Literature survey reveal that a good number of Anthracene and substituted Anthracene are potential lasing organic compounds. As per mit suo meada66 9,10-dimethyl and 9,10-diphenyl Anthracenes exhibit lasing properties, around 435-450 nm (ethanol). In continuation of our studies in this lab, our objective is to synthesize new lasing organic dyes, in particular, new Anthracene derivatives and stu...

A palladium(II) catalyst system has been identified for aerobic dehydrogenation of substituted cyclohexenes to the corresponding arene derivatives. Use of sodium anthraquinone-2-sulfonate (AMS) as a cocatalyst enhances the product yields. A wide range of functional groups are tolerated in the reactions, and the scope and limitations of the method are described. The catalytic dehydrogenation of ...

The transient absorption spectra and kinetics of excited triplet state of anthraquinone derivatives 2-anthraquinonesulfonatesodium (AQS) and 2deoxythymidine (dT) have been investigated in CH3CN-H2O (97:3) using the time-resolved laser flash photolysis technique (KrF, 248 nm). The absorption spectra of dT radical cation and the radical anion of AQS have been observed. From dynamic and thermodyrn...

In the last few decades, anthraquinone and its derivatives (AQs) have been intensively applied to electrochemical, textile dye, photovoltaic industries. This has increased levels of AQs in natural environment threatens human health. To remove from aqueous phase recover these multi-functional molecules, a binary magnetic adsorbent, reduced graphene/Fe3O4 (rGO/Fe3O4), was synthesized via hydrothe...

The synthesis of 1,5-dihydroxy-9,10-anthraquinone (17); (1,5-DHA) was accomplished during, attempts towards the synthesis one of its derivatives called anthralin (1,8-dihydroxy-9-anthrone) which is known as an antipsoriasis drug since 1916 [1]. This work is a new reigiospecilic preparation of 1,5-DHA based on Friedel-Crafts reaction starting from 1,4-dimethoxybenzene. This synthetic route, ...

Solutions of biologically active substances insoluble in water (thiosulfoesters, anthraquinone derivatives, pyrazoline) were obtained using a combined solvent and biogenic surfactants. For this purpose used rhamnolipids, their biocomplex with polysaccharides synthesized by the Pseudomonas SP strain. PS-17, trehalosolipids Rhodococcus erythropolis AU-1 strain, commercial biosurfactant surfactant...

The development of a ligand that is capable of distinguishing among the wide variety of G-quadruplex structures and targeting telomeres to treat cancer is particularly challenging. In this study, the ability of two anthraquinone telomerase inhibitors (NSC749235 and NSC764638) to target telomeric G-quadruplex DNA was probed. We found that these ligands specifically target the potassium form of t...

The structures of novel topoisomerase I inhibitors, topopyrones A, B, C and D were elucidated by spectral analysis of the chemical derivatives. These compounds are an anthraquinone type containing a fused 1,4-pyrone moiety. Topopyrones A and B contain a chlorine atom, however C and D do not. It was suggested that topopyrones B and D are converted from topopyrones A and C, respectively by Wessel...
