Incorporation of poly(ethylene glycol) 4000 and poly(ethylene glycol) 4000 distearate into tapioca starch influences the pattern of its thermal degradation. Involvement of free radicals generated by poly(ethylene glycol) decomposition is suggested as a plausible mechanism for the enhancement of ...

The Li+ diffusion and phase behavior of the lithium-doped poly(ethylene glycol) distearate were studied by 7Li NMR, DSC, and polarized-light optical microscopy. The spectra for highly Li+-doped samples (oxygen-to-lithium ratio y≤9) show 7Li quadrupolar powder patterns even at temperatures above...

Novel lamellar-mesostructured poly(ethylene glycol) distearate (PEGDS)/silica hybrids have been synthesized successfully through self-assembly with a sol–gel technology, in which the PEGDS is imbedded within silica interlayers through a micelle-templating technique by seeding rod micelles of th...

A lamellar-mesostructured silica has been synthesized by using poly(ethylene glycol) distearate as template in ethanol solution. Highly ordered lamellar mesostructure was confirmed by X-ray diffraction pattern, transmission electronic microscopy, and nitrogen adsorption–desorption isotherm. The...

Ethylene glycol distearate (EGDS) was forced to crystallize as thin platelet in order to obtain a pearlescent effect. This was possible by performing a cooling surface crystallization in oil-in-water emulsion with the presence of an emulsifier. Under stagnant conditions, nucleation events and gr...

A series of novel multipolar symmetric and asymmetric N–heterocyclic compounds with different configurations were designed and synthesized. Their structures were characterized by Fourier transform infrared spectroscopy, hydrogen−1 nuclear magnetic resonance, and mass spectrometry. Their photoph...

A series of simplified berberine analogs was designed, synthesized, and evaluated for anti-inflammatory activity. SAR studies identified N-benzyltetrahydroisoquinoline 7d as a potent berberine analog. 7d suppressed LPS-induced inflammatory cytokine levels in both BV2 cells and primary microglia....

Direct synthesis of the pyrrolophenanthridone scaffold was explored using an intramolecular Pd(II)-mediated coupling reaction of different N-acylindolines via CH activation. Amaryllidaceae alkaloids of the lycorine type belong to this type. Depending on the substitution pattern of the starting m...

3H-1,3,4-Oxadiazole-2-thione and 3H-1,3,4-oxadiazol-2-one derivatives were synthesized and tested for their in vitro antimycobacterial activity. Oxadiazolone derivatives showed an interesting antimycobacterial activity against the tested strain of Mycobacterium tuberculosis H37Rv, whereas the co...

In this study, new Schiff bases and β-lactam derivatives containing morpholine and thio morpholine nuclei were synthesized. Antimicrobial, antioxidant, antimicrobial and antioxidant properties of all synthesized compounds were investigated and highly effective products were obtained. In this co...

We have made an effort to synthesize ternary complexes [Cu2(L)2(Him)2]·CH3OH 1, [Cu(L)(bipy)] 2 and [Ni(HL)(PMDT)]BF4 3 (H2L = N′-(1E)-[(5-bromo-2-hydroxyphenyl)methylidene]benzoylhydrazone; Him = imidazole; bipy = 2,2′-bipyridine and PMDT = N,N,N′,N″,N″-pentamethyldiethylenetriamine). The...

In recent years, the imine-bridged organics has been one of the hot spots in the field of photo-responsive materials. Herein, N-(5-chloro-2-hydroxyphenyl)-(3-bromo-6-oxocyclohexa-2,4-dienylidene)-methylamine (CHPBOCDMA) was synthesized and characterized by a combined experimental and theoretical...

A new Schiff base ligand (ONO), 4-Bromo-2-(((5-chloro-2-hydroxyphenyl)imino)methyl)phenol and its vanadium(V) complexes [VO(L)(MeO)(MeOH)] 1, [VO(L)(EtO)]2 2, [VO(L)(2-BuO)] 3, were prepared and characterized by elemental analyses, FT-IR, UV–Vis, 1H NMR and TGA techniques. The structures of the...

Highly efficient poly functionalized pyrrolo[3,2-a]carbazoles via ring contraction through rearrangement and intramolecular Michael addition reaction using one pot multicomponent reaction (MCR) is reported for the first time. Free radical scavenging and anticancer activities were determined by D...

2-Amino-3,5-dibromoacetophenone undergoes Vilsmeier reaction with a phosphoryl chloride–dimethylformamide mixture to afford 6,8-dibromo-4-chloroquinoline-3-carbaldehyde. The latter was reacted with arylhydrazine hydrochlorides in ethanol in the presence of triethylamine to afford the correspond...

Vinylmercury compounds, vinylboronic acids and vinylstannanes undergo rapid metal-lead exchange with lead tetraacetate in deuterochloroform to generate vinyllead triacetates, which have been characterised by their 1H1H and 207Pb1H coupling constants. In addition, a number of divinyl and mixe...
