The matrix metalloproteinase inhibitor marimastat inhibits seizures in a model of kainic acid-induced status epilepticus.

An intra-hippocampus injection of kainic acid serves as a model of status epilepticus and the subsequent development of temporal lobe epilepsy. Matrix metalloproteinase-9 (MMP-9) is an enzyme that controls remodeling of the extracellular milieu under physiological and pathological conditions. In response to brain insult, MMP-9 contributes to pathological synaptic plasticity that may play a role in the progression of an epileptic condition.

Design and synthesis of selective and blood-brain barrier-permeable hydroxamate-based gelatinase inhibitors.

Matrix metalloproteinases (MMPs), a family of zinc-containing endopeptidases involved in the degradation of the extracellular matrix, make a major contribution to the progression of a vast number of diseases, such cancer or epilepsy. Although several MMP inhibitors (MMPi) have been developed to date for the treatment of cancer, they have all failed in clinical trials due to lack of efficacy and, most importantly, the presence of severe side effects. The latter can be explained by their lack of selectivity of these inhibitors.

Matrix metalloproteinase 9 and epileptogenesis - the crucial role of the enzyme and strategies to prevent the disease development.

Epileptogenesis is the process responsible for converting normal brain into an epileptic. It may be triggered by an event such as brain injury or status epilepticus (SE). The main mechanisms responsible include neuroinflammation and blood-brain barrier (BBB) disruption, pathologic neuronal networks' reorganisation and aberrant synaptic plasticity.
