Various radiometal complexes have been developed for tumor imaging, especially Ga-68 tracer. In the present study, the development of a radiogallium bis-thiosemicarbazone complex has been reported. [67Ga] acetylacetonate bis(thiosemicarbazone) complex ([67Ga] AATS) was prepared starting [67Ga]Gallium acetate and freshly prepared acetylacetonate bis (thiosemicarbazone) (AATS) in 30 min at 90°...

A new precursor 2-(1-cyano-2,2-bis(methylthio)vinyl)benzonitrile has been synthesized by the reaction of 2-cyanomethylbenzonitrile, carbon disulfide and methyl iodide under basic conditions. The reaction of 2-(1-cyano-2,2-bis(methylthio)vinyl)benzonitrile with various functionalized aryl/heteroaryl methyl ketones or acetone under basic conditions afforded 4-amino-3-aroyl/heteroaroyl/acetyl-2-me...

In the title compound, C(10)H(11)NO(2)S, the acetyl-acetone group crystallizes in the keto form with all the non-hydrogen atoms in the acetyl-acetone group approximately co-planar with a maximum atomic deviation 0.055 (2) Å; the dihedral angle between the acetyl-acetone group and the pyridine ring is 85.90 (6)°. An intra-molecular O-H⋯O hydrogen bond involving the acetyl-acetone group forms a s...

gabapentin is an anticonvulsant widely used in the treatment of epilepsy.an accurate and validated spectrophotometric method was developed as an alternative method to determine gabapentin in pharmaceutical products. this is a simple, accurate, precise, selective and visible spectrophotometric method. the method is based on the measurement of drug absorbance as a result of yellow solution format...

Covalent grafting of the nanoporous molecular sieve MCM-41 with 3- aminopropyl trimethoxysilane and acetyl acetone (acac) successively gave modified MCM-41 (acacAmpMCM-41). Reaction of the resulted material with glycine afforded the corresponding supported glycine Schiff base ligand and subsequent reaction with [bis(acetylacetonato)dioxomolybdenum(VI)] was lead to molybdenum complex suppor...

Acetone degradation by cell suspensions of Desulfococcus biacutus was CO2 dependent, indicating initiation by a carboxylation reaction, while degradation of 3-hydroxybutyrate was not CO2 dependent. Growth on 3-hydroxybutyrate resulted in acetate accumulation in the medium at a ratio of 1 mol of acetate per mol of substrate degraded. In acetone-grown cultures no coenzyme A (CoA) transferase or C...
