Pyrimidine dicarboxamides are highly selective MMP-13 inhibitors. In the S1’ pocket of MMP-13 is an S1’ side pocket that is unique to the matrix metalloproteiase. Pyrimidine dicarboxamides bind to this side pocket, which increases the selectivity. The role of MMP-13 is cleaving fibrillar collagen at neutral pH and higher mRNA levels of MMP ...
[5] [6] It is a member of the matrix metalloproteinase (MMP) family. Like most MMPs, it is secreted as an inactive pro-form. [7] MMP-13 has a predicted molecular weight around 54 kDa. [8] It is activated once the pro-domain is cleaved, leaving an active enzyme composed of the catalytic domain and the hemopexin-like domain . Although the actual ...
A number of rationally designed MMP inhibitors have shown some promise in the treatment of pathologies that MMPs are suspected to be involved in (see above). However, most of these, such as marimastat (BB-2516), a broad-spectrum MMP inhibitor, and cipemastat (Ro 32-3555), an MMP-1 selective inhibitor, have performed poorly in clinical trials .
Various research groups have already suggested many strategies for improving the effectiveness of MMP inhibitors in cancer treatment. First, highly specific MMP inhibitors could be used to target the functions of specific MMPs, which should allow doctors to increase the treatment dosage while minimizing adverse side effects. MMP inhibitors ...
Overall, all MMPs are inhibited by TIMPs once they are activated, but the gelatinases (MMP-2 and MMP-9) can form complexes with TIMPs when the enzymes are in their latent form. The complex of latent MMP-2 (pro-MMP-2)with TIMP-2 serves to facilitate the activation of pro-MMP-2 at the cell surface by MT1-MMP , a membrane-anchored MMP.
Other serious side effects include an increased risk of cancer, progressive multifocal leukoencephalopathy, anemia, and gastrointestinal bleeding. [14] Use during pregnancy may harm the baby. [ 14 ] It works by blocking inosine monophosphate dehydrogenase (IMPDH), which is needed by lymphocytes to make guanosine .
[9] [6] Other side effects may include feeling lightheaded with standing due to changes in blood pressure, and angioedema. [9] Tamsulosin is an alpha blocker and works by relaxing muscles in the prostate. [10] Specifically it is an α 1-adrenergic receptor blocker. [6] Tamsulosin was approved for medical use in the United States in 1997. [6]
Dorzolamide, developed by Merck, was the first medication in human therapy (market introduction 1995) that resulted from structure-based drug design. It was developed to circumvent the systemic side effects of acetazolamide which has to be taken orally. [8]
