Emodin Pharmacokinetics in Rabbits

Planta Medica, 1995
Administration of emodin to rabbits by i.v. bolus resulted in a serum profile which could be well described by a two-compartment model. The AUC of emodin was 518 micrograms.min/ml, clearance was 72.3 ml/min, and elimination half life was 227 min which was much longer than that reported in a previous study.

Oxidation of emodin anthrone and stereochemistry of emodin bianthrone

Australian Journal of Chemistry, 1976
Synthetic emodin bianthrone is separated into meso - and (±)-diastereomers which are identified by means of an asymmetric p.m.r. shift reagent. They behave differently on mild oxidation. Both give protohypericin accompanied by an anthraquinone fraction but, whereas the major anthraquinone from the meso is emodin, the (k) gives chiefly the ...

Modification of emodin and aloe-emodin by glycosylation in engineered Escherihia coli

World Journal of Microbiology and Biotechnology, 2015
Glycosyltransferase from Bacillus licheniformis DSM13 (YjiC) was used for enzymatic modification of emodin and aloe-emodin in vitro and in vivo. In order to increase the availability of UDP-glucose, three genes involved in the production of precursors of NDP-sugar in Escherichia coli BL21 (DE3) viz.

Phosphorylation of emodin

Chemistry of Natural Compounds, 1994
A convenient method has been developed for the interaction of dialkyl phosphites with 1,6,8-trihydroxy-3-methylanthraquinone (emodin) under the conditions of the Todd—Atherton reaction. It has been shown that the α-hydroxy groups of emodin are not phosphorylated at an equimolar ratio of emodin and dialkyl phosphite. The phosphorylation of 7-bromo-1,6,8-

Bromination of emodin

Chemistry of Natural Compounds, 1990
Using emodin as an example, it has been shown that in the bromination of hydroxyanthraquinones the qualitative composition and quantitative ratio of the reaction products depend on the nature of the brominating agent and the solvent, the ratio of the rea Lants, and the temperature regime.
