MMP-12 is a member of matrix metalloproteinases (MMPs) family involved in pathogenesis of some inflammatory based diseases. Design of selective matrix MMPs inhibitors is still challenging because of binding pocket similarities among MMPs family. We tried to generate a HQSAR (hologram quantitative structure activity relationship) model for a series of MMP-12 inhibitors. Compounds in the series o...

BACKGROUND Overexpression of matrix-metalloproteinases (MMPs) has been shown to lead to tissue damage in equine recurrent airway obstruction (RAO), as a misbalance with their natural inhibitors, the tissue inhibitors of metalloproteinases (TIMPs), occurs. This favors irreversible pulmonary fibrosis formation. Increased levels of MMPs, TIMPs or altered ratios between them can be used as biomarke...

Matrix metalloproteases (MMPs) are important enzymes required in extracellular matrix (ECM) degradation for creating the cellular environments to maintain numerous physiological processes ranging from development to wound repair. However, MMP activity is strictly controlled and imbalance in the levels of MMP family members and its inhibitors has been implicated as an etiological factor in sever...

Pleomorphic adenoma (PA) is the most common neoplasm of salivary glands and consists epithelial mesenchymal components. Although a benign lesion, it harbors potential for recurrence malignant transformation. Also, due to its histological diversity unpredictive behavior PA can represent both diagnostic therapeutic challenge. Matrix metalloproteinases (MMPs) are well known modifiers extracellular...

Matrix metalloproteinases (MMP) are a group of proteinases that have normal physiologic roles degrading and remodeling the extracellular matrix. They also have multiple roles in different stages of tumor progression. Elevated levels of MMPs have been observed in many tumors; these increases have a strong association with the invasive phenotype. MMP-2 and MMP-9 are particularly involved in cance...

Synthetic inhibitors of matrix metalloproteinases (MMPs), designed previously, as well as tissue inhibitors of metalloproteinases (TIMPs) lack enzyme selectivity, which has been a major obstacle for developing inhibitors into safe and effective MMP-targeted drugs. Here we designed a fusion protein named APP-IP-TIMP-2, in which the ten amino acid residue sequence of APP-derived MMP-2 selective i...

The zinc-dependent gelatinases belong to the family of matrix metalloproteinases (MMPs), enzymes that have been shown to play a key role in angiogenesis and tumor metastasis. These enzymes are capable of hydrolyzing extracellular matrix (ECM) components under physiological conditions. Specific and selective inhibitors aimed at blocking their activity are highly sought for use as potential thera...

Cerebral Ischemia, Matrix Metalloproteinases, and TNF: MMP Inhibitors May Act Not Exclusively by Reducing MMP Activity To the Editor: We thank Drs Pfefferkorn and Rosenberg for their enlightening paper1 on matrix metalloproteinases (MMPs) after ischemic stroke. MMPs are attributed an important role in the pathophysiology of cerebral ischemia. The gelatinases MMP-2 and MMP-9 are of particular in...

Since its original identification as a leukocyte gelatinase/type V collagenase and tumour type IV collagenase, gelatinase B/matrix metalloproteinase (MMP)-9 is now recognised as playing a central role in many aspects of tumour progression. In this review, we relate current concepts concerning the many ways in which gelatinase B/MMP-9 influences tumour biology. Following a brief outline of the g...
