The concentrations of doxycycline and 4-de-dimethylaminotetracycline required to inhibit 50% of collagenase activity were found to be 15 to 30 microM for human neutrophil and gingival crevicular fluid collagenases. Fibroblast collagenase was relatively resistant to inhibition by tetracyclines; the 50% inhibitory concentrations of doxycycline and 4-de-dimethylaminotetracycline were 280 and 510 m...

We have developed collagenase-sensitive hydrogels by incorporating a collagenase-sensitive fluorogenic substrate (CS-FS) within the backbone of a polyethylene glycol (PEG) copolymer to visualize collagenase activity during three-dimensional cell migration. CS-FS was synthesized by conjugating Bodipy dyes to a peptide with collagenase-sensitive sequence, Leu-Gly-Pro-Ala (LGPA), and the products ...

Background: Today, the use of maggot therapy has become widespread due to the increase in chronic ulcers in the world. The recombinant production of secreted enzymes from these larvae is a novel non-invasive method for the treatment of chronic ulcers. Lucilia sericata (L. sericata) collagenase (MMP-1) has been expressed in insect cells. Collagenase is an enzyme that is widely used in clinical t...

Zoanthamine-type alkaloids display a wide spectrum of biological effects. This study aimed to examine the inhibitory effects of norzoanthamine and its ten homologues of zoanthamine class on human fibroblast collagenase by modeling a three-dimensional structure of the ligands at collagenase using energy minimization, docking, molecular dynamics simulation and MM-PB/GBSA binding free energy calcu...

Podisus maculiventris (Say) is a generalist predator attacking many insect species from different orders. The bug injects saliva into its prey’s body. The ingested hemolymph and liquefied internal tissues pass through the bug’s alimentary tract. Collagenase working on peptide bonds of collagen and basement membrane proteins, leads to the disintegration of the prey’s internal organs. As yet, the...

Rheumatoid synovial collagenase obtained from culture medium can be separated by Sephadex gel filtration into two peaks of enzyme activity. These have been designated as fast-moving and slow-moving rheumatoid synovial collagenases on the basis of their electrophoretic mobility on polyacrylamide gels. The slow-moving rheumatoid synovial collagenase has been highly purified by affinity chromatogr...

Bronchoalveolar lavage fluid from 43 patients with biopsy proved sarcoidosis and 10 control subjects were assayed for fibronectin and collagenase activity. Fibronectin was significantly increased in the group with sarcoidosis and was found to be positively correlated with angiotensin converting enzyme activity, protein concentration, percentage of T cells and helper:suppressor ratios in the lav...

Bioactive peptides produced from enzymatic hydrolysis fibrous protein have been proven to have several biological activities. Previous study showed that the hydrolysis product of snakehead fish skin collagen with 26 kDa collagenase from Bacillus licheniformis F11.4 showed HMG-CoA (HMGR) inhibition activity. The aim of this research was to determine the ability of the hydrolysis product produced...

An antibody against human skin collagenase obtained from tissue culture has been used to demonstrate the presence of immunoreactive collagenase in human skin extracts that have no detectable enzyme activity. Gel filtration of these skin extracts permits the separation of collagenase in its active form from the other proteins in the crude mixture. The recovery of enzymatically active collagenase...
