Acting on a broad spectrum of extracellular, intracellular, and membrane-associated substrates, the matrix metalloproteinases (MMPs) are critical to the biological processes of organisms; when aberrantly expressed, many pathological conditions may be born or exacerbated. The prospect of MMP inhibition for therapeutic benefit in cancer, cardiovascular disease, and
stroke
is reviewed here. MMP inhibitor (MMPI) development constitutes an important branch of research in both academic and industrial settings and advances our knowledge on the structure-function relationship of MMPs. Targeting MMPs in disease treatment is complicated by the fact that MMPs are indispensable for normal development and physiology and by their multi-functionality, possible functional redundancy or contradiction, and context-dependent expression and activity. This complexity was revealed by previous efforts to inhibit MMP activity in the treatment of cancer patients that yielded unsatisfactory results. This review focuses on MMPI development since the late 90s, in terms of natural products and their derivatives, and synthetic compounds of low molecular mass incorporating specific zinc-binding groups (ZBGs). A few polyphenols and flavonoids that exhibit MMPI activities may have chemopreventive and neuro- and cardiovascular-protective effects. A new generation of potent and selective MMPIs with novel ZBGs and inhibition mechanisms have been designed, synthesized, and tested. Although only one collagenase inhibitor (
Periostat
, doxycycline hyclate) has been approved by the Food and Drug Administration as a drug for the treatment of periodontal disease, new hope is emerging in the form of natural and synthetic MMPIs for the prevention and treatment of
stroke
, cardiovascular disease, cancer, and other medical conditions.

Extracellular matrix (ECM) molecules, their receptors at the cell surface, and cell adhesion molecules (CAMs) involved in cell-cell or cell-ECM interactions are implicated in processes related to major diseases of the central nervous system including Alzheimer's disease (AD), epilepsy, schizophrenia, addiction, multiple sclerosis, Parkinson's disease, and cancer. There are multiple strategies for targeting the ECM molecules and their metabolizing enzymes and receptors with antibodies, peptides, glycosaminoglycans, and other natural and synthetic compounds. ECM-targeting treatments include chondroitinase ABC, heparin/heparan sulfate-mimicking oligosaccharides, ECM cross-linking antibodies, and drugs stimulating expression of ECM molecules. The amount or activity of ECM-degrading enzymes like matrix metalloproteinases can be modulated indirectly via the regulation of endogenous inhibitors like TIMPs and RECK or at the transcriptional and translational levels using, e.g., histone deacetylase inhibitors, synthetic inhibitors like
Periostat
, microRNA-interfering drugs like AC1MMYR2, and natural compounds like flavonoids, epigallocatechin-3-gallate, anacardic acid, and erythropoietin. Among drugs targeting the major ECM receptors, integrins, are the anticancer peptide cilengitide and anti-integrin antibodies, which have a potential for treatment of
stroke
, multiple sclerosis, and AD. The latter can be also potentially treated with modulators of CAMs, such as peptide mimetics derived from L1-CAM and NCAM1.
