Evaluating the Fungistatic and Fungicidal Activities of Bianthrones as Synthetic Intermediates to Novel Hypericin Analogues.
… research is on the synthesis of anthraquinone, anthrone, bianthrone and hypericin type derivatives and the effect they have on the growth of the yeast species Schizosaccharomyces pombe, Lipomyces starkeyi andSaccharomyces cerevisiae. It is hoped that a new antifungal agent could be identified to …

Responses of Rumen Microbes to Excess Carbohydrate
… Methods compared were those based on the (i) anthrone reaction and (ii) hydrolysis with amyloglucosidase. Compared to the amyloglucosidase hydrolysis method, the anthrone method detected a larger increase (<i>P</i> = 0.017) in cell carbohydrate when glucose (20 m<i>M</i>) was dosed in …

A Quantitative Analysis of Solvent Effects on Keto-Enol Tautomeric Equilibria
… of dimedone, 2-methyl-1,3-cyclohexanedione, anthrone, acetylacetone, ethyl acetoacetate and 3-oxabicyclo{4.3.0}-2,9-dioxononane, representative of the major classes of (beta)-dicarbonyl and phenolic tautomeric equilibria, are determined in a variety of solvents by high dilution FT NMR and UV …

A Novel Mechanism of Skin Tumor Promotion Involving Interferon-Gamma (Ifnγ)/Signal Transducer and Activator of Transcription-1 (Stat1) Signaling In Epidermis
… Topical treatment with both TPA and the anthrone derivative chrysarobin (CHRY) led to rapid phosphorylation of Stat1 on both tyrosine (Tyr701) and serine (Ser727) residues in epidermis. CHRY treatment also led to upregulation of unphosphorylated Stat1 (uStat1) at later time points. In …

Some Aspects of Carbohydrate Metabolism in the Cercariae of SCHISTOSOMA MANSONI Sambon, 1907
… production, and respiration.</p> <p>Using the anthrone method of determination of carbohydrate, the amount of glycogen used by a single cercaria in 4 hours is determined as 43.2 x 10<sup>-4</sup> μg ± 6.6 x 10<sup>-4</sup> μg.</p> <p>Glucose was not observed to have been used from solution …

Synthesis, Characterization, and Mixed-Valence Studies of Conformationally Constrained Bisferrocenyl Complexes for the Study of Through-Space S***π; Interactions
… expected. Instead, the reaction of 1,8-dibromo-9-anthrone with Lawesson reagent afforded the intramolecular nucleophilic aromatic substitution cyclization product in quantitative yields. The reaction of the same anthrone under studied dithioketal formation conditions led to sulfur-rearrangement, …

Influence of flight activity and octopamine on hemolymph trehalose titers in Heliothis zea (Boddie) (Lepidoptera: Noctuidae)
… fed moths. Method of analysis (HPLC, HPTLC and anthrone) produced no differences in measured levels of trehalose or glucose. Various forms of stress (handling, shaking), also reported to induce hyperglycemia in other insects, similarly did not significantly increase trehalose titers in moths.

The Development and Evaluation of a Range of Phototherapeutic Dyes Towards Infection Control
… with the hydroxy anthraquinone and hydroxy bianthrone derivatives having a lower minimum inhibitory concentration when compared with fluconazole when illuminated with blue light. The hydroxy anthrone also showed the same minimum inhibitory concentration has fluconazole when illuminated with …

NOVEL G-QUADRUPLEX BINDERS WITH POTENTIAL FOR A DUAL DNA CROSS-LINKING MECHANISM OF ACTION
Genomic DNA is organized around the double-stranded of B-form DNA, which is both durable and flexible enough to store and pass on genetic information. Once freed from the associations of an extended complimentary sequence, single stranded DNA and RNA can adopt a vast array of stable secondary …
