Inhibition of human leukocyte elastase activity by chondroitin sulfates

open access: yesChemico-Biological Interactions, 1997
Chondroitin sulfates with different properties and devoid of appreciable anticoagulant activity were evaluated for their capacity to inhibit human leukocyte elastase activity in vitro by using a chromogenic substrate.

Production of chondroitin sulfate and chondroitin

Applied Microbiology and Biotechnology, 2010
The production of microbial polysaccharides has recently gained much interest because of their potential biotechnological applications. Several pathogenic bacteria are known to produce capsular polysaccharides, which provide a protection barrier towards harsh environmental conditions, and towards host defences in case of invasive infections.

Glucosamine and Chondroitin Sulfate

Rheumatic Disease Clinics of North America, 2011
Glucosamine and chondroitin sulfate, components of normal cartilage that are marketed as dietary supplements in the United States, have been evaluated for their potential role in the treatment of osteoarthritis. Due to claims of efficacy, increased prevalence of osteoarthritis, and a lack of other effective therapies, there has been substantial ...

The biosynthesis of chondroitin sulfate

Archives of Biochemistry and Biophysics, 1966
Abstract A particulate enzyme preparation from embryonic chick cartilage catalyzes incorporation of radioactivity from UDP-GalNAc- 3 H or UDP-Glc-UA- 14 C into chondroitin sulfate. In the absence of added oligosaccharide acceptor, incorporation of radioactivity from either nucleotide required the presence of the alternate unlabeled nucleotide ...

Modeling glycosaminoglycans—hyaluronan, chondroitin, chondroitin sulfate A, chondroitin sulfate C and keratan sulfate

Journal of Molecular Structure: THEOCHEM, 2004
Abstract Molecular modeling of glycosaminoglycans, hyaluronan, chondroitin, chondroitin-4-sulfate, chondroitin-6-sulfate and keratan sulfate is presented. Semiempirical quantum mechanical calculations, PM3 method, have been used to locate the minimal energy regions in the conformational space around the β 1→3 and β 1→4 glycosidic linkages. The global

Structure of Chondroitin Sulfate

2006
Publisher Summary This chapter presents the up‐to‐date information on the structure of chondroitin sulfate (CS) and dermatan sulfate (DS). CS is an anionic linear polysaccharide, which is synthesized as part of proteoglycan (PG) molecules in vertebrates and invertebrates.

Synthesis of Chondroitin Sulfate Oligosaccharides and Chondroitin Sulfate Glycopeptides

2019
Chondroitin sulfate (CS) and chondroitin sulfate proteoglycan (CSPG) belong to the glycosaminoglycan (GAG) family, a class of poly-anionic glyco-conjugates widely expressed by animal cells. They play important roles in many biological events. Here, we summarize the main considerations in the design of chemical and enzymatic methodologies to access ...

Biosynthesis and function of chondroitin sulfate

Biochimica et Biophysica Acta (BBA) - General Subjects, 2013
Chondroitin sulfate proteoglycans (CSPGs) are principal pericellular and extracellular components that form regulatory milieu involving numerous biological and pathophysiological phenomena. Diverse functions of CSPGs can be mainly attributed to structural variability of their polysaccharide moieties, chondroitin sulfate glycosaminoglycans (CS-GAG ...

Calcium binding by chondroitin sulfate

Calcified Tissue Research, 1968
The binding of calcium by chondroitin sulfate C was studied by employing biological and physicochemical methods for the quantitative determination of ionic calcium. Mean values for logKj, the logarithm of the uncorrected formation constant for a calcium-chondroitin sulfate complex, were 1.64 with the frog heart technique, 1.55 with the murexide method,
