Biological activities of oxysterols

Free Radical Biology and Medicine, 1989
Literature dealing with the biological activities of cholesterol autoxidation products and related oxysterols in vivo and in vitro published since the previous 1981 monograph is reviewed. Although several oxysterols are important cholesterol metabolites implicated in bile acids and steroid hormones biosynthesis, effects on cellular membranes and on ...

Biological Activity of Silatranes

1978
About 15 years ago we discovered high toxicity and specific biological activity of 1-arylsilatranes (1, 2) which, at that time, belonged to an almost unknown class of heterocyclic derivatives of penta-coordinate silicon with general formula (Fig. 1).

Biologically Active Organotin Polymers

Annals of the New York Academy of Sciences, 1985
The synthesis, structure, and properties of polymers in which tin is chemically anchored as tributyltin carboxylate are discussed. A base copolymer with anhydride or carboxyl groups is partially esterified with tributyltin oxide; the free carboxyls are then reacted with diepoxides to yield cross-linked controlled release formulations.

BIOLOGICAL ACTIVITIES OF HAMYCIN

Canadian Journal of Microbiology, 1966
After ad ministration of an oral dose to mice, hamycin, an antifungal antibiotic, penetrated the body tissues and eliminated Cryptococcus neoformans present in the lungs. Out of 11 polyenes (hamycin, aureofungin, trichomycin, etruscomycin, amphotericin B, pimaricin, mycostatin, candidin, candicidin, PA150, and filipin), hamycin and aureofungin showed ...

Biological Activity of Phosphoramidothionates

Nature, 1966
IN the course of our work on this class of compound an animal-anthelmintic1 and a selective herbicide2 had previously been discovered. Common to the structures of the two compounds was the linking of the phosphor-amidothionate group (I) to a chlorinated phenyl ring by an oxygen atom.

Biological activities of laminin

Journal of Cellular Biochemistry, 1985
AbstractLaminin is a multifunctional protein with diverse biological activities. Like fibronectin, it can influence cell adhesion, growth, morphology, differentiation, migration, and agglutination as well as the assembly of the extracellular matrix.

Biological Activities of Complement

Biochemical Society Transactions, 1978
Complement is a system of serum proteins whose main function is to defend the body against infection. Although it has a reputation as a dauntingly complex system, this results chiefly from confusion in the nomenclature, which has varied considerably with time as more components were discovered, for example as ‘component C3’ became subdivided into ...

Biological Activity of Purpurogallin

Bioscience, Biotechnology, and Biochemistry, 1997
Purpurogallin showed antibacterial activity toward gram-positive bacteria. Strong activity against methicillin-resistant Staphylococcus aureus [minimal inhibitory concentration (MIC) against methicillin of 1600 micrograms/ml] was found, with MIC of 11.0 micrograms/ml. Purpurogallin inhibited the growth of all tested plants and decreased the chlorophyll

Biologically Active Dietary Peptides

Mini-Reviews in Medicinal Chemistry, 2004
A large variety of peptides are generated in the gut lumen during normal digestion of dietary proteins. Large quantities of small peptides (ie. dipeptides and tripeptides) are absorbed through the gut mucosa and represent the primary mechanism for absorption of dietary nitrogen.

Biological Activities of Alginate

2014
To gain insight into the structure-activity relationship of alginate, we examined the effect of alginates with varying molecular weights and M/G ratio on murine macrophage cell line, RAW264.7 cells in terms of induction of tumor necrosis factor-α (TNF-α) secretion. Among the alginates tested, alginate with the highest molecular weight (MW 38,000, M/G 2.
