A promising imidazole compound was synthesized through the following route. The reaction of 5-methyl-2-phenyl-1H-imidazole-4-carbohydrazide (1) with carbon disulfide and potassium hydroxide in ethanol (80%) afforded salt (2). Refluxing (2) phenacyl bromide (3) ethanol/water (1:1) gave 2-((5-(5-methyl-2-phenyl-1H-imidazol-4-yl)-1,3,4-oxadiazol-2-yl)thio)-1-phenylethan-1-one (4) a 76% yield. stru...

objectives: the aim of this research was the development of 111in-labeled porphyrins as possible radiopharmaceuticals for the imaging of tumors. methods: ligands, 5, 10, 15, 20-tetrakis (3, 5-dihydroxyphenyl) porphyrin) (tdhpp), 5, 10, 15, 20-tetrakis (4-hydroxyphenyl) porphyrin (thpp) and 5, 10, 15, 20-tetrakis (3,4-dimethoxyphenyl) porphyrin) (tdmpp) were labeled with 111incl3 (produced from ...

TWIK-related K(+) 1 (TREK1) potassium channels are members of the two-pore domain potassium channel family and contribute to background potassium conductances in many cell types, where their activity can be regulated by a variety of physiologic and pharmacologic mediators. Fenamates such as FFA (flufenamic acid; 2-{[3-(trifluoromethyl)phenyl]amino}benzoic acid), MFA [mefenamic acid; 2-(2,3-dime...

Potassium and lithium salts of anionic B-phenylborataanthracenes, whose phenyl groups were fixed in a coplanar fashion, were synthesized. These compounds exhibited solvent-separated ion pair structures both in the crystalline state and in solution. Planarization of the phenyl moiety had a remarkable impact on the photophysical properties, such as the red-shifted absorption and intense fluoresce...

The syntheses and structures of copper(i) chalcogenone complexes are described. The homoleptic mononuclear copper(i) complexes [(IPr[double bond, length as m-dash]E)2Cu]ClO4, IPr[double bond, length as m-dash]E, 1,3-bis(2,6-diisopropylphenyl)imidazoline-2-thione (1) and 1,3-bis(2,6-diisopropylphenyl)imidazoline-2-selone (2); [(IMes[double bond, length as m-dash]E)2Cu]ClO4, IMes[double bond, len...

The micronutrient boron is essential in maintaining the structure of plant cell walls and is critical for high yields in crop species. Boron can move into plants by diffusion or by active and facilitated transport mechanisms. We recently showed that mutations in the maize boron efflux transporter ROTTEN EAR (RTE) cause severe developmental defects and sterility. RTE is part of a small gene fami...

The structural and electronic properties of nickeland phosphorus-doped boron–carbon (B5C) alloy thin films grown by plasma-enhanced chemical vapor deposition have been examined. The Ni-doped boron–carbon alloys were grown using closo-1,2-dicarbadodecaborane (C2B10H12) as the boron–carbon source compound and nickelocene (Ni(C5H5)2) as the nickel source. The phosphorus-doped alloys were grown usi...
