CHARACTERISTICS OF INDOLE AEROBIC DEGRADATION SLUDGE REINFORCE TRAINING AND THE RESEARCH OF DEGRADATION EFFICIENCY

To improve the treatment effect in the pharmaceutical wastewater in the biochemical system, the experiment domesticated efficient aerobic activated sludge to deal with wastewater deeply. In the presence of glucose co-matrix, indole was used as the characteristic pollutant to acclimate aerobic activated sludge by increasing pollutant concentration. The degradation characteristics and microbial characteristics during training were studied. The experimental results showed that indole could inhibit the growth of microorganisms in activated sludge, but after 2 months of intensive culture, activated sludge could adapt to the environment in which indole was the only carbon source. The bacteria species in the sludge were mainly Comamonas (34.18%) and Acinetobacter (15.45%), which could treat indole with a concentration of 200mg/L, the degradation efficiency was increased from 80% to more than 98.6%, and the SOUR value was stable at more than 7.61 mgO(2)/g MLSS.h, which was suitable for application in advanced treatment engineering of indole-containing pharmaceutical wastewater.

Trinuclear iron cluster and layered manganese complexes based on indolecarboxylic acid showing magnetic and antibacterial properties

Two novel iron and manganese complexes formulated as {[Fe-3(mu(3)-O)(H2O)(3)(I2CAH)(6)]center dot 2CH(3)OH center dot H2OCl}(n) (1) and {Mn(I2CAH)(2)(H2O)}(n) (2), (I2CAH(2) = Indole-2-carboxylic acid), have been synthesized by conventional solution method and structurally characterized. Compound 1 presents a triangular cluster structure consisting of trinuclear iron ions bridged by a mu(3)-O and chelated with six I2CAH(-) ligands. Compound 2 exhibits a two dimensional (2D) layered structure, which is formed by the I2CAH(-) ligand linked with manganese ions through a mono dentate bridging mode. Magnetic studies reveal the existence of antiferromagnetic interactions in compounds 1 and 2.

Glycyrrhizin, the active compound of the TCM drug Gan Cao stimulates actin remodelling and defence in grapevine

Actin remodelling by a membrane-associated oxidative process can sense perturbations of membrane integrity and activate defence. In the current work, we show that glycyrrhizin, a muscle relaxant used in Traditional Chinese Medicine, can activate oxidative burst and actin remodelling in tobacco BY-2 cells, which could be suppressed by diphenylene iodonium, an inhibitor of NADPH oxidases. Glycyrrhizin caused a dose-dependent delay of proliferation, and induced cell death, which was suppressed by addition of indole-acetic acid, a natural auxin that can mitigate RboH dependent actin remodelling. To test, whether the actin remodelling induced by glycyrrhizin was followed by activation of defence, several events of basal immunity were probed. We found that glycyrrhizin induced a transient extracellular alkalinisation, indicative of calcium influx. Furthermore, transcripts of phytoalexins genes, were activated in cells of the grapevine Vitis rupestris, and this induction was followed by accumulation of the glycosylated stilbene alpha-piceid. We also observed that glycyrrhizin was able to induce actin bundling in leaves of a transgenic grape, especially in guard cells. We discuss these data in frame of a model, where glycyrrhizin, through stimulation of RboH, can cause actin remodelling, followed by defence responses, such as calcium influx, induction of phytoalexins transcripts, and accumulation of stilbene glycosides.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 202189-78-4 help many people in the next few years. Computed Properties of C28H37N3O3.

Indole-3-Carbonitriles as DYRK1A Inhibitors by Fragment-Based Drug Design

Dual-specificity tyrosine phosphorylation-regulated kinase 1A (DYRK1A) is a potential drug target because of its role in the development of Down syndrome and Alzheimer’s disease. The selective DYRK1A inhibitor 10-iodo-11H-indolo[3,2-c]quinoline-6-carboxylic acid (KuFal194), a large, flat and lipophilic molecule, suffers from poor water solubility, limiting its use as chemical probe in cellular assays and animal models. Based on the structure of KuFal194, 7-chloro-1H-indole-3-carbonitrile was selected as fragment template for the development of smaller and less lipophilic DYRK1A inhibitors. By modification of this fragment, a series of indole-3-carbonitriles was designed and evaluated as potential DYRK1A ligands by molecular docking studies. Synthesis and in vitro assays on DYRK1A and related protein kinases identified novel double-digit nanomolar inhibitors with submicromolar activity in cell culture assays.
