Diabetic foot ulcers are a complication of diabetes for which treatment options are limited and not effective, resulting in 73,000 lower-limb amputations in the United States every year. Wound healing is a complex process with a highly orchestrated cascade of events, in which the extracellular matrix (ECM) interacts with growth factors and cells. Matrix metalloproteinases (MMPs) are involved in all wound healing events, in particular MMP-8 and MMP-9, whose physiological functions are to degrade damaged collagen type I and to facilitate keratinocyte migration and re-epithelialization, respectively. MMP substrate redundancy permits another MMP to substitute for MMP-9 during normal wound healing. Under the hypoxic and inflammatory environment of diabetic wounds, increased reactive oxygen species (ROS) and upregulation of MMP-9 results in wounds that are recalcitrant to healing. We have determined that MMP-8 plays a role in the bodyâ¿¿s response to wound healing and that MMP-9 is the pathological consequence of the disease with detrimental effects. Thus, selective inhibition of MMP-9, while leaving MMP-8 activity unaffected, is desirable. ND-336 has such inhibitory profile and is a promising strategy for treatment of diabetic foot ulcers.
