Synthesis of chiral nonracemic 1-(2-pyridinyl)ethylamines: Stereospecific introduction of amino function onto the 2-pyridinylmethyl carbon center

Stereospecific substitutions of optically pure 1-(pyridinyl)ethyl methanesulfonates with various amines are described. The reaction of (R)- or (S)-1-(2-pyridinyl)ethyl methanesulfonate with primary amines, including amino acid esters, gives N-substituted (S)- or (R)-1-(2-pyridinyl)ethylamines (4) with inversion of the configuration. Secondary cyclic amines are also reacted with (R)-2 to give the corresponding substituted amines (5) in excellent yields. Optically pure and meso triamine ligands having two pyridine rings, (S,S)-4f and meso-4f, (S,S)-9e, (S,R)-9e, and (S,S)-9f, have been prepared in stereochemically pure form by this method. Not only the substitution reaction of optically active 2 but also that of 1-(4-pyridinyl)ethyl and 1-(3-pyridinyl)ethyl methanesulfonates 11 and 14 take place stereospecifcally with inversion of the chiral center.

Improved 2,4-diarylthiazole-based antiprion agents: Switching the sense of the Amide Group at C5 leads to an increase in potency

Amide derivatives of 2,4-diarylthiazole-5-carboxylic acids were synthesised and tested for efficacy in a cell line model of prion disease. A number of compounds demonstrating antiprion activity were thereby identified from the screening libraries, showing improved potency and reproducibility of results relative to amide derivatives of the related 2,4-diphenyl-5-aminothiazole, which have been documented previously. Thus, ‘switching’ the sense of the amide bond at thiazole C5 revealed a more promising lead series of potential prion disease therapeutics. Furthermore, 3,5-diaryl-1,2,4-thiadiazoles isolated as by-products during library synthesis provided a handful of additional examples possessing an antiprion effect, thereby augmenting the set of newly identified active compounds. Evaluation of binding to cellular prion protein (PrPC) showed only weak affinities at best, suggesting that the newly identified antiprion agents do not mediate their biological effect through direct interaction with PrPC.

Functionalised heterogeneous catalysts for sustainable biomass valorisation

Efficient transformation of biomass to value-added chemicals and high-energy density fuels is pivotal for a more sustainable economy and carbon-neutral society. In this framework, developing potential cascade chemical processes using functionalised heterogeneous catalysts is essential because of their versatile roles towards viable biomass valorisation. Advances in materials science and catalysis have provided several innovative strategies for the design of new appealing catalytic materials with well-defined structures and special characteristics. Promising catalytic materials that have paved the way for exciting scientific breakthroughs in biomass upgrading are carbon materials, metal-organic frameworks, solid phase ionic liquids, and magnetic iron oxides. These fascinating catalysts offer unique possibilities to accommodate adequate amounts of acid-base and redox functional species, hence enabling various biomass conversion reactions in a one-pot way. This review therefore aims to provide a comprehensive account of the most significant advances in the development of functionalised heterogeneous catalysts for efficient biomass upgrading. In addition, this review highlights important progress ensued in tailoring the immobilisation of desirable functional groups on particular sites of the above-listed materials, while critically discussing the role of consequent properties on cascade reactions as well as on other vital processes within the bio-refinery. Current challenges and future opportunities towards a rational design of novel functionalised heterogeneous catalysts for sustainable biomass valorisation are also emphasized.

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.Quality Control of (cis-Tetrahydrofuran-2,5-diyl)dimethanol, you can also check out more blogs about2144-40-3

Design, synthesis, antiproliferative activity and docking studies of quinazoline derivatives bearing 2,3-dihydro-indole or 1,2,3,4-tetrahydroquinoline as potential EGFR inhibitors

Eight series of quinazoline derivatives bearing 2,3-dihydro-indole or 1,2,3,4-tetrahydroquinoline were designed, synthesized and evaluated for the IC50 values against three cancer cell lines (A549, MCF-7 and PC-3). Most of the forty nine target compounds showed excellent antiproliferative activity against one or several cancer cell lines. The compound 13a showed the best activity against A549, MCF-7 and PC-3 cancer cell lines, with the IC50 values of 1.09 ¡À 0.04 muM, 1.34 ¡À 0.13 muM and 1.23 ¡À 0.09 muM, respectively. Eight selected compounds were further selected to evaluated for the inhibitory activity against EGFR kinase. Three of them showed equal activity against EGFR kinase to positive control afatinib. AnnexinV-FITC, propidium iodide (PI) double staining and acridine orange single staining results indicated that the compound 13a could induce apoptosis of human lung cancer A549 cells.
