New in Vivo Compatible Matrix Metalloproteinase (MMP)-2 and MMP-9 Inhibitors
2018
Matrix metalloproteinases (MMPs) are emerging as pivotal fine-
tunersof cell function in tissue homeostasis and in various pathologies, in particular inflammation. In vivo monitoring of the activity of specific MMPs, therefore, provides high potential for assessing disease progression and tissue function, and manipulation of MMP activity in tissues and whole organisms may further provide a mode of controlling pathological processes. We describe here the synthesis of novel fluorinated and nonfluorinated analogues of a secondary sulfonamide-based lead structure, compound 2, and test their efficacy as in vivo inhibitors and tracers of the
gelatinases, MMP-2 and MMP-9. Using a murine neuroinflammatory model, we show that compound 2 is a highly effective in vivo inhibitor of both MMP-2 and MMP-9 activity with little or no adverse effects even after long-term daily oral administration. A fluorescein-labeled derivative compound 17 shows direct binding to activated
gelatinasessurrounding inflammatory cuffs in th...
