We investigated the relative effectiveness of four differentiation-inducing chemicals to induce a more normal or benign phenotype in the human colon cancer cell lines Moser and HT29. The differentiation-inducing capability of all-trans retinoic acid (ATRA), difluoromethylornithine (DFMO), sodiu...
LiV3O8/10wt% poly(1,5-diaminoanthraquinone) composite was prepared by a in situ chemical oxidative polymerization process and applied as cathode material for rechargeable lithium batteries. Due to the introduction of poly(1,5-diaminoanthraquinone) and electrochemical synergistic effect, the comp...
Semiconducting coordination complexes have been synthesized by the oxidation of 1,5-diaminoanthraquinone (1,5-DAAQ) using Cu(NO 3 ) 2 , CuCl, Ni(NO 3 ) 2 , AgNO 3 , PdCl 2 , FeCl 3 and ceric ammonium nitrate. Anionic oxidants like K 2 ...
Supramolecular conducting oligomeric 1,5-diaminoanthraquinone (DAAQ)-based all solid-state redox supercapacitors have been fabricated with the solid polymer electrolyte, poly vinyl alcohol (PVA)-H 3 PO 4 blend and polymeric gel electrolyte poly methyl methacrylate (PMMA)-ethylene...
In this study, we used thermal evaporation with a low sublimation temperature (42°C) to deposit 1,5-diaminoanthraquinone (DAAQ) in various morphologies—including nanorods, nanocornerstones, and nanofibers—onto various substrates. Three major factors influenced the growth of vertically aligned...
Nowadays, high energy density is greatly imperative for supercapacitor technologies, which focus on both high-performance electrodes and assembling techniques. Here, we synthesized a promising cathode of graphene/acid-treated carbon nanotubes (GNS/aMWCNT)-supported polyaniline nanocone arrays by...
Condensation of 2-substituted-1,4-dihydroxyanthraquinones with 2-amino-benzenethiol generally results in the elimination of the 2-substituent and formation of 7-hydroxy-14H-naphtho[2,3-a]phenothiazine-8,13-dione (I). In addition to the anticipated replacement of labile 2-substituents such as ha...
The induction of a variety of drug-metabolizing enzymes by six anthraquinones (AQs) has been investigated in the liver and small intestine of rat. In the liver, the intragastric administration for 3 days of 100 mg/kg 9,10-anthraquinone (9,10-AQ), 1-hydroxy-AQ, 1,4-dihydroxy-AQ, but not 1,2-dihyd...
Electrochemical properties of a 1-hydroxy-anthraquinone derivative (1-hydroxyAQ) self-assembled monolayer (SAM) were studied using reflectance infrared, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The results of the electrochemical investigation into the proton-coup...
A sensitive gas chromatographic method for the determination of the quinoline alkaloid viridicatin, a fungal metabolite isolated from severalPenicilliumspecies and presumably a biogenetic precursor to naturally occurring diazepam-like 1,4-benzo-diazepines, has been developed. Prior to conversion...
The 6,6‐quinolone scaffold of the viridicatin‐type of fungal alkaloids are found in various quinolone alkaloids which often exhibit useful biological activities. Thus, it is of interest to identify viridicatin‐forming enzymes and understand how such alkaloids are biosynthesized. Here an Asper...
Matrix metalloproteinases (MMPs), the key enzymes in extracellular matrix degradation, seemed to increase in tumorigenesis, which has a relationship with metastasis and invasions. In this study, we investigated the MMP inhibitory effect of viridicatol and viridicatin, two compounds extracted fro...
3‐Alkyl/aryl‐3‐hydroxyquinoline‐2,4‐diones were reduced with NaBH4 to give cis‐3‐alkyl/aryl‐3,4‐dihydro‐3,4‐dihydroxyquinolin‐2(1H)‐ones. These compounds were subjected to pinacol rearrangement by treatment with concentrated H2SO4, resulting in 4‐alkyl/aryl‐3‐hydroxyquinolin‐2(1...
We present here the NHC‐dirhodium(II)/DBU‐catalyzed ring expansion reaction of isatins with ethyl diazoacetate. This new one‐pot protocol yields the ethyl 3‐hydroxy‐2(1H)‐oxoquinoline‐4‐carboxylate core, regioselectively and in good to excellent yields. A DFT mechanistic study indicates ...
Quality loss inhibition in chilled blue whiting (Micromesistius poutassou) was investigated. For it, a natural organic acid‐mixture including ascorbic, citric and lactic acids was applied in a two‐step processing strategy: (i) as an aqueous dipping medium previous to chilling storage and, (ii)...
Basic violet 3 (BV) and acid blue 93 (AB) belong to the most important group of synthetic colorants. These dyes are used extensively in textile, paper, and leather industries. It is considered as xenobiotic compound, which is recalcitrant to biodegradation. Pseudomonas putida MTCC 4910 was able ...
The present study describes the potential of Chrome Shavings (CS), a tannery waste, for the removal of AB 45 dye. A Central Composite Design was employed for framing the experimental design matrix. To facilitate the optimization of various batch parameters (pH, adsorbent dosage and initial dye c...
The responses of estuarine invertebrates to hypoxic conditions are well established. However, many studies have investigated hypoxia as an isolated condition despite its frequent co‐occurrence with hypercapnia (elevated CO2). Although many studies suggest deleterious effects, hypercapnia has be...
Two coordination polymers of assorted dimensionality (1D, 2D) have been prepared, namely [Zn3(L2Th)4(OH)2·2(HL2Th)]∞ (1) and [Zn(L5Th)(OAc)]∞ (2), starting from ZnII salts and the isomeric forms of the organic linker p‐(thiazolyl)benzoic acid: p‐(2‐thiazolyl)benzoic acid (HL2Th) and p‐(5‐...
