Recent trends in microencapsulation for smart and active innovative textile products

The industrial interest for microencapsulation techniques to produce innovative materials has increased in the last years. Microencapsulation shows several advantages for textile industries since active compounds, such as vitamins, essential oils, antimicrobials and/or antibiotics can be isolated to protect them from environment factors (oxygen, light, moisture and temperature). Microcapsules are also used for the controlled release of fragrances or even heat, to mask undesired properties of the active components and to convert liquid substances into solids with increased compatibility. In this review, the application of microencapsulation techniques to obtain innovative materials for the textile sector has been highlighted. The main known techniques have been briefly described, including interfacial, suspension and in situ polymerizations as well as spray drying, complex coac-ervation, centrifugal extrusion processes, fluidized-bed-coating and sol-gel techniques. Different mechanisms have been also described based on the different properties offered by permeable or non-permeable capsules. Finally, the development and application of microencapsulation in smart (phase change materials, photochromic, thermochromic and flame retardant microcapsules) and active textiles, including antimicrobials and the use of different additives with pharmaceutical and/or medical properties, insect-repellent systems and fragrant solid carrier materials have been briefly discussed.

Synthesis of imidazopyridine-fused indoles via one-pot sequential Knoevenagel condensation and cross dehydrogenative coupling

A simple and efficient strategy for the synthesis of imidazopyridine-fused indoles has been developed that involves one-pot sequential Knoevenagel condensation of readily available active methylene azoles with N-substituted-1H-indole-3-carboxaldehydes or N-substituted-1H-indole-2-carboxaldehydes followed by palladium-catalyzed intramolecular cross dehydrogenative coupling reaction. A series of 36 derivatives was prepared by using this strategy. The products were obtained in moderate to excellent (32-94%) yields and showed broad substrate scope with tolerance of various functional groups and was amiable for gram scale preparation without problems.

A combined experimental and DFT computations study of novel (E)-3-(benzofuran-2-yl)-2-(thiophen-2-yl)acrylonitrile(TACNBNF): Insight into the synthesis, single crystal XRD, NMR, vibrational spectral analysis, in vitro antioxidant and in silico molecular docking investigation with human peroxiredoxin 5 protein

The synthesized (E)-3-(benzofuran-2-yl)-2-(thiophen-2-yl)acrylonitrile (TACNBNF) crystal compound was characterized using FT-IR, 1H and 13C NMR analyses, ESI-mass and photoluminescence studies. Single crystal X-ray diffraction investigations reveal that the molecule is associated with the C (7)?H (7) ? S (1) donor-acceptor hydrogen bond interaction. The bond angle at C7 gives a strong indication that H7?S1 contact is repulsive. However, the C5?C7?C8 bond angle = 128.8 (2) , is distorted due to strain induced by double bond linkage at C5=C7. The computational work such as optimized geometry by Density functional theory (DFT), FT-IR, Molecular electrostatic potential (MEP), Frontier Molecular orbitals (FMOs), Mulliken’s population analysis, Nonlinear optical effects (NLO), and Natural bond orbitals (NBO) were analyzed with the aid of Gaussian 03 program using basic set B3LYP/6?311++G (d,p). The proton 1H and carbon 13C NMR chemical shifts of molecules were simulated by the gauge-independent atomic orbital (GIAO) manner and also compared with experimental 1H and 13C NMR results. The in vitro antioxidant study was carried out in DPPH assay ascorbic acid, a standard drug. The in silico molecular docking, ADMET and toxicity studies were performed by Discovery Studio 4.0.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 4265-16-1, help many people in the next few years.Recommanded Product: 4265-16-1

Design, synthesis and antiproliferative activity against human cancer cell lines of novel benzo-, benzofuro-, azolo- and thieno-1,3-thiazinone resorcinol hybrids

In this paper we report the design and synthesis of novel derivatives of the 4H-3,1-benzothiazinone type and heterocyclic analogues, i.e. benzofuro-, azolo- and thieno-1,3-thiazin-4-ones possessing 2,4-dihydroxyphenyl substituent. The compounds were obtained by the one-step reaction of aminobenzamides or heterocyclic aminocarboxamides with aryl-modified sulfinylbis[(2,4-dihydroxyphenyl)methanethione]. Evaluation of their antiproliferative potency against human cancer cell lines showed that the activity of some analogues was similar to that of cisplatin. The highest activity and low toxicity were found for 6-tert-butyl-2-(5-chloro-2,4-dihydroxyphenyl)-4H-thieno[3,2-d][1,3]thiazin-4-one. The structure?activity elucidation reveals that the most active compounds are those with a thienothiazin-4-one and benzofuro[3,2-d][1,3]thiazin-4-one skeleton and the presence of the hydrophobic substituent (Et, Cl) in the benzenediol moiety increases their antiproliferative potency. The ADMET properties of selected compounds including metabolic stability and toxicity profile were estimated in silico.

Implications of promiscuous Pim-1 kinase fragment inhibitor hydrophobic interactions for fragment-based drug design

We have studied the subtleties of fragment docking and binding using data generated in a Pim-1 kinase inhibitor program. Crystallographic and docking data analyses have been undertaken using inhibitor complexes derived from an in-house surface plasmon resonance (SPR) fragment screen, a virtual needle screen, and a de novo designed fragment inhibitor hybrid. These investigations highlight that fragments that do not fill their binding pocket can exhibit promiscuous hydrophobic interactions due to the lack of steric constraints imposed on them by the boundaries of said pocket. As a result, docking modes that disagree with an observed crystal structure but maintain key crystallographically observed hydrogen bonds still have potential value in ligand design and optimization. This observation runs counter to the lore in fragment-based drug design that all fragment elaboration must be based on the parent crystal structure alone.

Novel phthalamides containing sulfiliminyl moieties and derivatives as potential ryanodine receptor modulators

To tackle the serious challenge of insect resistance and stricter environmental regulations, innovating a new eco-friendly insecticide is urgently required. A series of new phthalamides containing sulfiliminyl and sulfoximinyl moieties were designed and synthesized. In total, 30 new structures were characterized by 1H NMR spectra and HRMS. The bioassay results indicated that some title compounds exhibited excellent insecticidal activities against oriental armyworm (Pseudaletia separata Walker) and diamondback moth (Plutella xylostella (L.)). 4a showed the same larvicidal level as that of commercial flubendiamide as a control. 7a and 9a exhibited outstanding activity against diamondback moth. The LC50 values of 7a and 9a were 8.33 ¡Á 10-8 and 2.34 ¡Á 10-8 mg L-1, respectively, lower than that of flubendiamide (1.25 ¡Á 10-7 mg L-1). The effects of 4a, 7a and 9a on intracellular calcium of neurons from the beet armyworm (Spodoptera exigua) indicated that these title compounds activate the receptor-operated calcium channel. The calcium ions efflux from the calcium store on endoplasmic reticulum (ER) when treated with novel compounds. The results of CoMFA calculation showed that N-cyanosulfilimines and N-trifluoroacetylsulfoximines might be of importance to the larvicidal activity. The present work demonstrated that structures containing sulfiliminyl and sulfoximinyl moieties can be considered as lead compounds for the development of new insect ryanodine receptor modulators.

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.Application In Synthesis of 4-Fluoroisobenzofuran-1,3-dione, you can also check out more blogs about652-39-1

A simple synthesis of nitriles from aldoximes

Easily synthesized aldoximes have been converted to the corresponding nitriles under very mild conditions by a simple reaction with lH-benzotriazol-l-yloxytris(dimethylamino)phosphonium hexafluorophosphate (BOP) and DBU in CH2CI2, THF, or DMF. As an alternative reagent that eliminates the formation of hexamethylphosphoramide as a byproduct, use of lH-benzotriazol-lyl-4-methylbenzenesulfonate (Bt-OTs) and DBU was investigated. Reactions with this reagent also proceeded smoothly and in good yields, although in one case N-sulfonylation was observed. An attempt to gain mechanistic insight into the BOP-mediated reaction has been made using 31P{ 1H} NMR. However, no phosphorus-bearing intermediate could be readily observed. Finally, the method has been applied to the synthesis of an antiviral 4′-cyano adenosine analogue from a commercial precursor using a single saccharide protecting group.

Simultaneous biodegradation of mixture of carbamates by newly isolated Ascochyta sp. CBS 237.37

In this study, a mixture of carbamates (CRBs) degrading Carb.1b strain was isolated from soil. Based on the morphology and 18S rRNA sequence analysis, the strain was identified as an Ascochyta sp. CBS 237.37 with accession number MG786925. The isolate was employed in two growth mediums (added carbon and carbon-free) enriched with varied concentrations of CRBs ranging from 25 to 85 mg L?1 to assess its degradation efficacy. As determined by the Response Surface Methodology (RSM), optimum parameters for the degradation were: pH value of 7.5 and temperature of 28 C. The degradation was inhibited at higher concentrations and was found to be 91.2%/94.8%, 67.25%/71.75%, 55.81%/59.81%, 46.85%/49.57% and 36%/40.80% (in carbon-free/added carbon) after 20 d. The removal of the higher concentration CRBs was comparatively slower, and the obtained degradation rate constant (Kavg) 0.03412 d?1. Added carbon and carbon-free medium removed over 86.7%/90.15% of CRBs (85 mgL?1) with the half-life (t1/2) of 26 d and R2 ranging from 0.982 to 0.999; indicating the high tolerance of carb.1b strain towards CRBs. Residual analysis of CRBs biodegradation was performed using GC/MS analysis. This is the first report of degradation of a mixture of CRBs by Ascochyta sp. CBS 237.37. The results of this study can possibly impact the development strategies of bioremediation for the elimination of CRBs.
