Quinones are widely found in nature, used in chemistry and medicine, and are just beginning to gain importance in materials engineering. In order to harvest their potential as an ordered or highly crystalline solid, their crystal formation processes need to be well investigated and controlled. We chose 1,4-anthraquinone, a commercially available type of quinone, as a model compound to study its...

We have reviewed published anthraquinone applications for international pest management and agricultural crop protection from 1943 to 2016. Anthraquinone (AQ) is commonly found in dyes, pigments and many plants and organisms. Avian repellent research with AQ began in the 1940s. In the context of pest management, AQ is currently used as a chemical repellent, perch deterrent, insecticide and feed...

A water-soluble anthraquinone derivative (2-[methylamino-N-(1 0-methylethyl)]-9,10-anthraquinone monophosphate), previously found to be selectively toxic towards Planktothrix perornata at submicromolar concentrations, was studied to determine its toxic mode of action towards this cyanobacterium. Chlorophyll fluorescence was monitored as an indicator of photosynthetic efficiency, and measurement...

Rheum species are medicinally important herbs, posses several type of biological activities due to the presence of anthraquinone derivatives. Several HPLC methods have been used for sepeatation of anthraquinone of Rheum Species. In most cases anthraquinones were separated using C18 column as a stationary phase, acetonitrile, water and methanol with or without acid as mobile phase at 1.0 ml/min ...

Application strategies for avian repellents are needed to maintain efficacious repellent concentrations throughout the period of needed crop protection. We investigated the repellency of an ultraviolet (UV) feeding cue in the absence of postingestive consequences, the combination of the UV feeding cue and an UV-absorbent, postingestive repellent (i.e., a repellent that causes negative postinges...

The effect of anthraquinone derivatives (anthraquinone, sodium anthraquinone T-sulfonate, anthrarufin and enthrone) and other compounds (a-naphthoquinone, lecithin and tannic acid) on progestational proliferation produced by progesterone in the rabbit uterus was investigated by measurements of endometrial carbonic anhydrase activity. In immature rabbits primed with estrogen, the subcutaneous ad...

The synthesis of a 2'-deoxyuridine nucleoside linked to an anthraquinone moiety, and its incorporation into oligonucleotides are described, including a facile oxidative demethylation with phenyliodine(iii) bis(trifluoroacetate) to reveal the anthraquinone motif. Furthermore, some useful physical and electrochemical properties of the obtained oligonucleotide are also reported, which allow its pr...
