The Biological Activity of Retinotaurine
The Journal of Nutrition, 1982The ability of the biliary metabolite retinotaurine to reverse the cornification of vaginal epithelial cells induced by vitamin A deficiency was assessed using a vaginal smear assay. Retinotaurine activity was examined following the intravaginal administration of 10(-12) mol to 10(-8) mol of this compound per vagina.

Biologically active quinazolones
1994Quinazolinones form a large group among the pharmacologically active chemical moieties and are generally of little toxicity without serious side effects to the human body. Quinazolinones are versatile nitrogen heterocyclic compounds, displaying a broad spectrum of biological and pharmacological activities in animal as well as in human systems.

Biological activity of sterigmatocystin
Mycopathologia et Mycologia Applicata, 1968The biological activity of sterigmatocystin towards mice, ducklings, and some microorganisms was determined. The LD50 of sterigmatocystin for mice was in excess of 800 mg/kg. Aflatoxin B1 was 125 times more toxic in the ducklings tests than was sterigmatocystin.

Biological activities of oxysterols
Free Radical Biology and Medicine, 1989Literature 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 ...

The biological activity of fluorogibberellins
Planta, 1972The biological activities of gibberellin A9 (GA9), gibberellin A12 (GA12) and monofluoro-analogues (F-GA9 and F-GA12), substituted in the 1 β-methyl group, were compared in the barley endosperm, cucumber hypocotyl, lettuce hypocotyl, 'Meteor' dwarf pea, dwarf-5 maize and Rumex leaf disc assays.

Biological Activity of Silatranes
1978About 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).

Biological Activities of Complement
Biochemical Society Transactions, 1978Complement 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 Phosphoramidothionates
Nature, 1966IN 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.
