Efficient Fmoc Group Removal Using Diluted 4-Methylpiperidine: An Alternative for a Less-Polluting SPPS-Fmoc/tBu Protocol

4-methylpiperidine is a toxic substance and is harmful to people and the environment. This reagent is commonly used for Fmoc group removal in SPPS-Fmoc/tBu, and this reaction is carried out using 4-methylpiperidine in DMF (20-25% v/v). We tested the efficiency of using diluted solutions of 4-methylpiperidine for SPPS-Fmoc/tBu. Fmoc removal was complete (> 99%) using 2.5% 4-methylpiperidine. The use of a diluted Fmoc removal reagent allowed us to synthesize peptides containing from 6 to 20 amino acid residues, with high purity and good yield. This process is less harmful for the environment and for humans, and furthermore it is less expensive.

Structure-based linker exploration: Discovery of 1-ethyl-1H-indole analogs as novel ATX inhibitors

Aiming to develop novel ATX inhibitors, an indole-3-carboxylic acid lead Indole-1 was identified through high-throughput screening (HTS) efforts. The Indole-1 analogs 1-7 was firstly prepared which exerted mild activity comparable to Indole-1 (740 nM) in ATX enzyme assay. Further structural modification to identify type IV ATX inhibitors was proceeded through derivatization of the indole-3-carboxylic acid group. Resultantly, compounds 8-17 containing acyl hydrazone linker displayed poor activity (over 3.49 mu M). Alternatively, replacing the acylhydrazone linker with urea counterpart by the amide bond reversal principle, the acquired compounds 18-22 achieved obvious improvements with submicromolar activities. Furthermore, with the aim to reducing cLogP, the thiazole ring of 18-22 was altered to the benzamide (23-32) with the urea linker unchanged. Remarkably, the benzamide derivative 24 with 4-hydroxy piperidine fragment was identified which exhibited prominent activity with IC50 value of 2.3 nM. Especially, dedicated molecular docking study was throughout the modification process which qualified 24 as optimal entity in accordance with the ATX inhibitory results.

Novel thermal radical initiators based on a triazene moiety for radical polymerization

In this study, we designed and synthesized novel thermal radical initiators of BTAP (1-phenyl-3,3-dipropyltriazene), BTACP (1-(phenyldiazenyl)pyrrolidine), BTACH (1-(phenyldiazenyl)piperidine), and BTACH7 (1-(phenyldiazenyl)azepane) based on a triazene moiety to provide a thermal initiator for radical polymerization. The synthetic method is valuable due to the simplicity. In addition, the synthesized thermal initiator did not affect the color of the polymer. Among the four initiators, the polymerization time for the BTACH of the 6-membered ring decreased by 67%, as opposed to the polymerization time without initiator. Conversion after polymerization was over 92%. DSC experiments also showed that the initiator with hexagonal rings had the lowest peak polymerization temperature of 160 degrees C. Our study suggests a promising new initiator system that is effective for radical polymerization. (C) 2018 The Korean Society of industrial and Engineering Chemistry. Published by Elsevier B.V.

Fractionation of Antimicrobial Compounds from Acacia nilotica Twig Extract Against Oral Pathogens

In the present study, the antimicrobial activity of fractions and sub-fractions of methanol extract of Acacia nilotica L. twig was done, and bioactive compounds were identified by GC-MS. Fractionation was done by column chromatography using different solvents, and their antimicrobial potential was checked by the agar well diffusion method. Minimum inhibitory concentration (MIC) was performed by the micro broth dilution method. Oral pathogens, including Enterococcus faecalis, Stophylococcus aureus, and Candida albicans were selected for the study. Results indicated that fraction (Fr-III) of A. nilotico methanol extract showed a significant zone of inhibition (ZOI) in the range of 14-15 mm against selected pathogens. Further sub-fraction, Fr-IIIf & Fr-IIIg of Fr-III exhibited maximum ZOI in a range of 38-40 mm at P<0.05. MIC of sample fractions was in the range of 80-210 mu g/mL. GC-MS analysis represented that Piperidine,2,2,6,6-tetramethyl-was the major phytochemical in Fr-III. In the case of Fr-IIIg, n-Hexadecanoic acid was the main component whereas behenic alcohol was in Fr-IIIf. Therefore. these bioactive compounds may be used as a potential therapeutic agent for oral health. Do you like my blog? If you like, you can also browse other articles about this kind.

Divergent approach to the synthesis of (-)-balanol heterocycle and cis-3-hydroxypipecolic acid based on chiral 2-aminoalkanol equivalent

Enantioselective synthesis of the hexahydroazepine core of (-)-balanol and formal synthesis of cis-3hydroxypipecolic acid from a common intermediate have been accomplished by a divergent path. The common intermediate was accessed from a favorably protected enantiomerically pure 2-amino-1,3,4-butanetriol (ABT) equivalent via oxidation and Wittig olefination. The synthesis of (-)-balanol heterocycle featured tandem reduction/acetal-deprotection/gamma-lactonization reaction and a one-pot azide reduction followed by seven membered aza-heterocycle formation while the route to cis-3-hydroxypipecolic acid highlighted the base induced piperidine ring formation and regioselective benzylidine-acetal cleavage.

Green synthesis of submicron-sized Ti-rich MWW zeolite powders via a novel mechanochemical dry gel conversion in mixed steam environment

In this research, a novel green mechanochemical dry gel conversion method (MDGC) is reported to obtain submicron-sized Ti-rich MWW zeolite. First, titanium and silica sources were milled under milder conditions in a planetary ball mill to construct the uniform SiO2-TiO2 composite powders with higher Ti contents. Subsequently, submicron-sized Ti-rich MWW zeolite powder was prepared via dry gel conversion (DGC) route using the obtained composite under mixed steam environment consisting of water and piperidine. The physicochemical properties of the SiO2-TiO2 composites before and after calcination and corresponding Ti-MWW-MDGC were investigated by XRD, UV-Vis, FT-IR, SEM, XRF, and N-2 absorption-desorption. Moreover, Ti-MWW (30)-MDGC exhibited a superior catalytic activity during epoxidation with H2O2 compared with the traditional DGC method, and the conversion of 1-hexene increased from 4.2% to 26.3%. The MDGC method is a promising approach for the green production of various zeolites with higher heteroatom contents, such as TS-1, Ti-Beta and Sn-MWW, etc. (C) 2020 The Society of Powder Technology Japan.

Multi-Stimuli Responsive Luminescent beta-Diketones and Difluoroboron Complexes with Heterocyclic Substituents

Emissive beta-diketones (bdks) and difluoroboron complexes (BF(2)bdks) exhibit multi-stimuli responsive luminescence, including solvatochromism, viscochromism, aggregation induced emission, thermal and mechanochromic luminescence, halochromism and pH sensing. In this study, a series of six-membered heterocycle-substituted (piperidine, morpholine, 1-methyl piperazine) bdk ligands and boron complexes were synthesized, and their luminescent properties were investigated. All the compounds exhibited red-shifted emission in more polar solvents due to intramolecular charge transfer as well as higher emission intensity in more viscous environments. In response to solubility changes in water/tetrahydrofuran mixtures, while the piperazine bdk ligand showed aggregation caused quenching, the piperidine and morpholine bdks displayed enhanced emission upon aggregation. In the solid state, all ligands exhibited mechanochromism. More dramatic halochromism was observed for the piperidine boron dye spin cast film. In solution, for the boron dyes under varying pH values (1-13), different protonated and deprotonated forms were analyzed according to the measured emission spectra.
