This study reports the heterogeneous activation of sodium persulfate (SPS) by La0.8Sr0.2CoO3-delta (LSC) perovskite oxide for the degradation of sulfamethoxazole (SMX), a representative antibiotic agent. LSC was synthesized by a combustion method and characterized with respect to its physicochemical characteristics by means of nitrogen isotherm absorption (BET), X-ray diffraction (XRD), scanning electron microscopy (SEM/EDS) and transmission electron microscopy (TEM/HRTEM). LSC showed high activity towards SPS activation, resulting in complete SMX degradation in short time periods. The effect of SPS (100?500 mg/L), catalyst (100?500 mg/L) and SMX (0.125-0.5 mg/L) concentrations, as well as initial solution pH on SMX removal was studied. Apart from ultrapure water (UPW), additional experiments were conducted in bottled water (BW) and secondary treated wastewater (WW), showing the existence of retarding phenomena in SMX degradation. In order to further investigate these phenomena, experiments in UPW spiked with bicarbonate or chloride ions and humic acid were also carried out. The role of reactive oxygen species (sulfate and hydroxyl radicals) was determined with the use of suitable scavengers (methanol, t-butanol). Catalyst stability was assessed for five consecutive runs showing LSC superior recyclability. Coupling activators (LSC with simulated solar irradiation) resulted in faster SMX degradation in a synergistic rather than cumulative way.

Isoprenoids are a diverse family of compounds derived from the five-carbon precursors isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). Present in all domains of life, isoprenoids are essential for cell survival and participate in a variety of biological functions. Given that isoprenoids play a critical role in bacterial physiology and are utilized for cell wall biogenesis, membrane stability, protein synthesis, respiratory energy generation, and virulence, isoprenoid biosynthesis has been considered an attractive target for antibacterial drug discovery. Bacteria use one of two non-homologous pathways to produce IPP and DMAPP, the mevalonate pathway and the methylerythritol 4-phosphate pathway. As such, there are a multitude of essential enzymes that represent promising drug targets. Herein, the biochemical and cellular activities of antibacterial leads targeting isoprenoid biosynthesis are discussed.

Introduction: The bromodomain-containing protein 4 (BRD4), a member of the bromodomain and extra-terminal (BET) family, functions as an ?epigenetic reader? that binds to acetylated lysine (KAc) residues on histone tails sophisticatedly regulating chromatin structure and gene expression. Recently, emerging evidence demonstrates that BRD4 plays a significant role in the occurrence and progression of several malignant human diseases especially cancers, making it a hot target in cancer therapy. Areas covered: This review mainly summarizes the patents of BRD4 inhibitors that have been authorized from 2013 to 2019. The patents are mostly described in terms of chemical structures, molecular mechanisms of action, pharmacological activities and potential clinical applications, including combination therapies. The development of BRD4 inhibitors in the clinical phase has been highlighted. Prospects for further development of more selective BRD4 inhibitors are provided. Expert opinion: In 2013?2019, several previously known chemical scaffolds have been further developed and disclosed. Although many small molecule BRD4 inhibitors with high potency and diverse scaffolds have been developed, the selectivity of most BRD4 inhibitors still needs to be improved. Therefore, the development of more selective small molecule inhibitors or combined use of drugs such as immunotherapy may provide new ideas for drug development.

Nitrogen-doped graphene (NRGO) can activate peroxymonosulfate (PMS). However, the activation mechanism of PMS by NRGO needs to be further investigated. In this study NRGO was prepared by a facile method, and its activation mechanism of PMS for the degradation of sulfamethoxazole (SMX) was investigated. The XPS spectrum showed that nitrogen loading reached 16.5% (atomic percentage). The SMX removal efficiency reached 91.7% at 240 min in the NRGO-activated PMS system. During the PMS activation process, NRGO acted as dual roles: PMS activator and electron transfer mediator. NRGO can activate PMS to form singlet oxygen. In addition, NRGO can act as the electron transfer mediator to enhance the SMX degradation. Density functional theory (DFT) calculations demonstrated that nitrogen doping increased the charge density of net positive carbon atoms and decreased the energy gap, further enhancing the PMS activation. The effects of pH, temperature and the concentrations of chloridion and humic acid were investigated. NRGO had good stability in activating PMS evidenced by the cycling experiments. Eight degradation intermediate products of SMX was identified. Among them, 3-amino-5-methyl-isoxazole and 4-nitro-SMX presented high abundance. The acute toxicity of treated SMX solution increased, suggesting that the degradation products of SMX formed in the non-radicals? process should be concerned. This study provided an insight into the SMX degradation by NRGO-activated PMS including the mechanisms of PMS activation and SMX degradation.

Abstract: Novel nitro (3a?3f)- and amino (4a?4f and 5a?5f)-substituted 2-benzimidazolyl and 2-benzothiazolyl benzo[b]thieno-2-carboxamides were designed and synthesized as potential antibacterial agents. The antibacterial activity of these compounds has been evaluated against Gram-positive (Staphylococcus aureus and Enterococcus faecalis) and Gram-negative bacteria (Escherichia coli and Moraxella catarrhalis). The most promising antibacterial activity was observed for the nitro- and amino-substituted benzimidazole derivatives 3a, 4a, 5a and 5b with MICs 2?8 mu g/mL. Additionally, compounds with inferior antibacterial activity were further tested for their antiproliferative activity in vitro against three human cancer cell lines. Amino-substituted benzothiazole hydrochloride salt 5d displayed the most pronounced and selective activity against the MCF-7 cell line with an IC 50 of 40 nM. Furthermore, DNA binding experiments of selected derivatives indicated that DNA cannot be considered as a primary biological target for this type of compounds.

The objective of this research is to generate leads for developing our ultimate poly-active molecules with utility in central nervous system (CNS) diseases. Indeed, poly-active molecules capable of mitigating brain free radical damage while enhancing acetylcholine signaling (via cholinesterase inhibition) are still being sought for combating Alzheimer?s disease (AD). We differentiate ?poly-active? agents from ?multi-target? ones by defining them as single molecular entities designed to target only specific contributory synergistic pharmacologies in a disease. For instance, in AD, free radicals either initiate or act in synergy with other pharmacologies, leading to disease worsening. For this preliminary report, a total of 14 (i.e., 4,5-dimethoxy-2-nitrobenzohydrazide plus 1-(1-benzylpiperidin-4-yl)ethan-1-one) derivatives were synthesized and screened, in silico and in vitro, for their ability to scavenge free radicals and inhibit acetylcholinesterase (AChE)/butyrylcholinesterase (BuChE) enzymes. Overall, six derivatives (4a, 4d, 4e, 4f, 4g, 9b) exhibited potent (>30%) antioxidant properties in the oxygen radical absorbance capacity (ORAC) assay. The antioxidant values were either comparable or more potent than the comparator molecules (ascorbic acid, resveratrol, and trolox). Only three compounds (4d, 9a, 9c) yielded modest AChE/BuChE inhibitions (>10%). Please note that a SciFinder substance data base search confirmed that most of the compounds reported herein are new, except 9a and 9c which are also commercially available.

The use of B(OCH2CF3)3 for mediating direct amidation reactions of a wide range of pharmaceutically relevant carboxylic acids and amines is described, including numerous heterocycle-containing examples. An initial screen of solvents for the direct amidation reaction suggested that cyclopentyl methyl ether, a solvent with a very good safety profile suitable for use over a wide temperature range, was an excellent replacement for the previously used solvent acetonitrile. Under these conditions amides could be prepared from 18 of the 21 carboxylic acids and 18 of the 21 amines examined. Further optimisation of one of the low yielding amidation reactions (36% yield) via a design of experiments approach enabled an 84% yield of the amide to be obtained.
