A novel fluorescence switch sensor was constructed for detecting the fungicide fenaminosulf (FM), based on a dye-doped molecularly imprinted polymer (MIP) and silver nanofilm amplification. The MIP was prepared by electropolymerization of hydroquinone doped with neutral red on the silver nanofil...
The reaction of [60]fullerene (C 60 ) with nitrile ylides generated from N-benzyl-4-nitrobenzimidoyl chloride/N-(4-chlorobenzyl)-4-nitrobenzimidoyl chloride and triethylamine gave only isomeric monoadducts of C 60 with [6,6]-closed structure. No [5,6]-open adduct of C 60 ...
Aldol type condensation of enantiomerically pure t-butyl p-tolyl sulfinyl acetate was shown to give the opposite configuration at the hydroxylic center in the case of an α,β-unsaturated aldehyde, a result which is in sharp contrast with literature results. The absolute configurations of the al...
Addition reaction of 1-chlorovinyl p-tolyl sulfoxides, which were derived from various aldehydes, with lithium enolate of tert-butyl acetate at −78°C in THF gave adducts in high yields. Magnesium carbenoids were generated by treatment of these adducts with Grignard reagents via the sulfoxide–m...
1-[2-(p-Tolyl)-1-diazenyl]-3-({3-[2-(p-tolyl)-1-diazenyl]perhydrobenzo[d]imidazol-1-yl}methyl)perhydrobenzo[d]imidazole(1) has been synthesized by reactionof a mixture of 1,2-diaminocyclohexane and formaldehyde withp-toluene diazonium chloride inaqueous solution. The product has been characteriz...
In previous reports, our laboratory has described a drug-responsive NADH oxidase activity of the external surface of the plasma membrane of HeLa and other cancer cells, but not from normal cells, that was shed into media conditioned by the growth of cancer cells such as HeLa and also into sera o...
A one-dimensional (1-D) selenidostannate, [AEPPH2]2[Sn5Se12] (AEPP=N-aminoethylpiperazine) (1), has been prepared under solvothermal condition and characterized. Single crystal X-ray analysis reveals that compound 1 crystallizes in the triclinic space group P-1, a=10.6351(7) Å, b=10.6850(7) Å, c...
A new organic-inorganic hybrid material, 1-amonioethylpiperazine-1, 4-diium tetrachloridozincate(II) chloride, (C6H18N3)[ZnCl4]Cl, has been synthesized and characterized by various physicochemical techniques including UV–visible absorption, Infra-Red (IR), Raman and NMR spectroscopies. The comp...
Lipolase 100 L, the lipase from the genetically engineered species of Aspergillus oryzae, has been used to catalyze esterification of lauric acid with aromatic alcohol-benzyl alcohol. A kinetic model for the lipase-catalyzed esterification in a biphasic organic-aqueous system has been proposed. ...
Dietary polyphenols have been reported as an effective phytochemical for health protection and cinnamic acid (CA) is one of the polyphenols that has been demonstrated having chemopreventive potential. It was known that the early and distal metastasis might lead to the high mortality of patients ...
The objective of this study was to formulate a self‐nanoemulsifying oral drug delivery system (SNEDDS) for the poorly water‐soluble trans‐Cinnamic acid (t‐CA SNEDDS) that could be evaluated for its antihyperglycemic efficacy in comparison to the parent t‐CA in an alloxan‐induced diabetic r...
BACKGROUND Trans‐cinnamic acid (t‐CA) and its derivatives have been shown to be antioxidant and antibacterial, and can be used in food additives and flavors. However, a traditional t‐CA production via chemical synthesis with a condensation reaction may not be suitable for its application in t...
The crystal structure of the product [Cu(H 3 L)ClO 4 ] 2 synthesized from an aqueous solution of L=N,N,N',N'-tetrakis(2-hydroxyethyl)ethylenediamine (THEEN, C 1 0 H 4 N 2 O 4 ) and an alkaline aqueous solution of (CuClO 4 ) ...
A new water soluble palladium(II) complex (2) derived from N,N,N′,N′-tetrakis(2-hydroxyethyl)ethylenediamine (edteH 4 ) (1) was synthesized in high yield and characterized by 1 H, 13 C, HMQC and COSY NMR spectroscopy. X-ray diffraction studies on a single crystal of 2 c...
To determine 3-amino-5-morpholinomethyl-2-oxazolidinone (AMOZ) residues released from protein bound AMOZ in animal tissues. Polyclonal and monoclonal antibodies were produced in this study. A rapid, sensitive, and specific competitive direct enzyme-linked immunosorbent assay (cdELISA) was dev...
A comparison between the applicability of two multicomponent analysis methods, differentiation of signals and partial least squares (PLS) methods, to the resolution of overlapping differential pulse polarographic (DPP) peaks corresponding to the irreversible reduction process of two nitrofuran d...
In this study, an indirect competitive enzyme-linked immunosorbent assay with chemiluminescent (CLELISA) detection for 3-amino-5-morpholinomethyl-2-oxazolidone (AMOZ) was developed. A monoclonal antibody (MAb) against AMOZ was prepared through immunizing BALB/c mice with 4-carboxybenzaldehyle de...
Oxidative stress is closely related to the pathogenesis of ischemic stroke. Protocatechualdehyde (PCA) is a phenolic acid compound that has the putative antioxidant activities. The present study was aimed to investigate the molecular mechanisms involved in the antioxidative effect of PCA against...
Schiff base ligand (H3L) was prepared from the condensation reaction of protochatechualdehyde (3,4-dihydroxybenzaldhyde)with 2-amino phenol. From the direct reaction of the ligand (H3L) with Co(II), Ni(II) and Cu(II) chlorides, and Fe(III)and Zn(II)nitrates in 2 M/1 L molar ratio, the five new n...
