Matrix metalloproteinases (MMPs), also known as matrix metallopeptidases or matrixins, are metalloproteinases that are calcium-dependent zinc-containing endopeptidases; other family members are adamalysins, serralysins, and astacins. The MMPs belong to a larger family of proteases known as the metzincin superfamily.
Protease inhibitors (PIs) are medications that act by interfering with enzymes that cleave proteins. Some of the most well known are antiviral drugs widely used to treat HIV/AIDS, hepatitis C and COVID-19. These protease inhibitors prevent viral replication by selectively binding to viral proteases and blocking proteolytic cleavage of protein precursors that are necessary for the production of infectious viral particles.
Endostatin is a naturally occurring, 20-kDa C-terminal fragment derived from type XVIII collagen. It is reported to serve as an anti-angiogenic agent, similar to angiostatin and thrombospondin.
British Biotech was a British-based biotechnology company founded as British Biotechnology Limited in 1986 by former G D Searle managers Keith McCullagh and Brian Richards. It was the first British biotech company to be publicly listed when it was floated on 1 July 1992.
Dz13 is an experimental treatment developed by scientists at the University of New South Wales. The drug aims to combat a range of illnesses, including skin cancer, restenosis, arthritis and macular degeneration. Trials of Dz13 were suspended in 2013.
Marimastat was a proposed antineoplastic drug developed by British Biotech. It acted as a broad-spectrum matrix metalloproteinase inhibitor.
Cediranib is a potent inhibitor of vascular endothelial growth factor (VEGF) receptor tyrosine kinases.
Sanford Burnham Prebys is a 501(c)(3) non-profit medical research institute focused on basic and translational research, with major research programs in cancer, neurodegeneration, diabetes, infectious, inflammatory, and childhood diseases. The institute also specializes in stem cell research and drug discovery technologies.
Matrix metalloproteinase-9 (MMP-9), also known as 92 kDa type IV collagenase, 92 kDa gelatinase or gelatinase B (GELB), is a matrixin, a class of enzymes that belong to the zinc-metalloproteinases family involved in the degradation of the extracellular matrix. In humans the MMP9 gene encodes for a signal peptide, a propeptide, a catalytic domain with inserted three repeats of fibronectin type II domain followed by a C-terminal hemopexin-like domain.
72 kDa type IV collagenase also known as matrix metalloproteinase-2 (MMP-2) and gelatinase A is an enzyme that in humans is encoded by the MMP2 gene. The MMP2 gene is located on chromosome 16 at position 12.2.
Matrix metalloproteinase-26 also known as matrilysin-2 and endometase is an enzyme that in humans is encoded by the MMP26 gene.
Matrix metalloproteinase-25 is an enzyme that in humans is encoded by the MMP25 gene.
A matrix metalloproteinase inhibitor inhibits matrix metalloproteinases. Because they inhibit cell migration, they have antiangiogenic effects. They are endogenous or exogenous.
Metalloprotease inhibitors are cellular inhibitors of the Matrix metalloproteinases (MMPs). MMPs belong to a family of zinc-dependent neutral endopeptidases. These enzymes have the ability to break down connective tissue. The expression of MMPs is increased in various pathological conditions like inflammatory conditions, metabolic bone disease, to cancer invasion, metastasis and angiogenesis. Examples of diseases are periodontitis, hepatitis, glomerulonephritis, atherosclerosis, emphysema, asthma, autoimmune disorders of skin and dermal photoaging, rheumatoid arthritis, osteoarthritis, multiple sclerosis, Alzheimer's disease, chronic ulcerations, uterine involution, corneal epithelial defects, bone resorption and tumor progression and metastasis. Due to the role of MMPs in pathological conditions, inhibitors of MMPs may have therapeutic potential. Several other proteins have similar inhibitory effects, however none as effective. They might have other biological activities which have yet been fully characterised.
Matrix metalloproteinase-21 (MMP-21) is an enzyme that in humans is encoded by the MMP21 gene.
Matrix metallopeptidase 27 also known as MMP-27 is an enzyme which in humans is encoded by the MMP27 gene.
Tanomastat is a non-peptidic biphenyl inhibitor of matrix metalloproteinases (MMPs), primarily studied for its potential to treat various types of cancer, including osteosarcoma and other malignancies.
Prinomastat is a matrix metalloproteinase (MMP) inhibitor with specific selectivity for MMPs 2, 3, 9, 13, and 14. Investigations have been carried out to determine whether the inhibition of these MMPs is able to block tumour metastasis by preventing MMP degradation of the extracellular matrix proteins and angiogenesis. Prinomastat underwent a Phase III trial to investigate its effectiveness against non-small cell lung cancer (NSCLC), in combination with gemcitabine chemotherapy. However, it was discovered that Prinomastat did not improve the outcome of chemotherapy in advanced non-small-cell lung cancer.
Kadmon Corporation is a biopharmaceutical company based in New York City. It also has operations in Warrendale, PA and Brighton, MA. The company was founded in 2009 by Samuel D. Waksal, founder and former CEO of ImClone Systems, a company now fully merged into Eli Lilly. Waksal had served a federal prison sentence stemming from his fiduciary role as CEO in the 2001 ImClone stock trading case. When released in 2009 he was barred from serving as an officer for any publicly traded company but Kadmon was privately financed.
Bisantrene is an anthracenyl bishydrazone with anthracycline-like antineoplastic activity and an antimetabolite. Bisantrene intercalates with and disrupts the configuration of DNA, resulting in DNA single-strand breaks, DNA-protein crosslinking, and inhibition of DNA replication. This agent is similar to doxorubicin in chemotherapeutic activity, but unlike anthracyclines like doxorubicin, it exhibits little cardiotoxicity.
