Applications of TEMPO(.)catalysis for the development of redox-neutral transformations are rare. Reported here is the first TEMPO.-catalyzed, redox-neutral C-H di- and trifluoromethoxylation of (hetero)arenes. The reaction exhibits a broad substrate scope, has high functional-group tolerance, and can be employed for the late-stage functionalization of complex druglike molecules. Kinetic measurements, isolation and resubjection of catalytic intermediates, UV/Vis studies, and DFT calculations support the proposed oxidative TEMPO./TEMPO(+)redox catalytic cycle. Mechanistic studies also suggest that Li(2)CO(3)plays an important role in preventing catalyst deactivation. These findings will provide new insights into the design and development of novel reactions through redox-neutral TEMPO(.)catalysis.

In our present investigation, a series of novel 4-methoxy-1,3-benzenediolyl-hydrazones were designed and synthesized, and their ability to inhibit platelet aggregation was evaluated by adenosine diphosphate (ADP) and arachidonic acid (AA). The structures of the synthesized compounds were confirmed by spectral data. Results demonstrated that the activities of all compounds excelled the positive drug Picotamide (25.1% inhibition rate) and seven compounds (PNN01, PNN03, PNN05, PNN07, PNN09, PNN12, and PNN14) have efficiently inhibited platelet aggregation even higher than Clopidogrel (37.6% inhibition rate) induced by AA. Among them, PNN07 (39.8% inhibition rate) was considered as the most potent analogue. Evaluation of cytotoxic activity of the compounds against L929 cell line revealed that none of the compounds have significant cytotoxicity. Thus, diolylhydrazones derives are potential to be antiplatelet aggregation inhibitors and maybe working in AA-induced selectively.

Outfitting an aza-crown ether with an organotransition-metal pendant provides a mechanism for tuning its supramolecular properties. The binding affinity can be tuned by more than 2 orders of magnitude by changing the identity of the transition metal-center, altering the overall charge of the complex, or engaging in organometallic ligand substitution reactions. High Li+ selectivity (up to 29-fold higher affinity in comparison to Na+), proton-responsive behavior, and ion pair (ditopic) binding capabilities are observed in the metallacrown ethers.

The synthesis of aminocarbonyl derivatives as biologically active compounds by using polyethylene glycol (PEG-400)-SO3H-coated Fe2O3 is reported. The heterogeneous nanocatalyst was prepared via in-situ co-precipitation method and its structure and morphology was characterized by Fourier-transform infrared spectroscopy, energy-dispersive X-ray analysis, X-ray diffraction pattern, field-emission scanning electron microscopy image, vibrating sample magnetometer curves, N-2 adsorption-desorption isotherm and inductively-coupled plasma analysis. Noteworthy, the green composite nanocatalyst was applied for the one-pot multicomponent synthesis of aminocarbonyl compounds at room temperature. This work had advantages such as significant nanocatalyst activity, recoverability, short process time, mild reaction conditions and high products yields.

The gold(I)-catalyzed reaction of bromoalkynes with allylsilanes gives 1,4-enynes in a formal cross-coupling reaction. Mechanistic studies revealed the involvement of gold(I) vinylidenes or vinylidenephenonium gold(I) cations depending on the substituent on the bromoalkyne. In the case of bromo arylalkynes, the vinylidenephenonium gold(I) cations lead to 1,4-enynes via a 1,2-aryl rearrangement. The same reactivity has been observed in the presence of InBr3.

Two series of novel morpholinopyrimidine derivatives were synthesized and screened for their in-vitro cytotoxic activity against 60 tumor cell line by the National Cancer Institute, USA. The in-vitro cytotoxic IC50 values for the most active compounds 6e, 6g, and 6l against the most sensitive cell line leukemia SR were estimated (IC50 = 0.76, 13.59, and 4.37 uM, respectively). To investigate their PI3K enzyme inhibition activity, the assay was done on Class IA (alpha, beta, & delta) isoforms. The IC50 values were very promising: compound [6e = 11.73 (alpha), 6.09 (beta), 11.18 (delta)], compound [6g = 8.43 (alpha), 15.84 (beta), 30.62 (delta)], and compound [6l = 13.98 (alpha), 7.22 (beta), 10.94 (delta)], compared to the reference compound LY294002 = 6.28 (alpha), 4.51 (beta), 4.60 (delta) uM, respectively. Moreover, cell cycle analysis and annexin V-FITC staining were done on Leukemia SR, there was arrest at G2/M phase and apoptosis was induced. Finally, docking study was performed to analyze the interactive mode of these derivatives in PI3K alpha ATP-binding site. These outcomes proved that compounds 6e, 6g, and 6l are potential leads for further optimization as antileukemic agents.

Herein, an efficient versatile nanocomposite constructed of melamine-functionalized graphene oxide nano-sheets (GO@melamine), iron oxide nanoparticles (Fe3O4 NPs), and zinc oxide (ZnO NPs) is presented. Moreover, two different applications have been studied for the prepared Fe3O4/GO@melamine-ZnO nanocomposite: First, as a heterogeneous catalyst for synthesis of pyrano[2,3-c]pyrazole derivatives in short reaction time (10 min) with high yields (96 %), second, as a substantial electrical supercapacitor with typical capacitive behavior, high resistance, and excellent electrode stability. From the catalytic aspect, high effectiveness, convenient isolation, and significant reusability could be referred as the distinguished properties for the produced nanocomposite. Turn-over number (TON) and turn-over frequency (TOF) values for the presented catalytic system have been estimated 17.2 x 10(6) and 1.71 x 10(6) min(-1), respectively, which revealed high catalytic performance of this catalytic system. From electrochemical aspect, economic benefits for fabrication of the introduced nanocomposite containing low-cost materials, make it as a suitable electrical supercapacitor for industrial applications.

The worldwide use of the broad-spectrum antimicrobial trimethoprim (TMP) has induced the rise of TMP-resistant microorganisms. In addition to resistance-causing mutations of the microbial chromosomal dihydrofolate reductase (Dfr), the evolutionarily and structurally unrelated type II Dfrs (DfrBs) have been identified in TMP-resistant microorganisms. DfrBs are intrinsically TMP-resistant and allow bacterial proliferation when the microbial chromosomal Dfr is TMP-inhibited, making these enzymes important targets for inhibitor development. Furthermore, DfrBs occur in multiresistance plasmids, potentially accelerating their dissemination. We previously reported symmetrical bisbenzimidazoles that are the first selective inhibitors of the only well-characterized DfrB, DfrB1. Here, their diversification provides a new series of inhibitors (K-i = 1.7-12.0 mu M). Our results reveal two prominent features: terminal carboxylates and inhibitor length allow the establishment of essential interactions with DfrB1. Two crystal structures demonstrate the simultaneous binding of two inhibitor molecules in the symmetrical active site. Observations of those dimeric inhibitors inspired the design of monomeric analogues, binding in a single copy yet offering similar inhibition potency (K-i = 1.1 and 7.4 mu M). Inhibition of a second member of the DfrB family, DfrB4, suggests the generality of these inhibitors. These results provide key insights into inhibition of the highly TMP-resistant DfrBs, opening avenues to downstream development of antibiotics for combatting this emergent source of resistance.
