Microwave-Assisted Synthesis of (Piperidin-1-yl)quinolin-3-yl)methylene)hydrazinecarbothioamides as Potent Inhibitors of Cholinesterases: A Biochemical and In Silico Approach

Alzheimer’s disease (AD), a progressive neurodegenerative disorder, characterized by central cognitive dysfunction, memory loss, and intellectual decline poses a major public health problem affecting millions of people around the globe. Despite several clinically approved drugs and development of anti-Alzheimer’s heterocyclic structural leads, the treatment of AD requires safer hybrid therapeutics with characteristic structural and biochemical properties. In this endeavor, we herein report a microwave-assisted synthesis of a library of quinoline thiosemicarbazones endowed with a piperidine moiety, achieved via the condensation of 6/8-methyl-2-(piperidin-1-yl)quinoline-3-carbaldehydes and (un)substituted thiosemicarbazides. The target N-heterocyclic products were isolated in excellent yields. The structures of all the synthesized compounds were fully established using readily available spectroscopic techniques (FTIR, H-1- and C-13-NMR). Anti-Alzheimer potential of the synthesized heterocyclic compounds was evaluated using acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes. The in vitro biochemical assay results revealed several compounds as potent inhibitors of both enzymes. Among them, five compounds exhibited IC50 values less than 20 mu M. N-(3-chlorophenyl)-2-((8-methyl-2-(piperidin-1-yl)quinolin-3-yl)methylene)hydrazine carbothioamide emerged as the most potent dual inhibitor of AChE and BChE with IC50 values of 9.68 and 11.59 mu M, respectively. Various informative structure-activity relationship (SAR) analyses were also concluded indicating the critical role of substitution pattern on the inhibitory efficacy of the tested derivatives. In vitro results were further validated through molecular docking analysis where interactive behavior of the potent inhibitors within the active pocket of enzymes was established. Quinoline thiosemicarbazones were also tested for their cytotoxicity using MTT assay against HepG2 cells. Among the 26 novel compounds, there were five cytotoxical and 18 showed proliferative properties.

A quinoline-based chromogenic and ratiometric fluorescent probe for selective detection of Mg2+ ion: Design, synthesis and its application in salt lake brines and bioimaging

A fluorescent probe was rational designed and prepared to distinguish Mg2+ ion from Ca2+ ion, in which 8-hydroxyquinoline acted as not only a fluorophore but also a recognition group. Notably, this probe QB (8-hydroxyquinoline-5-benzothiazole) shows two fluorescence response modes for highly selective detection of Mg2+ ion, namely fluorescence ratiometric mode and turn-on mode, which can be realized by controlling the excitation wavelength at 356 nm or 425 nm. After the addition of Mg2+ ion, the color of the QB solution changed from colorless to yellow, which can be easily found by naked eye. All experimental results suggested that probe QB has a high selectivity toward Mg2+ ion in the presence of other cations. Its detection limit for Mg2+ ion was estimated as low as 0.142 mu M, and this value was far lower than the intracellular concentration (0.5-1.2 mM). The detection mechanism was proposed further by the experiment of H-1 NMR titration and theoretical calculation. More significantly, this probe was successfully used to detect Mg2+ ion in brine samples as a quantitative method, and was also applied to detecting and imaging Mg2+ ion in living cells, indicating its great application value in practical use for the detection of Mg2+ ion.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 86-99-7, in my other articles.

Enhanced anaerobic degradation of quinoline and indole with dried Chlorella pyrenoidosa powder as co-metabolic substance

In coal gasification wastewater (CGW), nitrogen heterocyclic compounds (NHCs) are important refractory compounds. However, NHCs negatively impact human health and the environment due to its toxic, carcinogenic, and mutagenic properties. The main objective of this study was to determine the feasibility of Chlorella pyrenoidosa as a co-metabolite in enhancing anaerobic degradation of NHCs in CGW. So far, there have been few studies on enhanced anaerobic degradation with Chlorella pyrenoidosa as a cometabolic substance. It was speculated that Chlorella pyrenoidosa had certain feasibility in the enhanced degradation of NHCs. Anaerobic Reactor 1 was operated as a control, while Reactor 2 was operated with the addition of Chlorella pyrenoidosa. When the concentration of Chlorella pyrenoidosa was 100 mu g/L, Reactor 2 showed optimum degradation ratios on quinoline (100%) and indole (100%). Variations in the concentrations of Chlorella pyrenoidosa did not benefit the degradation efficiency of the reactor, whereby low dosages were not conducive for the microorganism’s growth and high dosages resulted in a competitive inhibition between the Chlorella powder and refractory compounds. In the effluent of Reactor 1, quinoline and indole concentrations were 12.79 +/- 1.21 and 18.45 +/- 1.11 mg/L, respectively. In Reactor 2, neither quinoline nor indole were detected. Acute bio-toxicity tests indicated a decrease in toxicity with the addition of Chlorella powder, hence reducing the inhibitions on seed germination and root elongation. The addition of Chlorella powder resulted in the increase of tryptophan protein and polysaccharide content in the extracellular polymeric substance of anaerobic sludge. In Reactor 2, bacterial community structures became more diverse and richer. Archaea communities became richer, but diversity declined. In the enhanced anaerobic degradation of NHCs, Chlorella pyrenoidosa powder was found to be an effective co-metabolite. (C) 2020 Published by Elsevier Ltd.

A Label-Free Cellular Proteomics Approach to Decipher the Antifungal Action of DiMIQ, a Potent Indolo[2,3-b]Quinoline Agent, against Candida albicans Biofilms

Candida albicans forms extremely drug-resistant biofilms, which present a serious threat to public health globally. Biofilm-based infections are difficult to treat due to the lack of efficient antifungal therapeutics, resulting in an urgent demand for the development of novel antibiofilm strategies. In this study, the antibiofilm activity of DiMIQ (5,11-dimethyl-5H-indolo[2,3-b]quinoline) was evaluated against C. albicans biofilms. DiMIQ is a synthetic derivative of indoquinoline alkaloid neocryptolepine isolated from a medicinal African plant, Cryptolepis sanguinolenta. Antifungal activity of DiMIQ was determined using the XTT assay, followed by cell wall and extracellular matrix profiling and cellular proteomes. Here, we demonstrated that DiMIQ inhibited C. albicans biofilm formation and altered fungal cell walls and the extracellular matrix. Cellular proteomics revealed inhibitory action against numerous translation-involved ribosomal proteins, enzymes involved in general energy producing processes and select amino acid metabolic pathways including alanine, aspartate, glutamate, valine, leucine and isoleucine. DiMIQ also stimulated pathways of cellular oxidation, metabolism of carbohydrates, amino acids (glycine, serine, threonine, arginine, phenylalanine, tyrosine, tryptophan) and nucleic acids (aminoacyl-tRNA biosynthesis, RNA transport, nucleotide metabolism). Our findings suggest that DiMIQ inhibits C. albicans biofilms by arresting translation and multidirectional pathway reshaping of cellular metabolism. Overall, this agent may provide a potent alternative to treating biofilm-associated Candida infections.

Efficient synthesis of novel 2-(2-chloroquinolin-3-yl)imidazo[1,2-a]pyridin-3-amine derivatives

An efficient method is applied for the synthesis of novel 2-(2-chloroquinolin-3-yl)-N-alkylimidazo[1,2-a]pyridin-3-amine derivatives. The method is based on a two-step approach from acetanilide, 2-chloro-3-formyl quinoline, 2-aminopyridine, and isocyanide under mild reaction conditions. In the first step, acetanilide forms 2-chloroquinoline-3-carbaldehyde in the presence of phosphoryl chloride. The synthesized 2-chloroquinoline-3-carbaldehyde takes part in a multicomponent reaction with 2-aminopyridine, and isocyanide in the presence of trimethylsilyl chloride. The reaction is facile and the products are synthesized in high isolated yields under mild reaction conditions.

Experimental and DFT studies on Hexacoordinated acyl(alkyl)and Pentacooordinated Hydroxyalkyl(phosphinite)erhodium(III). Catalytic Hydrolysis of Ammonia Borane

[Rh(nbd)Cl](2) (nbd=norbornadiene) reacts with quinoline-8-carbaldehyde (C9H6NCHO) and pyrazole (Hpz) affording, depending on Rh/Hpz ratio, acyl-alkyl [Rh(mu-Cl)(C9H6NCO)(Hpz)(sigma-C7H9)](2) (1) or [RhCl(C9H6NCO)(Hpz)(2)(sigma-norbornenyl)] (2), stereoselectively as confirmed by DFT calculations. Hydrogen bond between NH-pyrazole and O-acyl occurs. 1 and 2 react with diphenylphosphine oxide (SPO) giving 16e [RhCl(C9H6NC(nbyl))(Ph2PO)(Hpz)] (3) through SPO kappa(1)-P-coordination, C-C bond coupling between acyl and norbornenyl and outer-sphere O(P)-to-O(C) hydrogen transfer. 3 shows distorted trigonal bipyramidal structure with weak intramolecular (C)-OH…O(=P) and NH…Cl hydrogen bonds. DFT calculations indicate this 16e structure being favoured by sigma- and pi-type orbital multi-overlapping between pyrazole and both the OH…O and chlorine and by intermolecular forces in the crystal. Solutions of 3 contain an equilibrium between trigonal bipyramid and a square-planar pyramid with OH interacting with phosphoryl and NH, confirmed by DFT C-13 NMR calculations. 1 is very efficient homogeneous catalyst for H3N-BH3 hydrolysis to release hydrogen under air.
