A transition-metal-free method for the alkylation of gem-diborylalkanes with alpha,beta-unsaturated ketones has been developed. It is demonstrated that the alpha-boryl radicals can be generated efficiently from gem-diborylalkanes with the aid of catechol and oxidants. The alpha-boryl radicals formed through such process can be engaged in conjugate addition reaction with alpha,beta-unsaturated ketones. This transformation is a straightforward method for the synthesis of gamma-borylketones.

Enteroviruses (EV) are a group of positive-strand RNA ( + RNA) viruses that include many important human pathogens (e.g. poliovirus, coxsackievirus, echovirus, numbered enteroviruses and rhinoviruses). Fluoxetine was identified in drug repurposing screens as potent inhibitor of enterovirus B and enterovirus D replication. In this paper we are reporting the synthesis and the antiviral effect of a series of fluoxetine analogues. The results obtained offer a preliminary insight into the structure-activity relationship of its chemical scaffold and confirm the importance of the chiral configuration. We identified a racemic fluoxetine analogue, 2b, which showed a similar antiviral activity compared to (S)-fluoxetine. Investigating the stereochemistry of 2b revealed that the Senantiomer exerts potent antiviral activity and increased the antiviral spectrum compared to the racemic mixture of 2b. In line with the observed antiviral effect, the Senantiomer displayed a dose-dependent shift in the melting temperature in thermal shift assays, indicative for direct binding to the recombinant 2C protein.

The tea geometrid Ectropis grisescens is an important pest of tea plant (Camellia sinensis (L.) O. Kuntze). It feeds on the new leaves and tender stems of tea plants, causing serious damage. The green leaf volatile (Z)-3-hexenol (z3HOL) can effectively activate the defense of tea against E. grisescens in the laboratory. In this study, z3HOL was confirmed to activate the tea mitogen-activated protein kinase and jasmonic acid (JA) burst in the laboratory. We investigated effects of z3HOL on the defense responses of tea plants under field conditions. Our results showed that tea plants exposed to z3HOL showed higher levels of JA and polyphenol oxidase (PPO) and emitted increased quantities of volatile organic compounds (VOCs) compared to non-exposed plants. Less E. grisescens larvae were observed in z3HOL-treated plots and less damage was found in z3HOL-treated plants than control. The number of Apanteles sp. and the parasitism of E. grisescens were also enhanced by z3HOL. These findings indicate that synthetic z3HOL can triggers tea defense responses against E. grisescens in the field, and that it could be used as a chemical elicitor to enhance biological control of tea geometrid in the future.

The synthesis of beta-hydroxy-alpha,alpha-difluorosulfona-mides was achieved by reacting difluoromethanesulfonamides with KHMDS in the presence of an aldehyde or ketone. The reaction exhibited a dramatic counterion effect with KHMDS or NaHMDS usually giving excellent yields in minutes, while lithium bases gave little or no product. Excellent yields and high diastereomeric ratios were achieved with N-alpha-benzyl-N-alpha-phenylfluorenyl (PhF)-protected chiral amino aldehydes derived from amino acids. Following deprotection, a beta-hydroxy-alpha,alpha-sulfonamide reacted under peptide coupling and Mitsunobu conditions to furnish a peptidomimetic in an excellent overall yield.

The alpha-lithiobenzyloxy group, easily generated from aryl benzyl ethers by selective alpha-lithiation with t-BuLi at low temperature, behaves as a directed metalation group (DMG) providing a direct access to o-lithiophenyl alpha-lithiobenzyl ethers. This ortho-directing effect is reinforced in substrates bearing an additional methoxy group at the meta position. The generated dianions can be reacted with a selection of electrophiles including carboxylic esters and dihalosilanes or germanes, which afford interesting benzofuran, sila(germa)dihydrobenzofuran, and silachroman derivatives from simple aryl benzyl ethers.

Due to hurdles, including resistance, adverse effects, and poor bioavailability, among others linked with existing therapies, there is an urgent unmet need to devise new, safe, and more effective treatment modalities for skin cancers. Herein, a series of flavonol-based derivatives of fisetin, a plant-based flavonoid identified as an antitumorigenic agent targeting the mammalian targets of rapamycin (mTOR)-regulated pathways, were synthesized and fully characterized. New potential inhibitors of receptor tyrosine kinases (c-KITs), cyclin-dependent kinase-2 (CDK2), and mTOR, representing attractive therapeutic targets for melanoma and non-melanoma skin cancers (NMSCs) treatment, were identified using inverse-docking, in vitro kinase activity and various cell-based anticancer screening assays. Eleven compounds exhibited significant inhibitory activities greater than the parent molecule against four human skin cancer cell lines, including melanoma (A375 and SK-Mel-28) and NMSCs (A431 and UWBCC1), with IC50 values ranging from 0.12 to < 15 mu M. Seven compounds were identified as potentially potent single, dual or multi-kinase c-KITs, CDK2, and mTOR kinase inhibitors after inverse-docking and screening against twelve known cancer targets, followed by kinase activity profiling. Moreover, the potent compound F20, and the multi-kinase F9 and F17 targeted compounds, markedly decreased scratch wound closure, colony formation, and heightened expression levels of key cancer-promoting pathway molecular targets c-Kit, CDK2, and mTOR. In addition, these compounds downregulated Bcl-2 levels and upregulated Bax and cleaved caspase-3/7/8 and PARP levels, thus inducing apoptosis of A375 and A431 cells in a dose-dependent manner. Overall, compounds F20, F9 and F17, were identified as promising c-Kit, CDK2 and mTOR inhibitors, worthy of further investigation as therapeutics, or as adjuvants to standard therapies for the control of melanoma and NMSCs.

The expected (E)-but-3-en-2-ones compounds I and II (half curcuminoids) were obtained by the Claisen-Schmidt reaction between aldehydes 3,4-dimethoxybenzaldehyde or 4-nitrobenzaldehyde with acetone. Concomitantly, 3-methylcyclohex-2-enones compounds III and IV arose from an unexpected reaction of but-3-en-2-ones in the cascade reaction of a Michael-type addition of a second molecule of acetone followed by Robinson annulation under strong basic conditions. Both enones exhibit the (E)-configuration, compound I displays s-trans conformation, whereas compound II exhibits conformational disorder as solid solution of s-cis and s-trans conformations. The related 3-methylcyclohex-2-enones exhibit envelope conformation. Compound III constitutes an example of the rarest case of racemic solid solution (pseudoracemate), where a lack of chiral discrimination with respect to the two enantiomers leads to an enantiomeric disorder of a racemic mixture with different occupancies at the reference site. Due to the lack of strong hydrogen-bond donors in all compounds, the crystal packing is mainly stabilized by weak intermolecular C-H center dot center dot center dot O interactions between the molecules. The present work provides a new perspective on the search for by-products normally overlooked in Claisen-Schmidt condensations.

In the present work, we report the design and fabrication of a copper-containing ionic liquid supported magnetic nanocatalyst via a convenient and straightforward synthetic approach for the formation of 2-phenylquinazolin-4(3H)-ones using o-aminobenzamide and benzaldehydes as the reaction partners. The successful formation and properties of the as-prepared catalyst have been thoroughly investigated using diverse physico-chemical techniques including FT-IR, XRD, FE-SEM, TEM, ICP, VSM, BET and TGA. Using this nanocatalytic system, a variety of 2-phenylquinazolin-4(3H)-ones are synthesized in excellent yields with operational ease and short reaction times in an environmentally preferable solvent under open air and without using any external oxidizing agent. Besides, the catalyst possessed facile magnetic recoverability and remarkable reusability for six consecutive runs without any appreciable decrease in the catalytic efficiency.

Quality Control of 4-Hydroxyquinolin-2(1H)-one. I found the field of Chemistry very interesting. Saw the article 4-Hydroxy-3-methyl-2(1H)-quinolone, originally discovered from a Brassicaceae plant, produced by a soil bacterium of the genus Burkholderia sp.: determination of a preferred tautomer and antioxidant activity published in 2020, Reprint Addresses Igarashi, Y (corresponding author), Toyama Prefectural Univ, Biotechnol Res Ctr, 5180 Kurokawa, Imizu, Toyama 9390398, Japan.; Igarashi, Y (corresponding author), Toyama Prefectural Univ, Dept Biotechnol, 5180 Kurokawa, Imizu, Toyama 9390398, Japan.. The CAS is 86-95-3. Through research, I have a further understanding and discovery of 4-Hydroxyquinolin-2(1H)-one.

4-Hydroxy-3-methyl-2(1H)-quinolone (1), a molecule known for a long time and recently discovered from a Brassicaceae plant Isatis tinctoria without providing sufficient evidence to support the structure, was isolated from a fermentation extract of Burkholderia sp. 3Y-MMP isolated from a soil by a Zn2+ enrichment culture. Detailed spectroscopic analyses by MS and NMR, combined with C-13 chemical shift comparison with literature values of the related compounds and a synthetic preparation of 1, allowed its first full NMR characterization and identification of 2-quinolone but not 2-quinolinol (2) as the preferred tautomer for this heterocyclic system. While the metal-chelating activity was negligible, compound 1 at 10 mu M, a concentration lower than that in liquid production cultures, quenched hydroxy radical-induced chemiluminescence emitted by luminol by 86%. Because some Burkholderia species are pathogenic to plants and animals, the above result suggests that 1 is a potential antioxidant to counteract reactive oxygen species-based immune response in the host organisms.

Insects use their olfactory systems to obtain chemical information on mating partners, oviposition sites and food. The yellow fever mosquito Aedes aegypti, an important vector of human infectious diseases, shows strong preference for human blood meals. This study investigated the chemical basis of host detection by characterizing the neuronal responses of antenna! olfactory sensilla of female Ae. aegypti to 103 compounds from human skin emanations. The effect of blood feeding on the responses of olfactory sensilla to these odorants was examined as well. Sensilla SBTII, GP, and three functional subtypes of SST (SST1, SST2, and SST3) responded to most of the compounds tested. Olfactory receptor neurons (ORNs) ‘A’ and ‘B’ in the trichoid sensilla, either activated or inhibited, were involved in the odour coding process. Compounds from different chemical classes elicited responses with different temporal structures and different response patterns across the olfactory sensilla. Except for their increased responses to several odorants, blood-fed mosquitoes generally evoked reduced responses to specific aldehydes, alcohols, aliphatics/aromatics, ketones, and amines through the SST1, SST2, SBTI, SBTII and GP sensilla. The odorants eliciting diminished responses in female mosquitoes after blood feeding may be important in Ae. aegypti host-seeking activity and thus can be candidates for mosquito attractants in the process of this disease vector management.
