We report the synthesis, optoelectronic properties, and electrical switching memory characteristics of three new donor-acceptor oligoimides consisting of the electron-donating moieties (triphenylamine or carbazole) and electron-withdrawing phthalimide moieties. The influence of different donor (D)-acceptor (A) arrangements, including D-A-D and A-D-A structures, on the electrical properties was explored. Devices based on D-A-D oligoimides revealed a reversible nonvolatile negative-differential-resistance (NDR) characteristic and excellent stability during operation. Without applying voltage stress, the on and off states of the devices showed no obvious degradation for an operation time of 10 s and 108 read pulses. However, the devices prepared from the A-D-A oligoimide showed only the insulating properties. The different memory characteristic was probably because the terminal donor moieties in the D-A-D structure might facilitate the injection and transporting of the holes. Besides, the D-A-D oligoimide with triphenylamine groups exhibited an on/off ratio of 104, 2 orders of magnitude higher than that with carbazole groups. The mechanism related to electrical switching properties was elucidated through molecular simulation. Thus the significance of D-A-D structure on tuning memory characteristics for memory device applications was revealed.

Aurones and auronols are naturally occurring 2-benzylidenebenzof-uranone- 3(2H)-one derivatives. Aurones have a limited occurrence in fruits, vegetables, and bright yellow color to flowers such as cosmos and coreopsis. Aurones possess a wide range of biological activities, such as antitumor, antifungal, phytoalexin, and so on. Some aurone derivatives have been studied as antitumor drug molecules, but 2-benzylidene-5-bromobenzofuranone-3(2H)-one series have not been reported yet. In this paper, we’d like to report the design, synthesis, and biological evaluation of the novel aurone derivatives. All the newly synthesized compounds were characterized by 1H NMR and their antitumor activities were evaluated by using MTT method in HT-29, K562, and HepG2 cell lines. 5-bromo-2-(4-nitrobenzylidene) benzofuran-3(2H)-one demonstrated good antitumor activity against K562 cells with an IC50 of 0.37 lM.

The development of a gold(III) catalyzed direct enantioconvergent 1,5-enyne cycloisomerization and kinetic resolution reaction is described. The transformation results in highly enantioenriched bicyclo[3.1.0]hexenes at all levels of conversion, with no racemization or symmetrization taking place during the course of the reaction, and simultaneously affords optically enriched 1,5-enynes. This report marks the first highly enantioselective transformation catalyzed by a well-defined cationic gold(III) catalyst and demonstrates the unique potential of gold(III) complexes in enantioselective catalysis.

Electric Literature of 496-41-3, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 496-41-3, molcular formula is C9H6O3, introducing its new discovery.

A new series of heteroaromatic GBR 12935 [1-[2-(diphenylmethoxy)ethyl]- 4-(3-phenylpropyl)-piperazine] (1) and GBR 12909 [1-[2-[bis(4- fluorophenyl)methoxy]ethyl]-4-(3-phenylpropyl)-piperazine] (2) analogs was synthesized and evaluated as dopamine transporter (DAT) ligands. Analogs 5- 16, in which the benzene ring in the phenylpropyl side chain of the GBR molecule had been replaced with a thiophene, furan, or pyridine ring, exhibited high affinity and selectivity for the DAT vs serotonin transporter (SERT) and stimulated locomotor activity in rats in a manner similar to the parent compound 2. In cocaine and food self-administration studies in rhesus monkeys, both thiophene-containing (6 and 8) and pyridine-containing (14 and 16) derivatives displayed potency comparable to 2 in decreasing the cocaine- maintained responding at the doses tested (0.3, 1.7, and 3 mg/kg). However, these compounds did not produce the degree of separation between food- and cocaine-maintained responding that was seen with 2. Among the bicyclic fused- ring congeners 17-38, the indole-containing analog of 2, 22, showed the greatest affinity for binding to the DAT, with IC50 = 0.7 nM, whereas the corresponding indole-containing derivative of 1, 21, displayed the highest selectivity (over 600-fold) at this site vs the SERT site.

Antimicrobial resistance has become a major global concern. Development of novel antimicrobial agents for the treatment of infections caused by multidrug resistant (MDR) pathogens is an urgent priority. Pyrrolobenzodiazepines (PBDs) are a promising class of antibacterial agents initially discovered and isolated from natural sources. Recently, C8-linked PBD biaryl conjugates have been shown to be active against some MDR Gram-positive strains. To explore the role of building block orientations on antibacterial activity and obtain structure activity relationship (SAR) information, four novel structures were synthesized in which the building blocks of previously reported compounds were inverted, and their antibacterial activity was studied. The compounds showed minimum inhibitory concentrations (MICs) in the range of 0.125-32 mug/mL against MDR Gram-positive strains with a bactericidal mode of action. The results showed that a single inversion of amide bonds reduces the activity while the double inversion restores the activity against MDR pathogens. All inverted compounds did not stabilize DNA and lacked eukaryotic toxicity. The compounds inhibit DNA gyrase in vitro, and the most potent compound was equally active against both wild-Type and mutant DNA gyrase in a biochemical assay. The observed activity of the compounds against methicillin resistant S. aureus (MRSA) strains with equivalent gyrase mutations is consistent with gyrase inhibition being the mechanism of action in vivo, although this has not been definitively confirmed in whole cells. This conclusion is supported by a molecular modeling study showing interaction of the compounds with wild-Type and mutant gyrases. This study provides important SAR information about this new class of antibacterial agents.
