Epilepsy is a neurological disease affecting people of all ages worldwide. Side effects of antiepileptic drugs and their association with oxidative stress stimulate the search for new drugs, which would be more affordable with fewer adverse effects. Accordingly, the aim of the present work is to...
PbE (E=S, Se and Te) nanoparticles stabilized by anacardic acid in the shape of spheres and cubes have been synthesized employing a simple solution based thermolysis route at moderate reaction temperatures. The route adheres to some of the principles of ‘green’ chemistry since a naturally occu...
Cashew nuts are important both nutritionally and industrially, but can also cause food allergies in some individuals. The present study aimed to assess the effect(s) of industrial processing on anacardic acids and allergens present in cashew nuts. Sample analyses were performed using liquid chro...
Anacardic acid, which is abundant in nutshell of Anacardium occidentale, has multiple pharmacological activities. In this study, we examined the therapeutic potential of anacardic acid in treating rheumatoid arthritis (RA). We explored the effects of anacardic acid on collagen-induced arthritis ...
The behavior of the Schiff base N,N′-bis(salicylidene)-1,2-ethylenediamine (Salen), its reduced form (N,N′-bis(2-hydroxybenzyl)-1,2-ethylenediamine) and a mixture of its preceding molecules, ethylenediamine and salicylaldehyde, as carbon steel corrosion inhibitors in 1 mol L−1 HCl solution was...
The synthesis, characterization and metal ion affinities of a new multidentate ligand, N,N″-bis(2-hydroxybenzyl)-diethyl- enetriamine -N,N′,N″-triacetic acid (HBDT) are described. Protonation constants of the ligand and stability constants of its 1:1 complexes with trivalent and divalent meta...
The complexes of Fe(III), Co(III), Mn(III), Al(III), Cu(II), Ni(II), Cd(II) and Zn(II) with N,N′-bis(hydroxybenzyl)ethylenediamine-N,N′-diacetic acid (HBED) were separated by ion exchange in different modes: ion chromatography (IC) and ion electrokinetic chromatography (IEKC). In column IC the...
The X-ray crystal structures of N,N′-bis(2-hydroxybenzyl)-N,N′-bis(2-methyl-pyridyl)ethylenediamine (H2BBPEN) and the complex [Ru(BBPEN)][PF6]·H2O have been determined. In this complex the two phenolate oxygens, the two aliphatic nitrogens and the pyridine rings lie in cis positions. Two reve...
The reaction of Mn(OAc)·2H2O in methanolic solution with N,N′-bis(2-hydroxybenzyl)-N,N′-(2-pyridylmethyl)-1,3-propanediamine (H2bbppn; C29H32N4O2) affords upon addition of NH4PF6 green crystals of the monomeric [MnIII(bbppn)][PF6] (2) complex. The crystal structure of 2 has been determined by...
The stability constants of 1:1 complexes of N,N′-bis(2-hydroxybenzyl)ethylenediamine-N,N′-diacetic acid (HBED) with trivalent and divalent metal ions have been determined by potentiometric and spectrophotometric methods in KCl supporting electrolyte (0.100 M) at 25.0 °C. The log stability con...
The development of iron chelators suitable for the chronic treatment of diseases where iron accumulation and subsequent oxidative stress are implicated in disease pathogenesis is an active area of research. The clinical use of the strong chelator N,N′-bis(2-hydroxybenzyl)ethylenediamine-N,N′-d...
A simple procedure for the synthesis of functionalized 2-methyl-2,3-dihydropyran-4-ones, based on the Maitland–Japp reaction, and their diastereoselective conversion into functionalized 2-methyltetrahydropyran-4-ones has been developed. This allows access to a structural unit present in a large...
C-Glycosylations of several 2-naphthols with different glycosyl donors have been investigated in the pursuit of the total synthesis of mayamycin (1). While glycosylations of the parent 2-naphthol are readily achievable, those of 5-methoxy-7-methyl-2-naphthol (6) embodying the target are ineffect...
Conformational effects, especially the anomeric effect, were examined in 2-methoxy-−iosbutoxy, -acetoxy and −hydroxy-4-methyltetrahydropyrans as well as the correspnding derivatives of 6-methyl- and 6-oxymethyltetrahydropyran. Results are related to anomeric equilibria of xylose and glucose deri...
The reaction chemistry and kinetics of the low temperature hydroformylation of the water-soluble substrates, 4-penten-1-ol and 3-buten-1-ol, in aqueous solution utilizing the catalyst HRh(CO)(TPPTS)3 is reported where, TPPTS is trisulphonated triphenylphosphine. The reactions were carried out at...
BackgroundMethohexital and amobarbital have been used as agents for Wada testing in the presurgical evaluation of patients with epilepsy. Previous experience with methohexital as an anesthetic indicates that methohexital may decrease seizure threshold and may trigger seizures.
IntroductionMethohexital has replaced amobarbital during Wada testing at many centers. The objective of our study was to compare the use of methohexital and amobarbital during Wada testing regarding language and memory lateralization quotients as well as speech arrest times.
BackgroundECT is a well-established treatment for severe depression. The available data on psychosis are limited, but reliable. Its therapeutic potential relies on the induction of a generalized seizure. Besides other narcotics, methohexital and etomidate are used for general anesthesia in ECT. ...
BackgroundPropofol is a preferred agent for many pediatric sedation providers because of its rapid onset and short duration of action. It allows for quick turn around times and enhanced throughput. Occasionally, intravenous (IV) methohexital (MHX), an ultra-short acting barbiturate is utilized i...
A middle-aged patient underwent staged endovascular embolization of a Spetzler-Martin grade V right parietal arteriovenous malformation(AVM).In the fifth endovascular embolization, after methohexital 10 mg injection into a right posterior choroidal artery feeding the AVM nidus, there was an imme...
