Thioureas are exceptionally versatile building blocks towards the synthesis of wide variety of heterocyclic systems, which also possess extensive range of pharmacological activities. The substituted benzoic acids were converted into corresponding acid chlorides, these acid chlorides were then tr...

The photoreactivity of allyl benzoates, containing an electron-rich double bond, has been explored by irradiation at 305 nm in different solvents. Solvent addition products arising from an insertion of the alpha H–C bonds of THF, dioxane, and i-PrOH to the allylic double bond was realized. The ...

Based on the previously described antimicrobial activity of salicylanilide derivatives, we designed and synthesized novel 2-(phenylcarbamoyl)phenyl 4-substituted benzoates. The most active salicylanilides were selected for esterification by various 4-substituted benzoic acids. These compounds we...

Sodium benzoate is a widely used preservative found in many foods and soft drinks. It is metabolized within mitochondria to produce hippurate, which is then cleared by the kidneys. We previously reported that ingestion of sodium benzoate at the generally regarded as safe (GRAS) dose leads to a r...

Selective estrogen receptor modulators (SERMs) act as either agonist or antagonist of estrogen receptor (ER) in a tissue selective manner and have been used in several diseases such as breast cancer, postmenopausal syndrome, osteoporosis, and cardiovascular diseases. However, current SERMs may a...

We study 94 equity mutual funds in Israel that change their names 228 times between January 2004 and July 2014. Funds that change their names do not show superior performance in the post-name change period but attract significantly more money flows than a group of control funds. However, funds t...

4-Methoxymethamphetamine (PMMA) was synthesised from star anise and from 4-methoxytoluene and the organic impurity profiles examined. These two starting materials are unrestricted chemicals in many jurisdictions and contain the requisite functional groups and are thus well suited for clandestine...

A new method has been developed for concise synthesis of diethyl 5,5′-diaryl-2,2′-bifuran-4,4′-dicarboxylates. The preparative pathway begins with bis-C-alkylation reaction of the β-ketoester and 1,4-dibromobut-2-yne followed by hypervalent iodine (III)-mediated oxidative cycloisomerization ...

BackgroundClinical trial data suggest amphetamine treatment is most efficacious in moderate to high frequency cocaine users. However, preclinical studies have examined amphetamine treatment effects under relatively limited cocaine access conditions with low to moderate cocaine intakes. This stud...

Exposure to social stress increases the vulnerability of experimental animals to the rewarding effects of cocaine and it has been suggested that the glutamatergic system could be involved in these effects of stress. The aim of this work is to determine the role of N-methyl-d-aspartate (NMDA) glu...

Tetrahydro-1H-oxazolo[3,4-a]pyrazin-3(5H)-ones are readily prepared from the bis-carbamate protected piperazine-2-carboxylic acids and serve as orthogonally protected piperazines from which a variety of 2-substituted piperazines can be prepared. Sodium benzylate and sodium phenoxides react at th...

In this manuscript, the synthesis and biological activity of a series of pyrazole acetic acid derivatives as CRTh2 antagonists is presented. Biological evaluation in vitro revealed that the pyrazole core showed in several cases a different structure–activity relationship (SAR) to that of relate...

The characteristics of N-propyl-N′-ethoxycarbonyl thiourea (PECTU) were studied in the flotation experiments of chalcopyrite and pyrite compared with butyl xanthate (BX). The interaction mechanism between mineral and PECTU was investigated according to zeta potential and electrochemistry measur...

Metabotropic glutamate receptor 2 (mGluR2) has been suggested as a therapeutic target for treating schizophrenia-like symptoms arising from increased glutamate transmission in the human forebrain. However, no reliable positron emission tomography (PET) radiotracer allowing for in vivo visualizat...

We report here the synthesis and a combined experimental and theoretical study on molecular structure of 2-thioxo- 3N-(2-methoxyphenyl) −5 [4′-methyl -3′N -(2′-methoxyphenyl) thiazol-2′(3′H)-ylidene] thiazolidin-4-one. The crystal structure has been determined by X-ray diffraction. Crystall...

para-Methylaniline and p-chloroaniline were reacted with acryloyl chloride to produce the corresponding monomers. The two monomers were solution homopolymerized and copolymerized. The obtained homopolymers and copolymer were mixed with nitrocellulose in acetone as stabilizers under stirring to p...

The current research aims to present a straightforward synthesis of binuclear palladated triphenylphosphine derivative by the reaction of the phosphonium salt [(PhCH2)P(Ph)2(Ph-4-CH3)]Br with palladium(II) chloride and to afford the dimeric palladated complex {Pd[P(Ph)(CH2Ph)(Ph-4-CH3)]((μ-Br)B...

A series of fifteen N-phenylphthalimides including 12 4-amino- N-phenylphthalimides and three N-(3-amino-2-methylphenyl)phthalimides was prepared and evaluated for anticonvulsant properties. The compounds were tested against seizures induced by electroshock (MES) and pentylenetetrazol (scPTZ) in...

Group extraction of the metabolites of 4-acetoxy-2-(4-methylphenyl)benzothiazole has been achieved through the use of an immunoaffinity adsorbent. The antisera elicited from an immunogen, 4-hydroxy-2-(4-formylphenyl)benzothiazole O-carboxymethyloxime-bovine serum albumin conjugate, were characte...

In the search for AMPA receptor (AMPAR) antagonists, 2,3-benzodiazepines represent a family of specific noncompetitive antagonists with anticonvulsant and neuroprotective properties. We have previously shown that 2,3-benzodiazepin-4-ones possess marked anticonvulsant properties and high affinity...
