BACKGROUND Both positive expectancies regarding the effects of alcohol and internalizing problems, including negative emotionality and deficits in emotion regulation, are known risk factors for alcohol use disorder (AUD). The current study is the first to investigate how neural response to emotional stimuli may impact alcohol expectancies and risk for AUD. METHODS Functional neuroimaging data was collected during an emotional word task from 168 emerging adults (M age = 19.65; 66% male). Activation to negative versus neutral words and positive versus neutral words was extracted for analyses. Participants also reported on their alcohol expectancies and information regarding alcohol use and problems was collected prospectively throughout adolescence and into adulthood (up to age 30). RESULTS Decreased activation in the inferior frontal gyrus (IFG) to negative versus neutral words was associated with increased post-scan alcohol consumption, measured as average drinks per year. There was a significant indirect effect of positive alcohol expectancies on the association between IFG activation and post-scan alcohol consumption, even when controlling for quantity of alcohol consumption prior to the scan. CONCLUSIONS These results are the first to provide evidence that positive alcohol expectancies account for variance shared between brain regions associated with emotion processing and increased drinking behaviors. Alcohol expectancies may provide a modifiable target for treatments to decrease the link between deficits in emotion regulation and increased alcohol use. V.BACKGROUND Models of health disparities highlight stress among low socioeconomic status (SES) smokers as a barrier to cessation. Recent studies suggest that mindfulness may improve cessation outcomes by reducing stress during a quit attempt. The current study examined associations of SES and mindfulness with ecological momentary assessments (EMAs) of stress and smoking lapse during a quit attempt. METHODS EMAs (N = 32,329) were gathered from 364 smokers engaged in a quit attempt. A multilevel structural equation model estimated within person paths from momentary stress to subsequent smoking lapse. Between person paths estimated paths from a latent variable for SES and mindfulness to stress and smoking lapse, the indirect effect of SES and mindfulness on lapse through stress, and moderation of within person stress-lapse associations by SES and mindfulness. RESULTS Within person estimates found that momentary increases in stress predicted increased risk of subsequent smoking lapse. Between person estimates found that lower SES was indirectly associated with greater risk for smoking lapse through increased stress; and, higher mindfulness was indirectly associated with lower risk for smoking lapse through reduced stress. Additionally, higher SES participants, who reported lower stress during the quit attempt, showed a stronger relationship between momentary increases in stress and risk for subsequent smoking lapse. CONCLUSIONS Among low SES smokers engaged in a quit attempt, both SES and mindfulness uniquely influenced smoking lapse through their influence on stress. Findings support reports that mindfulness presents a promising intervention target to reduce stress and improve cessation outcomes among low SES smokers. The amide functional group is ubiquitous in nature and one of the most important motifs in pharmaceuticals, agrochemicals, and other valuable products. While coupling amides and carboxylic acids is a trivial synthetic transformation, it often requires protective group manipulation, along with stoichiometric quantities of expensive and deleterious coupling reagents. Nature has evolved a range of enzymes to construct amide bonds, the vast majority of which utilize adenosine triphosphate to activate the carboxylic acid substrate for amine coupling. Despite the fact that these enzymes operate under mild conditions, as well as possessing chemoselectivity and regioselectivity that obviates the need for protecting groups, their synthetic potential has been largely unexplored. In this review, we discuss recent research into the discovery, characterization, and development of amide bond forming enzymes, with an emphasis on stand-alone ligase enzymes that can generate amides directly from simple carboxylic acid and amine substrates. Novel ethyl 2-(5-aryl-1H-imidazol-1-yl)-acetates 17 and propionates 18, together with their acetic acid 19 and acetohydrazide 20 derivatives, were designed and synthesized using TosMIC chemistry. Biological evaluation of these newly synthesized scaffolds in the HIV-1 Vpu- Host BST-2 ELISA assay identified seven hits (17a, 17b, 17c, 17g, 18a, 20f and 20g) with greater than 50% inhibitory activity. These hits were validated in the HIV-1 Vpu- Host BST-2 AlphaScreen™ and six of the seven compounds were found to have comparable percentage inhibitory activities to those of the ELISA assay. selleckchem Compounds 17b and 20g, with consistent percentage inhibitory activities across the two assays, had IC50 values of 11.6 ± 1.1 μM and 17.6 ± 0.9 μM in a dose response AlphaScreen™ assay. In a cell-based HIV-1 antiviral assay, compound 17b exhibited an EC50 = 6.3 ± 0.7 μM at non-toxic concentrations (CC50 = 184.5 ± 0.8 μM), whereas compound 20g displayed antiviral activity roughly equivalent to its toxicity (CC50 = 159.5 ± 0.9 μM). This data suggests that compound 17b, active in both cell-based and biochemical assays, provides a good starting point for the design of possible lead compounds for prevention of HIV-1 Vpu and host BST-2 protein binding in new anti-HIV therapeutics. Aurora A kinase, a member of the Aurora kinase family, is frequently overexpressed in various human cancers. In addition, Overexpression of Aurora A kinase is associated with drug resistance and poor prognosis in many cancers including breast cancer. Therefore, Aurora A kinase has been considered as an attractive anticancer target for the treatment of human cancers. Herein, A series of 6-(2-amino-1H-benzo[d]imidazole-6-yl)quinazolin-4(3H)-one derivatives were designed, synthesized, and evaluated as Aurora A kinase inhibitors. The cell-based cytotoxicity assays showed that compound 16h was the most potent cytotoxic agent against all tested cancer cells and had a lower IC50 value than ENMD-2076 against MDA-MB-231 cells. Meanwhile, Aurora A kinase assay and Western blot analysis showed that 16h inhibited Aurora A kinase with an IC50 value of 21.94 nM and suppressed the phosphorylation of Histone H3 on Ser10 and Aurora A kinase on Thr288, which were consistent with the activation of Aurora A kinase. Accordingly, 16h caused aberrant mitotic phenotypes and obvious G2/M phase arrest in MDA-MB-231 cells and induced caspase-dependent apoptosis in MDA-MB-231 cells.
