Polymerizable matrix metalloproteinases’ inhibitors with potential application ...
Laronha, Helena; Carpinteiro, Inês; Portugal, Jaime; Azul, Ana; Polido, Mário; Petrova, Krasimira T.; Salema-Oom, Madalena; Barahona, IsabelCollagen cleavage by matrix metalloproteinase (MMP) is considered a major cause of dental resins long term failure. Most MMP inhibitors display significant toxicity and are unsuitable for dental resins’ applications. Here we report a study of a new class of inhibitors that display the unique property of being co-polymerizable with other vinyl compounds present in commercial dental resins, limiting their release...
Challenges in matrix metalloproteinases inhibition
Laronha, Helena; Carpinteiro, Inês; Portugal, Jaime; Azul, Ana; Polido, Mário; Petrova, Krasimira T.; Salema-Oom, Madalena; Caldeira, JorgeMatrix metalloproteinases are enzymes that degrade the extracellular matrix. They have different substrates but similar structural organization. Matrix metalloproteinases are involved in many physiological and pathological processes and there is a need to develop inhibitors for these enzymes in order to modulate the degradation of the extracellular matrix (ECM). There exist two classes of inhibitors: endogenous...

Structure and function of human matrix metalloproteinases
Laronha, Helena; Caldeira, JorgeThe extracellular matrix (ECM) is a macromolecules network, in which the most abundant molecule is collagen. This protein in triple helical conformation is highly resistant to proteinases degradation, the only enzymes capable of degrading the collagen are matrix metalloproteinases (MMPs). This resistance and maintenance of collagen, and consequently of ECM, is involved in several biological processes and it mus...
