Copper(II) complexes with new polypodal ligands presenting axial-equatorial phenoxo bridges {2-[(Bis(2-pyridylmethyl)amino)methyl]-4-methyl phenol, 2-[(Bis(2-pyr1dylmethyl)amino)methyl]-4-methyl-6-(methylthio)phenol}: Examples of ferromagnetically coupled
(2007)
Two new ligands, 2-[(bis(2-pyridylmethyl)amino)methyl]-4-methylphenol (HL) and 2-[(bis(2-pyridylmethyl)amino)methyl]-4-methyl-6-(methylthio)phenol (HSL), were synthesized and were used to prepare the trinuclear copper(II) ...
In vitro methylation of the elongation factor EF-Tu from Escherichia coli
(1985)
The in vitro methylation of the elongation factor EF-Tu from Escherichia coli was investigated. The methylation of newly synthesized EF-Tu was obtained using lambda rifd 18 DNA as template and S-adenosyl [methyl-3H]methionine ...
Reaction of 4,5-diamino-3-methyl-1-phenylpyrazole with 3-dimethylaminopropiophenones. Synthesis of new 4-aryl-6-methyl-8-phenyl-2,3-dihydropyrazolo[3,4-b]diazepines and 4-aryl-8-methyl-6-phenyl-2,3-dihydropyrazolo[4,3-b]diazepines
(HETERO CORPORATION, 1999-05)
New 4-Aryl-6-methyl-8-phenyl-2,3-dihydropyrazolo[3,4-b]diazepines and 4-aryl-8-methyl-6-phenyl-2,3-dihydropyrazolo[4,3-b]diazepines were obtained from the reaction of 4,5-diamino-3-methyl-1-phenylpyrazole 1 with one ...
3-Hydroxy-4-methyl-4-pentenonitrile and 4-methyl-3-oxo-4-pentenonitrile: Study of the tautomerics equilibria in gas phase and in solution
(Pergamon-Elsevier Science Ltd, 2010-10-01)
In the present work the tautomerics equilibria in 3-hydroxy-4-methyl-4- pentenonitrile and 4-methyl-3-oxo-4-pentenonitrile have been studied. The first compound presents two possible theoretical tautomers, nitrile and ...
Intraspecific variability of dihydrochalcone, chromenes and benzoic acid derivatives in leaves of Piper aduncum L. (Piperaceae)
(2009-05-18)
Chemical analysis carried out in leaves of 18 specimens of Piper aduncum L. (Piperaceae) occurring at Ripasa Reserve, Araraquara, SP, Brazil indicated two distinct populations when investigated over a period of 14 months ...

Human chorionic gonadotropin and free beta subunits stimulate phospholipid methylation in intact rat Leydig cells
(1993)
The effect of human chorionic gonadotropin (hCG) on intact Leydig cell phospholipid methylation was
studied. Hormonal stimulation of rat Leydig cells increased the incorporation of[methyl-3H]methionine
into phospholipids ...
Methylation pattern of THBS1, GATA-4, and HIC1 in pediatric and adult patients infected with helicobacter pylori
(2013-10-01)
Background: Helicobacter pylori infection is usually acquired in childhood and persists into adulthood if untreated. The bacterium induces a chronic inflammatory response, which is associated with epigenetic alterations ...
