Acid and Solvent Effects on the Regioselectivity of Minisci-Type Addition to Quinolines Using Amino Acid Derived Redox Active Esters

Minisci-type reactions comprise an important class of reactions for the direct functionalization of basic heterocyclic compounds. On certain heterocycles, such as quinolines, Minisci-type reactions face a regioselectivity choice which often results in mixtures of regioisomers at the C2 and C4 positions, limiting utility. We present a study of the effect of solvent and Bronsted acid catalyst on regioselectivity in the addition of N -acetyl-substituted, alpha-amino alkyl radicals to quinolines. By tuning the solvent and acid combination we identify conditions that strongly favour C2 and strongly favour C4 and present a small scope of compatible substrates.

Bio-Fe3O4-MNPs Promoted Green Synthesis of Pyrido[2,1-a]isoquinolines and Pyrido[1,2-a]quinolines: Study of Antioxidant and Antimicrobial Activity

In this work, synthesis of pyrido[2,1-a]isoquinolines and pyrido[1,2-a]quinolines in excellent yield using multicomponent reactions of isoquinoline, methyl malonyl chloride, alkyl bromides, and triphenylphosphine in the presence of catalytic amount of Fe3O4-MNPs in water at 80 degrees C were investigated. The reduction of ferric chloride solution with Clover Leaf water extract caused to synthesis of magnetic iron oxide nanoparticles (Fe3O4-NPs) as a green method. As well, antioxidant activity was studied for some newly synthesized compounds such as 6a, 6b, 8b, and 8c using the DPPH radical trapping and reducing of ferric ion experiments and comparing results with synthetic antioxidants (TBHQ and BHT). As a result, compounds 6a, 6b, 8b, and 8c show trace DPPH radical trapping and excellent reducing strength of ferric ion. These compounds have biological potential because of isoquinoline or quinoline core. For this reason, the antimicrobial activity of some synthesized compounds was studied employing the disk diffusion test on Gram-positive bacteria and Gram-negative bacteria. The results of disk diffusion test showed that compound 6a, 6c, 6d, 8a, and 8b prevented the bacterial growth.

Respiration Responses of Earthworm to Soil Amended with Phenanthrene and the Nitrogen Heterocyclic Analogues

A disturbance in the normal physiology of soil macroinvertebrates can cause toxic impacts and/or disruption in mechanisms and rates of respiration. In this work, respiration rates of earthworms exposed to phenanthrene and its nitrogen heterocyclic analogs was investigated over a 30 and 90-d soil-contact-time. The study involved measurement and calculation of CO2 production by earthworms exposed to phenanthrene-N-PAHs amended soils. Data showed that N-PAH chemicals mostly affected the respiration rates of the earthworms compared to the homologous-PAH analog over time. The concentration-time plots showed greater respiration with increase in concentration over time. Calculated respiration inhibition-effect (%) revealed that phenanthrene had low degree of inhibition (27%) in the first 30-d at the highest concentration, while, NPAHs exhibited high degree of inhibitions (>45%) on respiration/physiological function of the exposed earthworms over the 90-d contact-time. Among the N-PAH chemicals, benzo[h]quinoline recorded >25% inhibition even at the lowest concentration (30-d). Statistical analysis of data revealed that N-PAHs maintained strong positive correlation on respiration response of the organisms with increased concentration and time (R-2 = 0.803-0.997, p < .05). This suggests that N-PAH chemicals may have caused severe metabolic and physiological stress/inhibitions to soil organisms. Furthermore, the use of earthworm's respiration rate in polluted soils could likely reshape the understanding of environmental stressors and serve as an early warning indicator for potential ecosystem shifts. But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 857890-39-2, you can contact me at any time and look forward to more communication.

Design and development of Tetrahydro-Quinoline derivatives as dual mTOR-C1/C2 inhibitors for the treatment of lung cancer

Lung cancer is one of the most prevailed cancer worldwide. Many genes get mutated in lung cancer but the involvement of EGFR, KRAS, PTEN and PIK3CA are more common. Unavailability of potent drugs and resistance to the available drugs are major concern in the treatment of lung cancer. In the present research, mTOR was selected as an important alternative target for the treatment of lung cancer which involves the PI3K/AKT/mTOR pathway. We studied binding interactions of AZD-2014 with the mTOR protein to identify important interactions required to design potent mTOR inhibitors which was supported by QSAR studies. Pharmacophore based virtual screening studies provided core scaffold, THQ. Based on molecular docking interactions, 31 THQ derivatives were synthesized and characterized. All compounds were screened for cellular mTOR enzyme assay along with antiproliferative activity against the panel of cancerous cell lines, from which 6 compounds were further screened for colony forming assay. Two most potent compounds, HB-UC-1 and HB-UC-5, were further screened for flow cytometry analysis, gene expression study and western blot analysis. Gene expression study revealed the efficiency of compound HB-UC-1 against both mTORC1 and mTORC2 by affecting downstream regulators of mTORC1 (E4BP4, eIF4EBP1) and mTORC2 (PCK1), respectively. In western blot analysis, both compounds, inhibited phosphorylation of AKT 5473 which proved the efficiency these compounds against the mTORC2. These two compounds were further screened for in-vivo biological evaluation. Both compounds increased lifespan of cancer-bearing animals with improvement in mean survival time. Further, in bezopyrene induced lung cancer animal model, both compounds showed effectiveness through the biochemical parameters and histopathological evaluation of the lung tissue. In future, potent hit compound from this series could be modified to develop lead mTOR inhibitors for the treatment of lung cancer.

Phosphoric Acid Mediated Light-Induced Minisci C-H Alkylation of N-Heteroarenes

Herein, we report an environmentally-friendly light-induced Minisci alkylation of N-heteroarenes with a broad substrate scope using diphenyl phosphate as catalyst under metal- and photocatalyst-free conditions. The radical precursor redox-active esters (RAEs) were introduced as alkylating reagents for the functionalization of N-heteroarene derivatives including pyridine, quinoline, and isoquinoline. Mechanistic studies suggested that diphenyl phosphate played a key role via hydrogen bonding in the catalytic cycle.

Synthesis, Antimicrobial Capability and Molecular Docking of Heterocyclic Scaffolds Clubbed by 2-Azetidinone, Thiazole and Quinoline Derivatives

A new set of molecules was designed and synthesized by compilation of pharmacologically potential segments thiazole and quinoline bridged by 2-azetidinone as a linker in a single molecular skeleton. Structural analysis of synthesized molecules (5a-p) was executed by IR, H-1 NMR, C-13 NMR, and mass spectroscopy techniques. Aforesaid compounds were analyzed for investigation of their antimicrobial capability against several bacterial and fungal strains. The synthesized compounds 5b, 5f, 5h, 5i, 5k, and 5l were active against bacterial strains while compounds 5j and 5k were active against fungal strains. Synthesized compounds were found to be potential inhibitors against gram-negative bacterial strains Escherichia coli and Pseudomonas aeruginosa, while the same were not effective against gram-positive strains of Staphylococcus aureus and Streptococcus pyogenes. Compounds with electron-releasing substituents were active molecules against all fungal strains used in screening. Also, the influence of substituents on the antimicrobial activity of target molecules (5a-p) was discussed. Molecular docking study against crucial microbial target beta-Ketoacyl-acyl carrier protein (ACP) synthase III (FabH) could provide valuable insights into their plausible mechanism of action.

N,N-Dialkylhydrazones as Versatile Umpolung Reagents in Enantioselective Anion-Binding Catalysis

An enantioselective anion-binding organocatalytic approach with versatile N,N-dialkylhydrazones (DAHs) as polarity-reversed (umpolung) nucleophiles is presented. For the application of this concept, a highly ordered hydrogen-bond (HB) network between a carefully selected CF3-substituted triazole-based multidentate HB-donor catalyst, the ionic substrate and the hydrazone in a supramolecular chiral ion-pair complex was envisioned. The formation of such a network was further supported by both experimental and computational studies, which showed the crucial role of the anion as a template unit. The asymmetric Reissert-type reaction of quinolines as a model test reaction chemoselectively delivered highly enantiomerically enriched hydrazones (up 95:5 e.r.) that could be further derivatized to value-added compounds with up to three stereocenters.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 857890-39-2. Recommanded Product: Lenvatinib Mesylate.

Asymmetric Synthesis of alpha-Alkylated gamma-Lactam via Nickel/8-Quinim-Catalyzed Reductive Alkyl-Carbamoylation of Unactivated Alkene

Chiral-auxiliary-mediated synthesis represents the most frequently used synthetic tool for the induction of chirality on alpha-position of gamma-lactams in organic synthesis. However, the general strategy requires the stoichiometric use of chiral reagents with multiple manipulation steps. Transition-metal-catalyzed asymmetric alkene dicarbofunctionalization using readily available substrates under mild conditions allows the simultaneous construction of two vicinal chemical bonds and a chiral carbon center, hence, gain expedient access to chiral heterocycles. Herein, we disclose a Ni-catalyzed enantioselective reaction of 3-butenyl carbamoyl chloride and primary alkyl iodide enabled by a newly designed chiral 8-quinoline imidazoline ligand (8-Quinim). This protocol features broad functional group tolerance and high enantioselectivities, achieving unprecedented synthesis of chiral nonaromatic heterocycles via catalytic reductive protocol.
