The new N-chlorodimethylsilylmethyl-N′-trimethylsilyl-N,N′-propylene urea 5 was synthesized by trans-silylation reaction of N,N′-bis(trimethylsilyl)-N,N′-propylene urea 4 with ClCH2SiMe2Cl. Mild hydrolysis of compound 5 results in the formation of N-[hydroxy(dimethyl)silylmethyl]-N,N′-propy...

The hydrogen bonding between dopamine hydrochloride (DH) and N,N-dimethyl formamide (DMF) were investigated by UV–visible spectra (UV–Vis), cyclic voltammetry (CV) and density functional theory (DFT). It was found that the position of UV–Vis absorption band and the anodic/cathodic peak potent...

Publisher SummaryThis chapter reviews that adrenochrome (l), the red oxidation product of adrenaline (2) is the best known member of the family of red to violet coloured indoline-5,6-quinones, known as the aminochromes, which are readily obtained on oxidation of the corresponding catecholamines....

Purpose: The combined effects of immunomodulators (lithium or OK432) and an adrenochrome derivative (AMM), an agent found to activate granulocyte-macrophage colony stimulating activity, on the survival of irradiated ddY mice is described.Methods and Materials: ddY mice at 4–5 weeks old were who...

1,8-Naphthalimide connected to benzoic acid chloride via methylene group was condensed separately with 3-amino pyridine and 4-amino pyridine and provided compounds 4-(1,3-Dioxo-2,3-dihydro-1H-phenalen-2-ylmethyl)-N-pyridin-3-yl-benzamide 1 and 4-(1,3-Dioxo-2,3-dihydro-1H-phenalen-2-ylmethyl)-N-p...

Type 2 diabetes mellitus (T2DM) is the most common type of diabetes, accounting for 90% of diabetic cases. It is characterized by chronic hyperglycemia which is caused by a combination of deficiency in insulin action and secretion. Adipose tissue regulates insulin sensitivity via the circulating...

Halophilic and freshwater strains of cyanobacteria representing the Oscillatoriales, Nostocales, Chroococcales, and Synechococcales orders of Cyanophyta were examined to determine (i) the resistance of their cultures when suppressed by the presence of exogenous methoxylated and methylated deriva...

A highly enantioselective (84–97% ee) cascade Michael/acyl transfer reaction of α-nitroketones to a wide range of 2-hydroxychalcones was established in the presence of a bifunctional squaramide. Although aliphatic α-nitroketones were revealed to be a class of challenging substrates with unsat...

Benzyladenine was more extensively metabolized by bean (Phaseolus vulgaris L.) roots than by bean stems and leaves. However, most of the benzyladenine absorbed by these two aerial organs was converted to a compound tentatively identified as ribosylbenzyladenine. Compared to other plant systems, ...

A series of gold(III) complexes involving differently substituted derivatives of a plant hormone N6-benzyladenine (HL1–5) is reported. The complexes have the general formula [Au(HL1–5)Cl3]∙nH2O (n = 0 for 1, 3–5; and n = 1 for 2), where N6-(2-fluorobenzyl)adenine (HL1), N6-(2-chlorobenzyl)ade...

The same traits of the apple tree and fruit are affected both by N fertilization and thinning, thus it is assumed that these two factors may interact. Nutrition may be a significant factor influencing fruit size and tree vigor, which may further affect the result of thinning with bioregulators. ...

Trials were conducted at Nubeena in Tasmania (Australia) over a two year period to develop chemical thinning programs for the European pear cultivar ‘Packham’s Triumph’ and to assess the impact of thinning chemicals on fruit quality. Chemicals examined were 80 mgL−1 ethephon and 1.0% v/v ammo...

Fruit development involves the phenomena of cell division and cell elongation. The process is signalled and regulated by the combined action of hormonal substances such as gibberellins, cytokinins and auxins. Benzyladenine (BA) in the presence of adequate internal auxin concentrations is able to...

The effect of different benzyladenine (BA) treatments which is a phyto-regulator or plant hormone on the cytology and growth of Nigella sativa L. (Black seed) and Allium cepa L. (onion) were investigated. Six concentrations of benzyladenine ranging from 5 to 55 ppm were applied for 6, 12, 18, 24...

Biological effects of hormones in both plants and animals are based on high-affinity interaction with cognate receptors resulting in their activation. The signal of cytokinins, classical plant hormones, is perceived in Arabidopsis by three homologous membrane receptors: AHK2, AHK3, and CRE1/AHK4...

The Annonaceae family presents alkaloids with ecological functions and pharmacological interest. This is the first study to evaluate if the application of plant growth regulators to seeds of this family alters the production of alkaloids over time from germination. This study was carried out in ...

Data on corresponding solid–liquid equilibrium of 6-benzyladenine in different solvents are essential for a preliminary study of industrial applications. In this paper, the solid–liquid equilibrium of 6-benzyladenine in methanol, ethanol, 1-butanol, acetone, acetonitrile, ethyl acetate, dimeth...

The aim of this study was to investigate the influence of foliar application of Moringa oleifera leaf extracts (control, 2.5% and 5% aqueous MLE, 2.5% and 5% ethanolic MLE) and/or benzyladenine (control, 50, 100 and 200 ppm BA) on the growth, fruit and oil yield and its main components and chemi...

The interaction of 2-halogenoethylamines and cinchocaine (CE), tetracaine (TE), diazoxide (DZE) and SKF 525A has been studied for the adrenergic responses of the rat vas deferens. Phenoxybenzamine (PB) and 2-SY28 normally produce a long lasting antagonism of this system while N,N-dimethyl-2-brom...

Vasa of guinea-pigs were incubated with a 2-halogenoalkylamine [14C]Sy28 30 μM, 25 mc/m-mole, before or during exposure to 3.65 mM phentolamine, extracted with 2:1 chloroform-methanol and the extracts washed. The organic (lower) phase was subjected to hydrolysis with 6 N HCl and autoradiographs...
