified two enzymes called matrix metalloproteinases (MMPs), MMP-8 and MMP-9, in the wounds of diabetic mice. They proposed that the former might play a role in the body’s response to wound healing and the latter was the pathological consequence of the disease with detrimental effects. The researchers used the MMP-9 inhibitor referred to as ND-322, which accelerated wound healing in diabetic mice.
